Q

Type II Aveolar Cells

A

Separate alveolar fluid that coats inner lining of alveolus

Makes surfactant

17
Q

Surfactant

A

Function is to decrease surface tension of alveolar fluid

18
Q

Respiratory Distress Syndrome

A

Breathing disorder of premature infants

Do not make surfactant

19
Q

Muscles of Inhalation (@ REST)

A

Active Process; contraction of diaphragm (move 0.4 in) and external intercostals
0.5L air

20
Q

Muscles of Inhalation (W/ EXERCISE)

A

Diaphragm (moves 4 in), External intercostals, and sternocleidomastoid
2-3L air

21
Q

Muscles of Exhalation (@ REST)

A

Passive process; relying of relaxation of diahragm and external intercostals
Pushes CO2 out of lungs

22
Q

Muscles of Exhalation (W/ EXERCISE)

A

Active proces; contraction of internal intercostals and rectum abdominus

23
Q

Diaphragm (@ REST)

A

1st P = ATM
Aveolar = ATM
Intrapleural = Subatomic
Result = no air flow

24
Q

Inhalation (@ REST)

A

1st P = ATM
Aveolar = Increase ATM
Intrapleural = Decrease ATM
Result = Air enters system

25
Q

Exhalation (@ REST)

A

1st P = ATM
Aveolar = Increase ATM
Intrapleural = Subatomic
Result = Drive CO2 out of lung

26
Q

Pulmonary Ventilation

A

PO2 Outside > PO2 Inside Alveoli

27
Q

External Pulmonary Respiration

A

Convert dexoy blood -> Oxygen blood

PO2 in alveolus > PO2 in dexoy blood

28
Q

Internal Tissue Respiration

A

Oxygenated blood needs to release O2 from hemoglobin

PO2 in O2 Blood > PO2 in tissue

29
Q

Factors for O2-Hb disassociation

A
  1. H+ increase: Structural change
  2. CO2: Binds to globin of Hb
  3. Heat: change Hb molecule to dissociate
