1. How are respiratory systems different in different animal 2. Differentiate between inhalation and exhalation. 3. How does the air that we breathe in reach the lungs? 4. How is carbon dioxide removed from the body? 5. Explain respiration in insects.
Answers
Answer:
Question no 1
They have a large capillary network, the gas exchange surfaces are thin and moist; constant renewal of oxygen-rich fluid (air or water) order to provide oxygen and remove carbon dioxide.
Question no 2
Inhalation is a part of breathing where the air is taken into the lungs by creating negative pressure by the contraction of respiratory muscles and diaphragm. Exhalation is a part of breathing where the air is drawn out of the lungs by the relaxation of respiratory muscles.
Question no 3
When you inhale through your nose or mouth, air travels down the pharynx (back of the throat), passes through your larynx (voice box) and into your trachea (windpipe). Your trachea is divided into 2 air passages called bronchial tubes. One bronchial tube leads to the left lung, the other to the right lung.
Question no 4
The lungs and respiratory system allow oxygen in the air to be taken into the body, while also letting the body get rid of carbon dioxide in the air breathed out.
Question no 5
They have an air-based respiration, as gas exchanges are carried out with gases in the air. Unlike most of the air-breathing vertebrates , the insects (invertebrate animals) do not breather using lungs.
