Answer: arteriosclerosis
2. stiffening of blood vessel walls due to lipid deposits
Answer: atherosclerosis
3. resistance to flow , blood volume, cardiac output
Answer: principal variables thatphysiologically determine blood pressure
4. the amount of blood pumped out of the left ventricle per minute so it willdirectly
influence blood pressure in the blood vessels.
Answer: cardiac output
5. control blood vessel diameter
Answer: local auto control, neural control, hormonalcontrol
6. (neural control) negative response, carotid bodies in carotid sinus
Answer: baroreceptors
7. (neural control) response to changes in blood pH and O2 and CO2 concentrations
Answer: chemo
8. (neural control) sympathetic and parasympathetic innervation
Answer: medullaryischemic reflex
9. type of capillary exchange, substances such as oxygen, carbon dioxide, glucose, amino
acids, and some hormones cross capillary walls via simplediffusion
Answer: diffusion
10. type of capillary exchange, large, lipid-insoluble molecules, cross capillarywalls in vesicles
Answer: transcytosis
11. type of capillary exchange, a passive process in which large numbers ofions, molecules
Answer: bulk flow
12. BHP and IFOP
Answer: 2 factors that promote filtration
13. BCOP and IFHP
Answer: 2 factors that oppose filtration
, 14. increased in hydrostatic pressure or an increase in capillary permeabilitymay increase the
amount of water that filters out into surrounding tissue
Answer: in-creased capillary filtration
15. lack of albumin in blood plasma reduces the reabsorption of tissue fluid-
Answer: reduced capillary reabsorption
16. if the lymphatic vessels have a blockage, then lymph is unable to returnto the bloodstream
and accumulates in tissue fluids
Answer: obstructed lymphatic drainage
17. pulmonary trunk, right and left pulmonary arteries, pulmonary capillaries,pulmonary
veins
Answer: pulmonary system
18. common carotids, internal carotids, external carotids, vertebral arteries,circle of willis
Answer: arterial blood supply to the brain
19. carotid sinus
Answer: monitor blood pressure and adjust HR, found in the internalcarotid artery
20. smooth muscle in all three layers
