Human Life Cycle

Meiosis-
Meiosis occurs in ovaries
Phase I occurs in fetal ovary
Phase II of meiosis occurs the moment the egg is fertilized

Fertilization-
The sperm enters the egg to form a zygote. The first cell created

Fetal Development-
Uterus continues to grow since the fetus need to be supported, continues till birth

Birth-
Stage 1- Cervix dilation
Stage 2- Child is born
Stage 3- Placenta is delivered
Childhood/Adolescence-
Adulthood-
Aging-
Many factor causing body to age, Diet, environment, heredity
Death-

Reproduction

Mitosis-
Cell division producing 2 daughter cells that contain the same number and kind of chromosomes as the original cell.

Meiosis-
2 divisions, 4 gametes produced

Fertilization-
The sperm enters the egg to form a zygote. The first cell created

Pre-Embryonic-
First week of embryonic development

Embryonic Development-
2nd week of development lasting until second month of development.

Fetal Development-
Uterus continues to grow since the fetus need to be supported, continues till birth

Female reproductive organs
Eggs-
Produced by the ovaries, lives 6-24 hrs unless fertilization occurs.

Male reproductive organs
Sperm-
Produced in testes, and transported by semen secreted by the prostate and seminal gland during ejaculation

Fetal Development and Birth

Fetus development by Month
Month 3-
Organ systems and gender established and functioning
Month 4-
Skeletal structure
Month 5 –
Monitoring of heart rate
Month 6-
Starts looking human
Month 7 – 9-
Fetus continues to grow and gain weight, eye open, prepares for birth
Birth-
Uterine contractions, hormones start labor for delivery
