REPRODUCTIVE SYSTEM
REPRODUCTIVE SYSTEM

Reproductive System
A system of sex organs within an organism which work together for the purpose of sexual reproduction. Many nonliving substances such as fluids, hormones, and pheromones are also important accessories to there productive system.

Sexual reproduction produces new individuals
- Gametes (sperm & egg) formed by testes and ovaries - Fertilization produces one cell (a zygote)with one set of chromosomes from each parent
- Creates genetic variation .
Gonads produce gametes & secrete sex hormones
Reproductive systems
- Gonads, ducts, glands & supporting structures
- Gynecology is study of female reproductive system - Urology is study of urinary & male reproductive system FEMALE
REPRODUCTIVE
SYSTEM

• It produces the female egg cells necessary for reproduction, called the ova or oocytes
• The system is designed to transport the ova to the site of fertilization.
• To enable sperm to enter the body
• To protect the internal genital organs from infectious organisms
• The mammary glands synthesize, secrete, and eject milk for the nourishment of the newborn.

FUNCTION

• The female reproductive structure is divided into twofold:
• External genital organs
• Internal genital organs

EXTERNAL GENITAL ORGANS

The vulva refers to those parts that are outwardly visible
The vulva includes:

Mons pubis

Labia majora

Labia minora

Clitoris

Urethral opening

Vaginal opening

Perineum

MONS PUBIS
• A rounded mound of fatty tissue that covers the pubic bone.
• During puberty, it becomes covered with hair. • contains oil-secreting (sebaceous) glands that release substances that are involved in sexual attraction pheromones.

LABIA MAJORA
• Enclose and protect the other external reproductive organs. • Literally translated as "large lips," the labia majora are relatively large and fleshy, and are comparable to the scrotum in males.
• Contains sweat and oil-secreting glands. After puberty, the labia majora are covered with hair.

    Endocrine System

    FOCUS: The endocrine system is one of the major regulatory systems in the body, along with the nervous system. However, the endocrine system responds more slowly, and has a longer-lasting, more general effect on the body than the nervous system. Endocrine tissues internally produce hormones which are released into the blood, where they are carried to target tissue and produce a response. Some hormones bind to receptors on the surface of the cell membrane, producing permeability changes or production of a substance inside the cell. Other hormones diffuse into the cell and cause new proteins to be produced. The secretion of hormones is controlled by negative-feedback mechanisms. The major endocrine glands are the pituitary, thyroid, parathyroids, adrenal glands, pancreas, testes, ovaries, thymus, and pineal body.…

    The Sexual Response Cycle

    While most of us are certain that we like to have and enjoy sex, nearly all of us probably have not spent much time pondering about what actually goes on physiologically while we are engaged in the act. Masters and Johnson (two groundbreaking sex therapists) devised the term "sexual-response cycle" to mean the sequence of events that occurs to the body when an individual becomes sexually aroused and takes part in sexually stimulating activities (intercourse, masturbation, foreplay, etc.). Knowing how your body reacts during each phase of the cycle can heighten your relationship and help you single out the cause of any sexual dysfunctions.…

    Polycystic Ovary Syndrome

    The primary sex organs for the female is the ovaries which are also know as female gonads. The ovaries are responsible for producing egg cells and sex hormones. With their almond-shape they nestle into the ovarian fossa which is a depression in the dorsal pelvic wall. The ovaries are divided into an outer cortex where germ cells develop and central medulla which is occupied by major arteries and veins. Within the ovaries each egg develops its own fluid-filled bubble like follicle and is released by ovulation. Several connective tissue ligaments hold the ovaries in place. The ovarian ligament and its lateral pole are attached to pelvic wall by the suspensory ligament. The anterior portion of the ovary is anchored by a portioned fold called the mesorarium which extend to a sheet of peritoneum the broad ligament which flanks the uterus and encloses the…

    Female Reproductive System

    In the female reproductive system, the menstrual cycle is a recurring cycle of physiologic changes that occurs in reproductive-age females. Overt menstruation occurs primarily in humans and close evolutionary relatives such as chimpanzees. The females of other species of placental mammal have estrous cycles, in which the endometrium is completely reabsorbed by the animal (covert menstruation) at the end of its reproductive cycle. The menstrual cycle is under the control of the hormone system and is necessary for reproduction. Menstrual cycles are counted from the first day of menstrual flow, because the onset of menstruation corresponds closely with the hormonal cycle. The menstrual cycle may be divided into several phases, and the length of each phase varies from woman to woman and cycle to cycle. The main phases are the follicular phase, ovulation, the luteal phase, and the menstrual phase. During the follicular phase the lining of the uterus thickens, stimulated by gradually increasing amounts of estrogen from the pituitary gland. Follicles in the ovary begin developing under the influence of a complex interplay of hormones, and after several days one or occasionally two follicles become dominant (non-dominant follicles atrophy and die). The dominant follicle releases an ovum or egg in an event called ovulation. An egg that is fertilized by a spermatozoon will become a zygote, taking one to two weeks to travel down the fallopian tubes to the uterus. If the egg is not fertilized within about a day of ovulation, it will die and be absorbed by the woman's body. After ovulation the remains of the dominant follicle in the ovary become a corpus luteum. This body has a primary function of producing large amounts of progesterone. Under the influence of progesterone, the endometrium (uterine lining) changes to prepare for potential implantation of an embryo to establish a pregnancy. If implantation does not occur within approximately two weeks, the corpus…
