Which region in the large intestine absorbs fluids and salts that remain after intestinal digestion?

A. Increased afterload: Increased afterload, the resistance the heart must overcome to eject blood, typically reduces stroke volume because the heart has to work harder to push blood against higher pressure.

B. Decreased heart contractility: This would reduce stroke volume, as the heart would be less effective at pumping blood.

C. Increased preload: Preload refers to the volume of blood in the ventricles at the end of diastole. An increased preload stretches the heart muscle, which typically leads to a stronger contraction and higher stroke volume.

D. Decreased blood pressure: While low blood pressure may reduce afterload, it doesn't directly increase stroke volume unless other factors are at play.

A. It is the air in the lungs after maximal inhalation: Total lung capacity (TLC) refers to the total amount of air the lungs can hold after maximum inhalation.

B. It is the quantity of air that a person can move into or out of the lungs: This defines vital capacity, not total lung capacity.

C. It is the amount of air that remains in the lungs after a normal tidal expiration: This describes functional residual capacity, not TLC.

D. It is the maximum volume of air that can be exhaled from the lungs after maximum inhalation: This is the definition of vital capacity (VC), not total lung capacity.
