What is blood?

Blood is a body fluid in the human body that circulates and delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells. Blood is essential to life. Blood is mostly liquid, with numerous cells and proteins suspended in it, making blood “thicker” than pure water. The average person has about 5 liters of blood (more than a gallon). There is no substitute for blood. It cannot be made or manufactured. Generous blood donors are the only source of blood for patients in need of a blood transfusion.

Blood Components

The human blood comprises of four basic components which are: red blood cells, platelets, plasma and white blood cells.

Red Blood Cells

Red blood cells (erythrocytes) represent 40%-45% of your blood volume. They transport oxygen from your lungs to your tissues and organs. They are generated from your bone marrow at a rate of four to five billion per hour. They have a lifecycle of about 120 days in the body.

Platelets

Platelets are an amazing part of your blood. Unlike red and white blood cells, platelets are not actually cells but rather small fragments of cells. Platelets help the blood clotting process (or coagulation) by gathering at the site of an injury, sticking to the lining of the injured blood vessel, and forming a platform on which blood coagulation can occur. They are the smallest of our blood cells and literally look like small plates in their non-active form.

Plasma

Plasma is the liquid portion of your blood. Plasma is yellowish in color and is made up mostly of water, but it also contains proteins, sugars, hormones and salts. The proteins help blood to clot, transport substances through the blood, and perform other functions. Blood plasma also contains glucose and other dissolved nutrients.

White Blood Cells

Although white blood cells (leukocytes account for only about 1% of your blood, they are also essential because they are part of your immune system. White blood cells are important for good health and protection against illness and disease. Like red blood cells, they are constantly being generated from your bone marrow. They flow through the bloodstream and attack foreign bodies, like viruses and bacteria. They can even leave the bloodstream to extend the fight into tissue. Some white blood cells live less than a day, but others live much longer.
