3 major parts of the respitory system
Airway-carry oxygen to lungs and co2 to be expelled with help of difram
-nose
-mouth
-pharynx
-larynx
-trachea
-bronchi
-bronchioles
Lungs
Muscles or respiration
Function of the human respiratory system
to transport air into the lungs to facilitate diffusion of oxygen into the blood stream to receive the wast product carbon dioxide from the blood and to exhale the carbon dioxide
components of the respitory system
nose
tongue
pharnx
larynx
trachea
lung
bonchi
bronchioles
cappilaries
alveoli
How the respitory system works in relation to skeleton and muscular systems
Impulse sent from brain
l
impulse received by the muscles of the ribs and chest
l
muscles of the ribs and chest contract
l
ribs pull upwards and outwards
l
air rushes into the lungs
relaxation of the diafram
l
ribs and chest lower
l
squeezing air out of lings
Equation for air venillatin in 1 min
12 breaths X 0.5L = 6L ventilate/min
inspiration
Breathing air into lungs
Gaseous exchange (difsion)
when the carbon dioxide moves from the blood into the alveoli at the same time that oxygen moves in the opposite direction.
function of the respiratory system
works with the cardiovascular system to transport oxygen to every cell of the body and to remove carbon dioxide
Vo2 max
the ability to use oxygen efficently is now and measure as a maximal oxygen uptake
Lungs
facilitate gas excahnge
Trachea
the windpipe (tube) which connects voice box to bronchi
Pharynx
connecting passage for air from nose and mouth to larynx
throat divided into 3 parts
Larynx
controls the airflow to the trachea
Bronchi
Distribute air into each lung
Bronchioles
to bring air to the alveoli for gas exchange
Alveoli
to facilitate the exchange of carbon dioxide and oxogen
Mouth nose and nasal cavity
entry and exit points for air and mosturising it
cilia
hair like structures that filters the air
tongue
keeps airway open
