Grade 12 Biology Quiz: Tissue Fluid Formation and Blood Vessels

What is the primary method of capillary exchange?

• Convection, absorption, and excretion

• Active transport, pinocytosis, and phagocytosis

• Diffusion, filtration, and osmosis

• Secretion, reabsorption, and respiration

How does the process of diffusion contribute to capillary exchange?

• By increasing the size of the capillaries

• By allowing for the exchange of gases, nutrients, and waste products between the blood in the capillaries and the surrounding tissues.

• By preventing the exchange of gases and nutrients

• By causing blood to clot in the capillaries

What is the role of osmotic pressure in the formation of tissue fluid?

• Osmotic pressure has no role in the formation of tissue fluid

• Osmotic pressure helps in the movement of water from the blood capillaries into the interstitial space, forming tissue fluid.

• Osmotic pressure causes the movement of tissue fluid back into the blood capillaries

• Osmotic pressure prevents the movement of water from the blood capillaries into the interstitial space

Explain how the balance between hydrostatic and osmotic pressure maintains tissue fluid formation.

• By decreasing the movement of fluid into the blood vessels

• By increasing the movement of fluid out of the blood vessels

• By regulating the temperature of the tissue fluid

• The balance between hydrostatic and osmotic pressure maintains tissue fluid formation by regulating the movement of fluid into and out of the blood vessels.

What factors affect the osmotic pressure in tissue fluid?

• Type of tissue, location of the blood vessels, and age of the individual

• Color of the tissue fluid, size of the blood vessels, and pH level

• Amount of oxygen in the tissue fluid, presence of white blood cells, and blood pressure

• Concentration of solutes, permeability of the membrane, and temperature

Discuss the impact of osmotic pressure on the movement of water in and out of capillaries.

• Osmotic pressure causes water to move out of capillaries into the interstitial fluid.

• Osmotic pressure has no impact on the movement of water in and out of capillaries.

• Osmotic pressure causes water to move into arteries from the capillaries.

• Osmotic pressure causes water to move into capillaries from the interstitial fluid.

What are the three main types of blood vessels and their functions?

• Capillaries, capillaries, and capillaries

• Arteries, veins, and capillaries

• Arteries, arteries, and arteries

• Veins, veins, and veins

Describe the structure and function of arteries.

• Arteries have thin, non-muscular walls to carry deoxygenated blood to the heart.

• Arteries have thick, muscular walls to withstand high pressure and carry oxygenated blood away from the heart to the rest of the body.

• Arteries carry blood from the rest of the body to the heart.

• Arteries have no specific structure and function.

Explain the role of veins in the circulatory system.

• Veins help in the exchange of gases in the lungs.

• Veins are responsible for pumping blood to the rest of the body.

• Veins carry oxygenated blood away from the heart to the body's tissues.

• Veins carry deoxygenated blood back to the heart from the body's tissues.

Discuss the structure and function of capillaries in the body.

• Capillaries are not involved in the exchange of substances between the blood and tissues.

• Capillaries are only found in the muscles and not in other tissues.

• Capillaries have thick walls that prevent the exchange of substances between the blood and tissues.

• Capillaries have one-cell thick walls that allow for the exchange of substances between the blood and tissues.
