2015优化一轮复习生物必修3-36（2015 optimize one round of revision biology required 3-36） Zhang Bei learning plan system, daily share A choice The following 1. of the bodys internal environment description, the error is () The main component of the A. plasma including water, glucose, hemoglobin and hormone Steady on the internal environment plays an important role in immune B. C.HCO3, HPO42 and other involved in the maintenance of plasma pH is relatively stable The liquid environment D. lymphocyte life is lymph and plasma Resolution: A. Hemoglobin is in red blood cell protein belongs to the intracellular fluid, does not belong to the plasma composition; immune regulation can identify the internal environment in their composition, non self compositions in the internal environment, so as to maintain each part of the internal environment is relatively stable; plasma exists in HCO3 / H2CO3, HPO42 /H2PO4 etc. the plasma pH buffer to maintain relatively stable; lymphocytes in lymphatic vessels, can enter the bloodstream through the lymphatic circulation, so the internal environment including lymph and plasma etc.. About 2. of the bodys internal environment of the following statements is true (). The A. component of hemoglobin, oxygen and amino acids belong to the internal environment B. the internal environment of lymphatic capillary plasma and tissue fluid and lymph C. saliva, antidiuretic hormone can exist in the environment D. skin cuticle cells dissociated from the outside environment Resolution: D. The internal environment is the liquid environment for cell survival in human tissues, cells only through the internal environment and external environment, can indirectly carry out the exchange of substances. Simply speaking, internal environment refers to the extracellular fluid, rather than intracellular fluid. Under normal circumstances, only exists in the hemoglobin in red blood cells, while glucose, amino acids, carbon dioxide and oxygen are present in plasma. The specific envir
