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

The correction is B.
The respiratory system is the one that is responsible for transportation of oxygen from the outside to the lungs and the reverse transportation of carbon dioxide from the body to the atmosphere. The muscular system is responsible for the contraction of muscles around the air passages during respiration. These two systems are negatively affected in asthma patients during respiration.

Answer 2

Answer:

B - Respiratory; Muscular

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
