Answer:
TRUE
Explanation:
No biological system is completely closed.
A nutrient cycle is the movement and exchange of both organic and inorganic matter back into the production of matter. This cycle is a recycling system which always occurs no matter what.
In a system that looks closed (closed loop), nutrients may be limited because they are not cycled through the system fast enough and/or it is not possible to compensate for deficiencies by migration.

Explanation:
Air that enters the pleural space during inspiration but is unable to exit during expiration creates a condition called Pneumothorax.
<h3>What is Pneumothorax?</h3>
An abnormal buildup of air in the pleural space between the lung and the chest wall is known as a pneumothorax. Shortness of breath and quick, acute, one-sided chest discomfort are common symptoms . A tension pneumothorax happens when an area of injured tissue forms a one-way valve, increasing the amount of air in the gap between the chest wall and the lungs. As a result, there may be an oxygen deficiency that worsens with time and low blood pressure. Obstructive shock is a type of shock that results from this and can be lethal if left untreated. A pneumothorax can very infrequently affect both lungs. Although the term "collapsed lung" can also refer to atelectasis, it is frequently used to describe it.
