- Hormones
- Adrenaline
- Fight or flight response
- From adrenal glands
- Increases heart rate
- Boosts delivery of oxygen and glucose to brain & muscles (respire faster)
- Thyroxine
- Produced by thyroid gland
- Increases metabolic rate
- Controls growth / development of young animals
- Release stimulated by TSH
- Glucagon
- Blood glucose concentration too low = glucagon
- Stimulates conversion of glycogen to glucose
- Released by pancreas
- Insulin
- Blood glucose concentration too high = insulin
- Glucose moves from blood to liver/muscle cells
- Excess glucose -> glycogen
- Insulin
- Insulin
- Blood glucose concentration too high = insulin
- Glucose moves from blood to liver/muscle cells
- Excess glucose -> glycogen
- ADH (Anti-Diuretic Hormone)
- More water = less ADH from pituitary gland
- Higher blood concentration = more ADH
- Less ADH = less water reabsorbed by kidney = more urine
- Urea from liver, breakdown of proteins (contains nitrogen)
- Excess amino acids converted to ammonia, ammonia converted to urea
- Progesterone
- Progesterone inhibits FSH and LH
- LH (Luteinising Hormone)
- Stimulates release of egg from ovary (ovulation)
- FSH (Follicle Stimulating Hormone)
- FSH stimulates oestrogen / oestrogen inhibits FSH
- Oestrogen
- Oestrogen stimulates LH
- LH (Luteinising Hormone)
- Stimulates release of egg from ovary (ovulation)
- LH (Luteinising Hormone)
- Makes lining of uterus regenerate after menstruation
- Oestrogen stimulates LH
- Oestrogen
- Causes eggs to mature in ovaries
- FSH stimulates oestrogen / oestrogen inhibits FSH
- LH (Luteinising Hormone)
- Maintains lining of uterus in 2nd half of cycle
- Progesterone inhibits FSH and LH
- Oestrogen
- Oestrogen stimulates LH
- Makes lining of uterus regenerate after menstruation
- Oestrogen stimulates LH
- FSH (Follicle Stimulating Hormone)
- FSH stimulates oestrogen / oestrogen inhibits FSH
- Causes eggs to mature in ovaries
- FSH stimulates oestrogen / oestrogen inhibits FSH
- Adrenaline
