What are Labia?

Labia are longitudinal fleshy folds of the vulva, so they are a part of the vulva. Functionally, labia encompass the whole sexual organ of females in order to protect internal organs. The two lips of the labia are recognized as the outer lip and inner lip.

The outer lip is known as labia majora, while the inner lip is known as labia minora. Labia majora are relatively large and containsweat and sebaceous glandsin order to secrete lubricating secretions. Hairs appear in labia majora during puberty. Labia majora are covered with the skin. Labia minora are inside the labia majora and they surround the openings to the vagina and urethra. Labia minora are pink in colour and rich in blood vessels. This part of the labia is more sensitive to stimulation. Labia minora is lined with a mucous membrane; hence it is moist. It is a hairless structure.

What is Vulva?

The vulva refers to the whole area of female external genital organs. It encompasses different parts, including the clitoris, labia minora and labia majora, the opening of theurethraand vagina and the surrounding tissue. These external female genital organs help to deliver sexual pleasure. Labia are the outer and inner lips of the vulva. The clitoris is a sensitive structure situated at the top of the vulva, and it is made up of spongy tissue. Opening of the urethra is a small hole located below the clitoris. Right below the urethral opening, the vaginal opening is situated. From this opening, menstrual blood comes out. Babies are also born through this vaginal opening. The perineum is also a part of the vulva, and it ends in the anus.
