secretion Add to list Share. A secretion is a substance made and released by a living thing , like when your skin sweats. ... For example, the secretions of some frogs are a type of poison. Some secretions stay within an animal, like the bile secreted by our livers. Saliva is another secretion.
What is an secretion?
Secretion, in biology, production and release of a useful substance by a gland or cell ; also, the substance produced. In addition to the enzymes and hormones that facilitate and regulate complex biochemical processes, body tissues also secrete a variety of substances that provide lubrication and moisture.
What are some examples of secretion?
A substance, such as saliva, mucus, tears, bile, or a hormone , that is secreted. The process of secreting a substance from a cell or gland. A substance, such as saliva, mucus, tears, bile, or a hormone, that is secreted.
What is a secretion cite five example?
secretion means a substance secereted or released by an organism. eg- bogy glands secreting substances like thyroid gland secrete thyroxine. 2)saliva secreted in mouth.
What is secretion in a cell?
Summary. Secretion is a fundamental cellular process involving the regulated release of intracellular products from cells . Physiological functions such as neurotransmission, or the release of hormones and digestive enzymes, are all governed by cell secretion.
What is the major organ of secretion?
Kidneys . The paired kidneys are often considered the main organs of excretion. The primary function of the kidneys is the elimination of excess water and wastes from the bloodstream by the production of the liquid waste known as urine.
What is the difference between secretion and production?
As verbs the difference between produce and secrete
is that produce is to yield, make or manufacture ; to generate while secrete is to extract a substance from blood, sap, or similar to produce and emit waste for excretion or for the fulfilling of a physiological function or secrete can be to conceal.
What is secretion give 2 examples?
A secretion is a substance made and released by a living thing, like when your skin sweats. ... For example, the secretions of some frogs are a type of poison. Some secretions stay within an animal, like the bile secreted by our livers. Saliva is another secretion.
Is saliva a secretion?
Saliva gland acinar cells are chloride and sodium secreting, and the isotonic fluid produced is rendered hypotonic by salivary gland duct cells as it flows to the mouth. The major proteins present in saliva are secreted by salivary glands, creating viscoelasticity and enabling the coating of oral surfaces with saliva.
What is the nature of secretion?
Secretion involves the release of proteins and other macromolecules by a cell . In eukaryotic cells, proteins synthesised at the ER are transported to the Golgi, where they are packaged into vesicles, transported to the plasma membrane and released via exocytosis.
What is the difference between excretion and secretion?
Both these processes involve the movement of materials in the body. But the difference between excretion and secretion is that excretion is the removal of waste from the body , whereas secretion involves the movement of materials within the body.
What do secretory cells do?
Secretory cells and tissues are concerned with the accumulation of metabolism by products which are not used as reserve substances . Most secretory cells are specialized cells derived from elements belonging to other tissues, mainly epidermis or parenchymatous tissues.
What substances are secreted by cells?
The cells in these glands secrete specific chemicals called hormones . Hormones circulate around the body via the blood stream and modulate cellular or organ functions by binding with receptors in the target cells. Hormones that stimulate and control the activity of other endocrine glands are called trophic hormones.
What is secretion process?
Secretion is an energy-consuming process such that increased blood flow, supplying oxygen to the tissue , is required during active secretion and factors that diminish pancreatic blood flow reduce pancreatic secretion. From: Encyclopedia of Gastroenterology, 2004.
What is the process of protein secretion?
Proteins destined to be secreted move through the secretory pathway in the following order: rough ER → ER-to-Golgi transport vesicles → Golgi cisternae → secretory or transport vesicles → cell surface (exocytosis) (see Figure 17-13). Small transport vesicles bud off from the ER and fuse to form the cis-Golgi reticulum.
Which cell organelle is responsible for secretion?
Explanation: Golgi complex or the Golgi apparatus is one of the most important celluar organelles. This complex organelle is mainly responsible for the secretion of the protien,hormones and enzymes,in order to accomplish different biological celluar activities.
