Please I need help ASAP.
33) The circulatory route that runs from the digestive tract to the liver is called 33)_ A) pulmonary circulation C) hepatic portal circulation B) coronary circulation D) cerebral circulation 34) 34) Aldosterone will A) result in a larger output of urine C) decrease sodium reabsorption B) promote an increase in blood pressure D) promote a decrease in blood volume 35) 35) The pulse pressure is A) systolic pressure minus diastolic pressure B) systolic pressure divided by diastolic pressure C) systolic pressure plus diastolic pressure D) diastolic pressure plus 1/3 (systolic pressure plus diastolie pressure) 36) 36) Which of the following signs of hypovolemic shock is a relatively late sign? A) rapid, thready pulse C) increased heart rate B) rapidly falling blood pressure D) cold, clammy skin 37) 37) Which of the following is true about veins? A) Veins have a small lumen in relation to the thickness of the vessel wall. B) Veins are called capacitance vessels or blood reservoirs. C) Venous valves are formed from the tunica media. D) Up to 35% of total body blood is in venous circulation at any given time. 38) 38) Brain blood flow autoregulation A) causes constriction of cerebral blood B) is abolished when abnormally high CO2 levels persist C) is controlled by cardiac centers in the pons D) is less sensitive to pH than to a decreased oxygen level vessels in response to a drop in systemic blood pressure 39 39) The influence of blood vessel diameter on peripheral resistance is A) the only factor that influences resistance B) insignificant because vessel diameter does not vary C) significant because resistance is directly proportional to the blood vessel diameter D) significant because resistance is inversely proportional to the fourth power of the vessel radius 40) 40) In the dynamics of blood flow through capillaries, hydrostatic pressure A) is the same as capillary blood pressure B) generally forces fluid from the interstitial space into the capillaries C) and osmotic pressure are the same D) is completely canceled out by osmotic pressure 41) A) a condition of the aged in which the arteries lose elasticity B) a special fetal vessel that allows umbilical blood to bypass the liver C) damage to the valves in the veins, leading to varicose veins D) a fetal shunt that bypasses the lungs 41) The term ductus venosus refers toExplanation / Answer
33.C. Hepatic portal circulation
The hepatic portal circulation is responsible for directing blood from parts of the gastrointestinal tract to the liver.
34. B Promote an increase in blood pressure
Aldosterone causes the kidneys to hold more sodium therefore concentration of water increases in blood . The more fluid the body holds ,higher is the blood pressure.
35. A. Systolic pressure minus diastolic pressure
Pulse pressure is the difference between the systolic and diastolic blood pressure.
36.B, C, D
The signs are increased heart beat,rapidly falling blood pressure and cold and clammy skin.
