Aerobic chronic adaptations

Question 1

increased lung volume

Answer 1

leads to an increased tidal volume ( amount inspired and expired per breath)

Question 2

greater alveolar- capillary surface area

Answer 2

leads to more sites for gas exchange ( increased pulmonary diffusion).

Question 3

increased left ventricle size

Answer 3

increased stroke volume ( amount of blood that heart pumps per beat)
decreased steady state heart rate.

Question 4

increased in the density of capillarisation that surround the working muscles

Answer 4

means increased sites for gas exchange. o2 from blood to muscles. therefore greater blood flow.

Question 5

increased blood plasma ( fluid)

Answer 5

increased blood volume
