Q

What is the Respiratory system?

A

The parts of the respiratory system controls breathing rate via the intake of oxygen and exit of carbon dioxide.

Q

What is the Alveoli?

A

Small sacs at the end of the broncioles that allow for the exchange of carbon dioxide and oxygen.

Q

What is the Epiglottis?

A

Flap at the back of the throat that prevents food from entering the trachea to ensure only air gets into the trachea.

Q

What are Bronchioles?

A

Smaller airways in the lungs that form when the bronchi further divides. They carry the air to the alveoli.

Q

Nasal Cavity

A

Primary entrance for air to enter the respiratory system, where the air is filtered and warmed before the air is transportated to the lungs.

Q

What is the Pharynx?

A

Also known as the throat, it allows air to pass into the lungs and the larynx, and food and liquids to pass into the esophagus.

Q

Respiratory System Sequence

A
  1. Air enters the mouth and nasal cavity where it is warmed and filtered.
  2. Pharynx
  3. Epiglotus separates food and air into the esophagus or trachea, respectively.
  4. The larynx opens to the trachea. This is also the voice box.
  5. The trachea is the passage that allows air to travel to the lungs.
  6. Broncus, branches the trachea off the left and right lung
  7. Bronchioles
  8. Alveoli, the site of gas exchange

Q

Systems of Interactions

How does the respiratory system interact with the circulatory system.

A

When red blood cells move into the lungs via the pulmonary arteries, they take in the oxygen, carrying it to the rest of the body, later on. They also remove carbon dioxide from the body.

Q

How does gas exchange work?

A

The process where oxygen travels across the alveoli into the red blood cells, and carbon dioxide from the RBCs to the alveoli. This is done because capillaries in the lung are wrap around the alveoli.

Q

Exhalation?

A

The process where the ribs move in and down, voume decreases, pressure increases, and the air moves out.

Q

Inhalation

A

The process where the ribs move up and out, volume increases (sucking the air in), pressure in the lungs decrease, and air enters the lung to equalize the pressure.

Q

What is the diaphragm?

A

A sheet of muscle slung underneath the lungs that contracts and relaxes to change air pressure during breathing.

17
Q

Intercostal Muscles

A

The muscles between the ribs that help change internal pressure by lifting and relaxing the ribcage.

18
Q

Ciliated cells

A

Cells that sweep mucus up and out of the airways, carrying any debris that stuck to it.

19
Q

What are goblet cells?

A

Goblet cells secrete mucus, forming a protective blanket over the tops of ciliated cells.

20
Q

Mucus

A

A protective secretion produced by goblet cells that traps debris in the respiratory system.

21
Q

Bone Marrow

A

Tissue inside bones where red blood cells are made.
