Study Notes

Blood Function and Composition

Blood has various functions, but it does not store nutrients.

Plasma Composition

Plasma is the liquid part of blood, making up about 55% of total blood volume.
Water is the major component of plasma, accounting for about 92%.

Blood Cells

Platelets are small, irregularly-shaped blood cells that play a vital role in blood clotting.
Blood cells are produced in the red bone marrow in adults.

Erythrocytes (Red Blood Cells)

Erythrocytes, also known as red blood cells, are disk-shaped cells that lack a nucleus.
The main function of erythrocytes is to carry oxygen from the lungs to the body's tissues.

Leukocytes (White Blood Cells)

Leukocytes are an essential part of the immune system, helping to defend the body against infection.

Blood Circulation

When plasma leaves the circulatory system, it becomes interstitial fluid.
The approximate volume of blood in adults is 5 liters (11.3 pints).

Platelet Function

Platelets help to form blood clots and stop bleeding when a blood vessel is injured.
