Oxygen diffuses from the alveoli into surrounding capillaries. Oxygen diffuses from the alveoli into surrounding capillaries. Oxygen is carried through blood vessels to a capillary. Oxygen is carried through blood vessels to a capillary. Oxygen diffuses from the blood to the body's tissues. Oxygen diffuses from the blood to the body's tissues. Oxygen binds to a molecule of hemoglobin. Oxygen binds to a molecule of hemoglobin. Oxygen enters a red blood cell. Oxygen enters a red blood cell.

The oxygen enters the bloodstream from the alveoli, tiny sacs in the lungs where gas exchange takes place (Figure below). The transfer of oxygen into the blood is through simple diffusion. ... While oxygen moves from the capillaries and into body cells, carbon dioxide moves from the cells into the capillaries.

Explanation:

hello there,

igneous rock formed from below the surface would have more crystals because

answer: because magma cools more slowly than lava

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
