Cells contains structures called?
Chromosomes
How many pairs of chromosomes are present in the human body
23 chromosomes
The testes are inside a protective sack of skin that is called
Scrotum
What is the temperature of the scrotum
1 to 3° lower than the internal body temperature 37° c
There are many tiny cold tube they’re called
Seminiferous tubules
What gland that are responsible for the two hormones secreted by the anterior
Pituitary gland
It stimulates the secretion of the sex hormones testosterone
Luteinizing hormone (LH)
Along with testosterone it stimulates sperm production in the seminiferous tubules
Follicle stimulating hormone
They are produced by leydig cells found between the seminiferous tubules
Testosterone
They are also responsible for developing secondary male characteristics during puberty
Testosterone
They are entering a long coiled tube called ______it is where the mature until they can swim and move and it is where the most of the sperm cells are stored
Epididymis
The mature sperm cells travel from the epididymis to another long coiled tube called __________
Vas deferens
The sperm cells then exits the body through the ____________, a larger tube in males is the same tube through which urine passes and exits the body
Urethra
The mature sperm cells consist of three parts
The head a mid piece and the tail
It contains the chromosomes in mature sperm cells
The head of the sperm
It contains the mitochondria
The midpiece
And that is responsible for the sperms movement
The long tail
The head of the sperm cell is made up of what?
Nucleus
The nucleus is covered by the cap called? And it also stores the enzyme needed to penetrate the egg cell during fertilization
Acrosome
It has alkaline fluid that neutralizes the acids present in the female repro
Prostate gland
A fluid that is rich in sugar does sperm cell uses for energy
Seminal vesicles
Alkaline fluid that neutralizes acidic urine in urethra
Bulbourethral glands
In female reproductive system ______________ triggers the development of secondary female characteristics
Estrogen
The __________ are the female reproductive structures and responsible for producing eggs
Ovaries
