Study Notes
Blood Components
- Plasma: The liquid part of blood that transports cells, nutrients, and waste.
- Erythrocyte: Commonly known as red blood cells; responsible for oxygen transport.
- Leukocyte: Also known as white blood cells; crucial for immune response.
- Platelet: Cell fragments involved in blood clotting processes.
Blood Pressure and Conditions
- Hypertension: Refers to consistently high blood pressure, monitored for health risks.
Circulatory Pathways
- Pulmonary Circuit: Network of vessels transporting deoxygenated blood to the lungs for oxygenation and back to the heart.
- Systemic Circuit: Pathway that carries oxygenated blood from the heart to the body and returns deoxygenated blood back.
Vascular Components
- Artery: Thick, muscular vessels carrying blood away from the heart.
- Arteriole: Smaller branches of arteries that lead to capillaries.
- Capillary: Tiny blood vessels with walls one cell thick, facilitating gas and nutrient exchange.
- Venule: Small vessels that collect blood from capillaries and lead to veins.
- Vein: Vessels that carry deoxygenated blood back towards the heart.
Vascular Functions
- Vasodilation: The process of smooth muscle relaxation in blood vessels, leading to increased blood flow.
- Vasoconstriction: The narrowing of blood vessels, reducing blood flow and increasing blood pressure.
Immune Response
- Antibody: Proteins produced by the immune system in response to foreign substances (antigens).
Heart Functionality
- Valves: Structures in the heart and veins that prevent the backward flow of blood.
- Pulse: The rhythmic pressure wave felt in arteries, corresponding to heartbeats; can be detected near the skin's surface.
Lymphatic System
- Lymphatic System: Network providing drainage and transport of lymph; plays a key role in immune responses.
