Exam 2 Review AP 2

  If a person develops high blood pressure, one of the compensatory mechanisms that comes into play is the fluid shift mechanism. This mechanism causes

• water to shift from inside cells into the extracellular fluid

• water to shift from the capillaries into the interstitial spaces

• water to shift from the interstitial space into the capillaries.

• water to shift from the interstitial space into the capillaries.

Which of the following is NOT involved in short-term regulation of blood pressure?

•     Chemoreceptor mechanism

  When blood pressure is greater than the blood colloid osmotic pressure, there is

• a net movement of fluid into the capillary.

• a net movement of fluid out of the capillary.

• less lymph formed.

•   a decrease in the volume of the interstitial fluid.

The chemoreceptor reflexes help maintain homeostasis

• under normal conditions.

•   when CO2 levels increase.

• when epinephrine levels increase.

•    when H⁺ concentrations decrease.

Veins

•   carry blood away from the heart.

• carry blood under very high pressure.

• may contain valves and are lined with endothelium.

• are described as strong, rigid vessels that always carry oxygenated blood.

Valves similar to the semilunar valves of the heart are found in medium and large_________.

•      arteries

•   arterioles

•   venules

•   veins

When contrasting arteries and veins, which of the following statements is true?

• Veins have thicker walls than arteries.

• Arteries have a thicker tunica media than veins.

•    Veins have a tunica media, while arteries do not.

•    Arteries have valves, but veins do not.

Distributing arteries

• contain a lot of elastic tissue

• contain a thick tunica media

• are strong, rigid vessels

• transport blood from arterioles to capillaries

   Which of the following best describes arteries?

•   Strong, rigid vessels that carry blood under high pressure

• Strong, elastic vessels that carry blood under high pressure

• Fragile vessels that are prone to rupture

•    Elastic vessels that connect arterioles and venules
