BIOL 1107 Study Guide - Midterm Guide: Carbonic Anhydrase, Proximal Tubule, Extracellular Fluid
Document Summary
As active muscles use up oxygen, ph drops because co 2 and h 2 o form bicarbonate and h + via carbonic anhydrase and hemoglobin"s affinity for oxygen is decreased. Carbonic anhydrase converts co 2 into bicarbonate ions to. Maintain a gradient of co2 into the rbcs. Interstitial fluid diffuses through the capillaries to. Decrease pressure within capillaries to avoid bursting through the thin walls. Arterioles constrict to bring blood to the most important parts of the body. Effectors will signal for ventricles to increase stroke volume. Effectors will signal for the sa node to increase heart rate via contractions. Arteriosclerosis: cardiovascular disease in which blood vessels have hardened and lost elasticity. Atherosclerosis: gradual plaque buildup within the lumen of the artery, mainly caused by poor diet. The most villi and microvilli are found in the proximal tubule. As h 2 o and nacl leave the loop of henle passively, the countercurrent exchange between the loop of.
