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.

 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)

 Carry lymphocytes, phagocytes and antibodies to sites of
infection to fight pathogens.

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.
