Shock And Homeostasis Most cases of shock call for the administration of extra fluids and emergency medications like epinephrine to help restore perfusion to the tissues. If the body is not able to do this quickly, with or without outside help, organs will fail (kidney failure, liver failure, coma) and damage may become permanent. Remind students that perfusion is blood flow.
Circulatory Routes Blood vessels are organized into circulatory routes that carry blood to specific parts of the body. The pulmonary circulation leaves the right heart to allow blood to be re-oxygenated and to off-load CO2. The systemic circulation leaves the left side of the heart to supply the coronary, cerebral, renal, digestive and hepatic circulations (among others). The bronchial circulation provides oxygenated blood to the lungs, not the pulmonary circulation, which oxygenates blood!
