Study Notes
Sheep Heart Dissection Labels
- Left Subclavian Artery: Major artery supplying blood to the left arm and parts of the chest.
- Arch of Aorta: The curved portion of the aorta that gives rise to major arteries supplying the upper body.
- Pulmonary Trunk: The vessel carrying deoxygenated blood from the right ventricle to the lungs for oxygenation.
- Left Atrium: Chamber of the heart that receives oxygenated blood from the lungs via the pulmonary veins.
- Anterior Interventricular Sulcus: A groove marking the boundary between the left and right ventricles on the heart's surface.
- Left Ventricle: The heart's chamber responsible for pumping oxygenated blood to the body; has thick muscular walls.
- Apex: The pointed end of the heart, directed downward and to the left, where the heart's greatest pressure occurs.
- Right Ventricle: Chamber of the heart that pumps deoxygenated blood to the lungs through the pulmonary trunk.
- Right Atrium: Receives deoxygenated blood from the body via the superior and inferior vena cavae.
- Superior Vena Cava: Large vein that channels deoxygenated blood from the upper body to the right atrium.
- Right Brachiocephalic Trunk: Artery that branches into the right common carotid artery and right subclavian artery.
- Left Atria: Receives oxygenated blood from the pulmonary veins; important for circulation.
- Posterior Interventricular Sulcus: Groove at the back of the heart that indicates the division between the ventricles.
- Wall of Right Ventricle: Thinner than the left ventricle as it only needs to pump blood to the lungs.
- Intraventricular Septum: Thick wall separating the left and right ventricles, essential for maintaining blood flow.
- Papillary Muscle: Muscles within the ventricles that anchor heart valves using chordae tendineae to prevent backflow.
- Wall of Left Ventricle: Thick muscle layer necessary for pumping blood with high force to the body.
- Right Bicuspid Valve: Also known as the tricuspid valve, it prevents backflow from the right ventricle to the right atrium.
- Wall of Left Atrium: Thinner than ventricle walls, but still muscular enough to help push blood into the ventricle.
- Aortic Semilunar Valve: Valve preventing backflow from the aorta into the left ventricle post-contraction.
- Aorta: The main artery that carries oxygenated blood away from the heart to the body.
- Pulmonary Arteries: Vessels that carry deoxygenated blood from the right ventricle to the lungs for gas exchange.
