Study Notes
Blood Vessels Overview
- Carotid Artery: Supplies blood to the brain and spinal cord.
- Tunica Intima: Innermost layer of blood vessels, comprised of endothelium and an elastic membrane.
- Edema: Condition characterized by the abnormal accumulation of interstitial fluid.
Blood Pressure Terms
- Systolic Pressure: Peak blood pressure measurement during heartbeats.
- Mean Arterial Pressure (MAP): Average blood pressure in a single valve, calculated by adding 1/3 of pulse pressure to the diastolic pressure.
- Diastolic Pressure: Minimum blood pressure at the end of ventricular relaxation.
Vascular Conditions and Structures
- Aneurysm: A bulge in the weakened wall of an artery.
- Anastomoses: Connections between small blood vessels that do not involve capillary beds.
- Plaque: Fatty masses of tissue that protrude into the lumen of blood vessels.
Vascular Processes
- Vasoconstriction: Occurs when arterioles constrict due to smooth muscle activity in the tunica media.
- Fenestrated Capillaries: These capillaries contain pores in the endothelial lining facilitating rapid exchange of water and solutes.
Hormonal Regulation
- Erythropoietin (EPO): Released by kidneys in response to low blood pressure or oxygen levels, stimulating red blood cell production.
- Antidiuretic Hormone: Secreted by the hypothalamus, it promotes water conservation at the kidneys.
Blood Circulation
- Blood Hydrostatic Pressure (BHP): Essential in determining the fluid movement across capillaries.
- Arterioles: Small arteries that deliver blood to capillary networks.
- Valves: Structures within veins that prevent backflow of blood.
- Superior Vena Cava: Vein that carries blood from above the heart to the right atrium.
- Venules: Thin-walled veins that collect blood from capillaries.
Blood Vessel Functionality
- Conducting Vessels: These vessels stretch their elastic walls to help maintain stable blood pressure as blood volume increases.
- Net Filtration Pressure (NFP): Calculated as the difference between net hydrostatic pressure and net osmotic pressure.
