Function of heart in 500 words ❤ |

Answer» Answer: Heart is a conical muscular DOUBLE pump structure that brings about circulation of blood in the body. There are four chambers. Deoxygenated blood from the whole body enters right auricle through a superior vena cava (from upper parts of the body), inferior vena cava (from MIDDLE and lower parts of the body) and coronary sinus (from the walls of the heart). Oxygenated blood is CARRIED by pulmonary veins into left auricle from lungs. On being filled, the two AURICLES contract simultaneously and pass their bloods into ventricles, deoxygenated in right ventricle and oxygenated in left ventricle. The distended ventricles now undergo contraction or systole forcefully. Right ventricle passes blood to pulmonary arch which divides to form pulmonary arteries. Pulmonary arteries take the deoxygenated blood to lungs. Left ventricle passes blood to aorta that supplies oxygenated blood to all parts of the body. Hope this HELPS! |
