1 Reproductive Systems

2 Endocrine System Within the Male Reproductive System
Teste Produces testosterone Secondary Sex Characteristics Cowper’s Gland Neutralizes the vagina & urethra Seminal Vesicle Provides energy-rich glucose to the sperm Prostate Gland Provides structure & support

3 Endocrine System in the Female Reproductive System
Ovaries Estrogen Secondary Sex Characteristics Prepares uterus for implantation of embryo Progesterone Builds uterine lining

4 Menstruation Controlled by ovaries and pituitary gland
Follice (days 1-13) FSH Stimulates estrogen production Uterine lining thickens Ovulation (day 14) FSH & LH drop drastically Release egg Corpus Luteum (days 15-21) Empty follicle Increased progesterone Thickens uterine lining Menstruation (days 1-7) Corpus luteum shrivels Stop progesterone Uterine lining shed

5 Stop of Menstruation Pregnancy Menopause Temporary  40 weeks
Permanent

6 Fertilization Types of Fertilization
Internal External Gamete Fusion Oviduct Water Animals Land Fish/ Amphibians Egg # Few Thousands Yolk Size Small Large Fertilization- formation of a zygote within fallopian tube Zygote- fusion of monoploid (1 set of genes) egg and monoploid (1 set of genes) sperm Gametes- sex cells

7 Embryo Formation Fertilization Cleavage- Split
Gastrula: Differentiation Blastula- Hollow Sphere

8 Differentiation Ectoderm Endoderm Mesoderm Skin Nervous System
Digestive System Respiratory System Muscle Circulatory System

9 Embryo Development Internal Umbilical Cord Placenta Inside the uterus
Connection between the mother and fetus Placenta Many blood vessels

10 Malfunctions Miscarriage Corpus luteus breaks down
Uterine lining not thick enough for embryo to implant Abort the embryo
