HORMONAL COORDINATION IN HUMANS
ENDOCRINE SYSTEM
Pituitary Gland: the 'master gland' situated at the base of the brain.
Thyroid Gland: produces thyroxine
Adrenal Gland: produces adrenaline
Pancreas: produces insulin
Ovaries: produces oestrogen
Testes: produces testosterone
CONTROL OF BLOOD GLUCOSE CONCERNTRATION
DIABETES
TYPE 1: insulin injection - insufficient insulin produced by the pancreas
TYPE 2: blood cells do not respond to insulin - exercise regime - carbohydrate controlled diet - obesity is a risk factor
CONTROLLED BY THE PANCREAS
TOO HIGH
panceas secretes insulin. this triggers cells to take in glucose from the blood. the glucose is then converted into glycogen in the liver and muscles to reduce blood glucose concerntration
TOO LOW
pancreas produces glucagon. this triggers the muscles and liver to convert glycogen back into glucose. the glucose is then released into the bloodstream to increase the blood glucose concerntration
THE KIDNEYS
blood undergoes filtration to remove waste products and small soluble molecules from the blood
DISEASE
transplant
dialysis
blood is draw into a machine, flows next to the dialysis fluid and is separated by a membrane
DISADVANTAGES: time consuming, restricted diet, cannot be used indefinitely
ADVANTAGES: reduced urea, blood glucose same level, water and iron balance regulated
WATER BALANCE
loss of water
lungs during exhalation
sweat through the skin
