rectal

Rectal refers to anything related to the rectum, which is the final section of the large intestine terminating at the anus. The rectum functions as a temporary storage site for stool before it is expelled from the body during defecation. It is approximately 12 centimeters long and plays a key role in maintaining continence by sensing stool presence and coordinating the relaxation of the anal sphincters.

The term "rectal" is commonly used in medical contexts to describe conditions, procedures, or treatments involving the rectum. Common rectal conditions include hemorrhoids, anal fissures, rectal prolapse, and rectal cancer. Symptoms associated with rectal issues can encompass pain, bleeding, itching, and changes in bowel habits.

Rectal examinations are a routine component of physical assessment, often involving digital palpation to detect abnormalities like masses or tenderness. Diagnostic tools such as sigmoidoscopy or colonoscopy allow visualization of the rectal mucosa for further evaluation of suspected pathologies.

Rectal medications are administered directly into the rectum via suppositories, enemas, or creams. These routes provide localized treatment for conditions such as hemorrhoids or inflammation and can also serve for systemic drug delivery in certain cases.

In surgical contexts, procedures involving the rectum may be necessary for cancer removal, fistula repair, or rectal prolapse correction. Due to its vascular and nerve supply, the rectal area is sensitive, and careful consideration is needed in treatment planning.

Overall, the rectum's primary functions relate to waste elimination and maintaining continence, making it a vital component of the digestive system and overall gastrointestinal health.
