Q

3 functions of the larynx

A

23
Q

Trachea function

A
  1. Provides passageway for air to reach the lungs

2. Filters air and propels mucus to the throat and away from the lungs

24
Q

Bronchi

A

Formed as the trachea branches off into a left and right branch

25
Q

Visceral pleural layer

A

Located closest to the lungs

26
Q

Parietal pleural layer

A

Outermost membrane of the lungs

27
Q

Pleural space

A

Region between the visceral and parietal membrane

28
Q

Why is the pleural space important to respiration?

A

The pleural space maintains a negative pressure that allows the lungs to stay inflated between breaths

29
Q

Divisions of the lungs

A

Left lung contains 2 lobes (superior and inferior) and right lung contains 3 lobes (superior, medial, and inferior)

30
Q

Bronchioles

A

Smaller divisions of the bronchi

31
Q

Alveoli

A

The air sacs that form off of the bronchioles. Location for gas exchange with atmosphere. (Each surrounded by a capillary bed)

32
Q

Why are the alveoli such important structures in the lungs?

A

The only place gas exchange occurs with atmospheric air

33
Q

Cells found in the alveoli

A

Cuboidal cells function: to produce a lipid called surfactant

34
Q

Importance of surfactant

A

Lowers the surface tension in the lungs and keeps the alveoli from collapsing between breaths

35
Q

Macrophages

A

Immune system cells that patrol the lungs and destroy pathogens

36
Q

4 phases of the respiratory cycle

A
  1. Pulmonary Ventilation
  2. External Respiration
  3. Respiratory gas transport
  4. Internal Respiration
37
Q

Pulmonary Ventilation

A

The process of moving air into and out of the lungs (breathing)

38
Q

Inspiration

A

Movement of air INTO the lungs

39
Q

Expiration

A

Movement of air OUT of the lungs

40
Q

Muscles involved in Respiration

A
  1. Diaphragm

2. Intercostals of the rib cage

41
Q

External Respiration

A

Gas exchange inside the lungs (occurs due to concentration differences)

42
Q

Oxygen transport

A

Oxygen diffuses into the blood and attaches to hemoglobin forming oxyhemoglobin

43
Q

Carbon dioxide transport

A

Carbon dioxide diffuses into the blood and is converted into a bicarbonate ion

44
Q

What type of cartilage forms the epiglottis?

A

Elastic cartilage

45
Q

What type of cartilage forms the other 8 laryngeal cartilages?

A

Hyaline cartilage

46
Q

Smallest conduction respiratory passageways

A

Bronchioles

47
Q

Separates the oral and nasal cavities

A

Palate

48
Q

Food passageway posterior to the trachea

A

Esophagus

49
Q

Closes off the larynx during swallowing

A

Epiglottis

50
Q

Windpipe

A

Trachea

51
Q

Actual site of gas exchanges

A

Alveoli

52
Q

Pleural layer covering the thorax walls

A

Parietal pleura

53
Q

Pleural layer covering the lungs

A

Visceral pleura

54
Q

Opening between vocal folds

A

Glottis

55
Q

Fleshy lobes in the nasal cavity which increase its surface area

A

Conchae

56
Q

Vibrate with expired air

A

Vocal cords
