Q

Internal respiration

A

Gas exchange at the tissues
O2 goes out from the blood into tissues, CO2 goes into the blood from the tissues
O2 needed to produce ATP

A

The initial portion of the nose
where we see the little hairs
Lines with stratifies squamous to protect again abrasion

16
Q

Inferior conchae function

A

Prevents drying out

Venus plexus engorges with blood and swells preventing air from flowing through that side of the nasal cavity

17
Q

Posterior nasal aperture

A

End of the nasal cavity

Air moves into the pharynx

18
Q

Pharynx

A

Muscular funnel extending 5 inches from choanae to the larynx

19
Q

3 regions of the pharynx

A

Nasopharynx
Oropharynx
Laryngopharynx

20
Q

Nasopharynx

A 
Most superior
Respiratory mucosa, ciliated pseudostratified columni
Pharyngeal tonsils
Pharingo tympanic tube
Soft palate
21
Q

Oropharynx

A

Behind the mouth
Food also passes through here
Stratified squamous epithelium
Ends where epiglottis starts

22
Q

Laryngopharynx

A

Stratified squamous epithelium
Air will go anterior side into the respiratory tract
If food it will go posterior into esophagus

23
Q

Larynx cartilage

A

-Big unpaired cartilage
Thyroid hyaline cartilage (anterior-shield)
Cricoid hyaline cartilage (ring-like, goes around)
Epiglottis elastic cartilage
-Small paired cartilages: (attached to vocal cords which produce frequency)
Corniculate cartilage (tip of structure)
Arytenoid cartilage (The body that leads to the tip)
Qubi form cartilage (we can’t see them) Support soft tissue in the larynx

24
Q

Muscles of the larynx

A

Intristic: Vocalization
Extrinsic: Larynx up when we swallow, makes epiglottis closes

25
Q

Trachea

A

-Tube that extends from the larynx to bronchi
-Multiple C-shape hyaline cartilage rings to prevent trachea from collapsing
Ciliated pseudostratified columnar epithelium

26
Q

Muco ciliated elevator

A

In the trachea, it pushes mucus back into the larynx

27
Q

Carina

A

The internal ridge that splits the trachea into bronchi

28
Q

Bronchial tree

A

Right side: 3 lobar bronchi
Left side: 2 lobar bronchi
They continue to split from lobar bronchi to segmental bronchi,
to bronchioles, to terminal bronchioles, respiratory bronchioles,
to alveolar ducts and finally alveolar sacs. From there it goes to the atrium

29
Q

Lungs

A

Organ where gas exchange happens
Right lung has 3 lobes
The left side has 2 lobes

30
Q

Right Lung

A

Divided by horizontal fissure which divides superior and middle lobe
Oblique fissure divided middle and inferior lobe

31
Q

Left Lung

A

Two lobes dived by oblique fissures

32
Q

Pleurae

A

The serous lining around the lung.
Helps us breathe by allowing lungs to expand
Visceral: directly on the lungs
Parietal: Inner lining of the ribcage
Pleural cavity: potential space, pleural fluid

33
Q

Helom

A

Where things go in and out of that organ
