What is it important that carbon is recycled?

Answers

It's not so important that it be recycled ... after all, there's almost a limitless supply,
and there's no danger of ever running out of it.

What's important is to keep carbon out of the atmosphere. In order to do that, we
need to reduce the amount of it that's released during so many of the processes
that we've been doing on a huge scale for the past 200 years, and invent ways
to capture the carbon that we DO continue to release, before it gets into the
atmosphere.

During inhalation, air continues to move into the lungs until:_____A) the internal pressure is the same is atmospheric pressure.
B) the internal pressure is less than atmospheric pressure.
C) the internal pressure is greater than atmospheric pressure.
D) the compliance of the lung decreases.
E) the lungs recoil.

Answers

Answer:

(B) the internal pressure is less than atmospheric pressure.

Explanation:

The process of respiration is divided into two distinct phases, inspiration (inhalation) and expiration (exhalation). During inspiration, the diaphragm contracts and pulls downward while the muscles between the ribs contract and pull upward. This increases the size of the thoracic cavity and decreases the pressure inside. As a result, air rushes in and fills the lungs.

Hence, as the thoracic cavity increases in volume the lungs are pulled from all sides to expand, causing a drop in the pressure (a partial vacuum) within the lung itself. As such the internal pressure is less than atmospheric pressure.

During expiration, diaphragm contracts inferiorly and thoracic muscles pull the chest wall outwardly (the diaphragm relaxes, and the volume of the thoracic cavity decreases, while the pressure within it increases). As a result, the lungs contract and air is forced out.

During inhalation, air continues to move into the lungs until the internal pressure is the same is atmospheric pressure. Correct option is A.

During inhalation (inspiration), the diaphragm and other respiratory muscles contract, expanding the thoracic cavity. This expansion increases the volume of the lungs, leading to a decrease in the internal pressure within the lungs. As a result, the air from the surrounding atmosphere (which has higher pressure) flows into the lungs, filling them with fresh oxygen. Inhalation continues until the internal pressure in the lungs equals the atmospheric pressure, at which point the flow of air stops, and the lungs are filled with the appropriate amount of air for that particular breath. This process is essential for proper gas exchange, where oxygen is taken into the bloodstream and carbon dioxide is expelled from the body during exhalation (expiration).
