Study Notes
Cardiovascular Structures and Functions
- Aortic Arch: Major artery that curves over the heart, providing oxygenated blood to the body.
- Bicuspid Valve: Also known as the mitral valve, located between the left atrium and left ventricle; controls blood flow direction.
- Ventricular Contraction: During contraction, valve cusps are held closed by chordae tendineae, preventing backflow into the right atrium.
- Great Cardiac Vein: Returns deoxygenated blood from the heart muscle to the right atrium; often found near the coronary arteries.
Connective Tissue and Heart Structures
- Dense Irregular Connective Tissue: Provides structural support and strength to various heart structures, enabling them to withstand pressure changes.
- Left Auricle: A small, ear-shaped chamber on the left atrium, helping to increase capacity for blood reception.
- Pulmonary Veins: Vessels that carry oxygenated blood from the lungs to the left atrium of the heart.
- Superior Vena Cava: Large vein that carries deoxygenated blood from the upper body to the right atrium.
Arterial Structures
-
Three Branches of the Aortic Arch:
- Brachiocephalic Trunk: Supplies blood to the right arm and head.
- Left Common Carotid Artery: Supplies blood to the left side of the head and neck.
- Left Subclavian Artery: Supplies blood to the left arm.
- Ascending Aorta: The section of the aorta extending upward from the heart, supplying arterial blood to the body.
- Brachiocephalic Trunk: First major branch of the aortic arch, bifurcating into the right common carotid and right subclavian arteries.
Additional Cardiac Features
- Foramen Ovale: A fetal opening between the atria, allowing blood to bypass the non-functioning lungs; closes at birth.
- Marginal Artery: A vessel formed by anastomosis between the branches of the right and left coronary arteries, supplying the margin of the heart.
- Posterior Interventricular Artery: Supplies blood to the posterior walls of the ventricles; branches from the right coronary artery.
- Right Auricle: A pouch-like structure on the right atrium that increases its volume.
- Tricuspid Valve: Located between the right atrium and right ventricle; prevents backflow of blood into the atrium during ventricular contraction.
