Write 4 functions of heart |
|
Answer» \tThe right atrium receives blood from the upper and lower body through the superior vena cava and the inferior vena cava, respectively, and from the heart muscle itself through the coronary sinus. The right atrium is the larger of the two atria, having very thin walls. The right atrium opens into the right ventricle through the right atrioventricular valve(tricuspid), which only allows the blood to flow from the atria into the ventricle, but not in the reverse direction.\tThe right ventricle pumps the blood to the lungs to be reoxygenated.\tThe left atrium receives blood from the lungs via the four pulmonary veins. It is smaller than the right atrium but has thicker walls. The valve between the left atrium and the left ventricle, the left atrioventricular valve(bicuspid), is smaller than the tricuspid. It opens into the left ventricle and again is a one-way valve.\tThe left ventricle pumps the blood throughout the body through the aorta, which\xa0is the\xa0largest artery in the body. The walls of the left ventricle are the thickest among all the chambers. The heart has four chambers: two atria and two ventricles. The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle. The right ventricle pumps the oxygen-poor blood to the lungs. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle. Google hai naa vha dekh loo yha koi nahi btayega ??............ Ab or science nhi???

Why does the cord of an electric ovan not glow while its heating element does? |
| Answer» Cord is made up of an inner conducting wire of low resistance and an outer covering of insulating material. Since the conducting wire has low resistance, the electric energy is converted to heat to far less extent than in the heating element which is often a very high resistance material.So,the heat energy shows as the increasing temperature of the heating element, and the temperature becomes so high that the radiation of the heat falls in our visible range, hence we see glowing heating element. | |
