describe the diaphragm shape and location
thin, flat muscle between the thorax and the abdomen
what does the diaphragm connect
medulla (brain) by the phrenic nerve
what happens if the phrenic nerve snaps
you die
where does O2 go in inhalation
in
what happens to the diaphragm in inhalation
contracts and flattens
what happens to the ribs in inhalation
up and out
what happens to the chest cavities in inhalation
get larger
whats the name of the law used for respiratory
boyles law
what happens to the volume and pressure in inhalation
vol up, pressure down
where does O2 move to in the body in inhalation
lungs
where does CO2 go in exhalation
out
what happens to the diaphragm in exhalation
relaxes into an upside down U
what happens to the ribs in exhalation
intercostal muscles pull ribs together
what muscles pull the ribs together
intercostal muscles
what happens to the chest cavities in exhalation
smaller
what happens to volume and pressure in exhalation
volume down and pressure up
transportation of O2 formula
Hemiglobin+ O2 as- Oxyhemoglobin
hemoglobin formula
O2 +RBC= hemoglobin
function of hemoglobin
carry O2
what color is hemoglobin
red
what is oxyhemoglobin
a molecule
transportation of CO2 formula
CO2 +H2O= Bicarbonate ion (HCO3)
bicarbonate ion script formula
HCO3
