Respiration System Flashcards
Oxyhemoglobin
combination of hemoglobin with oxygen
Lipoproteins
proteins that combine with and transport fat or other lipids in the blood plasma
Pleural lubricant
lubricant that is found in the pleural membrane to reduce friction from breathing
Carbonic acid
70% of CO2 is transported into carbonic acid then later on converted to bicarbonate
Bicarbonate
the product of carbonic acid in the body
since it’s too acidic
Chemoreceptors
nerves that test the amount of CO2 in the blood
Inspiration
1) intercostal Muscles contract, pulling ribs cage up and out
2) Diaphragm contracts and lowers ( flattens)
3) Abdominal muscles relax, diaphragm moves down
4) volume increases pressure decreases ( air rushes in)
Expiration
1) intercostal Muscles relax, ribcage falls down and moves in
2) Diaphragm relaxes and rises to original position
3) Abdominal muscles contacts pushing diaphragm up
4) volume decreases pressure increases ( air rushes out)
Tidal volume
Volume of air that can be inhaled and exhaled in a normal breath
Vital Capacity
Total volume of air that can be moved in and out of the lungs
Inspiratory reserve volume
Additional volume of air that can be take into the lungs
Expiratory reserve volume
Additional volume of air that can be forced out of lungs
Residual volume
Amount of air that remains in the lungs
Diffusion
movement of particles from an area of higher concentration to an area of lower concentration
Osmosis
movement of water molecules through a selectively permeable membrane from higher water concentration to a lower water concentration
