The left ventricle pumps blood to the systemic loop.
Blood returning from the body systemic circulation first enters which chamber of the heart?
From the left ventricle.
Left Ventricle, because it pumps blood to the systemic circuit whereas the right ventricle pumps blood to the lungs.
left ventricle
The left ventricle is the thickest and most powerful chamber of the heart. It has to pump blood further (to the body) than the right ventricle (to the lungs).
No; he was in the gas chamber with his friend and the other victims. The officer running the chamber refused to open it, even at the commandant's command, because the chamber was not yet cleared of deadly gas. It is a stunning, powerful and almost surreal ending.
Left ventricle has the strongest muscles. This ventricle has to pump blood to entire body parts. The blood pressure in the systemic aorta is about 120/80 mm of mercury. This has to be maintained by this chamber. The right ventricle has to pump blood to the lungs only. The systolic blood pressure here is about 25 mm of mercury, much less as compared to systemic blood pressure. When you actually see the muscles of the heart of cadaver, you get the idea very clearly and without further questioning.
In the pulmonary circulation, deoxygenated blood leaves the right section of the heart through the pulmonary artery, enters the lungs and oxygenated blood comes through the pulmonary veins. The blood then moves to the left atrium of the heart.
Diastole is when a given chamber of the heart is relaxing. There is atrial diastole and ventricular diastole. Most of the time when talking about diastole we are referring to the ventricular because that is when we measure the diastolic (low) pressure in your systemic arteries, usually the brachial artery.
The left lower chamber of the heart (also called left ventricle) is responsible of the nutrition of the entire organism (the systemic circulation), so it has to have the strongest heartbeat so that the blood can flow through all the tissues.
Two atria are more efficient than a single one because the organism can separate the deoxygenated circulation from the oxygenated circulation. This improves the overall oxygenation level of systemic blood circulation, which is more efficient.
