Flashcards in Lecture 6 (Respiratory System) Deck (20):
1

Functions of respiratory system

get oxygen and release CO2
smell more efficiently when you take a deeper breath
deep breath
Bear down on the abdomen (Urinary, bowels and baby delivery)
Cough and sneeze release of air
Alcohol is released by air

2

Nasal Cavity

Lined with pseduostratifed cilitated columnar epithelium
Cools the air, moisten when dry, warm the air, trap particles
Mouth does none of these
Nerve endings help us smell

3

Sinuses

Connect to the nasal cavity, drain into the nose
Risk of infection because the blood does not reach these areas easily

4

Mouth

Stratified squamose eiptheal

5

Larynx cancer

Ppl that smoke tobacco, related to hot smoke
Drinking and smoking increases this risk even more than the two seperately

6

Laryngitis

Inflammation of larynx

7

Puberty

Causes thyroid cartilage
Vocal chords in boys become thicker and longer
Vocal chords in girls, short

8

Tracheitis and bronchitits

Inflammation

9

Neck injury

Can collapse the apex of the lung

10

Pleuritis

Inflammation of pleura

11

Indentation of the left lung

the aorta

12

indentation of the right lung

the esphoagus

13

Pulmonary surfactant

Produce and secreted when 8 months/ birth
Lowers surface tension of the aveoli so they inflate
Insufficient surfactant = respiratory distress in premature children

14

Hiccup

Irritation of nerves in the diaphram, contracting the diaphram out of sequence

15

Pneumonia

Diff kinds
Bacterial, viral, fungal
Infections of the lung
death in elderly
Blood will back up in the lungs and infection occurs
Stroke makes you more vulnerable to pnuomia
Blood and mucus fluid in the lungs

16

Tuberculosis

Bacterial
some a resistant to drugs
bacteria can leave lungs and circulate body, go into the bones or kidney

17

Asbestosis

Inflammation when breathing in fibers of asbestos insulation

18

Emphysema

Lung loses elasticity
Barrel chest, deep breath and the lung get stuck
Inflammation in bronchial and this = COPD, chronic obstructive pulmonary disease

19

SIDs (Up to the first year)

sudden infant death syndrome
Typically die in crib
Not enough surfactant as they get older the lung fails

20

Allergies and Asthma

Airway are too small and bronchial contact too much
Medicine allows airways to open
