Facts About Blood

What is blood?

Blood is the life-maintaining fluid that flows through the body's blood vessels:

• Arteries

• Veins

• Capillaries

What is the function of blood?

Blood carries the following to the body tissues:

• Nourishment

• Electrolytes

• Hormones

• Vitamins

• Antibodies

• Heat

• Oxygen

Blood carries the following away from the body tissues:

• Waste matter

• Carbon dioxide

What is blood made of?

The components of human blood include:

• Plasma. This is the liquid part of blood. The following blood cells are suspended in plasma:

  • Red blood cells (erythrocytes). These carry oxygen from the lungs to the rest of the body.

  • White blood cells (leukocytes). These help fight infections and aid in the immune process. Types of white blood cells include the following:

    • Lymphocytes

    • Monocytes

    • Eosinophils

    • Basophils

    • Neutrophils

  • Platelets (thrombocytes). These help to control bleeding.

Where are blood cells made?

Blood cells are made in the bone marrow. The bone marrow is the soft, spongy material in the center of the bones. It produces about 95% of the body's blood cells. Most of the adult body's bone marrow is in the pelvic bones, breast bone, and the bones of the spine.

There are other organs and systems in our bodies that help regulate blood cells. The lymph nodes, spleen, and liver help regulate the production, destruction, and differentiation (developing a specific function) of cells.

Blood cells formed in the bone marrow start out as a stem cell. A stem cell is the first phase of all blood cells. As the stem cell matures, several distinct cells evolve. These include the red blood cells, white blood cells, and platelets. Immature blood cells are also called blasts. Some blasts stay in the marrow to mature. Others travel to other parts of the body to develop into mature, functioning blood cells.

What do blood cells do?

The mainfunction of red blood cells is to carry oxygen from the lungs to the body tissues. And to carry carbon dioxide as a waste product away from the tissues and back to the lungs. Hemoglobin is an important protein in red blood cells that carries oxygen from the lungs to all parts of our body.

The main function of white blood cells is to fight infection. There are several types of white blood cells. Each has its own role in fighting bacterial, viral, fungal, and parasitic infections. Types of white blood cells that are most important for helping protect the body from infection and foreign cells include the following:

• Neutrophils

• Eosinophils

• Lymphocytes

• Monocytes

• Basophils 

White blood cells:

• Help heal wounds. They do this by fighting infection, and also by taking in matter, such as dead cells, tissue debris, and old red blood cells.

• Are our protection from foreign bodies that enter the blood, such as allergens.

• Help to protect against changed (mutated) cells, such as cancer.

The main function of plateletsis blood clotting. Platelets are much smaller in size than the other blood cells. They group together to form clumps, or a plug, in the hole of a vessel to stop bleeding.

What is a complete blood cell count (CBC)?

A complete blood cell count (CBC) is a measurement of size, number, and maturity of the different blood cells in a specific volume of blood. A CBC can be used to determine many abnormalities with either the production or destruction of blood cells. Changes from the normal number, size, or maturity of the blood cells can be used to show an infection or disease process. Often with an infection, there will be a highernumber of white blood cells. Many forms of cancer can affect the bone marrow production of blood cells. An increase in the immature white blood cells in a CBC can be linkedto leukemia. Anemia and sickle cell disease will have abnormally low hemoglobin.

Common blood tests

Some common blood tests include the following:

Test	Uses
Complete blood count (CBC), which includes: White blood cell count (WBC) Red blood cell count (RBC) Platelet count Hematocrit red blood cell volume (HCT) Differential blood count	To help diagnose anemia and other blood disorders and certain cancers of the blood. To watch for blood loss and infection. To watch a person's response to cancer treatment, such as chemotherapy and radiation.
Platelet count	To diagnose or monitor bleeding and clotting disorders.
Prothrombin time (PT) and partial thromboplastin time (PTT)	To evaluate bleeding and clotting disorders and to monitor anticoagulation (anti-clotting) therapies.

Your healthcare provider will explain the purpose and results of any blood tests with you.

Blood production is very complex. And so is blood's role in supporting the entire body. So there are many blood diseases that can happen. These include bleeding disorders, anemias, and blood cancers called leukemias.

Is Garlic good for the heart?

Yes, garlic is good for the heart! Garlic has been used for centuries. It contains compounds like allicin, which have been shown to have various health benefits, including supporting heart health.

Garlic may help lower blood pressure, reduce cholesterol levels, and improve blood circulation, all of which are important for heart health. Additionally, garlic has antioxidant properties that can help protect the heart from damage caused by free radicals.

One of the ways garlic benefits heart health is by promoting the relaxation of blood vessels, which can help lower blood pressure. Lowering blood pressure is important because high blood pressure can strain the heart and increase the risk of heart disease and stroke.

Garlic also appears to have a positive effect on cholesterol levels. It may help lower LDL cholesterol, often referred to as "bad" cholesterol, while increasing HDL cholesterol, known as "good" cholesterol. Maintaining healthy cholesterol levels is essential for reducing the risk of heart disease.

Including garlic in your diet can be easy. You can add it to various dishes while cooking, or you can take garlic supplements if you prefer. However, it's essential to note that while garlic can be beneficial for heart health, it should not replace other heart-healthy habits like regular exercise, eating a balanced diet, and avoiding smoking.

In conclusion, incorporating garlic into your diet can contribute to maintaining a healthy heart, thanks to its various cardiovascular benefits.

How do you prove Ohm's law using the classical free electron theory?

Let's see, Ohm's law is basically the idea that the current in a conductor is proportional to the voltage across it.

You know, V=IR and all that jazz.

But how do we explain this from a microscopic point of view? What's going on inside that metal when we apply an electric field?

That's where the classical free electron theory comes in.

This thing says that a metal is made of a bunch of positive ions in a lattice and a bunch of free electrons that can move around like gas molecules.

The electrons are constantly colliding with each other and with the ions, but we don't care about the electron-electron collisions because they don't change the net momentum or current.

The electron-ion collisions, on the other hand, are important because they make the electrons lose energy and change direction.

So, when we apply an electric field to the metal, the electrons feel a force that makes them accelerate in the opposite direction of the field.

But they don't go very far before they hit an ion and bounce off randomly.

This means that they have a very small average drift velocity in the direction of the current, which is proportional to the electric field.

The current density, which is the current per unit area, is then given by J=−nevd, where n is the number of free electrons per unit volume, e is the charge of an electron, and vd is the drift velocity.

Now, we can relate the drift velocity to the electric field by using some simple physics.

The force on an electron is $F=-eE$ , where E is the electric field.

The acceleration of an electron is a=F/m, where m is the mass of an electron.

The time between collisions is t, which is also called the relaxation time. The drift velocity is then vd=at=−eEt/m/.

Putting it all together, we get J=ne2Et/m, which shows that the current density is proportional to the electric field.

This is the local form of Ohm's law.

To get the global form, we just integrate over the length of the wire and divide by its cross-sectional area.

We getV=IR, where R=m/(ne2tA), which is called the resistance.

……….

And there you have it. We just proved Ohm's law using the classical free electron theory.

Of course, this theory is not perfect and it has some limitations, but it's good enough for most purposes.

How do you heal inflamed esophagus naturally or with home remedies?

How has thin inflammation been diagnosed/proven? Only endoscopy can do that.

If really inflamed, it usually is due to acid reflux from the stomach going up into your esophagus, thus you need meds to block acid production like Histamin2 blocker like ranitidine, famotidine, or protonpump inhibitors like omeprazole, esomeprazole, pantoprazole.

You get try to support these meds by following an anti reflux diet by not eating too much at a time, not eat fatty food, not smoke (stimulates the stomach to make more acid and weaken the circular sphincter muscle between stomach and lower esophagus that prevent reflux) tomatoes, citrus fruits, mint, not eat the last 2 hours before going to sleep, prevent constipation, and sleep on your left side and/or with the head of the bed elevated by 6 to 8 inches.

Why is EARTH PIN longest and thickest ?

Electrical engineering based reason - More the thickness of wire/ conductor less is the resistance. A thick Earth Pin provides a less resistance path for the current to be grounded.

Safety based reason - Somehow this longest pin is connected properly in the electrical system than other pin (phase & neutral) and ensures safe to pass the leakage current through this earth pin rather than a person operating an applice.

Why is our car misfiring after changing spark plugs and coils?

There are several potential causes for a car misfiring after changing spark plugs and coils. It is possible that the spark plugs were not properly gapped, or that the spark plugs are not the correct type for the vehicle. It is also possible that the spark plug wires are not connected properly, or that the ignition coil is not functioning correctly.

To diagnose and fix the problem, you will need to do some basic checks and tests. Here are some steps you can follow:

First, check the condition of the spark plugs and wires. Look for any signs of damage, corrosion, or wear. Make sure that the spark plugs are gapped according to the manufacturer’s specifications, which you can find in your owner’s manual or online. You can use a feeler gauge or a spark plug gap tool to measure the gap. If the gap is too wide or too narrow, adjust it accordingly. You can also use a multimeter to test the resistance of the spark plug wires, which should be within the range specified by the manufacturer. If you find any faulty spark plugs or wires, replace them with new ones.

Second, check the condition of the ignition coil. The ignition coil is responsible for generating a high-voltage current that ignites the air-fuel mixture in the cylinders. If the ignition coil is defective, it can cause weak or inconsistent sparks, resulting in misfires. You can test the ignition coil by using a spark tester, which is a device that simulates a spark plug and shows if there is a spark or not. You can also use a multimeter to measure the primary and secondary resistance of the ignition coil, which should be within the range specified by the manufacturer. If you find any signs of damage or malfunction in the ignition coil, replace it with a new one.

Third, check for any other possible causes of a misfire, such as bad fuel injectors, vacuum leaks, or carbon build-up. These issues can affect the quality and quantity of the air-fuel mixture in the cylinders, leading to incomplete combustion and misfires. You can use a fuel pressure gauge to test the fuel pressure and flow from the fuel pump to the injectors. You can also use a vacuum gauge to test for any leaks in the intake manifold or hoses. You can also use a compression tester to test for any loss of compression in the cylinders due to carbon deposits or worn piston rings. If you find any problems with these components, you will need to clean, repair, or replace them as needed.
