PHYSIOL 1 Lecture Notes - Lecture 30: Skeletal Muscle, Vasodilation, Cardiac Output
Document Summary
When loss of blood volume leads to low blood pressure, when your body has two important compensatory mechanism. Decrease in capillary hydrostatic pressure, increase fluid absorption. Rbcs can be recovered by increase in erythropoietin hormone. Hemorrhage is not the only potential cause of fluid volume loss; can also occur to sodium loss (sweating) Hypotension can also occur due to a weakened heart, strong emotion, of release of vasodilators. Shock: is the medical term given to any situation is which. Bp has dropped far enough to comprise blood flow to tissues. When upright, gravity acting on the columns of blood in our cv system decrease venous return. Increase in distension of the compliance veins in our legs. Also increase in filtration from capillaries, which decrease blood volume and venous return. Body responds the same way it responds to hemorrhage. If the body doesn"t respond, you faint.
