Heart Dissection

Hello. Today in biology class we dissected a heart. We have been learning about the heart and how it works for the past few weeks. We did the dissecting to see all its parts and how all of the parts work. Before we did the dissecting I think I'm going to see all of the parts and lots of blood. 

 Right Side: 

1. From the superior vena cava, cut down the right side from the atrium to the ventricle. 

2. Identify the right atrium, ventricle, and valve. 

3. Follow from the ventricle up through the artery.

 Left Side: 

1. From the Pulmonary vein, cut down the left side from the atrium to the ventricle. 

2. Identify the left atrium, ventricle, and valves. 

3. Follow from the ventricle up through the artery. 

 I saw the way where the blood enters from the vein which is called an atrium. The valve's job is to make the blood move in one direction. The septum separates the left and right sides of the heart. The muscle walls help to push the blood around the body and the left side of the heart has more muscle than the right side. The heartstrings help to hold the valves in place. I think the dissection was successful but I accidentally cut myself while dissecting the heart. Overall I really enjoy it.
