Document Summary
What is the role of blood in physiology: blood distributes hormones, nutrients, gasses, waste products and immune system components. Plasma- the colorless fluid part of blood, lymph, or milk, in which corpuscles or fat globules are suspended. Red blood cells (erythrocyte)- a red blood cell that (in humans) is typically a biconcave disc without a nucleus. Erythrocytes contain the pigment hemoglobin, which imparts the red color to blood, and transport oxygen and carbon dioxide to and from the tissues. White blood cells (leukocyte)- a colorless cell that circulates in the blood and body fluids and is involved in counteracting foreign substances and disease; a white (blood) cell. There are several types, all amoeboid cells with a nucleus, including lymphocytes, granulocytes, monocytes, and macrophage. Platelets-a small colorless disk-shaped cell fragment without a nucleus, found in large numbers in blood and involved in clotting. Coagulation-cause (a fluid) to change to a solid or semisolid state.
