left ventricle as it pumps blood to all parts of the body..
The left ventricle, it works the hardest and needs the most muscle mass.
endocardium
The fox has a 4 chambered heart.
The left atrium is the chamber that receives oxygenated blood returning from the lungs.
atrium
Left Ventricle
the ventricles because it pumps blood
assuming you mean the heart it is the left ventricle becasue it is the part that pumps blood to the rest of the body
yes, it has to pump the blood through the aortic semilunar valve, then to the aorta and off to the body
heart
the hardest working horse is a appolosa. the hardest working muscle in your body is the heart. it pumps loads of blood through your body every second!
Because it has the pump the hardest since it is the final flow of blood in the heart.
Heart blood vessels is what collects blood and pumps it to the lower chamber. This is what keeps the heart in working function.
The left ventricle, it works the hardest and needs the most muscle mass.
it is connected by an aorta
An artificial heart is made from metal and plastic, and has a small pumping chamber lined by a special material that stops blood clots forming. An artificial heart that provides an extra ventricle to help pump blood around your body.
Because it pumps blood all around your body. In comparison the right ventricle only pumps deoxygenated blood a short way across to your lungs (think of where your heart is compared to your lungs, then consider how far away your little toe is!)
