Question

1) Explain the physiological response to damage of the blood vessel structure in different contexts (atherosclerosis, chronic venous disease, blood vessel rupture)..

Answer 1

Physiological responses in atherosclerosis

In atherosclerosis when damage to blood vessel take place inflammatory response takes place . Migration of the inflammatory cells as well as T lymphocytes , monocytes and platelet . Fibrosis of atherosclerosis might occur in most of the condition.

. chronic venous disease

In this case the valves become incompetent and blood flows back to downward direction. Body trys to cause dilation of blood vessel to reduce the pressure and help in the return flow of blood to the atrium.

Blood vessel rupture

When blood vessel rupture occur the body cause vasoconstriction in the specific region where the rupture has taken place . Then the movement of platelet and fibrin propagation to damaged area occur. Then the cloating factor and thrombin as well as platelet plug cause stoping of bleeding. After few days healing will be complete
