1) What are networks of capillaries in tissue called? a) Capillary membrane b) Capillary bed c) Capillary mattress d) Capillary wall 2) What is tissue fluid made of? a) Oxygen, water, red blood cells b) Oxygen, proteins, water c) Oxygen, water, nutrients 3) Next to the Arteriole, what is the hydrostatic pressure like in the capillaries? a) Lower, so tissue fluid moves in to blood b) Greater, so molecules move into tissue fluid c) Greater, so tissue fluid moves in to blood d) Greater, so tissue fluid moves in to blood 4) Fluid containing molecules from blood moves into tissue fluid surrounding them: why? a) Osmotic potential difference b) Hydrostatic pressure difference c) Concentration gradient difference 5) Hydrostatic pressure reduces in the capillaries. What does this mean for pressure further along in the venule end of the capillary bed? (diagram for reference) a) Equal b) Lower c) Higher 6) Water potential at the venule end is lower (caused by lower hydrostatic pressure as there's less fluid) why? a) Fluid loss, yet still large plasma proteins b) Fluid loss, and loss of plasma proteins c) Fluid loss, and increase in salts 7) Now there is a lower water potential inside the capillary, which way will water move? a) From tissue fluid to cells b) From capillary to tissue fluid c) From tissue fluid to capillary d) From cells to tissue fluid 8) What is now in tissue fluid, after this process? a) Water, nutrients, and oxygen b) Water, plasma proteins, blood cells c) Water, oxygen, carbon dioxide 9) What happens to this tissue fluid? a) It is lost in sweat b) It travels to the colon to make solid waste softer c) It is drained by the lymphatic system
