BIOS255 Exam 2 Review: Blood Vessels and Lymphatic
System
Question 1.
Cardiac output (CO)
Correct Answer: Volume of blood pumped by left ventricle per minute.
Question 2.
Primary Lymphatic Organs
Correct Answer: Sites for B and T cell generation and maturation.
Question 3.
Diffusion
Correct Answer: Movement of substances across capillary walls by concentration
gradient.
Question 4.
Net Filtration Pressure (NFP)
Correct Answer: NFP = (BHP + IFOP) - (BCOP + IFHP).
Question 5.
Large veins
Correct Answer: Largest veins, example is inferior vena cava.
Question 6.
Aldosterone
Correct Answer: Hormone promoting sodium retention, affecting blood volume.
Question 7.
Perfusion
Correct Answer: Flow of blood to a specific tissue.
Question 8.
Natriuretic peptides
Correct Answer: Hormones that reduce blood pressure by promoting fluid loss.
Question 9.
Baroreceptors
Correct Answer: Sensors in carotid sinus responding to blood pressure.
Question 10.
Vascular resistance (R)
Correct Answer: Opposition to blood flow in vessels.
Question 11.

, Thymus
Correct Answer: Site of T-cell maturation, shrinks with age.
Question 12.
Local Auto Control
Correct Answer: Intrinsic regulation of blood vessel diameter.
Question 13.
Blood vessel diameter
Correct Answer: Influences resistance; constricted vs dilated.
Question 14.
Capillaries
Correct Answer: Site for nutrient and waste exchange, only tunica intima.
Question 15.
Chemoreceptors
Correct Answer: Detect changes in blood pH, O2, and CO2.
Question 16.
Catecholamines
Correct Answer: Hormones (epinephrine, norepinephrine) that increase heart
rate.
Question 17.
Fluid Recovery
Correct Answer: 85% tissue fluid reabsorbed by blood capillaries.
Question 18.
Aneurysm
Correct Answer: Weak vessel wall causing bulging, pulsates with heartbeat.
Question 19.
Systolic pressure
Correct Answer: Pressure during heart contraction.
Question 20.
Edema
Correct Answer: Excess fluid accumulation in tissues.
Question 21.
Veins
Correct Answer: Contain valves, assist blood return to heart.
Question 22.
Capillary Exchange
