Answers
Answer:
Q).
A. Earthworms have no special respiratory organs. Gases are exchanged through the moist skin and capillaries, where the oxygen is picked up by the haemoglobin dissolved in the blood plasma and carbon dioxide is released.
B. Fish gills are organs that allow fish to breathe underwater. Most fish exchange gases like oxygen and carbon dioxide using gills that are protected under gill covers (operculum) on both sides of the pharynx (throat). Gills are tissues that are like short threads, protein structures called filaments.
C. Frog Respiration. The frog has three respiratory surfaces on its body that it uses to exchange gas with the surroundings: the skin, in the lungs and on the lining of the mouth. ... A frog may also breathe much like a human, by taking air in through their nostrils and down into their lungs.
D. The opening from the pharynx leading to the continuation of the respiratory passageway is the glottis. Midsagittal section of the head of a cow with nasal septum removed. The stippled area represents the pathway of air through the nasal cavity, pharynx, and trachea. The glottis is the opening to the trachea.
E. The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history.
