Explanation / Answer

Physical characteristic and regulatory functions of blood:

Physical characteristic of blood:

Regulatory function of blood: Blood participates in the regulation of body temperature, body pH, and fluid balance

Compare and contrast erythrocyte and leukocyte:

Both are essential components of the blood

RBCs, also called erythrocytes, have a protein called hemoglobin. The blood gets its color when hemoglobin absorbs oxygen from the lungs. As the blood travels through the body, the hemoglobin releases the oxygen in the tissues. RBCs have a life cycle of 4 months and they appear in the form of flat indented discs.

The WBCs, also called leukocytes, handle more complex functions. They are the defense mechanism of the human body for fighting infections. There are different types of WBCs with varied life cycles and distinct functions. White blood cells also produce a special protein called antibody which recognize and fight the presence of foreign elements in the body.

A granulocyte is a white blood cell that has granular cytoplasm.Agranulocytes are white blood cells that lack cytoplasmic granules. Name five types of leukocytes, and list the major functions of each type.

Name of heart wall;

Epicardium, myocardium, endocardium
