I HAVE A SEXUAL REPRODUCTION TEST MON AND I DIDN'T STUDY

Points I took straight from my reproduction handout for bio class

what is pregnancy

The development of a zygote into an embryo to a fetus in preparation of child birth

Define the stage of infancy

A ‘Baby” is the earliest part of childhood and is from child birth to the age of three.

A Humans Childhood will be between which ages?

4 to 8

At what ages will puberty start?

At ages nine to 13

At which growing stage will puberty start?

Adolescence is the stage where physical and hormonal changes occur, leading to sexual maturity, typically starting between ages nine to thirteen.

At what ages will older adolescence take place ?

14 to 18

Define the stage of adulthood

This stage comes after adolescence starting at the age of nineteen and going on until the person dies

3 names are given to the last stage of human reproduction, they are

Old age, elderly, Seniors

At what age does the last stage of human reproduction take place

51

The general name given to sex cells of both genders

gametes

The name of the female sex cell is called an…

Ovum

What is Fertilization?

The process where a male sperm cell and a female ovum combine to form a zygote, initiating the development of a new organism.

Explain how a zygote forms into a baby.

After fertilization, the zygote undergoes several rounds of cell division, to develop into an embryo and eventually a fetus, growing into a baby over a nine-month gestation period.

Explain how Sex cells contribute to the embryo having characteristics from both

Each Gametes will contain half the amount of chromosomes found in a cell body, in both of their nucleus so that when the two sex cells fuse during fertilization the number of chromosomes to be restored.

An Embryo will get nutrients from the mother through a structure called the…

Placenta

This is the process where the Penis enters the female during intercorse

internal fertilization

Name two structures apart of the female reproductive system that gives nutrients to a ‘baby’

Internally: The placenta Externally: Mammary glands

The testes glands produce which hormone into the body ?

testosterone

List four secondary sexual characteristics a male human during adolescence will undergo due to hormonal changes.

Facial hair

Pubic hair

A deep voice

muscles

Which Hormone is produced by the ovaries when I see a tatted black nerd ?

Oestrogen

List 3 secondary sexual characteristics that ruined my life at the ages 9-thirteen

Broad hips

development of breasts

pubic hair

This Hormone A will have the following effects.

Thickening of the uterus lining

Menstruation

ovulation

Thickening of the uterus lining

Menstruation

ovulation Hormone Oestrogen

Explain the function of progesterone

This is secreted to maintain the thickness of the uterus lining after ovulation

This hormone stimulates the growth of mammary glands in the breasts

Identify the difference between Progesterone and Oestrogen

Both Hormones serve similar but different functions.

Oestrogen serves to develop the thickening of the uterus lining while progesterone helps to maintain that thickened uterus after OVULATION.

Progesterone helps stimulate the development of mammary glands within the breasts while Oestrogen controls menstruation.

Which Hormone in the female body is responsible for developing secondary sexual characteristics?

Oestrogen

During the ages of A to B both girls on average will become SEXUALLY mature.

11 to 15

In Males Puberty begins between the ages

12 and 14

This secondary sexual characteristic due to testosterone results in the voice deepening from the

Voice box becoming enlarged

The name given to the sweat glands that become more active during puberty in both males and females.

Sebaceous glands

List three changes that result from puberty in males that do not fall under the main secondary sexual characteristics

Developing fat above the Abdomen

The development and enlargement of the male testes

They undergo “mood swings” and emotional changes

In females on average puberty begins at the ages

11 to 13

In the male reproductive system sperm is produced by this organ

The testes

The Male organ responsible for producing sperm is contained in a sac called a…

Scrotum

How much sperm is produced by a male till death daily ?

Over 100 million

Where is the male sex cell stored after being produced by the the A male organ

The Epididymis

What is the function of the Urethra In the male reproductive system?

To expel urine and sperm from the Epididymis

label the male reproduction system

This temperature is optimal for sperm production

35c degrees C

match the function with the structure part one

Structure: Testes

Function: Produces the male sex cell (Gametes) called sperm for it to be stored by the epididymis

Match the function with the structure, Part two

Structure: Epididymis

Function: Keeps Sperm cells protected inside the testes

Match the function with the structure part 3

Structure: Scrotum

Function one: Suspends the sperm cells outside of the body at a temperature they are able to survive in.

Function Two: contains and protects the testes

Match the function with the structure Part four

Structure: Vas deferens /sperm duct

Function: Transports sperm cells from the epididymis to the urethra

Match the function with the structure part five

Structure: Cowpers gland

Function: Creates seminal fluid rich in nutrients and enzymes that activate the sperm

Match the function with the structure part six

structure: Prostate gland

Function: This creates seminal fluid rich in nutrients and enzymes which activate the sperm cells

Match the function with the structure part seven
