 Blood

What is blood?

Blood is the liquid portion of our bodies that carries oxygen and nutrients throughout our body. It consists of red blood cells, white blood cells, platelets, plasma, and lymphocytes. Red blood cells carry oxygen while white blood cells fight infections. Platelets help stop bleeding and keep us alive after injuries. Plasma is the fluid portion of blood that contains water, salt, sugar, protein, and hormones. Lymphocytes are the immune system's white blood cells that protect us from disease.

 

Why do we need blood?

We need blood to live because it transports oxygen and nutrients around the body. Without blood, we would not survive long enough to reproduce.

 

Where does blood come from?

The majority of blood comes from two places: the liver and bone marrow. The liver produces about 5 quarts (about 4 liters) of blood each day. Bone marrow makes about 1 quart (about 1 liter) of blood each day, but only if it receives stimulation.

 

How much blood do we have?

A normal adult human has between 6-8 quarts (about 6-8 liters) of blood in their circulatory system. A newborn baby has about 15 quarts (about 14 liters).

 

Do we lose blood?

Yes, we lose some blood daily. Our kidneys filter out about 500 milliliters (about 2 cups) of blood per day. We also lose blood when we exercise.

 

Can we make blood?

No, we cannot make blood. However, stem cells can become any type of blood cell. Stem cells are immature cells that can develop into many different types of cells.

 

What happens when we get injured?

When we get hurt, the body sends signals to the brain to slow down the heart rate and breathing. This helps prevent further injury and keeps the blood flowing to the area where the injury occurred. If there is severe damage, the body stops the flow of blood completely until the wound heals.

What are the types of blood?

Red Blood Cells (RBC)

Red blood cells are the most abundant type of blood cells in the human body. They carry oxygen throughout the body and help maintain normal cellular function. RBCs are the most commonly seen blood cells in a microscope and have a diameter of about 6-8 micrometers.

 

White Blood Cells (WBC)

White blood cells are the second most abundant type of blood cell. They are responsible for fighting off foreign invaders and maintaining immune system function. WBCs are also called leukocytes and they are the most numerous type of white blood cells. Their size ranges between 4-10 micrometers.

 

Platelets

Platelets are small fragments of bone marrow that aid in clotting blood. They are formed in the bone marrow and released into the bloodstream where they play a role in hemostasis. Platelets are approximately 2-3 micrometers in diameter.

 

Plasma

Plasma is the liquid portion of blood. It contains water, electrolytes, hormones, antibodies, enzymes, and other substances. Plasma is separated from whole blood after red blood cells are removed.

 

Erythrocyte

Erythrocytes are the third most abundant type of blood. They are responsible for transporting oxygen and carbon dioxide throughout the body. They are the smallest blood cells and range in size from 5-9 micrometers.

 

Lymphocyte

Lymphocytes are the fourth most abundant type of blood and are responsible for defending the body against disease. They are the largest blood cells and range in diameter from 10-15 micrometers.

 

Thrombocyte

Thrombocytes are the fifth most abundant type of blood, and are responsible for forming clots. They are the largest type of blood cells and range in length from 15-20 micrometers.

Blood Pressure Monitor

A blood pressure monitor is a device that measures your blood pressure. A doctor may use a blood pressure monitor to check if you have high blood pressure. To measure your blood pressure, you need to put your arm in a special cuff that wraps around your upper arm. Then, you should place a small tube in your elbow to collect a sample of blood. After that, you should press a button on the machine to start measuring your blood pressure.

 

Blood Type O

The type of blood you have determines what kind of medical treatment you will receive. Your blood type is determined by the chemicals on the surface of your red blood cells. People who have type O blood have no antigens (foreign substances) on their red blood cells. People with type B blood have two antigens on their red blood cells, while people with type AB blood have four antigens.

 

Blood Transfusion

If someone has donated blood to you, they might ask you to donate blood to them. In order to donate blood, you need to contact your local Red Cross chapter. You can find out how to donate blood by visiting www.redcross.org.

 

Blood Types

There are four types of blood: O positive, A negative, B positive, and AB positive. Each person has only one type of blood. If you want to know your blood type, you can take a quick test at home. All you need to do is prick your finger with a lancet, let some blood fall onto a piece of paper, add a few drops of saline solution, then add a drop of anti-coagulant. Once the blood dries, look at the pattern formed by the blood droplets. If you don't know what blood type you have, you can get tested at a lab.

 

Blood Pressure

Your blood pressure is measured using a sphygmomanometer. Sphygmomanometers are devices that measure blood pressure. To measure blood pressure, you need a stethoscope, a sphygmomanometric cuff, and a mercury manometer. First, wrap the cuff around your upper arm. Next, put the stethoscope over your brachial artery. Finally, press the bulb of the manometer down until it touches your skin. Read the number on the manometer.
