Question

Describe the physiology of a frog in a pool at a highly elevated level using all biological systems (ex; respiratory.. etc)

Answer 1

Frogs uses skin, lungs and mouth(lining) for the respiratory purpose. When frog is present in pool or any other water bodies, their respiration occurs through skin, their skin contain large number of blood vessels, which helps them in respiration. Frog have lungs, take air through nostrils, they lack diaphram. Their throat get enlarged during the intake of air, then it is passed to the lungs, then the CO2 is eliminated through the mouth. While comming to the circulatory system, frog have 3 chambered heart. They have single ventricle and two atria. Left atrium contain oxygen carrying blood, which is carried to the brain with the help of arteries. Veins carry deoxygenated blood to the atrium. Ventricle contraction helps the blood to reach each and every part of its body. The main excretory system of frog is kidney, which mainly focused to take the nitrogen waste present in the blood. Nephrostome in kidney take the extra water and hormones, and other metabolic waste for removal purpose. Didestive system of frog contain mouth, phyarynx, oesophagus, stomach, small, large intestine and cloaca. From mouth the food reaches to stomach through oesophagus, from there several enzymes helps in the digestion(partial digestion). Complete digestion takesplace in small intestine, the nutrients absorbed into blood vessels and the waste is thrown out through cloaca.
