What is the function of A) nasal cavity b) diaphragm c) alveoli |
|
Answer» A. It is used to remove the dust particles before entering into lungsB. It is used to maintain the pressure of lungsC. It is the site for the exchange of gases My pleasure thanku to all for the answer.... The function of alveoli is to get oxygen into the blood stream for transport to the tissues, and to remove carbon dioxide from the blood stream........ I hope u clear it.. ?? Diaphragm - The diaphragm is the major muscle of respiration. As the diaphragm contracts, it increases the length and diameter of the chest cavity and thus expands the lungs. This reduces the pressure outside the lungs. To equalize the pressure, air enters the lungs. When the diaphragm relaxes and moves back up, the elasticity of the lungs and chest walls pushes air out of the lungs. A) Nasal cavity1 It is a passage from which the air enters in the body. 2 In this passage air is filtered, the dust particles and small organisms does not enter the body. 3 It makes the cold air favorable to our body temperature. B) Diaphragm 1 It contracts makes lungs push upword to increase the surface area to such maximum oxygen. 2 It relaxes and alow the lungs to push out the carbon dioxide out of the longs. C) Alveoli1) It increases the surface area for absorption of oxygen. 2) It exchange the oxygen and carbon dioxide from the blood vessel. Alveoli - alveoli are tiny sacs within our lungs that allow oxygen and carbon dioxide to move between lungs and blood stream. Nasal cavity - The function of nasal cavity is to warm, moisture and filter air entering the body before it reaches the lungs. |
