Lymphatic System and Tissue Fluid

This video tutorial explains the function and formation of tissue fluid and lymph fluid. It covers the components of blood, including red and white blood cells, plasma, and platelets. The video details how tissue fluid is formed in capillaries, the roles of hydrostatic and oncotic pressure, and the process of ultrafiltration. It also discusses the lymphatic system's function in fluid return and immunity.

Which component of blood is responsible for transporting oxygen?

• Red blood cells

• Plasma proteins

• White blood cells

• Platelets

What is the primary function of tissue fluid as described in the video?

• To produce plasma proteins

• To transfer molecules like oxygen and glucose to tissue cells

• To transport blood cells

• To store waste molecules

What is the role of plasma proteins in blood plasma?

• They store glucose

• They are involved in blood clotting

• They lower the water potential of blood plasma

• They transport oxygen

What process describes the movement of tissue fluid out of the capillaries?

• Diffusion

• Ultrafiltration

• Osmosis

• Active transport

At the arterial end of the capillary, which pressure is greater?

• Oncotic pressure

• Hydrostatic pressure

• Atmospheric pressure

• Osmotic pressure

What happens to the tissue fluid at the venous end of the capillary?

• It is converted into plasma

• It is absorbed by the tissue cells

• It remains in the tissue

• It is reabsorbed into the blood

What percentage of tissue fluid is reabsorbed back into the blood?

• 90%

• 50%

• 100%

• 70%

What is the function of lymph capillaries in the lymphatic system?

• To store glucose

• To produce plasma proteins

• To drain excess tissue fluid

• To transport red blood cells

How does lymph fluid move through the lymphatic system?

• By the contraction of skeletal muscles

• By gravity

• By diffusion

• By active transport

Where does the lymph fluid eventually return to the bloodstream?

• In the kidneys

• In the liver

• In the heart

• Under the collar bone
