Respiratory system Flashcards
what is the process of inhalation
- when you inhale the diaphram contracts and shortens/flattens the muscle
- external intercoastle muscle between each rib
- the process actas to increase the volume of the thoracid cavity which decreases pressure
what is the process of exhalation
diaphram relaxes
-intercostal muscle contraxts ribcage in and out
decreases volume and increases pressure
what is a respitory surface
-it has to be large enough for gas exchange
-the outer skin is used for gas exchange and the diffusion transports oxgygen, carbon dioxcide in and out from blood
what is gas exchange
-process which diffues into the cells and carbon dioxcide diffues
what is ventalation
-moving all the oxygen rich air to the lungs and carbon dioxcide
what is a diaphram
- sheets of muscle that seperates the thoracic cavity frpm the abdominal cavaity
gills
respitory surfaces
- folds in the body that increases. surface area
- diffusion transports gasses to blood cells
- all gills breathers in all aquatic enviorment
aquatic gas exchange
-takes water into mouth. ventatilating it out the gills
Tracheal System
-insect gas exchange
the trachea internal system
what are the lungs
- contain sacs with moist surface blood transports gasses to cells by diffusion
alveoli
-made up of warm moist thin membrane allows easy diffusion of gasses across the membrane into the blood
large number of alveoli allowd for maxium surface area for gas exchange
what is pneumia
-inflammitory fluid that fills the alveoli interfers with gas exchange
what does pneumia cause
- bacterial infection
treatment for pneumia
-antibiotics, vaccine
cystic fibrosis
- cell relases thick sticky mucus that clogs lungs causing difficulty breathing trapped bacteria can cause infections
