Chapter 19: Blood Flow Through Capillaries and Capillary Dynamics, and Circulatory Shock o Capillaries Key:  Blood Pressure becomes extremely low  Fed by arterioles (5 mL of mercury)  Important Terms  Made of Tunica Intima ONLY (very thin)  Diseases  If high blood pressure were to pass  Hormones through capillaries they would rupture  Too much fluid could be loss into the intercellular spaces (which influences the blood volume) o Veins  Low pressure conditioned blood vessels  Functional Adaptations 1) Skeletal Muscle Pump  Skeletal muscle activity that influence the veins running through them  Milking Action: contraction of skeletal muscles help push blood in squeezed veins up into the heart o The Proximal Valve are opened by the pulling of the flaps towards the all of the vein o Backflow of the blood causes the Distal Valve to close 2) Respiratory Pump  Inhalation and Exhalation  Diaphragm under resting condition is in a dome shaped o During inhalation; becomes flat  Volume of
