Document Summary
Components: transport medium : blood ( liquid connective tissue , pressure maker : heart, pathways : vasculature or blood vessels. Role in homeostasis: map, total body h2o content, body temperature. When pa > pb blood flows towards b ( high 10w ) When dp = 0 no blood flow ( when pa = pb) Vasoconstriction t resistance , t blood flow. " vasodilation t resistance , t blood flow. " cardiac output f heart rate ( beats 1mm , cardiac output co = hr x sv t ( met min ) stroke volume( mel beat) Blood pressure : force of blood pushing against walls of vessel ( heart chambers , blood vessel ) Ventricular pressure : blood pressure in ventricles blood. Arterial pressure : pressure in elastic arteries , generally in the systemic circulation. Sbp : systolic blood pressure: dbp : diastolic blood pressure. Venous pressure : pressure inside the veins , usually peripheral veins.
