Decrease
in Oxygen in blood causes heart rate to increase initially in

order
to maintain Oxygen transport

Amount
of water in blood plasma decreases after about a week

Decreases

Blood
can carry greater quantity of Oxygen

Prolonged
hypoxia stimulates bone marrow to produce more red

After
a week, heart rate normalizes but stroke volume (volume pumped
|
|
by
left ventricle) decreases, leading to net drop in cardiac oxygen
