Inhalation

O2 goes inside lungs, from bronchiole to alveoli

The alveoli passes O2 to bloodstream

Eritrocytes use Fe in Hemoglobine to carry O2 to cells

Oxigenated blood arrives to left atrium, then to left ventriculum

Ventriculum pumps the blood into the rest of the body

Eating

Chewing, along with enzimes in saliva break down food a bit

Gastric acid in stomach helps even more to turn polysacharides into monosacharides

Enterytrocite cells, which make up villus in intestine, pass these molecules to bloodstream

Glucose is transported trough blood

Insulin, produced in pancreas, helps glucose pass trough the cell membrane to enter the cell

(In the cytoplasm)

glycolisis occurs

(formula)

O2 goes into cell to pick up waste from cell respiration

(if there's oxygen available) Krebs cycle ocurrs (in the mithocondria)

Electron transport chain happens (in mithocondirial membrane)

(formula)

H produced in the process bonds with O2 to form H2O, H is desaturized that way
