State the role of the following in the process of respiration :
1) Epiglottis
2) Cartilegunous ribs
3) Alveoli
Answers
Answer:
number 2 is the answer understand
Answer:
1) Epiglottis
The epiglottis is a leaf-shaped flap of cartilage located behind the tongue, at the top of the larynx, or voice box. The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled.
2) Cartilegunous ribs
Costal cartilage. The costal cartilage are segments of cartilage that connect the sternum to the ribs and help to extend the ribs into a forward motion. This cartilage also contributes to elasticity within the walls of the thorax, allowing the chest to expand during respiration.
3) Alveoli
Alveoli are an important part of the respiratory system whose function it is to exchange oxygen and carbon dioxide molecules to and from the bloodstream. These tiny, balloon-shaped air sacs sit at the very end of the respiratory tree and are arranged in clusters throughout the lungs
