Tasks of Blood

Post by risingstar5 » Sun Apr 23, 2006 6:23 pm

just after injecting the blood in the left ventricle with 14C, it would be detected performing the task of
- picking up O2 from the systemic capillaries of the body
- dropping off O2 in the systemic capillaries of the body
- picking up O2 in the capillaries of the lungs
- dropping off CO2 in the capillaries of the lungs
- dropping off O2 in the capillaries of the lungs

Please help....i'm confused... :?

and what would blood in the right ventricle do???
Never let the odds keep you from pursuing what you know in your heart you were meant to do. <3

Well, here's the short summary of how the heart works and then you can figure out your answer from that:

Blood enters the right atrium from two major veins: the Superior Vena Cava which brings blood from the upper body and the Inferior Vena Cava that brings blood from the lower body. This blood is low in oxygen and therefore bluish in color. The blood then goes to the right ventricle and from there goes to the lungs where they CO2 is released and O2 taken into the blood.

The blood then returns to the heart into the left atrium. From here it is pumped into the left ventricle and then out through the aorta. From here it takes all the branches of arteries to supply O2 to the cells all over the body.

blood in the right side of the heart is deoxygenated blood. it gets pumped to the lungs where oxygen diffuses into the blood and then the blood gets pumped to the left side of the heart.
