MEDN2001 Lecture Notes - Lecture 4: Endoplasmic Reticulum, Intercalated Disc, Cardiac Output
Document Summary
Cardiac output from the left side of the heart is the systemic blood flow. How much blood is being pumped each minute is blood flow. Cardiac output from the right side of the heart is the pulmonary blood flow. Volume of blood pumped by each ventricle in one minute. Co (cardiac output) = heart rate (hr) x stroke volume (sv) Sv = volume of blood pumped out by a ventricle with each beat. Blood flow problem is the generation of enough pressure for the liquid to flow from one side to another. It"s going move from high pressure to low pressure (like osmosis wants to move from high concentration to low concentration) Resistance is proportional to the length of the tube, the longer the tube the more resistance. Measures range of the force pushing against the vessel walls. Systolic bp corresponds to the contraction of the ventricle (120 mmhg) Diastolic bp corresponds to the relaxation of the ventricle (80 mmhg)
