Study Notes
Endocrine vs Exocrine Glands
- Exocrine glands release chemicals into ducts, such as sweat, tears, and digestive juices
- Endocrine glands release chemicals directly into the bloodstream, these chemicals are called hormones
- Examples of hormones include testosterone, estrogen, and insulin
Endocrine System Terminology
- Glands release products directly into the bloodstream
- Hormones are chemical messages carried around the body
- Target cells have specific receptors on their cell membrane which allow them to receive hormonal messages
Pituitary Gland
- It is known as the master gland because it controls other glands
- The pituitary gland releases Growth Hormone (GH) which is responsible for growth. Too little GH results in dwarfism, while too much results in gigantism.
- The pituitary gland also releases Antidiuretic Hormone (ADH), which stimulates the kidneys to retain water
Thyroid Gland
- The thyroid gland controls metabolism and energy in the body.
- It releases thyroxine (T4)
Adrenal Glands
- Adrenal glands are responsible for the fight, flight or freeze response
- Adrenaline increases heart rate and blood pressure, and supplies more oxygen to muscles and organs to allow for a quick response
Pancreas
- The pancreas is an endocrine and exocrine gland
- It releases enzymes and hormones
- The pancreas releases glucagon and insulin, which regulate blood sugar
Ovaries
- Ovaries produce progesterone and estrogen
- The ovaries are responsible for puberty and sexual maturity
Testes
- Testes produce testosterone.
- The testes are responsible for puberty and sexual maturity
Endocrine & Exocrine Glands
- Exocrine glands release chemicals into ducts, examples include sweat, tears and digestive juices
- Endocrine glands release chemicals into the bloodstream, they have no ducts and their chemicals are called hormones, examples include testosterone, estrogen and insulin
Endocrine System Terminology
- Glands: release products into the bloodstream directly
- Hormones: chemical messages carried around the body
- Target cells: specific cells that have appropriate receptors on their cell membrane
Pituitary Gland
- Also known as the master gland, because it controls the other glands
- Growth Hormone (GH) is responsible for growth, too little GH leads to dwarfism and too much GH leads to giantism
- Antidiuretic Hormone (ADH) stimulates kidneys to hold water
Thyroid Gland
- Controls metabolism and energy in the body
- Thyroxine (T4) is the hormone produced by the thyroid gland
Adrenal Glands
- Hormones made by the adrenal glands including adrenaline are responsible for fight, flight or freeze reactions
- Adrenaline increases heart rate and blood pressure, supplies more oxygen to the muscles and organs to help you respond quickly
Pancreas
- An endocrine and exocrine gland that makes enzymes and hormones
- Regulates blood sugar by means of the hormones glucagon and insulin
Ovaries
- Produces progesterone and estrogen
- Function: controls puberty and sexual maturity
Testes
- Produces testosterone
- Function: controls puberty and sexual maturity
