both ventricles contract simultaneously.

the left ventricle ejects a larger volume of blood with each systole than the right ventricle.

cardiac output increases with increased heart rate.

stroke volume increases with increased venous return.

allows excess fluid filtered by the capillaries to be returned back to the blood.

consists of a network of vessels that have numerous one-way valves along their length.

helps destroy and remove microorganisms and other foreign material from the body.

All of the above are correct.

equal to that of the systemic circulation.

less than that of the systemic circulation because it contains less blood than the systemic circulation.

greater than that of the systemic circulation because it is above the level of the heart whereas the systemic circulation is below the level of the heart.

less than that of the systemic circulation because it covers a much shorter distance than the systemic circulation.

Large proteins would leave the blood and be actively transported across the capillary wall and into the tissue

The net filtration of water out through the capillary wall would remain unchanged

The net filtration of water out through the capillary wall would decrease

Large proteins would leave the tissues and be actively transported across the capillary wall and into the blood

the resistance to blood flow through the blood vessels would increase.

the total blood volume would not change but there would be more red blood cells per millilitre of blood.

the viscosity of the blood would be decreased.

the red blood cells would become swollen due to the increased haemoglobin content within them.
