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.
Apr 13, 2024 · The path of blood flow through the heart and lungs is pulmonary circulation, while the blood supply to the heart itself is coronary circulation. Pulmonary Circulation: Purpose: Pulmonary circulation is responsible for oxygenating the blood. It involves the movement of deoxygenated blood from the right side of the heart to the lungs and then ...
Jul 16, 2024 · Oxygenated blood from the left side of the heart gets pumped out of the aorta. From there, blood flows through arteries, arterioles, and then capillaries (tiny blood vessels that transport blood, nutrients, and oxygen to cells). Deoxygenated blood from the capillaries then flows back to the heart through venules, veins, and ultimately through ...

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.
Blood Flow. All blood enters the right side of the heart through two veins: The superior vena cava (SVC) and the inferior vena cava (IVC) (see figure 3). The SVC collects blood from the upper half of the body. The IVC collects blood from the lower half of the body. Blood leaves the SVC and the IVC and enters the right atrium (RA) (3).
