O2 pathway - Answer environment air --> lungs --> blood --> tissue --> mitochondria CO2 pathway - Answer mitochondria --> tissue --> blood --> lungs --> environment air external respiration - Answer exchange of gas between the air in the lungs and the blood gas transport by blood - Answer transport of oxygen to the body cells and the return of carbon dioxide internal respiration - Answer exchange of gases between blood and body cells cellular...

What are the steps of respiration? (following O2 and then following CO2) - Answer 1) O2 from Environment air to the lung 2) Transport of O2 from the lung to the blood 3) Transport of O2 from blood to the tissue 4) Transport of O2 from the tissue to the mitochondria where cellular respiration takes place -Following CO2 is just the exact opposite starting with the decarboxylation in the TCA cycle external respiration - Answer exchanging O2/CO2 between air in lungs and blood gas trans...

A heart attack that results in 30% damage to the left ventricle is difficult to survive because: a. the LV has a low amount of muscle mass to begin with and cannot sustain that level of damage b. that level of damage compromises blood supply to the lungs, resulting in asphyxia c. the loss of muscle power prevents the left AV valve from closing d. the LV needs all its muscle mass to pump blood effectively through the resistance of the systemic circulation e. the damage prevents the ventricu...

uvula - Answer what separates the nasopharynx from the laryngopharynx? -internal nares (2) -eustachian tubes (ear canals)(2) - Answer what are the two types (4 total) of openings in the nasopharynx? swallowing muscles - Answer what causes the epiglottis to fold over and cover the glottis? elastic connective tissue (ECT) at the glottis (air passing over causes them to vibrate) - Answer what are vocal cords and where are they found? -[mostly] *elastic connective tissue ...
