The middle part of the ureter drains into the right paracaval and interaortocaval nodes on the right, and the left paraaortic nodes on the left. [1] In the lower ureter, lymph may drain into the common iliac lymph nodes, or lower down in the pelvis to the common, external, or internal iliac lymph nodes. [2]
Structures opening in the vulval vestibule are the urethra (urinary meatus), vagina, Bartholin's glands, and Skene's glands. [1]The external urethral orifice is placed about 25–30 millimetres (1–1.2 in) [2] behind the clitoris and immediately in front of that of the vagina; it usually assumes the form of a short, sagittal cleft with slightly raised margins.
The urinary meatus [a] (/ m iː ˈ eɪ t ə s /, mee-AY-təs; pl.: meati or meatuses), also known as the external urethral orifice, is the opening of the penis or vulva where urine exits the urethra during urination. It is also where semen exits during male ejaculation, and other fluids during female ejaculation. The meatus has varying degrees ...
The urethra (pl.: urethras or urethrae) is the tube that connects the urinary bladder to the urinary meatus, [1] [2] through which placental mammals urinate and ejaculate. [3] In non-mammalian vertebrates, the urethra also transports semen but is separate from the urinary tract.
The middle lobe of the prostate causes an elevation in the mucous membrane behind the internal urethral orifice called the uvula of urinary bladder. The uvula can enlarge when the prostate becomes enlarged. The bladder is located below the peritoneal cavity near the pelvic floor and behind the pubic symphysis.
Urination is the release of urine from the bladder to the outside of the body. Urine is released through the urethra and exits the penis or vulva through the urinary meatus in placental mammals, [1] [2]: 38, 364 but is released through the cloaca in other vertebrates.
drainage of urine from the kidney by percutaneous (through the skin) nephrostomy; drainage of fluid collections, e.g. an abdominal abscess; pigtail catheter: used to drain air from around the lung (pneumothorax) administration of intravenous fluids, medication or parenteral nutrition with a peripheral venous catheter or central venous catheter
