Unit 1.2: There are three types of fluid associated with the circulatory system: Fluids! Contents of Blood 1. Blood 2. 3. Blood is the medium of transport for all of the different things that our cells need to function. Label this diagram of the cardiovascular system, indicating what each structure is (in squares), and what pressure each structure’s blood will be at: How is Tissue Fluid Made? Tissue fluid is the liquid that allowing for transport between the blood and cells. This transport occurs via . walls are partially permeable, allowing some things to pass from the blood to the tissue. This is a key factor in the formation of tissue fluid. Tissue fluid is formed due to an interplay of: 1. MOVES WITH FLUID (TOO BIG!) DOES NOT MOVE WITH FLUID Why is the blood within the capillaries of a more negative water potential than the fluid outside? Water moves down the water potential gradient and Fluid movement is a net figure calculated by subtracting water potential effects from hydrostatic pressure. Outline some things that move with the fluid. through in their walls. but there is a net ward movement of fluids.What is the main source of hydrostatic pressure? Hydrostatic pressure forces fluid out of the capillaries. A small hydrostatic pressure in the tissue forces some fluid back into the capillaries. and some things that do not. Hydrostatic pressure is much greater at the of the capillary. meaning that net fluid movement changes along . Some of this is eventually reabsorbed. and a net at the venous end. There is a net of fluid from the arterial end of capillaries. Note that not all fluid passes back into the capillaries. .Fluid moving out of the capillaries forms the tissue fluid. The net excess is drained into vessels of the -this fluid is now known as Lymph passes through the lymphatic system and drains back into the Lymph contains (type of white blood cell) which are made in Lymphocytes are part of the and help to filter out foreign material from the lymph. When removing breast cancer tumours. What do you think the effects would be on that person’s blood pressure? 2. Blood Tissue Fluid Lymph Erythrocytes Lymphocytes Plasma Proteins Oxygen Carbon dioxide Questions: 1. The heart of a person suffering from heart failure is very inefficient.Complete the table to show the relative amounts of each thing within each of the three fluid types.CONSOLIDATION TABLE . How would low blood pressure affect the formation of tissue fluid? Explain your answer. . 3. there is a risk of damaging the lymphatic drainage of in the arm. What do you think the result of such damage would be? Explain your answer.
