Food passes through several structures in the digestive system, starting with the mouth where it is chewed and mixed with saliva. It then travels down the esophagus to the stomach, where it is further broken down by stomach acid and enzymes. The partially digested food then moves to the small intestine, where nutrients are absorbed, and finally to the large intestine for water absorption before waste is excreted.
Once you enter food through your mouth, it travels down the esophagus into the stomach. In the stomach, the food is mixed with digestive acids and enzymes to break it down. From the stomach, the partially digested food moves into the small intestine where nutrients are absorbed into the bloodstream. The remaining waste then travels to the large intestine and is eventually passed out of the body as stool.
Water moves through biosphere. It travels through land, water and air.
Unwanted waste enters the digestive system through the mouth, travels through the esophagus to the stomach, then to the small intestine where nutrients are absorbed. The remaining waste moves to the large intestine, where water is absorbed and solid waste is formed. Finally, the waste is expelled through the anus in a process known as defecation.
The food starts in the mouth, travels down the esophagus to the stomach, travels from the stomach to the small intestine, travels then to to large intestine, and exits the body through the rectum then the anus.
The material through which a wave moves is called the medium. It can be solid, liquid, or gas, and the properties of the medium affect how the wave behaves and travels.
After the mouth, food travels down the esophagus to the stomach. From there, it moves to the small intestine where nutrients are absorbed, and then to the large intestine where water is absorbed before waste is excreted.
Warm and wet air does move through both mouth and nose. You can shut your mouth and air will just come from the nose.
Which one of the following correctly represents the order in which food coming into the body passes through the structures of the digestive system? Food moves from the mouth to the pharynx, then on to the esophagus, the stomach, the small intestine, and finally the large intestine.
Light travels through space and does not fall to Earth. It moves in a straight line, following the laws of physics, and does not get pulled down by gravity like objects with mass do.
A molecule of oxygen enters the body through the nose or mouth, travels down the trachea, passes through the bronchi and bronchioles, and finally reaches the alveoli in the lungs where oxygen diffuses into the bloodstream through the thin walls of the alveoli.
