Choices:
Step by step
Solved in 2 steps
- Countercurrent flow of blood and water is more efficient than concurrent flow because a … is maintained which drives oxygen from water to bloodThe vascular system delivers blood by a network of vessels, this process is regulated by the dynamics of fluid flow. State at least four factors that may affect this flow . Describe how fluid flow changes with respect to them.Along a capillary, _____ dominates at the arterial end and fluid moves _____; _____ dominates at the venous end and fluid moves _____. (a) osmosis, in; filtration, out (b) filtration, out; osmosis, in (c) filtration, in; osmosis, out (d) osmosis, out; filtration, in
- The vascular system delivers blood by a network of vessels, this process is regulated by the dynamics of fluid flow. State at least four factors that may affect this flowUnderline the correct solution: Water (flows into) (moves into and out of) capillaries.Osmotic pressure is measured with a _____________.
- Which of the following statements is false concerning the movement of fluid between capillaries and interstitial space? Group of answer choices The osmotic pressure of the interstitial fluid does not oppose the movement of fluid from the capillary. Blood hydrostatic pressure forces fluid from the capillary to the interstitial space. The blood hydrostatic pressure and the blood osmotic pressure are always equal in magnitude but opposite in direction. Blood osmotic pressure moves fluid from the interstitial space to the capillary. The osmotic pressure of the interstitial fluid is less than the blood osmotic pressure.Two solutions are separated by a semipermeable membrane that is permeable only to water. The two solutions are: Solution A = 150 mM KCl Solution B = 150 mM Angiotensin (a 7 amino acid polypeptide) Which of the following would best explain the net movement in this situation? - water will move from the KCl side to Angiotensin side - water will move from Angiotensin side to KCl side - The Cl- ion will move to the angiotensin side until there is 75 mM Cl- on each side - Since Angiotensin is not an ion, it can move through the membrane - There is no net water movement as the concentrations are the same on both sidesIn circulatory system, one the main function of our blood is maintaining pur body pH Explain further this : – Blood regulation fuctions maintaining normal pH using buffers; alkaline reserve of bicarbonate ions
- What is the main reason that fluid is forced out of the capillaries as they enter? The hydrostatic pressure of the blood is less than that of the interstitial fluid. The osmotic pressure of the blood is greater than the hydrostatic pressure of the interstitial fluid. The osmotic pressure of the interstitial fluid is greater than the hydrostatic pressure of the blood. The hydrostatic pressure of the blood is greater than the osmotic pressure of the blood. The osmotic pressure of the interstitial fluid is greater than that of the blood.The volume of a red blood cell will remain unchanged in... 1) distilled water, a isotonic solution 2) 150 mM NaCl, an isotonic solution 3) 150 mM glucose, an isotonic solution 4) 150 mM MgCl2, an isotonic solutionWhich of the following is/are true of a circulatory system (=fluid-transport system): Group of answer choices is an adaptation to large body size. All of the other choices are true. aids diffusion by reducing functional diffusion distances transports substances rapidly between distant cells/tissues.
