Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How long is the ovum in the fallopian tubes?
A
1 day
B
2 days
C
3 days
D
4 days
Explanation: 

Detailed explanation-1: -The fertilized egg stays in the fallopian tube for about 3 to 4 days. But within 24 hours of being fertilized, it starts dividing fast into many cells. It keeps dividing as it moves slowly through the fallopian tube to the uterus. Its next job is to attach to the lining of uterus.

Detailed explanation-2: -An egg only survives 12 to 24 hours after ovulation. If sperm doesn’t’ fertilize the egg, your body reabsorbs it. Unlike your egg, sperm can survive for several days in your body.

Detailed explanation-3: -Adhesive sites on the cilia, which are located on the surface of the fimbriae, are responsible for egg pickup and movement into the tube. The cilia within the tube, and muscular contractions resulting from the movement of the egg, create a forward motion. Transport through the tube takes about 30 hours.
