Give a brief description on how to identify 1st, 2nd and 3rd degree burns.

Name the 3 layers of heart tissue from outer to inner
Epicardium, myocardium, endocardium
Describe the process of gas exchange in the alveoli.
Gasses (CO2 and O2) diffuse down their concentration gradient from an area of higher concentration to an area of lower concentration. O2 diffuses into the blood stream via alveoli and co2 diffuses into the lungs.
