What are Exocrine cells in human body.
Exocrine cells are specialized cells that produce and release substances through ducts onto body surfaces or into body cavities (like the digestive tract or skin). In contrast to endocrine cells, they do not release their products directly into the bloodstream. Role of Exocrine Cells in the Body Exocrine cells are present in organs such as the pancreas, salivary glands, sweat glands, and sebaceous glands. Their functions include: (a) Digestion: Pancreatic exocrine cells secrete enzymes (amylase, lipase, proteases) into the small intestine to break down food. (b) Lubrication: Salivary glands produce saliva to moisten food and aid swallowing. (c) Temperature regulation: Sweat glands release sweat to cool the body. (d) Skin protection: Sebaceous glands secrete sebum to keep skin soft and protected from microbes. Production Process of Exocrine Secretions Exocrine cells follow a structured proce...
