Respiratory system

What are the two components to respiration

inhale and exhale

What do we inhale?

Oxygen

What do we exhale

Carbon dioxide/carbonite

What exchanges the oxygen with the carbon dioxide

alveoli

What is Respiration

It is the exhange of the gases

Gas exchange

the internal respiration through the blood and cells

Upper respiratory tract includes what?

Nose, nasal cavity, paranasal sinuses, the pharynx

Lower respiratory tract includes what?

Larynx and the lungs

What is used interchangeably with the throat?

The pharynx

What is used interchangeably with the voice box?

The larynx

Where is the nasopharynx located?

The nose

Where is the oral pharynx located?

The mouth

Where is the laryngeal pharynx located?

In the larynx

Where are the vocal cords?

In the layrnx

What does the cartilage in the trachea do?

It helps hold it open so it does not collapse

What does the epiglottis do?

It helps to keep food from going in the airway

Why does the epiglottis need to close?

So you don’t aspirate

What protects you from getting aspiration pneumonia?

The epiglottis

Which lung has three lobes?

The right lung

Which lung has two lobes?

The left lung

Why does the left side of the lung only have two lobes?

The heart

What do alveolar macrophages do?

Where is the apex

The top of the lung

What is the bottom of the lung called

The base

Where is the visceral pleura?

It is next to the lung

Where is the parietal pleura?

Outside of the lung

Why do we need fluid in the pleural space?

What two cavities does the diaphragm separate

Abdominal and thoracic

What happens to the diaphragm when you inhale

It will contract and pull down

What does the intercostal muscles do

It helps to bring the ribs out so we can get a full breath

What is euphea

It is a normal breath

What is hyperpnea

It is a forced breath

What is atmospheric pressure

It is when there is a negative respiratory pressure

What is absolute pressure

There is zero respiratory pressures equal to the atmospheric pressure

What does surfactant do?

It allows alveoli to expand and close

What is a spirometry

It is a machine that can tell the lung capacity

What happens when you have low hemoglobin?

It makes it hard to breath

What binds to hemoglobin?

IronW

Where would you find the intercostal nerves

In the initercostal muscle

What is apnea

No breathing

What is hyperventilation

Fast breathing

What is dyspnea

Disfunction of the lungs
