Blood flow within the heart follows a specific pathway: deoxygenated blood returns from the body to the right atrium, moves into the right ventricle, and is pumped to the lungs via the pulmonary arteries for gas exchange. In the lungs, carbon dioxide is released, and oxygen is absorbed into the blood. The now oxygenated blood returns to the left atrium, flows into the left ventricle, and is then pumped out to the body through the aorta. This continuous cycle ensures that oxygen-rich blood is delivered to tissues while facilitating the removal of carbon dioxide.
how does the heart work
exchange of gases and nutrients in the blood; pumps blood and controls heart
The systemic circulation is the part of the circulatory system that carries oxygenated blood away from the heart to the body and returns deoxygenated blood back to the heart. In contrast, the pulmonary circulation is the part of the circulatory system that carries deoxygenated blood from the heart to the lungs for oxygenation and returns oxygenated blood back to the heart.
oxygen-poor blood is pumped through the pulmonary arteries to the lungs. gas exchange occurs in the lungs and the oxygenated blood is then returned to the left side of the heart through pulmonary veins
it works
They are small blood vessels that take deoxygenated blood to the heart. Gas exchange.
it pumps blood threw your heart
Systemic circulation: Carries oxygenated blood from the heart to the body tissues and returns deoxygenated blood back to the heart. Pulmonary circulation: Moves deoxygenated blood from the heart to the lungs for oxygenation and returns oxygenated blood back to the heart. Coronary circulation: Supplies oxygen and nutrients to the heart muscle itself through a network of blood vessels.
The blood vessels that carry blood to the heart are called veins. There are two other kinds of blood vessels. Capillaries allow body tissues to exchange water and chemicals with blood, and arteries carry blood away from the heart and back out to the body.
If you do not breathe the blood in your veins and arteries can not flow. The exchange of CO2 and oxygenated blood can not mix and exchange in the heart. The gas from CO2 will suffocate you and you will die.
Arteries - carry blood away from the heart Veins - carry blood back to the heart Capillaries - allow the exchange of water/chemicals between blood and tissues
The heart pumps blood to the lungs to be reoxygenated. Valves in our veins and the muscle contractions of our legs helps bring blood from the lower limbs to the heart.
