Reduced blood volume leads to collapsing vessels, reduced pressure, and subsequently reduced perfusion pressure. The cardiovascular system combats low blood volume by constricting blood vessels until the body reaches a blood pressure that restores proper perfusion pressure.
a sudden, sometimes temporary, cessation of function of the heart.
Answer:
Immune modulators are the chemical agent that alters the immune system by stimulation or inhibition of the white blood cell activity.
Explanation:
A chemical agent that alters the immune response known as immune modulators. Immune modulators can stimulate or inhibit white cell activity or immune response, It is generally suggested in the poor immune systems because of disease like AIDS or rheumatoid arthritis.
The immune-suppressants use in the case of organ transplant to inhibit the white cell activity because it is a chemical agent that inhibits the white cell activity or immune response.
Thus, the immune suppressants are the agent that only inhibit the immune response whereas the immune modulator can stimulate or inhibit the immune response.
Answer:
Endosteum
Explanation:
The hollow region in diaphysis is known as medullary cavity which is filled with the yellow marrow.
<u>The endosteum is the thin vascular membrane of the connective tissue which lines up inner surface of bony tissue which forms medullary cavity of the long bones.</u>
Endosteal surface is reabsorbed usually during the long periods of malnutrition and thus resulting in the less cortical thickness.
