SCIENCE(2)

Question 1

The Sites of Sperm Production. This organ system produces sperm cells (male gametes) and delivers them inside the female reproductive system.

Answer 1

Testes

Question 1

The bag of skin that holds and helps to protect the testicles.

Answer 1

Scrotum

Question 1

Beneath the skin are loose connective tissues and a layer of smooth muscle

Answer 1

Dartos

Question 1

A tightly coiled series of threadlike tubules that form a comma shaped structure on the posterior side of the testes.

Answer 1

Epididymis

Question 2

After the sperm cells become matured in the epididymis, they move through another long tube

Answer 2

Vas deferens

Question 2

This organ secretes alkaline fluid that neutralizes the acids in the female reproductive system. Because of this, the sperm cells are protected from such acidic environment.

Answer 2

Prostate gland

Question 2

Fluid rich in (fructose) sugars that sperm cells use for energy.

Answer 2

Seminal vesicles

Question 3

Alkaline fluid/ white slippery fluid that empties directly into the that neutralizes traces acidic urine in the urethra.

Answer 3

Bulbourethral gland
(Cowper’s gland)

Question 4

Is where the urine passes as it is excreted from the body. This part also has a reproductive function. It aids in the ejection of the semen outside the body.

Answer 4

Urethra

Question 5

The male external organ that deposits the semen into the female reproductive system during an intercourse is the penis. This organ gets filled up with blood during sexual arousal. When filled up with blood, its size increases

Answer 5

Penis

Question 6

the female reproductive structure responsible for producing eggs

Answer 6

Ovaries

Question 7

This tube contracts to assist the movement of the ovum.

Answer 7

Fallopian tubes

Question 8

is a hollow, muscular organ. If fertilization occurs, the zygote implants itself on the lining

Answer 8

Uterus

Question 9

connects the uterus to the vagina. It is especially important during delivery. This widens during childbirth and allows the passage of the fetus from the uterus to the vagina.

Answer 9

Cervix

Question 10

where the sperm is deposited during sexual intercourse. If fertilization occurs and a fetus develops, the baby leaves the mother’s body through

Answer 10

Vagina

Question 11

is a term to describe the sequence of events that occur in your body as it prepares for the possibility of pregnancy each month.

Answer 11

menstrual cycle

Question 12

This phase begins on the first day of your period. It’s when the lining of your uterus sheds through your vagina if pregnancy hasn’t occurred. Most people bleed for three to five days, but a period lasting only three days to as many as seven days is usually not a cause for worry.

Answer 12

MENSTRUAL PHASE

Question 13

This stage of the menstrual cycle is all about your body preparing for pregnancy each month. It starts with your estrogen hormone telling the lining of your uterus to thicken and develop to prepare for a fertilized egg. At the same time, another hormone, known as the follicle-stimulating hormone (FSH), stimulates your ovarian follicles to grow. Each follicle contains an egg. Usually, one egg will get totally ready for fertilization each month.

Answer 13

FOLLICULAR PHASE

Question 14

During this phase, a surge in estrogen triggers a spike in a third hormone – the luteinizing hormone, or LH. LH is what makes a follicle rupture and release an egg. If you have a regular 28day menstrual cycle, the ovulation stage of the menstrual cycle will usually occur on Day 14.
However, most women have different menstrual cycle lengths. In general, ovulation happens 11 to 16 days before your upcoming period. Ovulation is what it’s called when one of the ovaries releases a mature egg. The egg travels out of the ovary, into the nearest fallopian tube, and then into your uterus. As the egg moves down the fallopian tube over the course of several days, the lining of the uterus continues to grow thicker and thicker.

Answer 14

OVULATION PHASE

Question 15

The empty follicle turns into a corpus luteum. The cells of the corpus luteum produce estrogen and large amounts of progesterone. Progesterone stimulates your uterine lining to prepare for a fertilized egg. Here’s where two things can happen. If you become pregnant, the egg moves into your uterus and attaches itself to the lining. If you are not pregnant, the lining of the uterus is shed through the vaginal opening. Your period starts and a new menstrual cycle begins.

Answer 15

LUTEAL PHASE

Question 16

biological processes that maintain homeostasis or body balance.

Answer 16

Feedback loops/mechanism

Question 17

intensifies a response/ increases the production of hormone

Answer 17

positive feedback

Question 18

reduces the effect of a stimulus/ decreases the production of hormones.

Answer 18

negative feedback

Question 19

Draw the feedback mechanism

Answer 19

Hypothalamus(GnRH)
pituitary gland (LH/FSH)
ovary
Estrogen Progesterone
Uterus
