Organ & System Interactions
Food Digestion
Organ System: A system of organs in the body that work together to carry out a specific purpose
The purpose of the digestive system is to break down food into a usable form for the cells in your body.
There are many organs involved in this process, especially the stomach and small intestine. Food enters the body and flows in one direction, starting in the mouth and exiting the anus. The main purpose of the stomach is to carry out chemical digestion, and partially break down food. The stomach leads directly into the small intestine, which breaks down further and absorbs nutrients of the partially digested food. These two organs work together to break down and absorb nutrients. Neither one could accomplish this task alone. |
Nervous & Muscular system interactions
In order for our body to carry out any actions, it must first receive directions from our brain. When we want to move, our brain sends signals down our neuron cells to our muscle cells.
Generally, when we want to move, our muscle cells receive signals from our brain, causing them to contract.
Our muscles are made up of tons of muscle fibers, each of which are connected to a neuron. We can control how much we contract them because the nervous system regulates our muscles. An action potential received from a neuron triggers the contraction of muscle fibers.
Without this regulation, we wouldn't know how much force we should use to do simple things like stand up or pick up a book.
These two systems must work together in order for the body to function properly. If muscles didn't have anything to tell them what to do, our bodies wouldn't work properly, for example we couldn't move around or our heart couldn't beat.
