Draw a well labelled diagram of a heart
Unfortunately, as a text-based AI, I am unable to draw diagrams. However, I can provide a well-labelled description of a heart:
1. Aorta (Major Artery): The largest artery, responsible for carrying oxygenated blood from the heart to the body.
2. Superior Vena Cava (Major Vein): Collects deoxygenated blood from the upper part of the body and returns it to the right atrium.
3. Pulmonary Artery: Carries deoxygenated blood from the heart to the lungs for oxygenation.
4. Pulmonary Veins: Four veins (two from each lung) that carry oxygenated blood from the lungs to the left atrium.
5. Right Atrium: Receives deoxygenated blood from the body through the superior and inferior vena cava.
6. Right Ventricle: Sends deoxygenated blood to the lungs via the pulmonary artery for oxygenation.
7. Left Atrium: Receives oxygenated blood from the lungs through the pulmonary veins.
8. Left Ventricle: Sends oxygenated blood to the body through the aorta for distribution to various organs and tissues.
9. Septum: A thick muscular wall separating the right and left side of the heart to prevent the mixing of oxygenated and deoxygenated blood.
10. Tricuspid Valve: Located between the right atrium and right ventricle, it prevents the backflow of blood from the ventricle into the atrium.
11. Mitral/Bicuspid Valve: Located between the left atrium and left ventricle, it prevents the backflow of blood from the ventricle into the atrium.
12. Aortic Valve: Located between the left ventricle and the aorta, it prevents the backflow of blood from the aorta into the ventricle.
13. Pulmonary Valve: Located between the right ventricle and the pulmonary artery, it prevents the backflow of blood from the artery into the ventricle.
Please note that this is a simplified representation, and the heart has many more structures and blood vessels that contribute to its overall functioning.
