Reproductive System Hayle Moran P.1
Major Functions of Reproductive System
: involving two parents (male and female)
: functions to produce a large quantity of male gamete
: process by which new individuals (offspring) of a species is produced by parents
: the point where the egg is fertilized by the sperm
: functions in reproduction of female gamete and preparation for support of developing embryo during pregnancy
: fusion of egg and sperm that produces a zygote
Anatomy of Male and Female Reproductive Structures & Their Functions
: contains fructose, vitamin C and other substances that nourish and activate the sperm
: it is also called the Cowper's Gland, it adds fluids to semen during the process of ejaculation
: it carries sperm from the epididymis to the ejaculatory duct
: it connects the urinary bladder to the penis it also serves as a conduit for semen and sperm during intercourse
it secretes fluid that nourishes and protects sperm and the prostate squeezes this fluid into the urethra and it's expelled with sperm as semen.
: comma-shaped tightly coiled tube which functions to mature and store sperm
: small, muscular sac that contains and protects the testicles, blood vessels, and part of the spermatic cord.
: white sticky milky mixture of secretions from many glands. It also provides transport for sperm
tubular organ which distal portion of urethra passes, it also delivers urine to exterior and delivers semen into the female tract.
: male gamete
: primary female sex organ
: primary sex organ
: delivery of female gamete
Uterine (Fallopian) Tube
: it receives the ovulated ooctye and also provides a site for fertilization, it does not exactly connect to the ovary and is supported by the broad ligament
: Receive a fertilized egg. Retain the fertilized egg. Nourishes the fertilized egg.
: Used as a birth canal and it receives the penis during sexual intercourse.
: Skin folds around the vaginal opening.
: Area is enclosed by labia majora which contains the opening to the urethra and greater vestibular gland or bartholin’s gland
: Contains erectile tissue and corresponds to the male penis and can become engorged with blood during sexual stimulation.
Stimulated by sex hormones mostly estrogen to increase in size for females. Estrogen causes development of glands & fat. Functions to produce milk during pregnancy
Hormones of the Reproductive System
Gonadotropin Releasing Hormone:
Released by hypothalamus in brain to stimulate anterior pituitary gland to release LH and FSH
: Released by testes when high levels of testerone are present to stimulate hypothalamus to release gonadotropin inhibiting hormone to STOP production of LH and FSH
Follicle Stimulating Hormone:
Development and maturation of primary follicle into secondary follicle
: Stimulates reproductive organ development and sex drive
: Spike of hormone will trigger ovulation of most mature follicle (only 1)
Gonadotropin Releasing Hormone:
Released by hypothalamus on brain to stimulate anterior pituitary gland to release LH and FSH
: Decrease release of FSH by anterior pituiatry gland
Follicle Stimulating Hormone
: at puberty stimulate sertoli cells for sperm productions and maturation & inhibin
: Primary female sex hormone released by follicle. It stimulated growth of uterus, vaginal and necessary for ovum maturation
: Stimulates seminiferous tubules to secrete testerone
: Suppression of hypothalamus from releasing GnRH which stimulates development and growth of lining of uterine wall to get ready for implantation
Events of the Hormonal Cycle
: Its triggered by sudden spike increase in LH caused by steady increase in estrogen stimulating the pituitary gland
: Day 1-14 and is the beginning of menstruation cycle into ovulation. It causes follicular cells to develop into the primary follicle which only one
Prepare the uterus for implantation of fertilized ovum
: Occurs in ovaries leading to maturation and ovulation
Disorders of the Reproductive System
- any health issue in a man that lowers the chances of his female partner getting pregnant. Due to problems with his sperm production or with sperm delivery.
- cancer in the male organs that make male hormones and sperm (testicles).
- swelling and inflammation of the prostate gland, a walnut-sized gland situated directly below the bladder in men.
Down Syndrome (Trisomy 21)
- zygote has the incorrect number of chromosomes, it may never start growing.
2nd most common cancer among men (1st is skin cancer).
Sexually transmitted disease
- an infection transmitted through sexual contact, caused by bacteria, viruses, or parasites.
begins in the female organs that produce eggs (ovaries).
a malignant tumor of the cervix, the lowermost part of the uterus.
- virus can be transmitted through contact with infected blood, semen, or vaginal fluids.
