Human Body

A tendon is a fibrous connective tissue which attaches muscle to bone.

The main function of sweating is to control body temperature. As the water in the sweat evaporates, the surface of the skin cools. An additional function of sweat is to help with gripping, by slightly moistening the palms.

Blood and lymph are types of connective tissues.

Gerontology, the study of the aging process, is devoted to the understanding and control of all factors contributing to the finitude of individual life.

Skin is composed of epithelial cells, and is therefore not an example of connective tissue. The major types of connective tissue include bone, adipose, blood, and cartilage.

Epidermis varies in thickness throughout the body depending mainly on frictional forces and is thickest on the palms of the hands and soles of the feet, and thinnest in the face (eyelids) and genitalia.

Antigen is present in red blood cells.

Appetite is triggered by environmental cues such as the smell or taste of food. Appealing foods can stimulate appetite even when hunger is absent.

The taste receptors are located in epiglottis, upper esophagus and tip of the tongue.

The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.

Pepsin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen. Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach.

Gastrin is a hormone produced by the stomach, which stimulates the release of gastric acid.

Most absorption of nutrients occurs in the small intestine.

Hepato-Pancreas is the largest digestive gland.

Enamel of teeth is the hardest part of our body.
