The protein component of CD4 that helps stabilize the overall structure of the protein.

A type of antibody that is found in the highest concentration in the plasma.

A type of antibody that is found in bodily fluids like saliva, tears, and breast milk.

A type of inflammation that happens in the upper layer of skin (epidermis). It causes fluid build-up and spaces between skin cells, leading to swelling and itchiness.

Chief cells are located in the stomach and secrete pepsinogen, the inactive precursor to pepsin, a digestive enzyme that breaks down proteins.

Goblet cells are found in the lining of the small intestine and secrete mucus, which lubricates the passage of food and protects the intestinal wall from damage.

Parietal cells are found in the stomach and secrete hydrochloric acid (HCl), which helps to kill bacteria and activate pepsinogen, the inactive precursor to pepsin.

Lipids, or fats, are absorbed into the lymphatic system through lacteals, specialized lymphatic capillaries found in the villi of the small intestine.

Cholecystokinin (CCK) is a hormone that triggers the contraction of the gallbladder. It's released in response to the presence of fats in the duodenum.

Saliva is a slightly alkaline fluid produced by salivary glands in the mouth. It aids in digestion by lubricating food, dissolving food particles, and starting carbohydrate breakdown.

Gastrin is a hormone produced by the stomach that stimulates the release of gastric acid and pepsinogen.

Secretin is a hormone released by the duodenum in response to acidic chyme entering from the stomach. It stimulates the pancreas to release bicarbonate, which neutralizes the acidic chyme.

GIP (Glucose-dependent insulinotropic polypeptide) is a hormone released by the duodenum and jejunum in response to glucose and fat. It inhibits gastric acid secretion and stimulates insulin release.
