During exercise, the typical response of systolic blood pressure is to increase. This is because the heart pumps harder and faster to supply more oxygen and nutrients to the muscles.
Hypertension causes the left ventricular wall to thicken. This is followed by a dilatation of the left ventricle and a reduction in the amount of blood pumped from the heart.

Blood returning from pulmonary circulation returns to the right atrium via the pulmonary vein. Blood returning from the systemic circulation returns to the right atrium via the Vena Cava.
The left atrium is the chamber that receives oxygenated blood returning from the lungs.
Veins
The veins.
The natural biologic response to repeated myocardial ischemia (insufficient oxygen levels in heart muscle) is angiogenesis, the growth of new collateral blood vessels. http://www.cardiumthx.com/science-technology-overview.html
Blood returning from the body systemic circulation first enters which chamber of the heart?
arterioles
Carbon dioxide
A sudden reduction in blood flow is called ischemia. This can lead to tissue damage or even cell death if blood flow is not restored promptly.
