Answer:
Oxygen enters the lungs through the trachea, which branches into two tubes called the bronchi, which lead to the lungs.
The process of heart contraction stimulates by the initiation of an electrical impulse. This electrical impulse starts in the SA node.
<h3>What is the Heart contraction?</h3>
Heart contraction may be defined as a type of physiological activity that stimulates electrical impulses which are initiated by the sinoatrial node. Systole is significantly the contraction phase of the cardiac cycle.
The SA node is a small bundle of specialized cells that is remarkably located in the right atrium. The electrical activity escalates through the walls of the atria and induces them to contract. This action finally forces blood into the ventricles.
Therefore, the SA node is responsible for the initiation of impulses that stimulates heart contraction.

The narrowing of mila's airways during an asthma attack affect resistance and airflow causes decrease in gas velocity, and airflow become increases airway resistance.
The lungs are designed as the body's center for gas inhaling and exhaling. Airway resistance is an essential parameter of lung function and results from the frictional forces of the airways, which oppose airflow.
Asthma develops due to chronic inflammation results in the airways smooth muscle, increased muscus production, and thickening of the lamina reticularis which is a layer of connective tissue that surrounds the airways.
The increased airways resistance associated with asthma is responsible for many sign and symptoms a patient will experience during as asthma, dyspnea, wheezing.
