Reproductive System (the human life cycle (mitosis and meiosis are…

- - - - zygote reproduces millions of times via mitosis and develops within female to change from embryo to fetus
  - - - primary genitalia: gonads that produce gametes
        
        genitalia for females is ovaries
      - secondary genitalia
        
        other stuctures aids reproductice process
        
        are fallopian tube, uterus, vagina, and external genitalia called vulva
        
        ovaries are paired stuctures, 3 cm long in peritoneal cavity
        
        theres ovaries on either side of uterus
        
        several ligaments suspend or anchor each ovary, mesovarium suspends ovary
      - female anatomy
        
        suspensory ligament attaches ovary to later pelvic wall
        
        ovarian ligaments anchors ovary to uterine wall
        
        blood vessels, ovarian artery, and ovarian branch of uterine artery travel through mesovarium and suspensory ligament, supplying ovary with oxygenated blood
- - - - most reproduce themeselves only asexually
      - this is needed for repair and regeneration of tissues
      - growth is accomplished throigh mitosis
      - cells that make up human body are called eukaryotic cells
      - the nucleus cellular organelles usually several chromosomes in the nucleus
        
        chromosomes carry instuction for the cells all cells have complex after reproduction
        
        important for humans because not only do cells have duplicate 46 of their chromosomes have to make that each cell all chromosomes all right organelles
        
        the proce4ss of sorting chromosomes so that new cells coppies genetic matieral called mitosis
        
        only way euaryotic cell can reproduce asexually
  - - - needed for perpetuation (continuation) of species
        
        involves union of cells from organisms cell another organism same species to form unique new organisms
        
        in animal, females reproduce eggs males reproduce sperm and these special cells are called gametes
        
        gametes produced by meiosis or reduction division daughter cells produced at the end of meiosis have half many chromosomes as original
        
        human 46 chromosomes, 23 from another , 23 from father
        
        daughter cells fuse together with gamete from another organism also half chromosomes forming cells that'll have total number chromosomes needed both cells are added together
- - - - cervix
        
        valve like portion of uterus that protrudes in vagina, cervical and communicates with body
        
        like ovaries, uterus is suspended and anchored by series of ligaments
      - mesometrium
        
        attaches uterus to side of pelvic walls
        
        combination of mesometrium and mesovarium called broad ligament
        
        lateral cervical ligaments attachs to cervix and vagina to lateral pelvic wall
        
        uterus abchored to anterior wall of pelvic cavity by round ligament
