why is there five times as much cardiac muscle in the left ventricle as there is in the right ventricle.

Ah a good question.
The blood that flows through the heart goes through four stages. It flows from the Vena Cava (All veins eventually feed into the it as it flows back to the heart) into the right atrium.
The right atrium feeds the blood into the right ventricle, which pumps blood to the lungs to get recharged with oxygen.
The fresh new oxygenated blood flows into the left atrium and then to the left ventricle (via a valve, which prevents the heart from pumping blood backwards)
The left ventricle musters up all of its strength and with a mighty shove, pushes the blood out to the rest of the body. (Well not really mighty, but you get the idea)
Since the right ventricle only has to pump the blood through the lungs, a much shorter trip, it doesn't have to be as big as the left ventricle. Hence, the reason for the difference in muscle tissue.

The left side of the brain does more work than the right so the heart needs to send more blood and oxygen there.

Because blood is pumped thru the heart from the left side

coz the left ventrical exerts more pressure for the blood flow.
