Cat Dissection

This is our cat dissection. At first it was so gross cutting into the cat. After a while it stared to stink and i could no longer stand the smell. i learned a lot of parts of the cat. The cat has similar parts just like we do in the human body. The inside of the cat was easy to see the most hard ones were more in the neck and the legs and arms, but mostly what we needed to see were the muscles. the small intestines are so much bigger then the large ones. I would figure that the small ones would be the bigger one and the large intestine would be the small one. The heart was really small and was right next to the liver. at first i thought that the liver was the lungs and the lungs was the liver. So there different in size compared to the human body. IN the end i did learn a lot about the cat. As our final we had to remember the parts and show that we know where they were. I think i did okay I got most of them on the left side of the page but missed a couple on the right. So all in all i had fun with this dissection. GLAD THAT THERE ARE NO MORE DISSECTIONS!!!!!! :)

Swimming Lab

EKG LAB

A couple of weeks ago we did an EKG lab. EKG stands for

Electrocardiogram or is also known as an ECG.

Its fun how we can measure our own heart beat. In a a heart beat you have the PQRST. Each letter has its own meaning and placing of a heart beat.

As you can see here in this picture the the letters are places in different positions. The first letter is the P. Which is s the first wave of the electrocardiogram and represents the spread of electrical impulse through the atrial musculature. Next is the QRS wave represents the spread of the electrical impulse through the ventricular muscle (depolarization). The Q wave is the first downward position then the R wave is a upward position and the S wave is a negative reflection following the R wave. Then Last the T wave. The T wave represents the period of recovery for the ventricles (repolariztion).

I DID MY OWN EKG LAB RESULTS AS YOU CAN SEE MINE LOOKED DIFFERENT FROM WHAT YOU WOULD SEE IN A REGULAR ONE LIKE THE ONE ABOVE. MINE WAS MORE SPREAD OUT.

Virtual Lab on heart beats

We had just did a Virtual lab by listing to a virtual heart beat and deciding what kind of heart was it. What effects it had to it. The first one was a male heart beat. His name is Alex A. Aorta. He is a 30 year old male, and currently is having a heart problem. Alex came in complaining of syncope. The patient mentions that he has lost a sister earlier to heart disease and he is worried that heart disease runs in the family.

In the exam room I had to listen to his heart. It didn't sound like a regular heart beat. What a regular heart beat sounds is a Lub dub. His was nothing like that. As I was listening to the heart beat the heart sound indicates a Systolic Murmur.

The murmur occurs between the lub and the dub. This means that the problem may be narrowing of the outflow from the left ventricle to the aorta or leaking of the mitral valve. We then go to the echo room to visualize the heart movement. This is what it looked like.

In this picture it shows that the person has a dilated aorta This condition is known as aortic aneurysm. Aortic aneurysm is a potentially very dangerous condition so surgical invention may be necessary to replace the aorta with artificial prosthesis.

After that we took him in for an MRI. In the MRI it showed what was wrong with his heart. Its just with its aortic aneurysm and nothing else. As you can see the problem within the heart. 

Then next we start with his Pedigree. To see who else can be involved in getting what this man has or how does it run in the family.

In his family this trait is Dominant trait. So what this is telling us is that his father had it then it went to his sister and him then to his daughter and to his sister son. So it runs in the family. So the family is suffering from Marfans Syndrome.

That was all about the Virtual lab that we did. There are two more other patients but I just thought I'd show you one and show what a Virtual lab is all about.

Brain Dissection

This here is the brain Dissection. Me and my partner Desi dissected a brain. It felt really nasty. It smelled gross to. First we had to figure out a way to cut it so that we would be able to see all the parts of the brain. As you can see in the pictures we figured out a way to cut it so we can see the inside of the brain. On the outside of the brain we saw the cerebellum and some of the brain stem. On the inside of the brain you can see the inside if it. All the tubes that blood goes through. In one of the pictures that me and Desi took you see that we cut the brain apart and we put our brain together. We were basically just trying to find places of the brain on where everything was at. 
After we had our fun with the brain we decide just to mess with the brain and cut it a little more deeper. You can see in one of the pictures how we cut it. The brain looks really weird. Its crazy how on can look inside a persons head.

Sheep heart Dissection

These pictures are of a sheep and a pigs heart. As you can see the pigs heart is a lot bigger then the sheep's heart. Me and Desi had a sheep's heart. It was really tiny compared to the other hearts. On the outside of the heart it had a lot of white fat on top of it. We cut it right down the middle and got to see the inside of the heart. We saw the the Aorta the Vena Cava the ventricles the veins and the arteries. The inside of the heart is very thick. With this dissection we just had to look at it and locate some of the hearts        parts. Also we had to measure how long was some parts of the heart. On our measurements we were around 2 to 3 cm. Thats not very big, is it. Just imagine how big our heart is. I'm starting to like the anatomy of the heart. The heart for some reason is very interesting to me, but theres so many things that you have to know about the heart. Well still I had fun with the heart dissection. At least I know that I can handle stuff like this.

Checking Blood Pressure/Heart pressure

A couple days ago we played with stethoscope and blood pressure readings. I played doctor with Desi as she did the same with me. I couldn't get the old fashion way to work for me. I had a hard time getting air to pump through. I did hear her heart beat though.
i had to learn about a lub and a dub of the heart beat. we have two beats for the heart. The first beat is the lub and the second beat is the dub. So together the heart is Lub Dub.
At first even with the upgraded blood pressure monitor I couldn't get a reading on Desi heart and blood pressure. After a while I had to reach 160 just so it could get a reading.
For me I only had to get up to at least 120 and the monitor got my heart beat right away. Also at first it was hard to even get a heart beat but after a few tries we got it to work for us.

These are the tools we used to monitor or heart and blood pressure.
