Coronary circulation

The human body is composed of eleven major systems that all work together to hold a stable internal environment: homeostasis. Each system consists of different organs that all play important roles in maintaining homeostasis. The circulatory, respiratory and renal systems greatly affect each other in the keeping of the internal environment. Homeostasis is defined as the tendency of an organism or a cell to regulate its internal conditions, usually by a system of feedback controls, so as to…

With hypertension, cardiac output and stroke volume decreases as heart rate and peripheral resistance increases due to overcompensation of the heart (Huether & McCance 2012). When the heart beats, it propels blood through the arteries to increase circulation throughout your entire body. Higher blood pressures mean that with each beat, arteries throughout the body swell and stretch more than they would normally. Stretching of the endothelium, the delicate lining of all arteries, can cause injury…
