- B5
- Skeletons
- Humans have an internal skeleton made of cartilage and bone, both of which can repair itself
- The human skeleton starts as cartilage and becomes ossified (turned into bone) by the addition of calcium and phosphorus
- Ball and socket joints and synovial fluid
- Respiration
- Gaseous exchange takes place in alveoli
- Industrial, genetic and lifestyle choice factors cause lung diseases
- Methods of respitation limit fish and amphibians to their habitats
- CO2 at high levels is toxic in the blood
- Digestion
- Due to enzyme requirements, the stomach contents is acidic and the small intestine is alkiline
- Small digested food molecules are absorbed into the blood plasma
- Starch is broken down to maltose then to glucose
- Reproduction and Growth
- Hormones( Oestrogen, FSH LH and progesterone) control the menstrual cycle
- Foetal development can be checked by chromosome analysis
- Human growth hormone is produced in the pituatory gland
- Different parts of the foetus grow at different rates
- Skeletons
- The biceps and triceps muscles are antagonists in the arm

- Respiration
- Humans have closed double circulation systems, fish have closed single systems
- Heart rate is linked to activity
- Heart muscles contraction is controlled by cells called pacemakers (SAN and AVN
- A 'hole in the heart' is a hole between either two atria or two ventricles, Oxygenated blood is then mixed up with deoxygenated blood so the blood caries less oxygen
- Blood can be donated and transfused

- A heart transplant is the insertion of a new heart
- Transplants may cause rejection reactions to occut
- Blood and Circulation
- Negative feedback mechanisms control hormone production
