Question

explain how heart works.

Answer 1

There are two process which involve in r working of the heart, systemic and pulmonary circulation. in systemic , the body organs are involved , in pulmonary circulation lungs are involved. the blood from left auricle to left ventricle passed which is oxygenated blood , the aorta carried oxygenated blood to the organs. the vena cava, took deoxygenated blood from organs

Answer 2

Heart is divided into two separate pumping systems, the right side and the left side.

⭕The right side of our heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide.The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.

⭕Our heart has four separate chambers that pump blood, two on the right side and two on the left.



Blood flows through your heart and lungs in four steps:

⭕ The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle through the tricuspid valve.The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve.

⭕The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve.The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.

⭕The left and right atria are smaller chambers that pump blood into the ventricles. The left and right ventricles are stronger pumps. The left ventricle is the strongest because it has to pump blood out to the entire body.

⭕When your heart functions normally, all four chambers work together in a continuous and coordinated effort to keep oxygen-rich blood circulating throughout your body. Your heart has its own electrical system that coordinates the work of the heart chambers (heart rhythm) and also controls the frequency of beats (heart rate).
