2) To which parts of the body do the right and left sides of the heart pump blood?

3) Through which blood vessels does oxygen-rich blood return from the lungs to the heart?

4) Why is the wall of the left ventricle is thicker than that of the right ventricle?

5) Describe the path that oxygen-poor blood takes into and out of the heart.

6) Name the four valves in the heart. What is the purpose of these valves?

Answer 1

1. Cardiac muscle
2. right = lungs, left = everywhere else (musles, organs, brain, etc...)
3. pulmonary vein
4. it needs to pump harder so that it can generate enough force to pump blood throughout the body, the right side just pumps to the lungs so it doesn't need to pump as hard
5. it enters the heart thorugh the vena cava which feeds into the right atrium. It then passes through the tricuspid valve to the right ventricle. it leaves the heart through the pulmonary valve into the pulmonary artery
6. tricuspid valve = prevents blood from flowing back into the right atrium from the left atrium
pulmonary valve = prevents blood from flowing back into the right ventricle from the pulmonary artery
mitral valve = prevents blood from flowing back into the left atrium from the left ventricle
aortic valve = prevents blood from flowing back into the left ventricle from the aorta
7. the ventricular septum. this keeps deoxygenated blood from mixing with oxygenated blood so that tissues are getting an oxygen rich blood supply

Answer 2

Triple H, I find him a boring wrestler who needs to get out of the business, he doesnt have many moves either less than cena he only married stef for 12 titles, he needs to be a midcarder, he takes the title from more awesome wrestlers like edge or randy orton, he was better as a heel but i just dont like him all round as a heel or face, he is also rude to other wrestlers in the back and hates better wrestlers than him randy and edge, he loves vince and if he didnt do stef he would be a washed up nobody
