Flying … Webb1 jan. 2009 · Insect gas exchange occurs in a series of steps. Oxygen molecules first enter the insect via the spiracle, then proceed down the branching tracheae to the tracheoles. The terminal tips of the tracheoles are sometimes fluid-filled, so at this point gas transport may occur in a liquid medium rather than air.
WebbC) Instead of flowing to the capillaries, blood travels alveoli to exchange gases. D) Blood flow ceases altogether since gases cannot be exchanged while diving. A. When you … WebbIn most animals, gas exchange occurs in three phases. What are they? Breathing—inhalation of oxygen and exhalation of carbon dioxide. Transport of gases—oxygen and carbon dioxide must be transported to and from the tissues of the body. Gas exchange with tissues of the body—oxygen and carbon dioxide must be …
WebbRelaxation of abdominal muscles. Neither (1) nor (2) Both (1) and (2) Pick out the statement that is wrong with respect to insects. Abdominal muscles do not take part in respiration. When abdominal muscles relax, the air is drawn in through spiracles and tracheoles. Contracting abdominal muscles drive the air out through the spiracles.
