Respiratory System

Question 1

Main functions

Answer 1

To bring 02 into blood
- All cells need 02 for engery

Take Co2 out of the body
Waste product

Question 2

3 stages

Answer 2

Breathing
Gaseous Exchange
Internal Respiration

Question 3

Pleural lining is

Answer 3

Membranes around lungs
Cushion so it protects
Has 2 layers
Fluid to stop friction

Question 4

Alveoli is

Answer 4

Tiny sacs
Walls are single cell thick
Stage 2 gaseous exchanged

Question 5

Intercostal muscles are

Answer 5

Between the ribs
- When it contracts - it lifts rib cage up and out
- when it relaxed - lowers rib cage down and in

Question 6

Diaphragm is

Answer 6

Large muscle
- Separates the chest from abdomen
- When relaxed it’s dome shaped contracts it then flattens
- lower ribs attached to the base of the lungs

Question 7

Pathway of inhaler air is

Answer 7

Nose
Pharynx (throat )
Larynx ( voice box )
Trachea ( windpipe)
Bronchi - beaches left and right
Bronchioles - smaller tubes
Alveoli - ball or sacks at end of bronchioles

Question 8

Diaphragm is

Answer 8

Large muscle
- Separates the chest from abdomen
- When relaxed it’s dome shape contracts and flattens

Question 9

Inhalation process

Answer 9

-Diaphragm flattens lungs lengthen
- intercostal contracts - rib cage lifts ( wider )
- pressure inside the lungs drops
- outside air pressure is not higher
- air flows into the lungs

Question 10

Exhalation process

Answer 10

• intercostals muslces relax ( rib cage drops )
• diaphragm relaxes back to dome shape ( lungs shorten )
• pressure inside the lungs is now higher than outside
• air moves out of the lungs

Question 11

Breathing stage 1

Answer 11

-Normal breath is 12-15 breaths per min
- air entering the lungs is - 21% oxygen
-.04% Co2
- air leaving lungs is - 15% oxygen and .4-% co2 leaving the body

Question 12

Diffusion stage 2 ( gassed exchange )

Answer 12

Diffusion - ( High concentrate to lower ) when gases move from a region of high concentration to one or lower concentrations or until equal

Question 13

Internal respiration stage 3

Answer 13

• takes place inside the cell ( muscles )
• capillary blood - high in 02 low in co2
  -02 in capillary moves into the muscle cells
• engery produced using 02
• C02 moves into capillary then back to heart via veins
  -Heart will pump blood back to the lungs to remove C02

Question 14

What is asthma

Answer 14

Long term lung disease that inflames and narrows the airways

Question 15

Causes of asthma

Answer 15

Wheezing
Chest tightness
Shortness of breath
Coughing late at night or early in morning
Dry weather cold frosty morning can make it worse

Question 16

Consideration towards asthmatic client

Answer 16

Seek medial advise
Do a gradual Warm up and extended cool down
Progress the program slowly
Careful or lying exercises ( dusty floors )
Environment
Always have inhalers with them
