Right side pumps..
Deoxygenated blood from body to lungs
1 of 10
Left pumps..
Oxygenated blood from lungs to body for cellular respiration
2 of 10
4 chambers...
left atrium, left ventricle, right atrium, right ventricle
3 of 10
Why is the atrium thinner than the ventrcile?
Ventricles have to pump blood futher so need to be stronger
4 of 10
What is between the atria and ventricles?
Atrioventricular valves- stop back flow of blood- open when there's high pressure benhind them, forced closed when there's high pressure in front
5 of 10
Aorta..
Left ventricle, oxygenated blood to body AWAY FROM HEART
6 of 10
Pulmonary viens
Left atrium, oxygenated blood from lungs TO HEART
7 of 10
Pulmonary artey
Right ventricle- deoxygenated blood to lungs AWAY FROM HEART
8 of 10
Vena cava
Right atrium-deoxygenated blood from lungs TO HEART
9 of 10
Adaptions..
Left ventricle thicker than right, pumps blood to whole body, ventricles thicker than atrium, pump blood futher, AV and semilunar valves, stop backflow of blood,
