5.3 Hormonal Coordination in Humans
Reproduction
Secondary sexual characteristics at puberty
Oestrogen: stimulates ovulation
Testosterone: sperm production
Menstrual cycle
Oestrogen and progesterone: maintains uterine lining
HT: oestrogen stimulates the release of LH
FSH: maturation of an egg in the ovary
LH: stimulates release of an egg
FSH stimulates the release of oestrogen from a mature egg
IVF
FSH + LH given to stimulate maturation of eggs which are collected and fertilised
Embryos are then injected into mothers uterus
Disadvantages
Risk of multiple births
Low success rate
Stress
Contraception
Surgical sterilisation
Abstaining from sex around ovulation
Barrier
Injection/implant
Oral contraception
Blood glucose
Controlled by the pancreas
Too high
Stored in liver and muscles as glycogen
Too low
Pancreas secretes glucagon so glycogen is converted to glucose and released
Pancreas releases insulin --> glucose moved back into cells
Diabetes
Type 1
Insulin injections
Insufficient insulin is produced by the pancreas
Type 2
Body cells do not respond to insulin
Exercise regime
Obesity is a risk factor
Carbohydrate controlled diet
