Secretion

The slowest moving, most important productions of the human body.

• The process of releasing and oozing chemicals from a cell or gland. Eukaryotic cells including human cells have a highly evolved process of secretion.
• Hormones are secreted.
• Hormonal messages are slower, the nerve is quicker.
• The parasympathetic system generally stimulates secretion while the sympathetic system generally acts in an inhibitory manner.
• Secretion and excretion are similar in that both involve the movement of materials. Secretion is often required to move a material to the place where it can be excreted.
• Both help to maintain homeostasis by controlling the amounts of materials that exist in certain places in the body.
• Secretions in humans, enzymes, hormones.
• Interesting facts.
• Secretion is very important in bacterial function and operation in their natural surrounding environment for adaption and survival.
• Insulin is cleaved from proinsulin in the secretary vesicles.
