UNFPA works with governments to implement comprehensive sexuality education, both in schools and outside of schools through community-based training and outreach. And because these programmes are based on human rights principles, they advance gender equality and the rights and empowerment of young people.

It is a precondition for exercising full bodily autonomy, which requires not only the right to make choices about one’s body but also the information to make these choices in a meaningful way. Yet research shows that the majority of adolescents lack the knowledge required to make those decisions responsibly, leaving them vulnerable to coercion, sexually transmitted infections and unintended pregnancy.Ĭomprehensive sexuality education enables young people to protect and advocate for their health, well-being and dignity by providing them with a necessary toolkit of knowledge, attitudes and skills. Inferior rectal artery - branch of the internal pudendal artery.Every young person will one day have life-changing decisions to make about their sexual and reproductive health.Middle rectal artery - branch of the internal iliac artery.

Superior rectal artery - terminal continuation of the inferior mesenteric artery.

Fig 3 - Sagittal section of the female pelvis, showing the anatomical position of the rectum.

It is continuous with the anal canal which passes through the pelvic floor to end as the anus. The final segment of the rectum, the ampulla, relaxes to accumulate and temporarily store faeces until defecation occurs. There are additionally three lateral flexures (superior, intermediate and inferior), which are formed by transverse folds of the internal rectum wall. This flexure is formed by the tone of the puborectalis muscle, and contributes significantly to faecal continence.

Anorectal flexure - anteroposterior curve with convexity anteriorly.

Sacral flexure - anteroposterior curve with concavity anteriorly (follows the curve of the sacrum and coccyx).

The course of the rectum is marked by two major flexures: It is macroscopically distinct from the colon, with an absence of taenia coli, haustra, and omental appendices. The rectum begins at the level of the S3 (as a continuation of the sigmoid colon). In this article we will discuss the anatomy of the rectum - its structure, anatomical relationships, and clinical relevance. It is continuous proximally with the sigmoid colon, and terminates into the anal canal. The rectum is the most distal segment of the large intestine, and has an important role as a temporary store of faeces. Visceral afferent (sensory) fibres follow the parasympathetic supply. Parasympathetic supply is from S2-4 via the pelvic splanchnic nerves and inferior hypogastric plexuses. Sympathetic nervous supply to the rectum is from the lumbar splanchnic nerves and superior and inferior hypogastric plexuses.

The rectum receives sensory and autonomic innervation. Note: the rectum is also closely anatomically associated with the rectal venous plexus however this structure is more functionally related to the anal canal. Anastomoses between the portal and systemic veins are located in the wall of anal canal, making this a site of portocaval anastomosis.

The superior rectal vein empties into the portal venous system, whilst the middle and inferior rectal veins empty into the systemic venous system. Venous drainage is via the corresponding superior, middle and inferior rectal veins.

Inferior rectal artery – branch of the internal pudendal artery.

Middle rectal artery – branch of the internal iliac artery.

Superior rectal artery – terminal continuation of the inferior mesenteric artery.

The rectum receives arterial supply through three main arteries:
