Transcript of The Reproductive
Body system information
A collection of internal and external organs
Male reproductive system consists of two major parts, the testis and the penis.
sperm develop in the seminiferous tubules located in the testis
pain in the pelvis or abdomen
Gastrointestinal: bloating, fluid in abdomen
Abdominal: Lumps, fullness, or fluid
Whole body: Loss of appetite
Also common: Weight loss
During puberty the female starts her menstrual cycle
growth of breast(8-13)
growth of pubic hair (8-14)
body growth (9.5-14.5)
first period (10-16.5)
underarm hair (2 years after pubic hair)
acne (same time as underarm hair)
Growth of testicles and scrotal sac (age 10-13)
Growth of pubic hair (age 10-15)
Body Growth (age 10-16)
Growth of penis (age 11-14)
Change in voice (age 11-14)
Facial and underarm hair (about 2 yrs after pubic hair appears
Acne (About same time as underarm hair)
The road to the Reproductive
Kaitlyn Chisarik and Brittany Galvin
This is a rare cancer that begins in the female organs that produce eggs
This disease needs to be medically treated by a doctor or professional
Body System Information
Primary reproductive organs are ovaries which contain the eggs.
Surgery and chemotherapy are generally used in Ovarian cancer
estrogen is a hormone that helps the sexual and reproductive development in women
The main cause of most type I endometrial cancer imbalance between estrogen and progesterone in the body.
Hysterectomy with removal of the fallopian tubes and ovaries
Testosterone nearly affects every cell in the male body.
It improves muscle mass and bone density and will also have a positive impact on the heart, brain and blood vessels.
Estrogen is made from the circulating testosterone in the body by an enzyme called aromatase.
Increased estrogen means increased fat cells within the body.
Meiosis in the male and female
Sex cells from the male (in testes) and the female (in ovaries) combine for information for reproduction
Meiosis 1: Parent cells are haploid
Interphase: Prepare for divison. Nuclear membrane and nucleus present. Centrioles and DNA replicate. Chromatin present.
Prophase 1: Chromosomes form. sister chromatids form. (form a tetrad). Nuclear membrane and nucleolus disappear. Spindle fibers form
Metaphase 1: Tetrad form in center of cell. Spindles are attacked to centromere of each chromatid.
Anaphase 1: Homologous pairs seperate. Spindle fibers pull one member of each pair to opposite sides.
Telophase 1: Spindle is broken down. Chromosomes uncoil. Cytokinesis takes place.
(No more interphase)
Prophase 2: Spindles form. Centrioles are present. Membrane disappears
Metaphase 2: Chromosomes line up in center of cell. Spindles attach to centromere
Anaphase 2: Centromere splits. Become individual.
Telophase 2: Nucleous and nuclear membrane reappear. Chromosmes uncoil. Cytokinesis takes place. Each new cell contains half of the chromosomes of the original.
Exams and tests
transvaginal pelvic ultrasound
Dilation and curettage
Tests may show endometrial hyperplasia is not cancer but may turn into cancer
Reproduction in the Male
The male reproduction system consists of a number of sex organs that form a part of the human reproductive process.
The main male sex organs are the penis, and the testicles which produce semen and sperm
Statistics for Ovarian cancer
The American Cancer Society estimates for Ovarian cancer in the United States for 2015 are:
about 21,290 women will recieve a new diagnosis of the cancer
about 14,180 women will die from the cancer
Ranks 5th in cancer deaths among women
Unusual vaginal bleeding or discharge
Pain when urinating
Pain during sexual intercourse
Pain in the pelvic area
