2What are the parts of the Female Reproductive System? Females: All reproductive organs arelocated on the inside of the body-The main job of the reproductive system is to produce offspring.
3Female Reproductive Organs Ovaries: The 2 main organs that are shaped like eggs and located oneach side of the female’s body.
4Female Reproductive Organs -Ovaries produce eggs for reproductionsand the hormones of progesterone(helps prepare for pregnancy) andestrogen (helps regulate the menstrual cycle).
5The Pathways of Eggs The oviduct or fallopian tube is a tube located near each ovary. Each month, eggs are released by the ovaries and travel through the oviduct to the uterus.
6The Pathways of Eggs-The uterus is a hollow organ with thick, muscular walls. If the egg is fertilized by a sperm, the embryo will develop in the uterus.
7The Pathways of Eggs-The narrow bottom of the uterus is called the cervix. The cervix connects the vagina (birth canal) to the uterus.
8The Pathways of Eggs-When a baby is developed, it will leave the uterus, pass through the birth canal and be born.-Female genitalia have 2 external openings. 1 is the urethra (carries urine) and the 2nd one is the vagina used for reproduction.
9Menstrual Cycle -When a female is born, her ovaries contain all the eggs (ovum) she will every have (400,000).-Between puberty and menopause only 450 eggs will mature.-Puberty usually begins between the ages of This marks the beginning of the monthly menstrual cycle or period.
11Ovulation -The menstrual cycle occurs every 28 to 32 days. -It starts due to the release of hormones. One hormone causes an egg to mature, another hormone thickens the walls of the uterus and increases the blood supply, and another hormone causes ovulation which is the release of a mature egg from an ovary.
12Ovulation-If an egg is not fertilized by a sperm while traveling in the oviduct, the hormones will decrease. This causes the thickened walls of the uterus to break apart.-About 14 days after ovulation, menstruation will occur. This is the process of the blood and tissue from the uterus breaking apart and leaving the body.
14Ovulation-This process continues each month until an egg is fertilized by a sperm.-Most females have a menstrual cycle until they are in their 50s. Menopause is when stop having a menstrual cycle.
15Male Reproductive System - The testes are the male reproductive system that produces hormones and sperm.- Testes are egg shaped and located on the outside of the male’s body in a pocket of skin called the scrotum.
16Male Reproductive System The testes produce the hormone, testosterone, (causes a deeper voice and hair growth).They also produce sperm which are stored in an epididymis (a coiled tube).Males continue to make sperm the rest of their life.
