Male and Female Reproductive System Flashcards
(24 cards)
Functions of reproductive organs of male and female?
1) Production of gametes (Sperm and Ovum)
2) Storage of gametes
3) Nourishment of gametes
4) Transport of gametes
5) Fertilization of gametes
Fertilization
Fusion of male and female gametes
to form a zygote
Male Genital (Reproductive) Organs
1) Testes {in side of scrotum (sac)}
2) Epididymis
3) Ductus deferens (Vas deferens)
4) Ejaculatory duct
5) Seminal vesicles
6) Prostate gland
7) Bulbourethral gland
8) Penis
Function of Testes
produce mature spermatozoa(sperms) and testosterone
hormone
Epididymis
This is coiled tube with head, body and tail
regions
Function of Epididymis
Stores and protects spermatozoa
Ductus Deferens (Vas Deferens)
It is a thick fibromuscular tube conveys the sperms from epididymis to the ejaculatory duct in the prostate glands
Seminal Vesicles
Active secretory gland two in number
located behind urinary bladder
Functions of Seminal Vesicles
- Contributes ~70 % to 85% seminal fluid
- Secretions contain fructose,
prostaglandins, fibrinogen
Prostate Gland
It is present below the neck of urinary
bladder and ejaculatory ducts open in its
urethra.
Function of Prostate Gland
Secretes slightly alkaline prostate fluid
CONTENTS OF SEMEN
Normal ejaculate Semen is 2-5 ml It has two parts fluid and sperms *Spermatozoa 15 - 100 million per ml *Seminal fluid A distinct ionic and nutritive glandular secretion mainly
Effects of FSH on Male Reproductive Organs
Targets sustentacular cells to promote
spermatogenesis
Effects of LH on Male Reproductive Organs
Causes secretion of testosterone and other
androgens
Testosterone
Most important androgen
Internal Organs of the female Genital
(reproductive) system
1) Ovaries
2) Uterine tubes
3) Uterus
4) Vagina
Ovaries
* Two in number located on the lateral side of fallopian tubes * Almond in shape *Every month in menstrual cycle the ovulation(release of ovum) and oogenesis formation of ovum take place
Function of Ovaries
Secrets estrogen and progesterone hormones
OOGENESIS & OVULATION
Formation and Release of Ovum occurs every month in ovaries
Uterus
Muscular organ gives the Mechanical protection and Nutritional support for the developing embryo
Structure of Uterus
It is has three parts Fundus , Body and Cervix
Every part has the three layers:
* Endometrium : a thin, inner, glandular layer
* Myometrium : middle muscular layer
* Perimetrium : outer most thin layer .
Uterine tube
- Length: 4 inches
- Has two ends
- Formed of four parts:-
- Infundibulum-Ampulla-Isthmus-Intramural
EXTERNAL GENITALIA of Female
VULVA
1) Labia Minora
2) Labia Majora
3) Vestibule of vagina: It is an area between
two labia minora contains two main openings (vaginal and urethral)
4) Clitoris
HORMONES OF THE FEMALE REPRODUCTIVE
CYCLE
Key hormones
FSH (follicle Stimulating Hormone) and LH (luteinizing hormone) from pituitary gland Controls the hormones of
ovaries “Estrogens &Progesterone”
