In science we have been learning about dissecting hearts and lungs. This photo shows me holding a heart that me and my group cut open to have a look at how it works.
The heart is made of four chambers you have the right atrium, left atrium, right vertical and left vertical. the right atrium pulls the blood back to heart and then pumps it down to the right vertical and then that pumps it up and around to the left atrium and the down to the bottom left vertical and then that pumps it out in to the body which also oxygenates the blood
the most fun thing i did in science was dissecting the heart and looking at how it works
wow
