Asthma narrows airways to the lungs and in the lungs by contraction of muscles around the air passages, swelling of the airway lining, and build-up of excessive mucus. because of this, asthma makes both the and systems work harder to deliver oxygen to the cells throughout the body.

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.

this is math not biology xd

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
