explain how oxygenated blood from left Atrium is sent to all part of body
Answers
Answer:
Explanation:
Actually oxygenated blood from left ventricle is sent to all parts of the body. As the oxygenated blood is brought to the left auricle(or left atrium as you mentioned)from the lungs through the pulmonary artery, it gets pumped to the left ventricle and the valve closes which is also responsible for lub dub sound in your heart. This prevents backward flow of blood. The left ventricle than contracts and expands to pump the blood to the Aorta which is the largest artery in your body which in turn carries oxygenated blood to all part of the body by branching into arteries ,arterioles and capillaries
Please mark this as the brainliest answer
Answer: Left Atrium receives oxygenated blood through the pulmonary vein. The atrium has a thin wall. The blood is collected in the left atrium when the left atrium relaxes. As soon as the left atrium contracts, the bicuspid valve opens and the left ventricle expands and blood is transferred to the left ventricle. Then, the left ventricle contracts the aortic valve opens and the blood moves to to the aorta and is pumped to all the other parts of the body.
