It decreases
What happens to the air pressure inside your lungs when you inhale?
No
Yes
Does the nose trap dust and moisten the air?
Chest
Diaphragm
Biceps
Breathing process depends on which muscle
Exhaling, occurs when the diaphragm muscle relaxes which leads to decrease in size of chest
Exhaling
Decrease in  air pressure
Increase in air pressure
Inhaling
What leads to decrease in size of chest while exhaling
Exhaling
Inhaling
Sweating
Exhaling, or breathing out
What is happening when your chest decreases in size while breathing?
Digestive system
Respiratory System
The nose, diaphragm, lungs, and windpipe are all a part of what system in our body?
In the nose, mucus and hairs trap any dust or other particles in the air.  The air is also warmed and moistened
The exchange of gases takes place
Allows any dust
Mucus and hairs trap any dust or other particles in the air
Dust trap any mucus and hairs
What happens in the nose as air passes through to the lungs?

What happens to the air pressure inside the lungs when the diaphragm muscle tightens?
Lungs

The process of breathing depends on what muscle?
Decreasing blood pressure
Exhaling
By passing in urine
By exhaling through the nose
By keeping the air pressure in a constant level
How does air leave our lungs?
No
Yes
When you inhale, does air first go through your nose, then through your windpipe, and finally into your lungs?
Due to decreases in air pressure inside the lungs
Due to increase in air pressure inside the lungs
Chest muscle tightens
Inhaling occurs when the diaphragm muscle tightens which increases size of chest
Diaphragm muscle tightens
Why inhaling increases size of chest

What happens to the size of the chest when the diaphragm muscle relaxes?
Decreases in size
It increases
Increases in size

When you breathe in, what happens to the size of your chest?
To enter respiratory system
Due to increase in air pressure
To enter urinatory system
Exhaling decreases the size of your chest, which increases the air pressure inside your lungs, allowing for air to leave the lungs
Due to decrease in air pressure
When you exhale, why does air leave your lungs?
Exhaling
Blows air and gases to enter all the other parts of the body
Inhaling, or breathing in
Inhaling
Blows air and gases to enter the lungs
What is happening when your chest increases in size while breathing?
Breathing is the process of moving air into and out of the lungs. The process depends on a muscle called the diaphragm. This is a large, sheet-like muscle below the lungs. Inhaling, or breathing in, occurs when the diaphragm muscle tightens. This increases the size of the chest. This too decreases air pressure inside the lungs. This action allows air and gases to enter the lungs. Exhaling, or breathing out, occurs when the diaphragm muscle relaxes. This decreases the size of the chest. This increases air pressure inside the lungs. This action allows for air to leave the lungs. When you inhale, air enters the respiratory system through your nose and ends up in your lungs, where gas exchange with the blood takes place. What happens to the air along the way? In the nose, mucus and hairs trap any dust or other particles in the air. The air is also warmed and moistened. Next, air passes through a passageway that is connected to the windpipe. The air then finds its way to the lungs. In the chest, the windpipe splits so that air enters both the right and left lung.
