Why do cardiovascular disorders inevitably lead to respiratory disorders and vice versa? Critically discuss why cardiovascular disorders inevitably lead to respiratory disorders, and vice versa. (b) Why are these important to the cardiovascular system? so since there is a threshold amount of air that is released from each individuals lungs then there wouldn't be a change with or without exercise. Vital capacity is the maximum amount of air that can be breathed out after breathing in as much air as possible. Inspiratory capacity is the amount of air taken in during a deep breath, while residual volume is the amount of air left in the lungs after forceful respiration. The general rule is that FRC decreases with exercise. What is the role of the cardiovascular system and why it is important?
