|---|---|---|---|---|---|
| Reproduction | The formation of new individuals
🗑
|
||||
| The reproductive system in humans produces, stores, and releases: | Sex cells/gametes
🗑
|
||||
| Primary reproductive organs | Testes and ovaries (they don't develop until the seventh week)
🗑
|
||||
| Testes produce: | Testosterone
🗑
|
||||
| Ovaries produce: | Estrogen and Progesterone
🗑
|
||||
| Puberty | A period of rapid growth and sexual maturation where the reproductive system becomes fully functional.
🗑
|
||||
| Puberty begins: | Around 9-15 yrs old, when the hypothalamus sends signals to the the pituitary gland in the brain to increase levels of FSH (follicle-stimulating hormone) and LH (luteinizing hormone.
🗑
|
||||
| Main function of male reproductive system: | To produce and deliver sperm
🗑
|
||||
| Testes | Male gonads, on the outside of the body.
🗑
|
||||
| Scrotum | External sac that holds the testes
🗑
|
||||
| Why are the testes on the outside of the body? | Sperm need to be several degrees cooler than the rest of the body so they can develop correctly.
🗑
|
||||
| Seminiferous tubules | Clusters of hundreds of tiny tubes where sperm are produced inside the testes
🗑
|
||||
| Epididymus | Collects fully mature sperm
🗑
|
||||
| Vas deferens | Tube where the sperm travel to the outside of the body
🗑
|
||||
| Urethra | Vas deferens merges with the urethra (Tube that leads to the outside of the body)
🗑
|
||||
| Glands lining the reproductive tract: | The prostate, seminal vesicles, bulbourethral glands
🗑
|
||||
| Glands lining the reproductive tract produce: | Nutrient rich seminal fluid which nourishes sperm and protects them from the acidity of the female reproductive tract.
🗑
|
||||
| Semen | Sperm+seminal fluid
🗑
|
||||
| Autonomic nervous system | Prepares male organs to deliver sperm (involuntarily)
🗑
|
||||
| Ejaculation | Act of sperm being ejected by contractions of smooth muscles (involuntarily)
🗑
|
||||
| Sperm are: | Haploid cells formed by meiosis
🗑
|
||||
| Acrosome | Tip of sperm filled with enzymes to break down outer layer of egg cell
🗑
|
||||
| Head | The head of the sperm contains a highly condensed nucleus
🗑
|
||||
| Midpiece | Part of sperm packed with mitochondria to provide energy to propel sperm forward
🗑
|
||||
| Tail/Flagellum | Propels sperm forward
🗑
|
||||
| Negative feedback system | As levels of testosterone rise, the production of FSH/LH is decreased. Increased production of sperm also inhibits production of FSH/LH. AND VICE VERSA!
🗑
|
||||
| Testosterone | Hormone responsible for growth of male reproductive system and secondary sex characteristics of males.
🗑
|
||||
| Male secondary sex characteristics: | Growth of male sex organs, sperm production, body/facial hair increase, increase in muscle mass, growth of long bones in arms/legs, deepening of voice, broadening shoulders
🗑
|
||||
| Route sperm takes through male reproductive system | Epididymus -> Vas deferens -> Urethra
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
