EACH STATEMENT IS A T/F QUESTION PLEASE ANSWER ALL12
Pulmonary function limits physical performance because transittime through the pulmonary capillaries is reduced to 0.4 secondsduring maximal exercise which is not enough time for completeoxygenation of the blood.
Oxygen binds to the globin portion of the hemoglobinmolecule.
HCO3- diffuses out to plasma at tissue level and chloride (Cl-)into the RBC, known as chloride shift.
Carbonic anhydrase is present in the RBC and catalyzes theformation of lactate.
During exercise, tidal volume does not change relative to tidalvolume at rest
Alveoli are the lung structure where gas exchange takesplace.
Partial pressure of a specific gas affects the driving forcebehind that gas.
The immediate and largest increase in ventilation duringexercise is due to changes to chemistry of arterial blood.
An increase in pH is in part responsible for the Bohreffect.
Inhalation is an active process, it involves contraction of thediaphragm.
Cooperative binding refers to the ease at which O2 binds to Hbwith each subsequent O2.
HCO3- (bicarbonate) accounts for the majority of CO2transport.
