Male and Female Reproductive Systems Flashcards
Explain five functions of the Female Reproductive System (5)
To produce eggs, to receive sperm, to provide an environment for fertilisation, to provide nutrition to the fetus and to birth the fetus
Explain four functions of the Male Reproductive System (4)
Produce, maintain & transport sperm and produce and secrete hormones

34.4°C
List five physiological and physical changes during puberty for females (5)
Increased body hair
Developing breasts
Acne
Widening of hips
Increased Oestrogen & Progesterone

Ovary
Body of the uterus
Fimbrae
Endometrium
Myometrium
Perimetrium
Cervix
Vagina
How long does it take for sperm to mature? (1)
70 days
Where is the cervix found? (2)
At the bottom of the uterus and the top of the vagina
The uterus is made up of 3 layers, the endometrium, _______ and the perimetrium. (1)
The Myometrium.
What is the function of the endometrium? (2)
This layer is shed during menstruation and provides a suitable environment for implantation.
What is the function of the myometrium? (2)
It is a smooth layer of muscle that contracts during labour under the influence of oxytocin.
What layer of the uterus does the zygote implant into? (1)
Endometrium
The female reproductive system is perfectly designed because.. (1)
The female reproductive system has a straight, continuous path from the external environment to the uterine cavity.
What is the function of the perimetrium? (1)
This layer is constructed of squamous epithelial cells that secrete a lubricating fluid to reduce friction.
The male reproductive system is perfectly designed because.. (1)
The male reproductive system is designed to deposit healthy sperm at the cervix to ultimately result in a pregnancy.
The uterus is the optimum environment for the development of a fetus because.. (2)
it has a rich blood supply and capacity to accommodate a growing fetus.
What layer of the uterus contracts under the influence of oxytocin?
Myometrium
The average menstrual cycle is ___ days. (1)
28.
In which part of the Uterine tube does fertilisation usually occur? (1)
The Ampulla
What hormones do the ovaries produce? (2)
Oestrogen and progesterone.
Is the cervix classed as a part of the uterus? (1)
Yes.
What part of the female reproductive system dilates during labour? (1)
The Cervix
Where are the testes located? (1)
In the scrotum sac.
What is the function of the fimbriae? (1)
To aid the transportation of the ovum from the ovary into the uterine tube.
What is the function of the external female reproductive structures? (2)
To enable sperm to enter the body and to protect the internal genital organs from infectious organisms
What aids the transportation of the ovum through the uterine tube? (1)
Cillia.
What are the protective functions of the female reproductive system? (2)
The labia majora provides a physical barrier to infection and epithelial cells prevent pathogenic microorganisms from entering the body through a mucous barrier.
List the structures of the Male Reproductive system. (9)
Bladder, Urethra, Penis, Seminal Vesicle, Prostate gland, Vas deferens, Epididymis, Testes, Scrotum.
During sexual intercourse, where is sperm is deposited? (1)
The vagina.
