6. URINARY BLADDER It is located within the pelvis in back of symphsis pubi . FEMALES Vaginal artery supplies the posterio inferior portion of the Bladder. MALES Inferior vesicular artery supplies the posterio inferior portion of Bladder

7. RECTUM It begins superior to level of third sacral vertebrae and extend from sigmoid colon to puborectalis muscle. It consists of coverings of peritoneal and flexures .

8. ANAL CANAL It starts from puborectalis . Ends at anus. There is a transition from simple columnar epithelium of the gut to stratified squamous epithelium of the epidermis. Two sphincters. Intenal involuntary. External voluntary.

9. REPRODUCTIVE ORGANS EMBRIOLOGY Males Testes are primary sex organs. Vas deferens and epididymis are formed. From the mesonephric ducts. Females Ovaries are primary sex organs Uterine tubes and uterus are derived . From paramesonephric ducts.

11. UTERUS Pear shaped muscular organ between bladder and rectum. Uterus consists of: Fundus Body Isthmus cervix

12. UTERINE TUBES Consists of oviducts and there is no direct connection to ovary. Oviducts open into peritoneal cavity and medially into the uterus. It consists of: Isthmus ampulla infundibulum
