Answer to Question 1

C
The wall of the left ventricle is threefold thicker than that of the right because the left ventricle propels blood to most vessels of the body. The right ventricle moves blood only through the blood vessels of the lungs and then into the left atrium.

Answer to Question 2

D
With multifocal atrial tachycardia, the atrial and ventricular rhythms are usually irregular as the pacemaker site shifts from the SA node to ectopic atrial locations or AV junction.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
