Exocrine Glands:
Exocrine glands are the glands which do not pour their secretions directly into blood (like endocrine glands) but into a duct. These are the glands with ducts and the effect of their secretions is not generalized on all tissues of the body but specialized.
Example:
i) Salivary Glands
ii) Exocrine Pancreas
iii) Lacrimal Gland
iv) Bile Producing Cells of Liver
v) Secretory Cells of Stomach and Intestine
Exocrine Pancreas:
Pancreas secret pancreatic juice which contains a large number of digestive enzymes. Pancreatic juice goes to the intestine thorough a pancreatic duct and performs the function of digestion inside the intestine.
Mammary Glands:
Mammary glands are also exocrine glands which secret milk or colostrum. Milk is collected by a series of ducts and secreted outside the body.
Salivary Glands:
Salivary glands are present inside the jaw. These secret saliva which comes to the mouth (oral cavity) through salivary duct. Saliva is responsible for lubrication of food and early digestion of starch.
Lacrimal Gland:
Lacrimal is the gland which is present in the eye. Its secretion is the lachrymal secretion in the form of tears. Lachrymal secretion washes the eye and the lysozyme enzyme present in this secretion kill bacteria to protect eye.
Bile Producing Cells Of Liver:
The liver produces bile then it is stored in the gall bladder until need to digest fatty foods.
Secretory Cells Of Stomach And Intestine:
Secretory cells of stomach secrete gastric juice which is poured into the stomach. Gastric juice contains enzyme like pepsin which digest proteins. Similarly secretory cells of intestine secrete intestinal juice which contains many digestive enzymes.
Exocrine Glands And Their Secretions:
i) Lachrymal Gland: Tears
ii) Sweat Gland: Sweat
iii) Salivary Gland: Saliva
iv) Mammary Glands: Milk
v) Liver: Bile
vi) Sebaceous Gland: Sebum
