Cyanide acts as a mitochondrial poison by blocking the final step in the electron transport chain. Which of the following is notВ a function of plasma proteins in humans? a. enlargement of clefts between capillary endothelial cells _ 13. decrease of the systolic blood pressure e. removal of an obstruction in the lymphatic system d. constriction of the smooth layer of the arteriole c. decrease of plasma protein production by the liver b. If a person were suffering from edema, which of the following conditions would help to reduce the accumulation of interstitial fluid? a. plasma proteins will escape through the endothelium of the capillaries. most carbon dioxide will be bound to hemoglobin and carried away from tissues. the pH of the interstitial fluids will increase. fluids will tend to accumulate in tissues. If, during protein starvation, the osmotic pressure on the venous side of capillary beds drops below the hydrostatic pressure, then a. 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 hydrostatic pressure of the blood is less than that of the interstitial fluid. The osmotic pressure of the interstitial fluid is greater than that of the blood. What is the reason that fluid is forced out of systemic capillaries at the arteriole end? a. Nothing will happen in healthy individuals. Blood pressure will initially increase and then immediately decrease. There will be a transient decrease in blood pressure. The extra pressure exerted by the inflating lungs will increase blood pressure. The systolic pressure would rise and the diastolic pressure would decrease. What can be expected to happen to the blood pressure of a healthy individual during inhalation? a. would have an effect on blood pressure monitors in the aorta.Д©. would disrupt the rate and timing of cardia muscle contractions. would have a negative effect on peripheral resistance. would block conductance between the bundle branches and the Purkinje fibers. Damage to the sinoatrial node in humans a. The heart would need to have multiple ostia. The heart would need to have multiple chambers. The circulating body fluid would need to be contained in closed vessels. In order for an insect to grow as large as an elephant, what changes or modifications would need to be made in the circulatory systems of insects? a. Blood is carried directly to the lungs from which of the following? a. Chambers or vessels that carry oxygenated blood include which of the following? a.

To adjust blood pressure independently in the capillaries of the gas-exchange surface and in the capillaries of the general body circulation, an organism would need a(n) a. one one atr atriu ium m two two ven ventr tric icle lessД¤. no atri atria a thre threee ven ventr tric icle less e. thre threee atr atria ia no no ven ventr tric icle less d. two two atr atria ia one one vent ventri ricl clee c. one one atr atriu ium m one one ven ventr tric icle le b. Three-chambered hearts generally consist of which of the following numbers of atria and ventricles? a. In which animal does blood flow from the pulmocutaneous circulation to the heart before circulating through the rest of the body? a. Which of the following blood components would interfere with with the functioning of an open circulatory system but notВ a closed one? a.
