inferior vena cava.
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.
Most of the trunk and the lower limbs
The inferior vena cava brings blood from the lower parts of the body to the heart. The blood is deoxygenated.
The ventricles is the lower heart chambers not the blood vessels that direct blood toward the heart.
Heart blood vessels is what collects blood and pumps it to the lower chamber. This is what keeps the heart in working function.
Ventricles
The ventricles are the lower chambers of the heart. The atria are the upper chambers.
Blood coming from the lungs has lower pressure while that from the heart has higher pressure. Blood coming from the lungs also has higher oxygen content and lower carbon dioxide content compared to that coming from the heart.
An artery is an elastic blood vessel that transports blood away from the heart. There are two main types of arteries: pulmonary arteries and systemic arteries. Pulmonary arteries carry blood from the heart to the lungs where the blood picks up oxygen. The oxygen rich blood is then returned to the heart via the pulmonary veins. Systemic arteries deliver blood to the rest of the body. The aorta is the main systemic artery and the largest artery of the body. It originates from the heart and branches out into smaller arteries which supply blood to the head region, the heart itself, and the lower regions of the body.
The lower chambers of the heart have a different function than the upper chambers. The lower chambers pump the blood out of the heart into the body and lungs.
