You need to understand the function of the anus in the digestive system. In the digestive system, the anus has a very large function. This section is the last sequence in the digestive system.
Human body parts are always useful. Each existing part is generally interrelated and has its own function in supporting health.

In the body’s digestive system, there is anus which has a fairly large role. Anus is a digestive tract that is in the human body.
Function of the Anus in the Human Digestive System
Anus is one of the channels in the body. In the digestive system, the anus is at the very end.
Actually the anus is a sewer. As the final opening in the digestive tract, the anus approaches the outside of the body.
The length of the anal canal is about 5 cm and is below the rectum. This is where the digestion process ends.
Anus Anatomy
Before that, you need to know what the anus is first. The anus is the opening which is where the digestive tract ends.
The anal organ is located just below the rectus. The location of the anus itself is in the last part of the large intestine. There is an anorectal line that separates the anus and rectum.
When talking about the function of the anus, then of course it cannot be separated from its anatomy. The anus itself is made up of the pelvic floor muscles as well as the two anal sphincters (internal and external).
Pelvic floor muscles create an angle that exists between the rectum and anus so as to prevent stool from escaping when it shouldn’t.
Meanwhile, the anal sphincter muscle has a function to control the discharge of feces from the anus. The internal sphincter is always tight, except when stool starts to enter the rectum.
The function of this muscle is to help prevent involuntary defecation (encopresis), for example when sleeping.
Meanwhile, the function of the anus in the digestive system is also an external sphincter. This is a circular muscle and forms the anal wall to hold it closed.

This muscle is controlled and contracts when the body needs it. There are glands that produce fluid into the anus to keep moisture in it.
Functions of the Anus in the Digestive System
From the previous explanation, you probably already understand what the function of the anus is. When the rectum is full and the body feels the urge to defecate, the anus functions to expel it.
The internal anal sphincter relaxes and forces the stool to pass. When the external anal sphincter is relaxed, stool moves out of the body through the anus.
However, the function of the anus in the digestive system is actually not only that. Inside the anal canal there is also a mucous membrane in the form of a thin layer of moist tissue.
The mucous membranes are made up of glandular cells that can create mucus to help stool move easily.
Difference Between Anus and Rectum
You may often be fooled into thinking the anus and rectum are the same part. However, these two organs actually have different locations and functions.
The rectum is actually in the deeper part, to be precise at the top of the anus. The rectum serves as a link between the large intestine and the anus.
In separating the rectum and anus, there is an anorectal line. The rectum also only functions as a place for faeces to stop.
Meanwhile, the function of the anus in the digestive system is to remove the feces from the body. So, the rectum will digest the stool that comes from the large intestine, then give the signal to expel it through the anus.
Diseases that can attack the anus
Anus is part of the body. If you don’t take good care of it, then the anus can also experience health problems.

Some diseases that can attack the anus are as follows:
- Internal hemorrhoids and external hemorrhoids
- anal cancer
- Herpes anal
- Anal warts
- Fistula years
- Crack years
- Anal abscess
- Itchy anus
- Proctalgia furax
- Constipation.
When the anus has problems, it cannot carry out its functions properly. Therefore, we need to take care of his health.
Several ways to maintain health so that the function of the anus in the digestive system remains normal is to drink enough water, eat high-fiber foods, and foods rich in probiotics. Then eat slowly and exercise regularly. (R10/HR-Online)
