low Hp of blood ___.  which is correct?    a. decreases the O2 available for tissues b. facilitates O2 dissociation from hemoglobin  c. decreases level of hydrogen ions  d. increases hemoglobins affintiy to CO2

During exercise your pCO2 levels rise to 50 mm Hg while your pO2 levels drop to 80 mm Hg. Your peripheral chemoreceptors will be primarily sensitive to:   A the increase in pCO2 B the decrease in pO2 C both the increase in pCO2 and decrease in pO2 D the increase in pCO2 and resulting increase in MAP E the decrease in pO2 and resulting increase in MAP

The steep part of the O2-Hb dissociation curve... a. is where CO2 unloading occurs at the tissue cells b. is where the PO2 is high (>90mmHg) c. is where the oxyhemoglobin is high (>90 % saturated) d. is where O2 unloading occurs at the tissue cells

Which of these factors in active tissue does not lead to greater release of O₂ from hemoglobin? elevated temperature O increased acidity O All of the other choices lead to increased release of oxygen O elevated carbon dioxide In anemia, the blood has low levels of hemoglobin and carries less oxygen (this is TRUE). Question: Does anemic blood have reduced PO2 compared with the PO2 of blood with normal hemoglobin levels? O Yes O No
