Study Notes
Blood Circulation and Heart Structure
- Atria: Receiving chambers of the heart.
- Right Atrium: Receives deoxygenated blood from the body via superior and inferior vena cava, pumps it to the right ventricle.
- Left Ventricle: Receives oxygenated blood from the left atrium and pumps it into the aorta, the body's largest artery.
Cardiac Muscle and Cycle
- Coronary Arteries: Supply blood to the heart muscle, branching from the aorta.
- Diastole: The relaxation phase of the cardiac cycle, allowing the heart chambers to fill with blood.
- P Wave in ECG: Represents atrial activity, typically the first wave seen in an electrocardiogram.
Blood Vessels and Circulation
- Pulmonary Artery: Only blood vessel not part of systemic circulation; carries deoxygenated blood to the lungs.
- Veins: Blood vessels that return blood to the heart, aided by skeletal muscle movement and one-way valves.
- Three "H" Shaped Veins: Median cubital vein, cephalic vein, and basilic vein, commonly used for venipuncture.
Blood Composition and Disorders
- Eosinophils: White blood cells identifiable by bright reddish-orange granules when stained.
- Arteriosclerosis: Condition characterized by thickening, hardening, and loss of elasticity in artery walls.
- Embolus: A circulating mass in the blood that can be a blood clot or other undissolved material.
Blood Tests and Diagnostics
- Lactate Dehydrogenase (LD): Enzyme used in diagnosing heart disorders.
- Fibrin Degeneration Products (FDP): Test for vascular system disorders.
- Complete Blood Count (CBC): A diagnostic blood test providing information on various blood components.
Blood Components and Functions
- Plasma: The fluid portion of the blood, which contains clotting factors like fibrinogen.
- Serum: Clear or pale yellow fluid obtained after blood coagulation, devoid of clotting factors.
- Leukocytes: White blood cells that exit the bloodstream to perform immune functions.
Hemostasis and Injury Response
- Hemostasis: The process of stopping bleeding post-injury while maintaining overall blood flow.
- Platelet Plug Formation: Initial response in minor injuries, aided by applied pressure to seal the site.
Miscellaneous Facts
- Blood Type: Inherited traits determined by the presence or absence of antigens on red blood cells.
- Whole Blood: Blood in its original state, used for various laboratory tests.
- Prothrombin Time (PT): A test assessing blood coagulation time and efficiency.
