Animals including Humans - Keywords

The head is a crucial part of an animal's anatomy, containing the brain and sensory organs such as the eyes, nose, and mouth. It is the region where one experiences sensations like pain, illustrated by the discomfort caused by loud construction noise. The body, on the other hand, refers to the entire physical structure of an animal, which can experience sensations such as the aches felt after completing a marathon. Eyes, vital for vision, can vary in number across species, with insects often having more than two, and can express emotions like surprise. The ears are essential for hearing, capable of detecting sounds even from a distance.

The mouth serves as the entry point for food and the exit for exhaled gases, housing the tongue, which is the organ responsible for taste. Teeth within the mouth are instrumental in the digestive process, breaking down food into smaller pieces, and come in various forms to suit different dietary needs. Animals also have tails, which can be used for a range of purposes including balance, communication, and swatting insects. Legs are another key feature, adapted for movement and sometimes defense, as illustrated by the injury of a celebrated racehorse. Wings, claws, fins, scales, feathers, fur, beaks, paws, hooves, and arms are other anatomical features that serve a multitude of functions, from flight and movement to protection and food acquisition, each adapted to the lifestyles and environments of different animals.
