The flaggellum (tail) forms so it can swim
It moves into the urethra
It mixes with fluids from the seminal vesicle and prostate gland
What is the vas deferens?
A duct that starts at the epididymis and merges into the urethra.
A duct lined with smooth muscles that contract to move sperm out of the body.
A duct that brings urine and sperm out of the body.

The function of the testes is to ______________________________.
Produce sperm
Prouce testosterone
Produce semen
Why are the testes in the scrotum outside of the body?
The temperature of the scrotum is cooler than inside the body.
The temperature of the scrotum is warmer than inside the body.
Cooler termperatures are needed for healthy and normal sperm to develop.
Warmer termperatures are needed for healthy and normal sperm to develop.
When do males begin to produce sperm?
When they hit puberty
When they are born
When they are adults
What is the role of the hormone testosterone?

All of the above
None of the above
What happens when sperm undergoes meiosis?
One sperm cell splits into four new cells
New sperm cells are created with differnt chromosome combinations
Sperm cells mature and the flagellum (tail) is made so it can swim
Sperm cells are produced
Sperm mixes with fluid madeby the seminal vesicles and prostate gland

chromosomes
mitchondria
enzymes
nucleus
semen
How do the enzymes help the sperm cell?
They nurish the cell
They help the sperm penetrate the protective outer layer of the egg cell
They add fluids to the sperm to protect and nurish it
nucleus
semen
What is the purpose of the mitochondria?
To help the sperm swim in the female reproductive system.
To give teh sperm the energy to swim in the female reproductive system.
They add fluids to the sperm to protect and nurish it
It contains the nucleus and the chromosomes
semen
What is semen?
Sperm mixed with fluids made by the seminal vesicles and the prostate gland.
Sperm made in the seminiferous tublules in the testes.
The fluids made by the prostate gland and the seminal vesicle.
What is semen made up of?
10% sperm, 90% fluids
10% fluids, 90% sperm
Why does semen have a high concentratration of fructose?
Fructose is a sugar that gives the sperm the energy it needs to swim.
Fructose is made up of the fluids made by the seminal vesicles and the prostate gland to protect the sperm.
Frucotse is one of the enzymes contained in the head of the sperm to help it penetrate the egg cell.
Why does semen contain alkaline fluids?
To give the sperm the energy it needs to swim.
To protect the sperm from the acidic environment of the female reproductive system.
To protect and nourish the sperm so it can penetrate the egg cell.
How many sperm cells leave the human body during a single ejaculation?
Just a few
A few million
A few billion
300-400 million
300-400 Billion
Why are so many sperm made and ejaculated from the male reproductive system?
Because so few actually survive.
It increases then chances of fertilization.
Because men are over achievers.
Not all semen contains sperm cells.
