Heart Dissection

1. The atria is much smaller and more flappy than the ventricle. The ventricles are more muscular than the atria because the ventricles are required to pump out blood whereas the atrias are only responsible for collecting blood.
2. I noticed the differences between the veins and arteries that were entering and leaving the heart but putting my finger through them and seeing where they were going and where they came from. The arteries were also thicker than the veins.
3. I found the semi lunar valves and the AV valves. Both kind of valves are very strong. The semi lunar valves are more like pockets and the AV valves are connected to the chordae tendinae. Their purpose is to stop blood flow to go backwards.
4. The texture of the heart surprised me because I expected it to be most smooth.

How do you get parasites in your heart?

A lot of parasite infections concerning the heart are diagnosed in developed countries because of worldwide travel, HIV/AIDs and organ transplants. Certain parasites lay eggs which makes it worse. Heart failure can occur when dealing with parasite infections, the heart will pump blood inadequately, causing reduced blood flow, congestion of blood in the veins and lungs.

What does it mean for your lung to collapse and how to avoid it?

A collapsed lung is when air gets between the lung and the chest wall and when this happens the lung cannot will up with air to take a breath. You can prevent having a collapsed lung by not smoking, that is the key way for prevention of an collapsed lung.

1. An example of an experience where I felt successful in class would be when we made our digestive shirts and I was able to fit everything in it so perfectly.

2. I would say that something I tend to get off focus and chat around. But when someone is talking in a class discussion, I am respectful and I listen quietly.

3. Yes I frequently work in a group, mainly the people I sit with which would be: Robin, Baneet, Abbas and Prince. It chances the way I work because I typically like to discuss more than write stuff down. I feel like I learn better in discussions.

4. My goal in Biology is to learn how to write tests without being extremely nervous. Another goal is to complete all my assignments to the best of my ability. This will help me better my grade.

Because Biology is cool. :-)

First blogster post, waddap waddap Robin, Prince, Abbas and Ms Phillips?!
