11. Who works the hardest?
The hardest working chamber in the heart is the left Ventricle.
She pumps blood to the entire body, so has thicker walls and is slightly bigger than the right ventricle.
The right ventricle has less work to do. She only pumps blood into the lungs. Hence, she has thinner walls and is slightly smaller than her sister, the left ventricle.

18. Blood accounts for 7% of the human body weight, with an average density of approximately kg/m3, which is very close to pure water’s density of 1000 kg/m3.
The average adult has a blood volume of roughly 5 liters (1.3 gallons) which is composed of plasma and several kinds of cells.
These cells, which are also called corpuscles of FORMED ELEMENTS, consists of the following:
Erythrocytes (red blood cells, RBCs)
Leukocytes (white blood cells)
Thrombocytes (platelets)
By volume, the red blood cells constitute about 45% of whole blood, and plasma about 54.3% and white cells about 0.7%

20. Blood Pressure usually refers to the arterial pressure of the systemic circulation.
During each heartbeat, blood pressure varies between a maximum (systolic) and a minimum (diastolic) pressure.
The blood pressure in the circulation is principally due to the pumping action of the heart.
Differences in mean blood pressure are responsible for blood flow from one location to another in the circulation.
The rate of mean blood flow depends on the resistance to flow presented by the blood vessels.
Mean blood pressure decreases as the circulating blood moves away from the heart through arteries and capillaries due to viscous losses of energy.

21. Mean blood pressure drops over the whole circulation, although most of the fall occurs along the small arteries and arterioles.
Gravity affects blood pressure via hydrostatic forces (e.g.,) during standing) and valves in veins, breathing, and pumping from contraction of skeletal muscles also influence blood pressure in veins.
