| ________ resp is the entrance of air into lungs and betwen blood and alveoli | External resp
🗑
|
||||
| ________ reso is between blood and cells | Internal resp
🗑
|

| annelids perform gas exchange by ____ through the skin | diffusion
🗑
|
||||
| Arthropods have ________ circ system no carriers for oxygen | open circ system
🗑
|
||||
| _______ the process which air is inhaled and exhaled | ventilation
🗑
|
||||
| inhalation the diaphragm __________ while intercostal muscles _______ and pushes the chest up | contracts and flattens; contracts
🗑
|
||||
| the increased vol in chest cavity _____ the pressure which makes the lungs expand and fill | reduces
🗑
|
||||
| exhalation is a ______ process | passive process
🗑
|
||||
| ____________ controls ventilation | medulla oblungato
🗑
|
||||
| Oxygen is transported almost entirely by | hemoglobbin
🗑
|
||||
| 1.5% of O2 is in | blood plasma
🗑
|
||||
| saturated hb has ____ O2 molecules | 4
🗑
|
||||
| oxygen binds to _______ in hb and CO2 binds to the _____ to form carbaminohemoglobin | heme grp; polyp chain
🗑
|
||||
| CO2is mainly transported as | carbonic acid
🗑
|
||||
| _____ of Co2 is carried as dissolved gas in the blood | 5%
🗑
|
||||
| ________ causes carbon dioxide loading | high Co2 in tissue fluid forms gradient between tissue fluid and blood. Co2 diffuses into blood
🗑
|
||||
| when ______ binds to oxyhemoglobin it causes it to lose affinity for O2 | H+
🗑
|
||||
| ________ causes oxygen unloading/ consumption | pressure gradient high O2 in artery and low O2 in tissue fluid
🗑
|
||||
| what is the Bohr effect | active tissues generate CO2 raising H+ (lowers pH)promotes oxygen unloading
🗑
|
||||
| heavy exercise raise CO2 lowers blood pH and lowers blood O2 which causes increased ventilation True/False | False, all values are constant
🗑
|
||||
| the main stimulus in pulmonary ventilation is the _______ conc in tissue fluid | H+
🗑
|
||||
| ____ is the driving force in respiration | PCO2 of arterial blood
🗑
