- How is your breathing related to your cellular respiration?arrow_forwardWhich of the following statements about oxygen transport is TRUE. Increases in temperature and decreases in pH cause myoglobin to release oxygen to improve delivery to the hemoglobin in muscles. A molecule of myoglobin has higher oxygen binding capacity than a molecule of hemoglobin. Myoglobin has a higher oxygen affinity than does hemoglobin. Fetal hemoglobin has a lower affinity for oxygen than maternal hemoglobin, which makes it better suited to extract oxygen from the maternal circulation.arrow_forwardThe movement of air out of the lungs during normal expiration is a result of? Air moves out of the lungs due to the relaxation of the diaphragm and intercostal muscles. Air moves out of the lungs due to the passive elastic recoil of the chest wall and lungs. Air is forced out of the lungs due to the active contraction of the abdominal and external intercostal muscles.
