Heart Attacks - Medical Science

Heart Attacks

In science we are learning about medical science just yesterday we dissected a lambs heart. Today we are now recapping what we have learnt about this muscle.

Here are some questions you might have that I will answer in this post.
What is a Heart Attack?, How do you know you're having one?, How can you prevent this?  And other facts about the heart.

A heart attack is when blood vessle that supply blood to the heart are blocked, preventing enough oxygen from getting to the heart, this can lead to symptoms such as, chest pains or you may feel pain from your chest move to your, arms, shoulders, neck, teeth, jaw, belly area or back. Exercising daily or several times a week and walking is a good form of excersice and prevents  heartattacks. It is important to talk to your doctor before starting an exercise routine.

Random Information about the heart.
One side of the heart is thicker than the other, this is because one side is used to pump blood throughout the body while the other just receives blood and does not need additional muscles.

To tell muscle and fat apart one is thin and pale while muscle is more thicker and red. 
Valves are a very important part of the heart. They work to keep blood moving in the correct direction. These are located in your veins.

As you can see in the image on the right, there is a large tube to the left side of the heart. That is Superior Vena Cava, this artery brings de-oxygenated  blood from the body to the heart.  The blood vessel next door closest to the top of the image is the Aorta, this artery pumps clean, oxygenated blood throughout the body reasoning why the muscle and walls around it to be thicker than the other half of the heart.

Pig Heart vs. Lamb Heart
What is the difference between pig🐖 and lamb🐑 hear?. Yesterday we dissected a lamb heart, though we thought we would be getting a pig heart. A pig heart would be more different than the lamb heart and more similar to ours. Both pig and human heart have more distinct tunnels and tubes. Lamb heart are smaller and harder to see details.

Animal Heart Facts
Did you know? Jellyfish, Sea Cucumber alnd Star-Fish have no hearts unlike the Octopus🐙 and Squid🦑 who have three hearts each. The Humming Birds heart can beat up to 1200 beats per minute while the Blue Whales heart is the slowest heart in the animal kingdom beating up to only six beats per minute.
