Sorry if I missed any organ and its functions
For the Female Reproductive Side View, please check your packet because I could not find any blank diagrams to edit and due to laziness.
WHY DO WE HAVE SEX?! : TO INCREASE GENETIC VARIATION AND INCREASE THE CHANCE OF SURVIVAL OF SPECIES!
Two types of reproduction: Asexual and sexual.
-Asexual - One parent, offspring alone. (Bacteria, plants, amoebas, and simple organisms)
-Sexual - Joining of gametes increasing variation
Male Secondary Sex Characteristics: FHS stimulates testes to produce testosterone.
-Testosterone causes larynx wider (deeper voice), broader shoulders, facial hair, pubic hair, and muscle growth.
Female Secondary Sex Characteristics: FHS stimulates ovaries to produce estrogen.
-Estrogen causes wider hips for child delivery, breasts, pubic hair.
Terms:
Pituitary Gland - Secretes hormones and regulates other endocrine glands
Hypothalamus - Integrates the endocrine and nervous system as well as controlling the pituitary gland
Endocrine system regulates by a feedback mechanism: Positive and Negative.
Positive: When hormones are low, hypothalamus signals the pituitary to secrete more hormones
Negative: When hormones are high, production of hormones come to halt
FSH (Follicle-Stimulating Hormone): Stimulates production of mature eggs in ovaries.
LH (Luteinizing hormone): Stimulates ovaries and prepares for implantation of fertilized egg.
Check chapter 34.2 in your textbook which starts on page 982.
Zygote: Fertilized egg
Cleavage: Creates a cleave when cells are dividing
Chorion: Develops into a placenta
Amnion: Develops to amniotic sac which cushions the fetus
Gastrulation: Formation of 3 embryonic germ layer
-Endoderm - lining of digestive, reproductive, and respiratory systems
-Mesoderm - muscles, blood, and bones
-Ectoderm - skin and nervous system
Placenta and umbilical cord connect the fetus to mother
-Provides energy and oxygen and removes waste and carbon dioxide
Amniotic sac cushions the fetus
Contraception is preventing the union of egg and sperm
Forms of contraception:
-Abstinence (Safest way to prevent pregnancy)
-Condom
-Birth Control Pills
-Tubal Ligation (Woman's tube gets tied)
-Vasectomy (Cuts vas deferens where sperm travels)
Hope this helps you ladies and gentlemen study.
Good luck
THE NEXT SCRIBE SHALL BE (DRUM ROLLLLLLLLLLLLLLLLLLLLLLLL)
