Study Notes
Blood Components and Functions
- Erythrocytes are anuclear, biconcave disks essential for oxygen transport from lungs to tissues.
- Plasma contains fibrinogen while serum does not; this distinction is crucial in coagulation processes.
- Blood typing (A, B, AB, O) is defined by antigens present on red blood cells.
Heart Anatomy and Physiology
- The right atrium is the heart chamber that receives systemic blood.
- The myocardium is the heart's thick muscular layer responsible for contractions.
- The bicuspid valve, also known as the mitral valve, regulates blood flow between the left atrium and ventricle.
Cardiac Electrical Activity
- P waves on an ECG indicate atrial contractions, signaling heartbeats.
- The AV node initiates the heartbeat, coordinating the heart's electrical activity.
Blood Pressure and Circulation
- Systolic pressure is measured upon the first heart sounds during blood pressure assessment.
- Diastolic pressure reflects arterial pressure during ventricular relaxation.
Circulatory Pathways
- The pulmonary system carries deoxygenated blood to the lungs for oxygenation.
- The correct sequence of blood flow through vessels starts with capillaries, followed by venules, and then veins.
Coagulation and Hemostasis
- Following blood vessel injury, the order of events is platelet aggregation, vasoconstriction, and fibrin clot formation.
- Hemostatic plug formation occurs after platelet aggregation during clotting.
Veins, Arteries, and Blood Composition
- The longest vein is the great saphenous vein; the longest artery is the aorta.
- Veins carry blood towards the heart, while arteries typically transport blood away from the heart.
Blood Vessel Structure
- The lumen is the internal space of blood vessels where blood flows.
- The outer layer of blood vessels is called tunica adventitia; it provides structural support.
- Veins are characterized by having valves, a feature that arteries do not possess.
Other Key Concepts
- Congestive heart failure causes fluid buildup in the lungs, indicating heart dysfunction.
- Tachycardia refers to an increased heart rate, a condition that may signal various health issues.
- Embolus describes a blood clot that moves through the bloodstream, potentially causing obstructions.
- Thrombocytes (platelets) are formed elements linked to megakaryocytes, playing a vital role in clotting processes.
- Prothrombin time testing evaluates the hemostatic process, important for diagnosing clotting disorders.
