- Transport from lungs which is alveolus to all part of body/cells
- In the lung, oxygen combines with haemoglobin, Hb to form oxyhaemoglobin then pumped to tissue
- In tissue, oxyhaemoglobin supplied for cellular respiration
2) Transport of water to tissue
- to provide biochemical reactions
- 90% of water
3) Transport of carbon dioxide
4) Transport excretory waste products
- Deamination of excess amino acid occurs in liver to form urea
- From liver urea is transpoerted by blood to kidneys to be excreted
5)Transport of hormones
- Produces by the endocrine glands. For example: insulin and glucagon are carried by blood form pancreas to the liver
6) Transport of heat
- Regulate body temperature
7) Transport absorbd foor materials
- Soluble digested food, vitamins and mineral absorbed into the cappilaries of the villi in the small intestines. For examples: simple sugar (glucose), amino acid, vitamin B, ,mineral salts
- They are transported by hepatic portal vein from small intestines to liver then to heart
- Others food are absorbed into lacteals in villi. For examples: fatty acids, glycerol, vit A, D, E, K
