Födelsekanalen

Födelsekanalen, often referred to as the birth canal, is the passage a baby travels through during childbirth. It comprises the cervix, vagina, and perineum. The cervix, the lower, narrow part of the uterus, must dilate to a sufficient width, typically ten centimeters, to allow the baby to pass. Following cervical dilation, the baby descends through the vagina, a muscular canal connecting the cervix to the outside of the body. The perineum, the area of skin and muscle between the vaginal opening and the anus, may also stretch or tear during this process. The elasticity and strength of these structures are crucial for a vaginal birth. The process of the baby moving through the birth canal is known as the second stage of labor. The forces of uterine contractions and maternal pushing help to propel the baby through this passageway. The size and position of the baby, as well as the dimensions of the birth canal, can influence the progress and outcome of labor. In some cases, medical interventions may be necessary if the baby cannot navigate the birth canal effectively.
