Answers
Answer:
a.......In the second stage of swallowing, an important small flap of tissue called the epiglottis, folds over the voice box (larynx) at the entrance to the windpipe (trachea), preventing food from going down the wrong way........
b....The protein inside red blood cells (a) that carries oxygen to cells and carbon dioxide to the lungs is hemoglobin (.......
c...Diaphragm helps to "increase the volume" of chest cavity lengthwise.
The function of diaphragm is inhalation. ...
This increment the area in your chest gap, by which the lungs gets expand.
The "intercostal muscles" between your ribs also "help enlarge the chest area".........
d.....HAEMOGLOBIN......
e.....Combines with the oxygen in the lungs – Bronchioles. Protects the lungs from mechanical injuries – Ribs. Provides actual diffusion of respiratory gases in lungs – Air sacs/alveoli.........
f.....Alveoli present in the lungs produces actual diffusion of gases. Alveoli are the balloon like structures in the lungs where the diffusion of or say exchange of gases takes place........
