Based on the detailed examination of the anatomical diagram, here is the complete labeling for all 14 structures indicated in the figure:
Left Side Labels (Top to Bottom):
1.
Aorta: The large, arching artery that carries oxygenated blood from the left ventricle to the systemic circulation.
2.
Superior Vena Cava: The large vein that returns deoxygenated blood from the upper half of the body to the right atrium.
3.
Right Atrium: The upper right chamber of the heart that receives deoxygenated blood from the venae cavae.
4.
Tricuspid Valve: The valve located between the right atrium and the right ventricle, which prevents backflow of blood into the atrium during ventricular contraction.
5.
Right Ventricle: The lower right chamber of the heart that pumps deoxygenated blood to the lungs via the pulmonary artery.
6.
Inferior Vena Cava: The large vein that returns deoxygenated blood from the lower half of the body to the right atrium.
Right Side Labels (Top to Bottom):
1.
Pulmonary Artery: The large artery that carries deoxygenated blood from the right ventricle to the lungs for oxygenation.
2.
Pulmonary Veins: The vessels that carry oxygenated blood from the lungs back to the left atrium.
3.
Left Atrium: The upper left chamber of the heart that receives oxygenated blood from the pulmonary veins.
4.
Mitral (Bicuspid) Valve: The valve located between the left atrium and the left ventricle, which prevents backflow of blood into the atrium during ventricular contraction.
5.
Left Ventricle: The lower left chamber of the heart, with the thickest muscular wall, which pumps oxygenated blood to the systemic circulation via the aorta.
6.
Interventricular Septum: The muscular wall that separates the left and right ventricles.
7.
Chordae Tendineae: The fibrous cords that connect the papillary muscles to the tricuspid and mitral valves, preventing them from prolapsing into the atria during ventricular contraction.
8.
Papillary Muscles: Muscular projections within the ventricles that anchor the chordae tendineae.
