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.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
