Topic: Reproduction Aim: Describe the structures that make up the female reproductive system. Do Now: Sit next to your 3 o’clock partner. You will have 4 minutes to discuss and answer questions on the next slide. HW: Fertilization reading notes due tomorrow. Embryonic Development reading Notes due Friday CL Mitosis and Asexual repro due Tuesday, February 24 th.
A BCD E F 1.Identify the process in the diagram above. 2.Identify each phase above. Support your answer.
1.Identify the process above. Support your answer. 2.Where does this process occur? 3.Compare the number of chromosomes in the daughter cells to the original cells.
1. Describe the function of the ovaries. Produce estrogen, progesterone and eggs
Oogenesis
2. Identify the process that releases an egg from as ovary. Ovulation Describe what occurred to the egg that was produced in the ovary.
Identify the four hormones involved in the menstrual cycle.
Why do females take the birth control pill?
3. Once an egg is released from an ovary, into which structure does the egg enter? Oviduct (fallopian tube)
4. Identify the process that can occur in the oviduct if sperm is present? Fertilization Describe fertilization.
5. How does an egg travel towards the uterus? Cilia sweep egg through the oviduct towards the uterus
6. Describe the structure and function of the uterus. Hollow, pear shaped muscular organ Where fertilized egg develops
If egg is fertilized, estrogen and progesterone help make the lining of the uterus thicker. Why?
What happens if the egg is not fertilized? Progesterone is no longer produce and uterine lining and unfertilized egg is shed from the body. (Menstruation)
7. Identify the lower end of the uterus. Cervix
8. Why is the vagina also called the birth canal? During birth, baby travels from uterus to the outside of the body
Ovary Oviduct Uterus Urinary bladder Vagina
Oviduct Ovary Uterus Cervix Vagina
Let’s Review… 1.Explain the process that occurs in the ovaries. 2.Identify AND describe the process that can occur in the oviduct. 3.Explain what occurs if the egg is fertilized. 4.Identify the hormones that cause the thickening of the uterine lining 5.Identify the birth canal. 6.Explain what occurs if the egg is not fertilized.
Ovary Oviduct / Fallopian tube Uterus Ovary Cervix Vagina
The process that occurs in the ovaries is known as (1) mitosis (2) meiosis (3) asexual reproduction (4) locomotion
If sperm are present, fertilization will occur in the (1)vagina (2)ovaries (3)oviduct (4)cervix
Development of the fetus occurs in the (1) vagina (2) uterus (3) cervix (4) ovaries
The diagram below represents chromosomes in a zygote. Which diagrams best illustrate the daughter cells that result from normal MITOTIC cell division of this zygote?
1.Identify the types of cells that sperm and egg are. 2.Identify the process that that produces these cells. 3.Where are these cells produced? 4.In humans, how many chromosomes are found in each of these cells?
1.In which structure will an embryo develop? 2.In which structure can an egg be fertilized? 3.Which structure releases produces and releases eggs? 4.What hormones does structure A secrete? Identify the function of these hormones during the menstual cycle.
1.What process is represented in the diagram above? 2.Put the phases in the correct order. 3.What process is occurring at cell D?
