William Bayliss and Ernest Starling discovered the neurotransmitter acetylcholine in 1902. This discovery was significant in understanding the role of chemical messengers in the nervous system and how they regulate physiological processes.
It is the hormone gastrin. It is secreted by stomach
The hormone secretin functions as a chemical messenger in the digestive system. It is released by the duodenum in response to the presence of acidic chyme, and it stimulates various organs like the pancreas to release bicarbonate to neutralize the acidity in the small intestine.
No, bile is not a hormone. Bile is a digestive fluid produced by the liver and stored in the gallbladder, which helps in the digestion and absorption of fats in the small intestine. Hormones are chemical messengers produced by glands that regulate various physiological processes in the body.
That is the stomach. It produces the hormone gastrin
SECRETIN
A target cell is a cell in the body that recognizes a hormone's chemical structure. It is a cell to which a hormone binds chemically.
The primary chemical affected by the renin-angiotensin-aldosterone system is angiotensin II. This hormone is involved in regulating blood pressure and electrolyte balance by causing vasoconstriction and stimulating the release of aldosterone from the adrenal glands.
Hormone receptors on cell membranes recognize a hormone's chemical structure in the endocrine system. When the hormone binds to the receptor, a cell changes its behavior.
A growth hormone is a chemical that has effects on plant growth
An antidiuretic hormone is a hormone secreted by the posterior pituitary gland.
