The ovaries are a pair of almond-shaped organs that secrete female sex hormones — estrogen and progesterone. It is also responsible for producing a mature egg, which may be fertilized by the male sperm if sexual intercourse takes place.The left and the right ovary take turns to release an ...
aAs more hormones were discovered, they were categorized, primarily according to the process by which they operated on the body. Some glands (which make up the endocrine system) secrete hormones directly into the bloodstream. Such glands include the thyroid and the pituitary. The exocrine system ...
The channel through the cervix is lined with cells and glands that secrete mucus. This mucus is thick and impenetrable to sperm until just before ovulation. At ovulation, the mucus becomes clear and elastic (because the level of the hormoneestrogenincreases). As a result, ...
The primary sex glands that produce the sex cells and manufacture hormones are termed: a. Gingiva b. Gonads c. Gametes d. Genitalia What stage is the oocyte at fertilization? What is the structure in the ovary that holds ova (egg cells)? A. Oviduct B. Follicle C. Uterus D. Corona Rad...

Does the organ secrete any hormones? What are some potential consequences if there is damage to the organ? Share What You've Learned Share your model organ and the information you've gathered with your peer group. Please come prepared with a one-page information hand-out based on the inf...
Following ovulation, the follicular cells that remain in the ovary become the corpus luteum. The cells of the corpus luteum secrete steroid hormones (progesterone and estrogen). If fertilization and implantation are not successful, the corpus luteum begins to degenerate within ten days of being ...
Pituitary production of these hormones depends on secretion of gonadotropin-releasing hormone (GnRH) by the hypothalamus. Elevated levels of GnRH initiate puberty. How does this feedback loop prevent testosterone levels from getting too high or too low? While some may joke that the testis controls...
This minute gland is believed to secrete two hormones which influence the activity of the male gonad. One of these is concerned with the stimulation of spermatogenesis and seems to be identical with the hormone that effects follicular growth in the ovary. The identity of the second hormone,...
Secrete (form glands) —“secretory tissue” Endocrine glands(ductless glands) secrete hormones into blood Exocrine glands(ducted glands) secrete fluids onto surface (incl. into tubes) Structure Cellular junctions Cohesion Junctional complexes Desmosomes— “tangled filaments” hold cells together as in ...
