How do molecules from food and molecules of oxygen that enter the body through the mouth and the nose move to cells of the body?
SC.6.L.14.5 A. Molecules from food and molecules of oxygen move from the mouth and the nose to
cells of the body through a series of blood vessels, including veins, arteries, and
microscopically small blood vessels (capillaries), that extend throughout the body.
B. Molecules from food and molecules of oxygen move from the nose and the mouth to
cells of the body through special respiratory and digestive tubes that directly connect
the lungs and stomach to the rest of the body.
C. Molecules from food and molecules of oxygen move from the mouth and the nose to
cells of the body through special respiratory and digestive tubes that directly connect
the mouth and nose to the rest of the body.
D. Molecules from food and molecules of oxygen do not move from the mouth and the
nose to cells of the body. Oxygen is breathed in and out of the lungs without entering
the cells of the body, and molecules from food enter the digestive tract and pass
through the body without entering cells of the body.
