(a) Draw a neat diagram of the respiratory system and label the following parts:(540) Lungs, (ii) Trachea, (iii) Bronchus, (iv) Diaphragm(b) Name the respiratory pigment in buman beings and discuss its role.(c) Why is the rate of breathing in aquatic organisms faster than that in terrestrialรถrganisms? |
Answer» b)A respiratory pigmentisamolecule, such as hemoglobin inhumansand other vertebrates, that increases the oxygen-carrying capacity of the blood. The four most common invertebraterespiratory pigmentsare hemoglobin, hemocyanin, hemerythrin and chlorocruorin. c)Aquatic animalstake in the oxygen dissolved in water. The amount of dissolved oxygen in water is fairly low compared to the amount of oxygen in the air. Therefore,rate of breathing in aquatic organismsis muchfaster thaninterrestrial organisms.
