During our science classes we have been learning about the Human heart and what it does to our body. Something I learnt was that there are 2 kinds of blood called oxygenated blood and De-oxygenated. Oxygenated blood carries oxygen and De-oxygenated blood doesn't carry oxygen.I also learn't that the main job for the plasma is to carry all the nutrients and proteins to the places where the body needs it.The funniest part of this experiment was cutting up the heart because it was so slippery and you could just see the 4 chambers and stuff like that.The chamber are 4 sections of the heart called right atrium and left atrium and also has right ventricle and left ventricle.Next year I am looking forward to looking a more hearts and learning more things.
