The cardiovascular system consists of : heart (심장)‚ and vessels (혈관)‚ arteries (동맥)‚ capillaries (모세혈관) and veins (정맥). A functional cardiovascular system is vital (필수적인) for supplying oxygen and nutrients to tissues and removing wastes from them. Paths of Circulation: Pulmonary(폐의) Circuit : carrying blood to the lungs and back 1. The pulmonary circuit is made up of vessels that convey blood from the right ventricle to the pulmonary arteries to the lungs‚ alveolar capillaries‚ and pulmonary veins

Unit 5 task 3 (P5 M2 D2) – explain the concept of homeostasis‚ discuss the probable homeostatic response to changes in the internal environment during exercise‚ how homeostatic mechanisms control temperature‚ breathing and heart rate and evaluate the importance of homeostasis in maintaining healthy functioning of the body. Homeostasis Homeostasis is the maintenance of a constant internal environment in organisms. It involves volume of blood and tissue fluid within restricted limits‚ it also maintains

effective and ultimately leaving more residual blood in the left ventricle meanwhile decreasing stroke volume and increasing blood pressure. Increased pressure causes the left ventricle to hypertrophy which also puts pressure on the left atria. Atrial pressure is meant to be low so when ventricular pressure rises‚ it ends up transmitting pressure all the way back to the pulmonary venous circuit. The pulmonary venous system is normally meant to bring oxygenated blood back to the left side of the

Introduction Cardiac transplantation‚ also called heart transplantation‚ has evolved into the treatment of choice for many people with severe heart failure (HF) who have severe symptoms despite maximum medical therapy. Survival among cardiac transplant recipients has improved as a result of improvements in treatments that suppress the immune system and prevent infection. Definition A heart transplant‚ or a cardiac transplantation‚ is a surgical transplant procedure performed on patients
