    Study Notes

    Blood Circulation and Structures

    • Aorta contains oxygenated blood, transporting it from the heart to the body.
    • Pulmonary artery is part of the pulmonary circuit, carrying deoxygenated blood to the lungs.
    • Aorta is involved in the systemic circuit, delivering oxygenated blood to body tissues.
    • Veins such as the inferior and superior vena cava carry deoxygenated blood to the right atrium.

    Blood Flow Pathway

    • Sequence of blood flow from the aorta: arteries, arterioles, capillaries, venules, veins.

    Blood Vessel Characteristics

    • Lumen refers to the interior space within a blood vessel.
    • Arteries possess the thickest tunica media for strength and elasticity.
    • Arteries transport blood away from the heart, while veins bring it back.
    • Capillaries have walls that are one cell layer thick, enabling efficient gas and solute exchange.

    Oxygen Content in Blood

    • Arteries are the only blood vessels that typically contain oxygenated blood.
    • Capillaries contain a mixture of oxygenated and deoxygenated blood due to their function in exchange.
    • Venous blood has the lowest oxygen concentration.

    Observation and Phlebotomy

    • Bright cherry red blood in an evacuated tube indicates arterial blood from a puncture in an artery.
    • Dark red blood suggests venous blood collected from a vein during venipuncture.

    Heart Chambers and Blood Return

    • Blood enters the right side of the heart via the superior vena cava.
    • Blood enters the left side through the pulmonary veins, bringing oxygenated blood from the lungs.

    Coagulation Factors

    • Thrombin is essential for converting fibrinogen into fibrin during clot formation.
    • Calcium is critical for coagulation processes both in vivo (within the body) and in vitro (outside the body).

    Components of Hemostasis

    • Hemostasis involves blood vessels, platelets, and coagulation factors for maintaining blood stability post-injury.
    • Fibrinogen is found in plasma but is absent in serum, indicating its role in coagulation.

    Plasma Composition

    • Normal plasma consists primarily of water, which forms the bulk of its content, with solutes like proteins and electrolytes dispersed throughout.
