Final answer:
The Left Ventricle pumps oxygenated blood into the Aorta. This is part of the heart's role in circulating blood throughout the body in a system of one-way flow regulated by heart valves.
Step-by-step explanation:
The anatomic structure that pumps oxygenated blood into the Aorta is the Left Ventricle.
The human heart is divided into four chambers: two atria on the top and two ventricles on the bottom. The left ventricle receives oxygen-rich blood from the left atrium and pumps it into the aorta, which then delivers it throughout the body. The entire sequence of blood flow is controlled by various heart valves to ensure unidirectional flow and prevent backflow.
To put some structures in order according to blood flow from the heart to the body and back:
- Aorta
- Arteries
- Capillaries
- Venules
- Veins
