Respiration Notes Flashcards
List the 5 functions of respiratory system
1) obtain oxygen
2) removes carbon dioxide
3) filter air
4) warms the air
5) moistens the air
Process of exchanging oxygen and carbon dioxide gases between the air and blood
Respiration
List the 5 parts of upper respiratory tract
1) nose
2) nasal cavity
3) sinuses
4) pharynx
5) larynx
List the 3 parts of lower respiratory tract
1) trachea
2) bronchial tree
3) lungs/alveoli
Purify air
Cilia
Tissue that divides nasal cavity in half
Septum
Sticky material that cleans and moistens air
Mucous layer
Small blood vessels that warm air
Capillaries
Hollow areas in skull that are overflow areas for mucous
Sinuses
Back of the nose mouth and throat
Pharynx
Makes air swirl
Nasal conchae
Voice box
Larynx
For protection in vocal cords
False on top
Makes sounds through vibrations in vocal cords
True lower
List the 6 parts of bronchial tree from largest to smallest
1) primary bronchi (1 rt, 1 left)
2) secondary bronchi (3 rt, 2 left)
3) tertiary bronchi
4) bronchioles
5) alveolar ducts
6) alveoli
Controls breathing
Diaphragm
List 3 steps of inspiration
1) rib cage moves up and out
2) diaphragm contracts and moves down
3) pressure in lungs decreases and air rushes in
List 3 steps of expiration
1) rib cage moves down and in
2) diaphragm releases and moves up
3) pressure in lungs increases, air pushes out
Protein in blood that carries oxygen throughout body
Hemoglobin
Nerve cells in blood vessels that detect the amount of oxygen in it
Chemoreceptors
List 9 steps of respiration
1) oxygen into lungs
2) oxygen into blood
3) blood to cells
4) oxygen into cells
5) cellular respiration
6) carbon dioxide into blood
7) blood to lungs
8) CO2 into lungs
9) CO2 leaves lung
Spasm of bronchioles
Asthma
Breakdown of alveoli due to toxins
Emphysema
Fluid in lungs
Pneumonia
Abnormal growth of cells
Lung cancer
Infection that causes swollen bronchi
Bronchitis
