DRINKS water but absorbs it through the skin.Frog also go in hibernation (winter sleep) and aestivation (summer sleep). Frog are cold-blooded (their body temperature varies with the temperature).The frog body is divided into two parts- HEAD and trunk.Explanation-The respiratory passage includes the olfactory chambers, buccopharyngeal cavity, glottis, LARYNX, trachea, bronchial tubes, and lungs.Behind the tongue, and before the esophagus there is a slit-like opening. This slit opening is the glottis.Glottis is the tube LEADING to the lungs.Glottis help with breaths and vocalizes.Arytenoid cartilage is one pair, pyramid shape hyaline cartilage.Thereby in the frog, the glottis is controlled by the muscles of the arytenoid cartilage. The digestive system consists of the alimentary canal and digestive glands.The alimentary canal is short because FROGS are carnivores and hence the length of the intestine is reduced.The mouth opens into the buccal cavity that leads to the esophagus through the pharynx.The esophagus is a short tube that opens into the stomach which in turn continues as the intestine, rectum, and finally opens outside by the cloaca.The liver secretes bile that is stored in the gall bladder.The pancreas, a digestive gland produces pancreatic juice containing digestive enzymes.Food is captured by the bilobed tongue.Digestion of food takes place by the action of HCl and gastric juices secreted from the walls of the stomach.
