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.

Molecules from food and molecules of oxygen move from the mouth and the nose to the cells of the body through a series of blood vessels, including veins, arteries, and microscopically small blood vessels (capillaries), that extend throughout the body is option A.

How do oxygen molecules move to cells of the body?

  • The oxygen enters the circulation via the alveoli, which are small sacs in the lungs where gas exchange occurs. Simple diffusion is used to transport oxygen into circulation.
  • The oxygen-rich blood flows back to the heart.
  • After then, oxygen-rich blood is pushed through the aorta, a major artery that gets blood straight from the heart.
  • Oxygen-rich blood flows from the aorta through the smaller arteries and, eventually, to the capillaries, the smallest form of the blood vessel.
  • Diffusion transports oxygen molecules from the capillaries to the bodily cells.

How does food move to cells of the body?

  • The circulatory system is one of the human body's eleven organ systems. Its primary job is to transfer nutrients to and waste away from cells.
  • The hepatic portal vein transports nutrients ingested in the small intestine to the liver.
  • Nutrients move from the liver to the heart via the inferior vena cava blood channel.
  • The heart forces nutrient-rich blood to the lungs, where it picks up oxygen, and then to all other cells in the body.

Thus, the correct option is A.
