1) Pulmonary Circulation:This is the process where
deoxygenated blood is carried away from
the right ventricle of the hearth while oxygenated blood is returned to the

4) Physical exertion:It the expenditure of energy expended during physical
activity.
5) Vasoconstriction:It can be defined as the narrowing of the blood vessels which
result into contraction of the muscular wall of the vessels most especially
large arteries and small arterioles.
6) Vasodilation: This is when blood vessel is widening and result in
relaxation of smooth muscle cell within the vessel walls.
