Answer:

"Ventilation was occurring, but perfusion was inadequate causing shortness of breath. "

Explanation:

Uneven changes in airflow resistance, the resulting uneven distribution of air, and alterations in circulation from increased intra-alveolar pressure due to hyperinflation all lead to ventilation-perfusion mismatch. Vasoconstriction due to alveolar hypoxia also contributes to this mismatch. For effective gas exchange to occur, alveoli must be ventilated and perfused. Ventilation (V) refers to the flow of air into and out of the alveoli, while perfusion (Q) refers to the flow of blood to alveolar capillaries.

Why do we need the endocrine system?
GenaCL600 [577]

Explanation:

The endocrine hormones help control mood, growth and development, the way our organs work, metabolism , and reproduction. The endocrine system regulates how much of each hormone is released. This can depend on levels of hormones already in the blood, or on levels of other substances in the blood, like calcium.

Without your endocrine glands — and the hormones they release — your cells wouldn't know when to do important things. For instance, your bones wouldn't get the message that it's time for you to grow and get bigger.

hope it helps!
