Cardiovascular and circulatory system
Hi,
I've got a test coming up in a week on the cardiovascular and circulatory system and I'd like some help because I'm stuck :confused:
Now my teacher (whom I cannot understand) was talking on and on about two parts of the heart, the left and the right, one of them (I think the right part) contains blood which contains mostly CO2 while the other contains mostly O2. One side pumps blood to the brain while the other pumps blood to the lungs etc. etc.
Anyway if someone could please explain the whole system and process simply I would really appreciate it.
Thanks,
