Human Reproductive System. Female Reproductive System. The main function of the female reproductive system is to produce ova; eggs cells.
The egg will travel through the fallopian tube until it reaches the uterus.
The uterus is about the size of a pear. It has three layers: an inner layer of epithelial, a middle layer of muscle and an outer layer of connective tissue.
The main function of the male reproductive system is to produce sperm.
The scrotum keeps the testes at a lower temperature then the rest of the body for production of sperm.
During sexual stimulation, the sperm travel to the vas deferens. It is here where semen is produced. Fluids from the prostate gland, the bulbourethral gland secrete fluids that help protect the sperm and allow them to move more easily.
The larger cell will go through meiosis II after it becomes fertilized with a sperm cell. This cell develops into an egg, or ovum cell.
Each developing egg within the ovary is surrounded by a group of cells called a follicle.
After the egg leaves the ovary, it travels through the fallopian tube, where it can be fertilized by a sperm.
If an egg is not fertilized, then pituitary gland stops making FSH and LH. The corpus luteum breaks down, leading to the inhibition of progesterone and estrogen.
For most women the menstrual cycle lasts from pre-teen years until their mid 50s.
allow the sperm to penetrate the egg.
which supplies the sperm with energy.
Once attached, three layers of cells begin to develop: Ectoderm, mesoderm, and endoderm.
Once the structures begin to develop, the ball of cells is now called an embryo.
As the pregnancy continues, membranes will form around the embryo to protect it. The amnion membrane becomes fluid filled and is then called the amniotic sac.
The placenta connects the mother to the fetus. It allows for exchange of nutrients, oxygen, and wastes.
