A gland is a group of cells or a “secreting organ” that excretes a chemical substance. This substance can take the form of hormones, sweat, saliva, mucus, or acids (i.e. HCl acid in gastric glands). Glands are tasked with helping create the substance that they then secrete for further use or total elimination from the body. The image shows the diff...
Glands are sectioned into two groups on the basis of their function. Endocrine glands excrete chemicals, such as hormones, through the basal lamina of cells that travel through the blood stream. Examples of endocrine glands are the thyroid glands and pituitary glands which play important roles in preserving the homeostatic balance of the body. But ...
A gland that we are all, perhaps, painfully aware of is the sweat gland. Whether we sense them during a class speech or after a nice hour of exercise, we know that our sweat glands are close to the epidermis of the skin and secrete beads of moisture. There are two types of sweat glands: eccrine and apocrine. Eccrine glands are distributed throughou...
