Blood pressure is the lowest in the legs. This is because it's at the most bottom of the circulatory system and farthest from the heart. As a result, the blood vessels in this area are the most dilated.
oxygenated blood through aorta.
The systemic circulation is the part of the circulatory system that carries oxygenated blood away from the heart to the body and returns deoxygenated blood back to the heart. In contrast, the pulmonary circulation is the part of the circulatory system that carries deoxygenated blood from the heart to the lungs for oxygenation and returns oxygenated blood back to the heart.
The left part...the left auricle & left ventricle
For the most part, arteries carry oxygenated blood and veins carry de-oxygenated blood. This is opposite in the pulmonary veins and arteries because they are going to and from the lungs to get oxygen.
The pulmonary arteries carry oxygen poor blood to the lungs.
Oxygenated blood is revived from the lungs through the pulmonary veins, which carry it to the left atrium of the heart. From there, the blood moves into the left ventricle, which pumps it out through the aorta to supply the body with oxygen. This process is part of the pulmonary circulation, where blood is oxygenated in the lungs and then returned to the heart for distribution.
The left ventricle is the part of the heart that pumps oxygenated blood to the different body parts. It receives oxygen-rich blood from the lungs and then contracts to send this blood out to the rest of the body through the aorta.
The Aorta carries the oxygenated blood away from the heart to all part of the body including the heart itself apart from the lungs.
The arteries carry oxygenated blood away from the heart to to the rest of the body.
The systemic artery, that leaves from the left ventricle.
the upper and lower part upper part- recives unoxygnated blood and release the oxygenated blood to the whole body system. lower part- or pumping station it recive the unoxygnated blood and the lower part will make it oxygenated blood.
The Atria and Ventricles are parts of the heart not the blood. The Atria is the upper chambers of the heart and the Ventricles are the lower chambers of the heart.
