munanjohtojen

Munanjohtojen, also known as fallopian tubes or oviducts, are a crucial part of the female reproductive system. These are two thin, muscular tubes that extend from the upper part of the uterus towards the ovaries. Each tube is approximately 10 to 13 centimeters long and about 0.5 to 1 centimeter in diameter. The inner lining of the fallopian tubes is covered with cilia, which are tiny hair-like structures that beat in a coordinated manner. This ciliary action, along with muscular contractions of the tube, helps to transport the egg from the ovary to the uterus.

The fimbriae are finger-like projections located at the ovarian end of the fallopian tube. While they do not directly attach to the ovary, they sweep over the surface of the ovary during ovulation to capture the released egg. Fertilization, the fusion of sperm and egg, typically occurs within the fallopian tube. After fertilization, the resulting zygote begins to divide and is then moved down the tube to the uterus, where it can implant and develop into a fetus. If fertilization does not occur, the egg degenerates and is absorbed or expelled from the body.

Problems with the fallopian tubes, such as blockages or infections, can lead to infertility or ectopic pregnancy, where a fertilized egg implants outside the uterus, most commonly in the fallopian tube itself. These conditions require medical attention. Regular check-ups and prompt treatment of any reproductive health concerns are important for maintaining the health of the munanjohtojen and overall reproductive well-being.
