Human Endocrine System

• The human endocrine system is composed of glands that secrete different types of hormones into the bloodstream.
• The pituitary gland, also known as the 'master gland', is located at the base of the brain and produces FSH and LH.
• The pancreas produces insulin, which is a hormone that helps regulate the blood glucose level.
• The thyroid, located in the neck, produces thyroxine which is a hormone that helps control the metabolic rate and affects growth.
• The adrenal gland, located on top of both kidneys, produces adrenaline and cortisol.
• The ovaries in females produce oestrogen and progesterone.
• The testes in males produce testosterone.
• The blood carries the hormone around the body, and when it reaches a target cell/organ it produces an effect.
• Compared to the nervous system the effects of the hormones are slower but they act for longer.
