Study Notes
Aorta
- Main artery of the body, carrying oxygenated blood from the heart to the rest of the body.
- Distributes blood to smaller arteries supplying limbs and organs, excluding the lungs.
Superior & Inferior Vena Cava
- Two large veins transporting deoxygenated blood to the right atrium.
- Superior vena cava gathers blood from the brain and upper limbs.
- Inferior vena cava, the largest vein, drains blood from the trunk and lower limbs.
Right and Left Pulmonary Arteries
- Branch from the pulmonary trunk, directing deoxygenated blood to corresponding lungs.
Function of Pulmonary Arteries
- Carry deoxygenated blood from the right ventricle to the lungs for oxygenation.
- Distinct from bronchial arteries, which supply nutrients to lung tissue.
Right and Left Pulmonary Veins
- Responsible for returning oxygenated blood from the lungs to the left atrium.
- Unique among veins for carrying oxygenated blood instead of deoxygenated.
Function of Pulmonary Arteries and Veins
- Pulmonary arteries transport deoxygenated blood to lungs; pulmonary veins bring oxygenated blood back to the heart.
Pulmonary Trunk
- Major vessel originating from the right ventricle, bifurcating into the right and left pulmonary arteries.
Function of the Pulmonary Trunk
- Serves as a conduit for deoxygenated blood from the heart to the lungs for purification and oxygenation.
Right and Left Atria
- Blood enters heart via atria; deoxygenated blood enters the right atrium from vena cavas.
- Right atrium pumps blood into the pulmonary circuit.
Right and Left Ventricles
- Right ventricle pumps deoxygenated blood to lungs through the pulmonary artery.
- Left ventricle, the thickest chamber, pumps oxygenated blood to the body.
Function of Right and Left Ventricles
- Right ventricle sends blood to the lungs; left ventricle supplies body tissues with oxygenated blood.
Septum
- Divides heart into right and left sides, consisting of atrial (between atria) and ventricular (between ventricles) septa.
Tricuspid Valve
- Located between the right atrium and right ventricle; prevents backflow of blood into the right atrium.
Bicuspid (Mitral) Valve
- Ensures unidirectional blood flow; improper closure can lead to backflow into atria from ventricles.
Chordae Tendineae
- Attach to papillary muscles in ventricles, aiding in the function of atrioventricular valves to prevent backflow.
