34
Q

List the full journey of a blood cell through the body

A

Drops Oxy blood off through a capillary, travels in veins to heart. Enters the superior or inferior venacava into the right atrium than the right ventricle, then the pulinarmy valve and artery send it to the lungs where it collects oxygen, it re-enters the heart through the pulmonary vein and enter the left atrium then left ventricle. Finally it leaves through the aorta and uses arterys to travel around the body
