Question

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. A) respiratory; nervous B) respiratory; muscular C) respiratory; digestive D) respiratory; circulatory

Answer 1

B - Respiratory; Muscular

Step-by-step explanation:

Asthma is a common pulmonary condition defined by chronic inflammation of respiratory tubes, tightening of respiratory smooth muscle, and episodes of bronchoconstriction. During an asthma attack greater pressure is needed to push air through the bronchus ( respiratory system). This results in the increased use of accessory muscles ( muscular system) to breathe. These muscles are attached to the ribs, shoulders and neck. This extra work results in sweating, fatigue and airway irritation
