21

65. Where is the left ventricle... when blood enters the left ventricle... is the blood low in oxygen or higher in oxygen?

Blood entering the left ventricle is high in oxygen, because it has just come from the left atrium which receives oxygen rich blood


73. BP- Blood

67. Where is valve and what is its function?

It separates the left atrium from the left ventricle. It's function is to prevent blood from flowing back into the atrium from the ventricle.
