Calcium Channel BlockersIII. AngiogenesisIV. Development of Blood VesselsV. Aging and the CV SystemVI. HomeostasisCurrent LectureBlood Vessels Day 3I. Alpha Blockers: prevent vasoconstriction in peripheral veins –bind and prevent other molecules to be able to bind to that receptorII. Calcium Channel Blockers: - Targets smooth muscle cellso Smooth muscle in blood vesseels contracts lesso Dilation of arterieso Lower blood pressureo Smooth muscle contracts by binding to calcium so when block calcium, no smooth muscle contractionIII. Angiogenesis: Occurs when short-term autoregulation cannot meet tissue nutrient requirements- The number of vessels to a region increases and existing vessels enlarge- Common in the heart when a coronary vessel is occluded, or throughout the body in people in high-altitude areas- Can change organization of vessels when occluded vessels at a tissue- can reorganize- never as good as the originalIV. Devolopment of Blood Vessels:V. Aging and the CV System- Loss of compliance of the aorta- Reduction in cardiac muscle fiber size- Progressive loss of cardiac muscular strength- Decline in maximum heart rate- Increased systolic blood pressureVI.
