Study Notes
Sheep Heart Anatomy Overview
- Brachiocephalic Artery: Major vessel branching from the aorta, supplying blood to the head and upper limbs.
- Superior Vena Cava: Large vein collecting deoxygenated blood from the upper body, drains into the right atrium.
- Right Atrium: Chamber receiving deoxygenated blood from the superior and inferior vena cavae and pumps it into the right ventricle.
- Right Ventricle: Receives blood from the right atrium; pumps deoxygenated blood to the lungs via the pulmonary trunk.
- Apex of the Heart: The pointed end of the heart, located on the left side, important for heart orientation and function assessments.
- Left Ventricle: Chamber responsible for pumping oxygenated blood to the body through the aorta; muscular and thicker than the right ventricle.
- Left Atrium: Receives oxygenated blood from the lungs via pulmonary veins; pumps blood into the left ventricle.
- Pulmonary Trunk: Major vessel carrying deoxygenated blood from the right ventricle to the lungs for oxygenation.
- Aorta: The largest artery in the body, distributing oxygenated blood to all parts of the body; arises from the left ventricle.
- Tricuspid Valve: Valve located between the right atrium and right ventricle, preventing backflow of blood into the atrium during contraction.
- Myocardium: The muscular tissue of the heart, responsible for the heart's contractions and overall functionality.
- Interventricular Septum: The muscular wall separating the left and right ventricles, crucial for maintaining circulatory efficiency.
- Trabeculae Carneae: Irregular muscular columns in the heart ventricles, aiding in contraction and structural support.
- Chordae Tendineae: Fibrous cords connecting the papillary muscles to the tricuspid and bicuspid valves, preventing valve prolapse.
- Bicuspid Valve (Mitral Valve): Valve between the left atrium and left ventricle; ensures proper blood flow direction within the heart.
- Aortic Semilunar Valve: Valve located at the exit of the left ventricle; controls blood flow into the aorta and prevents backflow.
