Where am I?Who am I?. . .
This is the birthcanal where about 250 million sperm enter. Around 99% of them die after 30 minutes. This is where the sperm begin their journey through the reproductive system.
Path to the Chamber of Secrets (Fallopian Tubes)
Is this the path to the chamber of secrets? . . . Ron, you go to the right and I will go to the left.
The remaining 60,000 sperm navigate their way through the cervix . This is the gateway or opening to the uterus. The cervix would dialate 4 inches or 20 centimeters during labor. The sperm must enter in single file through cevical canals. Most will get stuck in one of the 10s or thousands of passageways in the cervix.
I will not let you get her and fertilize her. I will do everything in my power to stop you.
I found her!!!! Thank goodness . . . It is too late, we are already on our way to the hospital wing.
About 3,000 sperm remain after the cervix that must find their way to the fallopian tube. The muscular contarctions will propel the sperm to the fallopian tube with the egg. The sperm are attacked by Leukocytoes or white blood cells that are launched by the immune system. The remaining sperm must find the doorway to the fallopian tube.
Is Ginny okay?
Yes, she is sleeping right now. You got to her just in time Harry.
Approximatley 10 to 30 sperm remain. Once they get to the doorway, they are safe from the white blood cells. The sperm is provided with nourishment from the fallopian tubes such as ph levels, ion concentration stabilize) and they will stay alive for hours or even days.
The remaining sperm will attempt to find the egg at the upper end of the fallopian tube. The egg releases a chemical that leads the sperm in the direction to the egg. The egg only lives for 24 hours so the sperm quickly tries to find the egg. Sperm will onyl live for a few hours after the capacitation process. The sperm that makes contact with the outer coat of the egg has a bag of enzymes on its head an will explode. Once the sperm is inside, the 23 individual chromosomes of the sperm pair up with the 23 chromosomes of the egg (meiosis)
The zygote will travel down the fallopin tubes to the uterus and the cells will begin dividing. On day four the bundle of cells will be called blastocyst. Five days later, the embryo breaks out of its protective and implants itself into the wall of the uterus and will begin to grow into a baby.
