What is the term associated with the lungs in the context of the heart structure?

Study Notes
- The heart is a vital area of the body, with the acronym VA representing it.
- Blood flows from the rest of the body through the vena cava into the right atrium.
- From the right atrium, blood flows into the right ventricle, then gets pumped out through the pulmonary artery to the lungs.
- From the lungs, blood is transported through the pulmonary veins to the left atrium.
- From the left atrium, blood flows into the left ventricle, then gets pumped out to the aorta to the rest of the body.
- The heart has four main chambers: right and left atrium, and right and left ventricle.
- Arteries always take blood away from the heart, while veins always take blood to the heart.
- The term "pulmonary" is associated with the lungs.
- The exercise to memorize the heart structure involves creating arrows to show the flow of blood from one structure to another.
- The four main chambers of the heart are: right atrium, right ventricle, left atrium, and left ventricle.
- The heart has valves to prevent backflow of blood: pulmonary valves, aortic valve, tricuspid valve, and mitral valve.
Test your knowledge of the heart's anatomy and how blood flows through its chambers. Learn about the different valves, arteries, and veins that play a crucial role in the process. Understand the path blood takes from the body to the lungs and back again.
