BLOOD, TISSUE FLUID AND LYMPH 0.0 / 5 ? BiologyTransport in animalsASOCR Created by: JimanthaPickensCreated on: 28-03-20 04:14 What substance is NOT forced out of the arterial end of the capillaries? Plasma proteins 1 of 18 What causes the high hydrostatic pressure in the arterial end of the capillaries? Contractions of the heart 2 of 18 What is the name of the fluid that circulates in the lymphatic system? Lymph 3 of 18 Why can't plasma proteins and red blood cells be forced out of the capillaries? Too big to fit through the gaps between the capillary cell walls 4 of 18 What does lymph contain? Lymphocytes, fatty acids, carbon dioxide, antibodies 5 of 18 What does tissue fluid contain? Oxygen, dissolved solutes, few white blood cells 6 of 18 What is the name of the fluid that surrounds the cells of the body? Tissue fluid 7 of 18 At the arterial end of the capillaries, what is the net movement of fluid? Net loss of fluid 8 of 18 At the venous end of the capillaries, what is the net movement of fluid? Net gain of fluid 9 of 18 What is the name of the process that involves plasma moving out of the capillaries? Ultrafiltration 10 of 18 How does lymph travel through the lymphatic system? Contraction of skeletal muscles through lymph vessels 11 of 18 Where are lymph nodes found? Along the lymph vessels 12 of 18 What is the oncotic pressure? The tendency of water to move into the blood by osmosis 13 of 18 The approximate value of the oncotic pressure: -3.3kPa 14 of 18 Why is elastic tissue present in the walls of the arteries? To stretch and recoil in order to maintain high pressure 15 of 18 What is NOT a feature of a closed circulatory system? Blood travels through the heart once in a circulation 16 of 18 Why do multicellular organisms need specialised transport systems? SA:V ratio gets smaller as the organism gets bigger so diffusion distance increases- diffusion no longer effective 17 of 18 Why does the blood within the capillaries have a lower water potential than the fluid outside? The plasma proteins decreases the water potential 18 of 18
