1. Describe which features are most apparent on your heart.
Veins, Valves, and Apex
  1. A probe in either the superior or inferior vena cava penetrates the?
Right Atrium
  1. A probe in the pulmonary vein terminates which chamber?
Left Atrium
  1. A probe in the pulmonary arteries will penetrate which chamber?
Pulmonary trunk
  1. The right chambers of the heart pump what kind of blood?
Deoxygenated blood
  1. Describe the appearance of the valves.
Think and covered in chordate tendenae
  1. Describe the appearance of the papillary muscles.
It is very tough and strong, coloring varies. Covered in thick bands.
  1. Describe how the atrium appears and feels in your words.
It is thin and feels very soft.
  1. Is the myocardium of the atrium thicker or thinner than the ventricle? Explain why.
It is thinner, because it pumps blood only to the heart, not to the rest of the body.
  1. Name the 2 veins that empty into the right atrium.
Superior and Inferior Vena Cava.
  1. What is the wall that separates the 2 ventricles called?
Interventricular Septum
  1. What is the purpose of the pulmonary veins?
To transport oxygenated blood into the heart.
  1. What is the layer of the heart wall that covers the inside of the chambers? What does it look like?
The endocardium. Thin and has shiny covering.
  1. Describe the appearance and feel of the walls of the ventricles.
It is tough and groovy.
  1. How much thicker is your left ventricle from your right?
A lot thicker
  1. What causes a blocked artery in the heart AND what symptoms would indicate a need for bypass surgery?
A blocked artery is caused from plaque, which is a buildup of fat. The symptoms are chest pain or heart attack.
  1. Where doe they get the bypass vessels from in the body?
An artery may be detached from the chest wall and piece of the long vein from the leg
  1. What main vessel do they attach the bypass to?
They attach it to the coronary artery below the blocked area.

First we picked up the heart and looked at it's ventral side, we identified what each was. Then we cut the heart to open it and get a better view of i. We probed many things to see what they were and where they led to. Then we cut the ride side to see the right ventricle and the tricupsid valve. We identified it from the right side and left side to see each part of the heart. I liked being able to do this experiment hands on rather then just from a text book. It really allowed me to get a better idea where stuff was in the heart, what it looked like and what it felt like. We did not like the smell from the chemicals at all, that was the only thing really that we disliked. We learned the many things of the heart, when we put our probe into something we pushed through to see where it ended. I never knew the heart was so stuff, that was one of the things I really learned about. It was crazy to feel how hard the heart muscles truly are. If I were to change anything about this lab, I would say that we cover our noises, because that sometimes distracted me from being able to do things.
