Puzzle 05: Vascular Disorders and Hemodynamics
Across
- 3. An antidiuretic hormone produced by the hypothalamus that induces profound vasoconstriction at high serum concentrations.
- 6. A chronic elevation of systemic arterial blood pressure that forces the heart to work harder and accelerates vascular remodeling.
- 8. The widening of blood vessels resulting from relaxation of smooth muscle cells within the vessel walls, dropping peripheral resistance.
- 9. An inadequate delivery of arterial blood to a tissue, depriving local structures of both oxygen and cellular metabolic nutrients.
- 10. Localized ischemic necrosis of a tissue zone resulting from complete occlusion of its local arterial or venous blood supply.
- 11. A progressive disease characterized by the accumulation of lipid plaques and chronic inflammatory cells within large arterial walls.
- 12. The narrowing of blood vessel lumens due to contraction of the vascular smooth muscle, increasing systemic afterload forces.
- 16. The formation or presence of a blood clot within a blood vessel, which can narrow or completely obstruct vascular flow paths.
- 17. The homeostatic mechanism that provides rapid negative feedback regulation of arterial blood pressure via heart rate and resistance adjustments.
- 19. A classification of shock characterized by persistent tissue hypoperfusion caused primary by failure of the heart's pumping action.
- 20. A form of distributive shock resulting from the sudden loss of autonomic sympathetic vasomotor tone, leading to bradycardia.
- 22. A severe vascular emergency where a tear in the inner layer of the aorta allows high-pressure blood to split the arterial wall layers.
- 23. An abnormal expansion of blood volume in the intravascular compartment, leading to elevated central venous pressures.
- 24. The physical opposition encountered by blood as it flows through the vascular system, dictated heavily by arteriolar radius.
- 25. An intravascular volume depletion state resulting from severe hemorrhage, dehydration, or extensive third-spacing fluid shifts.
- 26. The structural distensibility of a blood vessel wall, representing the volume change achievable per unit change in pressure.
- 27. The pathological condition where a blood clot detaches from its original site of formation and travels to occlude a distant vessel.
- 28. The intrinsic ability of local tissues and organs (such as the brain or kidneys) to maintain constant blood flow despite pressure shifts.
- 29. The physiological process of delivering blood through the capillary bed into an organ or tissue to satisfy structural demands.
Down
- 1. The study and clinical measurement of blood flow, physical pressures, and mechanical forces within the cardiovascular plumbing circuit.
- 2. A type of distributive shock triggered by an IgE-mediated hypersensitivity reaction, causing massive systemic histamine release.
- 4. A potent plasma peptide converted by lung enzymes that acts as a powerful vasoconstrictor and triggers aldosterone synthesis.
- 5. The palpable accumulation of excess fluid within the interstitial tissue spaces, often driven by altered capillary pressures.
- 7. An accelerated phase of hypertension characterized by extremely high pressures and rapid target-organ damage like encephalopathy.
- 13. Inflammation of a vein accompanied by the formation of a blood clot, frequently occurring in the lower extremities.
- 14. A form of low blood pressure that occurs when shifting from a supine or sitting position to an upright standing posture.
- 15. The intricate network of arterioles, capillaries, and venules where physical exchange of nutrients and gases occurs.
- 18. A localized structural outpouching or ballooning of a weakened arterial wall, carrying a permanent risk of catastrophic rupture.
- 21. A vascular disorder characterized by episodic vasospastic attacks in digital arteries, typically triggered by cold exposure or emotional stress.
- 30. The specialized, continuous single layer of cells lining the entire vascular system, crucial for nitric oxide production.
