dissection





Pig heart dissection





yesterday in biology we did a pig heart disection and learned about the purposes and reasons of all the veins and how each part works. 
atriums-entry ways where blood enters each side of the heart from the veins
arteries-keeps blood away from the heart
veins-take blood back to the heart
ventricles-v shaped cavities which pushes the blood into arteries to take away from the heart
muscled walls-strong to help squeeze and push the blood around the body
septum-seperates left and right side of the heart
heart strings-strong fibres that hold the valves in place
valves-one way gates. let blood only move in one direction.

refelection: 
it was yuck but funny to play with and when ibrahim cried about it, but i geuss it was fine and good to learn about.
