Respiratory System Flashcards
Spiracle (insect)
Mouth where air diffuses in
Insect’s Tracheal System (invaginated)
does not exert pressure/force for air to rush in like humans. Cannot breathe more unless more oxygen in the environment
Tracheal Tube (insect)
tube that delivers gas into body
Tracheole (insect)
where gas exchange happens, oxygen diffuses in and CO2 diffuses out
Operculum (fish)
bony covering over the fish
Gas exchange
is facilitated through wet respiratory surfaces
Hemoglobin
carries oxygen to red blood cells, when breathe, oxygen attaches to heme group
Nasal Cavity
humidity, heat, filtering
Lamella (fish)
discs where gas exchange happens
Gill Arch (fish)
has gill filaments (tail)) that increase SA:V
Countercurrent Exchange
guarantees diffusion happens all over. gas exchange
Pharynx
passage airway to trachea
Larynx
protect air way from food
Cilia
move mucus
Trachea
carry air in and out of lungs
Pleural Space
against ribs & lungs fo rlow frictioon for lungs to move freely
Bronchiole
transport air to alveoli
Alveoli
Gas exchange- expand to take in oxygen, compress to release carbon dioxide
Body Surface (worms)
oxygen & carbon dioxide exchange thru the skin
Diaphragm
contracts and moves down to pull air up
Invagination - lungs
bring air in, extract o2 and release
Intercostal Muscle
pulls up when diaphragm goes down
Evagination (gills)
gills go into water, water does not go into gills
