Topics

• The frog’s gut runs mouth, oesophagus, stomach, small intestine, rectum and opens into the cloaca.
• The liver is three-lobed and red-brown; bile from the gall bladder enters the duodenum.
• The frog heart has three chambers: two atria and one ventricle, which mixes the blood a little.
• The right atrium receives blood from the body and the left atrium oxygen-rich blood from the lungs.
• Two kidneys lie against the back; ureters carry urine to the cloaca, which also receives the bladder.
• Male frogs have a pair of yellowish testes on the kidneys, with finger-like fat bodies beside them.
• The brain (forebrain, midbrain, hindbrain) runs on into the spinal cord, which sends nerves to the body.
• On land frogs breathe by the buccal cavity, lungs and skin; in water and in hibernation, through the skin alone.
