Answer:

respiratory and muscular

Explanation:

Asthma affects the respiratory and muscular systems and causes them to work harder to supply the oxygen deficit caused by the disease.

Asthma, also known as asthmatic bronchitis, is a chronic disease that affects about 150 million people worldwide. It is characterized by inflammation of the airways. We call "chronic disease" pathologies that recur over the course of more than three months, or often throughout the life of the individual. The inflammatory process may start for several reasons. In many cases, exposure to potentially allergenic elements - such as dust, mites, and pollen - triggers this immune system response. In others, airway irritants - such as pollution, cigarette smoke and strong smells - are responsible.
