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.
