During exhalation, the diaphragm and intercostal muscles relax, causing the chest cavity to decrease in size. This increases the pressure in the lungs, pushing air out of the lungs.
the diaphragm contracts and moves downward, and the rib cage moves upward and outward.

What are the three phases of breathing?
The three phases of breathing are:The Active phase which is known as (inhalation/ inspiration).Phase 2. gas exchange in the lungs also known as (Internal exchange).The Passive phase which is known as (exhalation /expiration).
When the physical state of a substance changes during a phase what happens to the temperature of the system?
The temperature remain constant during a change of phase.
What happens during g phase?
Chromosomes Are Checced for errors
What happens in the lag phase of bacterial growth?
Bacteria grow most rapidly during the log phase.
Inhalation is active phase of breathing?
Actually, inhalation is considered a passive process because it is driven by the contraction of the diaphragm and the external intercostal muscles. These contractions create a negative pressure in the chest cavity, allowing air to be pulled into the lungs. Exhalation, on the other hand, is considered an active process, involving the relaxation of these muscles to push air out of the lungs.
What happens during exhalation phase of breathing?
Exhaling is expelling used air from the lungs. During exhalation,the diaphragm moves upward while the rib cage moves downward so it goes back to its dome-shaped position
What happens during the exhalation phase breathing?

Which phase of breathing inhalation or exhalation is considered active and passive?
Inhalation is an active process and exhalation is a passive process

What happens during inhalation phase of breathing?
Pressure within the thorax decreases and air is drawn into the lungs
What phase happens during mitosis?
Prophase.
What happens s?
DNA replication happens during s-phase.
What happens the temperature during a phase change?
nothing
What step in ventilation requires muscle work?
The inhalation phase. During the inhalation phase, the diaphragm contracts and this requires energy expenditure. The exhalation phase, on the other hand, only involves passive muscle recoil of the diaphragm and does not require work or energy.
What happens during the conditioning phase of laser printing?
What happens during the conditioning phase is as follows. A uniform -600 volt charge is placed on the photoelectric drum by the Primary corona.
What can no occur during pro phase 2 that happens in pro phase 1?
Crossing-over
What happens to the energy during a phase change?
When energy is added during a phase change the energy is used to break molecular bonds.
