the ventricles because it pumps blood
Left atrium
Left Ventricle
left ventricle as it pumps blood to all parts of the body..
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 left ventricle
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.
The heart of a lamprey looks similar to that of modern fish in a sense. It is a two chambered heart with a single atrium and a single ventricle. The atrium of the heart is proceeded by a sinus venosus, which isn't considered an actual chamber but rather pre-heart chamber. Then after the ventricle we have a conus arteriosus that again isn't considered to be a chamber of the heart but rather a post-heart chamber. The blood flow through the heart is a one way path like that of modern day fishes.
it is connected by an aorta
