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.
