- What is a consequense of unusually high concentration of CO2 in her blood stream at all times? a. blood vessels will always be constricted b. osmotic pressure will forge water out of capillaries closer to the vebueks than is typical c. co2 will build up in cells following aerobic respiration d. more transporter proteins will be needed to move co2 out of blood streamarrow_forwardChronic hypoxia due to heavy tobacco smoking is likely to lead to an increase in which of the following (select all that apply)? a. Erythropoietin b. Platelet count c. White blood cell count d. Red blood cell countarrow_forwardAs bicarbonate ions attach to erythrocytes, the balance between positively and negatively charged ions is disturbed, causing the chloride shift. As the bicarbonate ions leave the erythrocyte, there is a decrease in the negative charge, which is relieved by the diffusion of Cl- into the erythrocytes. a. Both statements are correct b. Both statements are incorrect c. First is correct; Second is incorrect d. First is incorrect; Second in correctarrow_forward

- Which of the following situations occurs if a person's blood becomes more alkaline? A. Hemoglobin molecules retain less oxygen per heme group under alkaline conditions than they do at neutral pH or under acidic conditions. B. Hemoglobin molecules give up oxygen more readily under alkaline conditions than they do under neutral pH or under acidic conditions. C. Hemoglobin molecules change shape and begin to lose oxygen molecules. D. Hemoglobin molecules retain oxygen more readily under alkaline conditions than they do at neutral pH or under acidic conditions. E. There is no change in hemoglobin's oxygen-binding affinity under alkaline conditions when compared to blood at neutral pH or under acidic conditions.arrow_forwardThe content of ATP/ADP was considerably diminished in blood cells which was accompanied with the increase of time of bleeding as a result of hemostasis violation directly during the development of: A. reversible aggregation of thrombocytes B. irreversible aggregation of thrombocytes C. adhesion of thrombocytes D. hemocoagulation E. thromb's retractionarrow_forwardThe term "hematopoiesis" refers to: Select one: a. a disease in which there is insufficient blood cell production b. the process of blood cell formation c. the mechanisms that prevent blood loss d. the rupture of red blood cells Question 51arrow_forward
