Presentation transcript:

THE JOURNEY OF THE SPERM & EGG The student will outline the process of fertilization. The student will illustrate the order of events that take place during fertilization. OBJECTIVES:

Journal- Left Hand Side Write down everything you know about human fertilization. Write in complete sentences, in essay form, using paragraphs.

Key terms- Right Hand Side Ovary Ovulation Zygote Egg Blastocyst Sperm Endometrium DNA Implantation

Egg’s Journey

Egg’s Journey: The OVA is OVULATED out of the OVARY (the egg pops out of the ovary) The sperm meets the egg in the FALLOPIAN TUBE The sperm and egg join and their DNA mixes A fertilized egg is called a ZYGOTE The cells within the zygote will divide and in about a week there will be about 100 cells! A zygote that is about 100 cells big is called a BLASTOCYST Once the blastocyst enters the uterus it is ready to IMPLANT The process of IMPLANTATION is when the blastocyst burrows into the ENDOMETRIUM which is the nutrient rich lining of the uterus.

Sperm’s Journey

Sperm’s Journey https://youtu.be/_5OvgQW6FG4 https://youtu.be/oTLy04hZjHc

A full sentence description of each event GROUP WORK!!!! With a partner, you will: Create a time line of the Fertilization Process You must include: At least 8 events A full sentence description of each event A drawing or illustration of each event An original title for the time line

EXAMPLE OF A TIMELINE: FIRST: Intercourse Millions of sperm cells enter the Vagina LAST: Implantation The blastocyst burrows deep into the Nutrient rich lining of the uterus, where it Will prepare to grow into a human.
