B: increased return of tissue fluid
C: constriction of blood storage organs such as liver and spleen
D: increased capillary hydrostatic pressure

举一反三
- The "autotransfusion" at the early stage of shock is due to A: constriction of capacity vessels and organs such as liver and spleen B: increased blood return from the thoroughfare channel C: arteriole constriction D: opening of arteriovenous shunt E: aortic constriction
- The mechanism of lower extremity edema in patients with right heart failure does not include: A: Increased capillary permeability B: Retention of sodium and water C: Systemic venous congestion D: Hypoproteinemia E: Increased capillary hydrostatic pressure
- 5. The characteristics of microcirculation in late shock stage are: A: A. Increased forward resistance and significantly decreased perfusion and slower blood flow through the capillary network. B: B. Increased rear resistance and significantly increased perfusion and slower blood flow through the capillary network. C: C. The microvessels are paralytically dilated, no perfusion and blood flow through the capillary network. D: D. Continuous spasm and contraction of microcirculation.
- In the progressive stage of shock, the microcirculation was mainly presented A: microcirculation ischemia B: microcirculation Congestion C: microcirculation Blood coagulation D: microcirculation Failure
- The formation of exudate is mainly due to ( ) A: Increased intravascular hydrostatic pressure B: Decreased intravascular colloid osmotic pressure C: Obstruction of lymphatic drainage D: Increased vascular permeability
