Describe the function of each structure. human whale cat bat bird crocodile

Humans have five vital organs that are essential for survival. These are the brain, heart, kidneys, liver and lungs. The human brain is the body's control center, receiving and sending signals to other organs, through the nervous system and through secreted hormones, (WHALES) Structure and function in whale ears ; Whales have adaptions for rapid deep diving and long submersion broad-bore Eustachian tubes,  no pinnae, And no air-feed external cannals that impact sound reception. In odontocetes, two soft tissue channels conduct sound to the ear. (Cats) The caudal verterbrae form the tail, used by the cat as an counterbalance to the body during quick movements. Unlike human arms, cat forelimbs are attached to the shoulder by free-floating clavicle bones, Which allows them to pass their body through any space into which they can fit their heads (BATS) A bat has much more flexible wing structure. It is very much like an human arm and hand, Except it has a thin membrane of skin (called the patagium) Extending between the "hand" And the body, and between each finger bone. Bats can the wing like a hand, essentially "swimming" through the air. (BIRDS) Bird anatomy, or the phsysiologicial structure of birds' bodies shows many unique adaptations, mostly aiding flight. Birds have a light skeletal system and light but powerful musculature,  which along with circulatory and respiratory systems capable of very high metabolic rates and oxygen supply, which permits the bird to fly.(CROCODILES) All crocodiles have a relatively long snout, or muzzle , Which varies considerably in shape and proportion Species are identified principally by the proportions of the snout, by the bony structures on the dorsal, or upper surface of the snout. And by the number and the arrangement of the scales.. I really hope this helps you! <3 sincerely talia.
