respiration and gas exchange Flashcards
aerobic respiration
is a chemical reaction that take place inside the mitochondria which use oxygen to break down glucose to release energy
anaerobic respiration
chemical reactions in cells that break down nutrient molecules to release energy
gas exchange
the diffusion of oxygen and carbon dioxide into and out of the body
gas exchange surface
a part of the body where gas exchange between the body and the environment takes place
alveoli
tiny air sacs in the lungs where gas exchange takes places
trachea
a tube through which air travels to the lungs
goblet cells
cells found in the lining of the respiratory passages and digestive system which secrete muc
cilia
tiny projections from some of the cells in the lining of the respiratory system passages
thorax
the chest part of the body from the neck down to the diaphragm
bronchus
one of the two tubes that takes air from the trachea to the lungs
bronchiole
a small tube that takes air from a bronchus to every part of the lungs
ventilation
the movement of air into and out of the lungs by breathing movements
intercostal muscles
muscles between the ribs which raise the lower rib cage when they contract and relax
