Two friends are eating togeather on a dinning table. One of them suddenly starts coughing while swallowing some food. This coughing would have been due to improper movement ofA. diaphragmB. neckC. tongueD. epiglottis |
|
Answer» Correct Answer - D The epiglottis is a flap that is made up of elastic cartilage tissue covered with a mucous membrane, attached to the entrave of the larynx. It prevents the entry of food into larynx, and directs it to the oescphgus. Due to improper movement of epiglattis, one may suddenly start coughing, while swallowing some food. |

Assertion : Gill-lamellae in aquatic animals help in exchange of gases. Reason : Each gill lamella carries many blood capillaries. |
|
Answer» Correct Answer - a Gills are the main respiratory organs of aquatic animals. Each gill bears rows of comb- like , soft , thin gill -filament, each gill - lamellace. Each gill lamella carries many capillaries. Water taken through the mouth , is made to flow from the pharynx ina single direaction between the gill lamella. blood flows in the capillaries fo gill- lamella ina direaction oppsite to the flow of water over the lamellar surfaces. this greatly helps in the gaseous exchange across the lamellar membrane between the capillary blood and the flowing water. |
