rectal culture information from trusted sources:
Rectal culture is a laboratory test to identify organisms in the rectum that can cause gastrointestinal symptoms and disease.
The rectum is the lower part of the colon that connects the large bowel to the anus. The rectum's primary function is to store formed stool in preparation for evacuation. Like the colon, the 3 layers of the rectal wall are as follows: Mucosa: This layer of the rectal wall lines the inner surface. The mucosa is composed of glands that secrete mucus to help the passage of stool. Muscularis propria: This middle layer of the rectal wall is composed of muscles that help the rectum keep its shape and contract in a coordinated fashion to expel stool. Mesorectum: This fatty tissue surrounds the rectum. In addition to these 3 layers, another important component of the rectum is the surrounding lymph nodes (also called regional lymph nodes). Lymph nodes are part of the immune system and assist in conducting surveillance for harmful materials (including viruses and bacteria) that may be threatening the body. Lymph nodes surround every organ in the body, including the rectum.
Hemorrhoids, also called piles, are swollen and inflamed veins in your anus and lower rectum. Hemorrhoids may result from straining during a bowel movement or from the increased pressure on these veins during pregnancy, among other causes.
Hemorrhoids (hem-roids) are swollen veins in the rectum or anus (rear end). They are also called "piles." You may have inside or outside hemorrhoids. Inside hemorrhoids are found where the anal canal starts (rectum). Outside hemorrhoids are found around your anus. The anus is the hole where you have a BM. You may have hemorrhoids for years before you have problems.
A mass of dilated, tortuous veins in the anorectum involving the venous plexuses of that area. There are two kinds: external, those involving veins distal to the anorectal line (a dilated vein or veins at the junction of anal mucosa with the anal skin), and internal, those involving veins proximal to the anorectal line (dilated veins of the lower rectum at the anal-rectal junction). Usually related to constipation, pregnancy, improper diet, lack of exercise, prolonged periods of sitting, heavy lifting, obesity, liver damage, and allergies. Approximately half of the population of the United States over fifty years of age suffer from hemorrhoids.
There are several ways that you can help reduce your risk of developing cancer of the colon, rectum, or bowel.
