Stop trying to cheat on your homework I am going to tell Mr. Andrade
blood that is being pump from the heart to the lungs is oxygen.
Carbon dioxide is at high levels and oxygen at low levels in blood that is being pumped from the heart to the lungs.
it is pumped out of the lungs
Blood is pumped out of heart. It comes back to the heart. This circle goes on.
systematic
The amount of blood never changes, the frequency increases, like heart rate.
blood is pumped around your body by your heart, that's why you hear your heart beating because it us pumping the blood around your body :)
it is pumped to the heart first then to the lungs
The blood absorbs oxygen from the lungs - enabling it to be transported throughout the body.
The blood is pumped out of the heart, when it is oxygenated, through the left atrium and left ventricle into the aorta.
The left venricular chamber of the heart is responsible for pumping the blood throughout the body
