What is the use of diaphragm |
| Answer» \tThe diaphragm in the respiratory system is the dome shaped sheet of muscle that separates the chest from the abdomen.\tDuring inhalation the diaphragm contracts and moves in the inferior direction, thus enlarging the volume of the thoracic cavity.\tThis reduces the pressure in the lungs and air enters into lungs.\tDuring exhalation the diaphragm relaxes and assumes its dome shape. This change increases the pressure on the lungs and squeezes the air out through the nose to the external atmosphere. | |

Q.explain the double circulation in short? |
|
Answer» Thanks bro In human beings, the blood goes through the heart twice during each cycle i.e. the blood passes through the human heart two times to supply once to the whole body. So, it is called Double Circulation of blood.The double circulation of blood includes:(i) Systematic Circulation(ii) Pulmonary CirculationSystematic Circulation: It supplies oxygenated blood from left auricle to left ventricle, thereby pumped to various body parts. The deoxygenated blood is collected from the various body organs by the veins to pour into vena cava and finally into the right atrium (auricle). Right atrium transfers the blood into the right ventricle.Pulmonary Circulation: The deoxygenated blood is pumped by the right ventricle into the lungs for oxygenation. The oxygenated blood is brought back to left atrium (auricle) of the human heart. From left atrium, the oxygenated blood is pushed into the left ventricle. The left ventricle pumps oxygenated blood into aorta for systematic circulation. |
