Study Notes

Sheep Heart Anatomy

Left Atrium: Receives oxygenated blood from the lungs via the pulmonary veins.
Left Ventricle: Pumps oxygenated blood to the entire body through the aorta; has a thick muscular wall.
Right Ventricle: Pumps deoxygenated blood to the lungs for oxygenation; thinner wall compared to the left ventricle.
Right Atrium: Receives deoxygenated blood from the body via the superior and inferior vena cavae.
Trabeculae Carnae: Ridges of cardiac muscle within the ventricles that support the ventricular walls.
Papillary Muscles: Muscles that contract to tense the chordae tendineae; prevent backflow of blood into the atria during ventricular contraction.
Pectinate Muscles: Prominent muscular ridges found in the anterior wall of the right atrium and the auricle; increase contractile strength.
Tricuspid Valve: Located between the right atrium and right ventricle; prevents backflow of blood during ventricular contraction.
Bicuspid Valve (Mitral Valve): Situated between the left atrium and left ventricle; regulates blood flow from atrium to ventricle.
Semilunar Aortic Valve: Located at the entrance of the aorta; prevents blood from flowing back into the left ventricle.
Pulmonary Semilunar Valve: Controls blood flow from the right ventricle into the pulmonary trunk; prevents backflow into the ventricle.
Chordae Tendineae: White fibrous cords that connect the papillary muscles to the AV valves; crucial for valve functionality.
Cardiac Muscle Tissue: Specialized muscle tissue found only in the heart; enables strong and rhythmic contractions.
Superior Vena Cava: Large vein that carries deoxygenated blood from the upper body to the right atrium.
Pulmonary Trunk: Artery that carries deoxygenated blood from the right ventricle to the lungs for oxygenation.
Aorta: Major artery that carries oxygenated blood from the left ventricle to the body; the largest artery in the body.
