The food first enters your mouth, then travels down you esophagus. Then it enters your stomach where it is broken down farther. Then it travels through the duodenum, through your small intestines, through your large intestines. If then goes through your colon, solid waste leaves your body by way of the anus.
Orbit is the path that a body follows as it travels around another body in space.
Orbit is the path
An orbit.
The path that blood travels through is called the circulatory system. It includes the heart, blood vessels (arteries, veins, capillaries), and blood, which is pumped by the heart to deliver nutrients and oxygen to cells throughout the body and remove waste products.
It is an orbit.
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.
Orbit
Light always takes the shortest path possible through any medium. As such, when it travels through a vacuum, it travels in a straight line (no refraction). When it travels through the air, the molecules in the air scatter it very slightly, causing some diffusion and refraction, depending on the composition of the air through which it passes. When it travels through water, the shortest path through that medium is not a straight, collinear line from the point of incidence...it is actually offset by a small angle (the angle of refraction). The bent path that light takes through water or another substance is actually the shortest path available to it through that medium.
Air enters the body through the mouth or nose, travels down the trachea, passes through the bronchial tubes in the lungs, and finally reaches the alveoli where oxygen is absorbed into the bloodstream and carbon dioxide is released. This process allows for gas exchange to occur in the lungs.
An orbit.
the last stage of the food path is using nutrients in the body.
