- What have we been learning about?
We have been learning about the Circulatory System and the different parts that make up our whole Circulatory System.
- Why are we dissecting a heart?
We directed a heart so we can see what the parts of the heart actually look like up-close and to understand how our hearts work more clearly while looking at it in real life.
- What are the parts of the heart? Did you see them?
The parts of the heart are:
Arteries - takes blood away from the heart.
Atrium - entryways where blood enters from each side of the heart, from the veins.
Valves - one-way gates, it only lets blood move in one direction. Helpful especially when pushing against gravity.
Heart Strings - Strong fibres that hold the valves in place.
Septum - separates the left and right side of the heart.
Veins - takes blood back to the heart.
Ventricles - V-shaped cavities which push the blood into arteries to take away from the heart.
Muscled walls - strong muscles to help squeeze and push the blood around the body. the left side of the heart has more muscles.
I, unfortunately, didn't get to dissect a heart because I wasn't at school at the time that they did dissect the hearts. I was really sad that I couldn't get the chance to dissect and look at a heart up-close because I really wanted to learn more about our hearts while also having the chance to the dissect one.
