Human Circulatory System Stylized Heart Anatomy Structure Blood Flow Blood flow through the body delivers oxygen, nutrients, hormones, cells, products of defense mechanisms for wound healing, and platelets. the heart pumps these products to the organs, while the vessels transport them to and from the organs. arteries perfuse the organs and veins drain the organs of waste products. the lymphatic system helps in draining excess tissue fluid to the bloodstream. Blood flows through your heart, lungs and body in a series of steps. after delivering oxygen and nutrients to all your organs and tissues, your blood enters your heart and flows to your lungs to gain oxygen and get rid of waste. it then flows back to your heart, which pumps the refreshed blood out through your aorta to nourish your body again.
Human Bloodstream Didactic Board Of Anatomy Of Blood System Of Human The circulatory system (cardiovascular system) pumps blood from the heart to the lungs to get oxygen. the heart then sends oxygenated blood through arteries to the rest of the body. the veins carry oxygen poor blood back to the heart to start the circulation process over. your circulatory system is critical to healthy organs, muscles and tissues. The blood is collected from the capillaries by venules, which unite to form the veins of the systemic circulation. these veins ultimately drain to the right atrium via the superior and inferior venae cavae. coronary circulation. the coronary circulation refers to the blood supply to the heart itself. it is a component of the systemic. The circulatory system works thanks to constant pressure from the heart and valves throughout the body. this pressure ensures that veins carry blood to the heart and arteries transport it away. Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen poor blood from the body into the right atrium of the heart. as the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve. when the ventricle is full, the tricuspid valve shuts.
