1. INTERNAL TRANSPORT IN MAMMALS

2.  Supplies all cells with the nutrients (eg. Glucose, mineral ions, amino acids), water and oxygen they require. INTERNAL TRANSPORT IN MAMMALS

3.  Supplies all cells with the nutrients (eg. Glucose, mineral ions, amino acids), water and oxygen they require.  Removes waste products from cell processes – eg. Carbon dioxide from respiration, urea from protein in the diet.  INTERNAL TRANSPORT IN MAMMALS

Carbon dioxide from respiration, urea from protein in the diet.  Removes heat energy from cellular respiration  Transports hormones from source to target organs (eg. The pituitary gland produces follicle-stimulating hormones which is transported to the ovaries where it controls the production of eggs) INTERNAL TRANSPORT IN MAMMALS

9.  Circulatory loops of mammals are totally separate.  No mixing of oxygenated and de-oxygenated blood occurs – this supports the high metabolic rate demanded by the active lifestyle of this group. IN MAMMALS
