55
Q

what makes up the thoracic cage?

A

  2. ribs
  3. thoracic vertebrae
56
Q

what is the significance of the sternal angle

A

The sternal angle (also known as the Angle of Louis) is an important anatomical landmark for several reasons:

**1. Tracheal bifurcation: **It marks the point where the trachea divides (or bifurcates) into the right and left main bronchi, which are the large airways that lead into the lungs.
**2. Rib counting: **The sternal angle is in line with the second rib, making it a useful reference point for counting ribs during physical exams or medical procedures.

57
Q

what are the posterior throacic landmarks?what at

A
  1. vertebra prominens
  2. spinous processes
  3. interior border of the scapula
  4. 12th rib

  • Vertebra prominens: This is the most prominent bump at the base of the neck; (C7)
  • Inferior border of the scapula: The lower tip of the shoulder blade (scapula), which usually lies at the level of the 7th or 8th rib.
58
Q

What is the midclavicular line used for?

A

its a vertical reference line used to pinpoint findings on the chest

59
Q

what are the divisions of the thoracic cavity?

A
  1. Mediastinum:
  2. Pleural cavities:

  • Mediastinum: The central area of the thoracic cavity that contains the heart, great blood vessels, esophagus, trachea, and other structures.
  • Pleural cavities: Two spaces on either side of the mediastinum, each containing one lung, surrounded by a thin layer of pleura (a membrane that protects and cushions the lungs).
60
Q

Where is the apex of the lung located?

A

it extends slightly above the clavicle

61
Q

how many lobes does the R lung have?

A

3 lobes:
1. superior lobe
2. middle lobe
3. inferrior lobe

62
Q

what is an acinus?

A

the functional respiratory unit of the lung where gas exchange takes place

63
Q

mechanics of respiration:

what are the 4 major functions of the respiratory system?

A
  1. supplying o2
  2. removing co2
  3. maintaining acid-base balance
  4. maintaining heat exchange
64
Q

mechanics of respiration:

how is respiration controlled?

A

by
1. the respiratory center in the brainstem
2. humoral regulation (primarily by co2 levels)

65
Q

mechanics of respiration:

what is the main muscle of inspiration?

A

the diaphragm

66
Q

mechanics of respiration:

what happens during expiration?

A

the diaphragm & external intercostal muscles relax
= decreasing thoracic cavity volume + increasing intrathoracic pressure
= force air out of the lungs

67
Q

developmental competence:

why are infants vulnerable to respiratory problems?

A

they have smaller airways & less developed immune systems

68
Q

developmental competence:

how does pregnancy affect the respiratory system?

A
  • the diaphragm elevates
  • chest cage dimensions increase
  • breathing becomes deeper & more frequent
69
Q

developmental competence:

what are some age-related changes in the respiratory system of older adults?

A
  • decreased chest wall mobility
  • respiratory muscles strength decline
  • diminished lung elasticity
