    Study Notes

    Blood Clotting

    • First step in clotting: The coagulation cascade begins with the activation of Factor XII (Hageman factor).
    • Antihemophilic factor: Factor VIII is known as the Antihemophilic factor
    • Conversion of prothrombin: Prothrombin converts to thrombin during blood clotting.
    • Fibrinogen to fibrin: Thrombin facilitates the conversion of fibrinogen to fibrin during clot formation.

    Heart Anatomy

    • Septum function: The septum divides the heart into left and right sides, preventing the mixing of oxygenated and deoxygenated blood.
    • Tricuspid valve: Located between the right atrium and right ventricle.
    • Endocardium: Lines the inner chambers of the heart, providing a smooth surface for blood flow.

    Blood Flow

    • Deoxygenated blood flow: After leaving the right ventricle, deoxygenated blood flows to the lungs through the pulmonary artery.
    • Oxygenated blood vessel: The pulmonary vein carries oxygenated blood from the lungs back to the heart.
    • Pulmonary artery blood: Deoxygenated blood flows through the pulmonary artery
    • Aorta: The aorta is the main artery carrying oxygenated blood from the heart to the rest of the body.
