What is the difference between urethra and vagina?

Women's vagina and urethra are both located inside the labia minora, and the two are relatively close, so you should pay attention to hygiene during sex to avoid cross-infection of diseases. Because the urethral opening is not large and is located at the top, it is generally impossible to enter during sex, so don't worry. So, what is the difference between the urethra and the private parts?

The vagina and urethra are different anatomical structures. The vagina belongs to the urinary system, is about 8 to 10 centimeters long, is the sexual organ, and is connected to the female uterus above. The urethral opening belongs to the urogenital system, is about 3 to 5 cm long, is connected to the bladder above, and is the safe passage for urination. The female urethral opening is above the vulva and has a smaller opening. The female vagina and urethra are not in the same cavity, and the interface between the two is inside the vulva. The smaller one at the top is the urethral opening, and the larger one at the bottom is the vaginal opening.

The urethra refers to the safe passage for urination in the human body and is a unique part of the lower urethra. The urethra is not only a safe passage for urination, but also a safe passage for male sperm to be discharged from the body. The male urethra is relatively longer than that of the female, and there are three physiological narrow passages, with a length of 18-20cm. The female urethra is relatively short, only 8-10 cm, and is not physiologically narrow. Private parts mainly refer to the reproductive organs of men and women. Men refer to the penis and scrotum, while women refer to the mons pubis and vulva. Because the reproductive organs are located below the body, Chinese medicine believes that the upper part is yang and the lower part is yin. Because the reproductive organs are also called yin, the area where the reproductive organs are located is called the private parts in human anatomy. The meanings of the urethra and private parts are quite different. They are things of different natures, and their functions are also different. However, according to the anatomical position, the urethral opening is also located at the bottom of the body and is closely related to the reproductive organs, so the private parts include the urethral opening.

Compared with the urethral opening, the vaginal opening is quite large, so as long as you are careful, it is not easy to hurt the urethral opening. And during sexual intercourse, if the couple is not familiar with each other, the woman should have a certain degree of guidance to avoid hurting the urethral opening. Because the urethra, vagina, and anus are close to each other, you must pay attention to hygiene before and after sex to avoid infection.
