I like videos - saves me from reading! :-) Try this youtube video which explains it quite well:

What you need to remember:

Atria receive blood from the circulation (diastole)
Ventricles push blood out of the heart (systole)

Hope this helps a little.

That link was really good. I've had the same problem of the way the heart works just not sticking in my mind.

The exam you have tomorrow is it the edexcel paper? And does this website cover all the notes on the edexcel syllabus? Sorry its jus im new on here. Lol

hiya,

i am also sitting my exam and these tips might help...

~A before V - the blood enters the atrium before the ventricle (atrium at the top, ventricle at the bottom)

~ pulmonary vein is the only vein to carry oxygenated blood (from the lungs)

~ pulmonary artery is the only artery to carry deoxygenised blood away from the heart (to the lungs)

~ Arteries = away from heart veins = towards

~ in a diagram, the right side is on the left, and the left side is on the right (as if you are looking at someones chest)

there are a few more, but if you try to get those you should be ok. :) good luck.

Rosie
