INTERNAL TRANSPORT IN MAMMALS

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

INTERNAL TRANSPORT IN MAMMALS 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.

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)

IN MAMMALS Circulatory loops of mammals are totally separate.

IN MAMMALS 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.

The four-chambered heart, consisting of 2 atria and 2 ventricles; the right side pumps blood to the lungs and the left side pumps blood to the rest of the body.

THE HUMAN HEART Stick in handout and now we are going to the library Google ‘interactive heart anatomy’ http: //depts. washington. edu/simplant/heartsmarts. htm Is the best one!
