Describe the structure of the veins and how it's related to its function

Describe the structure of the capillaries and how this makes them adapted for their function

What is tissue fluid?

Explain what causes the decrease in water potential at the arterial end of the capillary

Explain what causes the increase in water potential towards the venous end of the capillary

How is tissue fluid formed and how may it be returned to the circulatory system?

What's one difference in the composition of blood plasma and tissue fluid? What causes this difference?

What's the role of proteins in blood plasma in returning fluid to the capillary?

What's the function of the lymphatic vessels? (in relation to tissue fluid)

Explain how the active transport of mineral ions into xylem vessels in the roots results in water entering these vessels and then being moved up the xylem tissue

Why does the presence of an air bubble in the xylem block the movement of water?
