Anatomy

Question 1

Nasal Cavity

Answer 1

Functions to humidify, warm, filter and act as a conduit for inspired air as well as protect the respiratory tract through the use of the mucociliary system.

Question 2

Nose

Answer 2

Allows air to enter body then filters debris and warms and moistens the air.

Gives a sense of smell.

Question 3

Adenoids

Answer 3

Help keep the body healthy by trapping harmful bacteria and viruses that we breathe in or swallow.

Question 4

Tonsils

Answer 4

Help filter out germs that enter through the nose or mouth to protect the rest of the body from infection.

Question 5

Epiglottis

Answer 5

Small, leaf-shaped sheet of elastic cartilage that protects the larynx (voice box) and helps with swallowing.

Question 6

Larynx

Answer 6

A hollow tube that helps move air from the nose and mouth to the lungs.

Located at the upper opening of the trachea (windpipe), which is the passageway to the lungs.

Question 7

Pharynx

Answer 7

Commonly called the throat.

Passageway in the head and neck that is part of digestive system and respiratory system.

Connects the nose, mouth, and throat to each other.

Question 8

Trachea

Answer 8

Main function to carry air in and out of the lungs.

Stiff and flexible tube, provide a reliable pathway for oxygen to enter the body.

Question 9

Pleura

Answer 9

Allows for easy movement of the lungs and inflation during breathing.

Covers the lungs.

Question 10

Pleural Space

Answer 10

Space between the visceral and parietal pleura.

The space contains a tiny amount of serous fluid that lubricates the pleural surface and makes it easy for them to slide over each other during lung inflation and deflation.

Question 11

Lung

Answer 11

Function of the lung is to get oxygen from the air to the blood, performed by the alveoli.

Question 12

Alveoli (Air sacs)

Answer 12

Very small air sacs where the exchange of oxygen and carbon dioxide takes place.

Question 13

Capillaries

Answer 13

Are blood vessels in the walls of the alveoli. Blood passes through the capillaries, entering through the pulmonary artery and leaving through the pulmonary vein.

Question 14

Bronchial Tubes

Answer 14

Let air in and out of the lungs for breathing. (Air comes from the nose or mouth into the trachea and then passes through the bronchial tubes).

Sometimes referred to as bronchi or airways.

Question 15

Bronchiole

Answer 15

Deliver air to alveoli in the lungs.

When breathing, oxygenated air is pulled into the bronchioles.

CO2 collected by the alveoli is released from the lungs as exhalation.

Question 16

Diaphragm

Answer 16

Diaphragm contracts and flattens and the chest cavity enlarges during inhalation.

This contraction creates a vacuum, which pulls air into the lungs.

During exhalation, the diaphragm relaxes and returns to its domelike shape and air is forced out of the lungs.
