| Question | Answer |
|---|---|
| identify the structures and describe the physiological events that take place from ovulation to implantations | ovulation is when a female releases an egg from her ovaries. The egg release is guided into the infundibulum tube, which are wave like motions performed by the fimbriae. The egg reaches the ampulla, a curve in the infundibulum tube... |
| continue 2 | it is also the place that is most likely where the egg is fertilized by sperm. The egg only has 23 chromosomes as well as the sperm having 23 chromosomes and when the egg is fertilized, it becomes a zygote which has 46 chromosomes... |
| continue 3 | In 3-4 days, it reaches the uterus, while it makes its way to the uterus, the uterine walls build up in anticipation, creating implantation. Once the zygote enters the uterus, it becomes blastocyte, which sends out chemical signals that makes sure that .. |
| continue 4 | the uterine wall is ready for implantation. If the signal is positive, then the blastocyte is implanted to the wall, if the signal is negative, then the implantation will be delayed from 2-3 days.... |
| continue 5 | Once implanted, the blastocyte will release human chorionic gonadotropin. It prevents from the uterine wall to build up discharge and allows the blastocyte to develop into a baby. |
| how does "the pill" work as a method of birth control? | The most used contraceptive product in the United States is the pill, the pill makes the female body think it's already pregnant. In each pill, it has estrogens and progesterone, which mimics what the female would have in her body if she was pregnant... |

| list the structures in their proper order and describe the physiological events that take place during the journey of a sperm from spermatogenesis to semen being released | It starts with seminiferous tubule, where spermatogenesis tubule takes place forming sperm. Epididymis holds sperm for 20 days and learns to swim. Ductus (vas) deferens is when male sperm from testicles to urethral... |
| continue listing | Urethral is the last structure of the body where the sperm is being released. |

| 70% of the semen's is coming from where | seminal vesicles |
| what is the volume of seminal vesicles | semen's |
| what do seminal vesicles do | increases sperm motility and fertilizing ability |
| increases sperm motility and fertilizing ability | seminal vesicles |
| how many of the prostate gland is semen | 1/3 |
| what do the prostate gland do | they activate the sperm |
| they activate the sperm | prostate gland |
| 1/3 of this is semen | prostate gland |
| lowest in volume of semen's | bulbourethral |
| what is bulbourethral gland | bulbo-urethral gland |
| what does bulbo-urethral gland do | neutralized the urethral acid |
| neutralized the urethral acid | bulbo-urethral gland |
| vasectomy | surgical procedure, a male can have who is going to keep his sperm from leaving his body (testicles) and go to the urethral |
| surgical procedure, a male can have who is going to keep his sperm from leaving his body (testicles) and go to the urethral | vasectomy |
| what are the layers of the uterine walls | perimetrium, myometrium, and endometrium |
| what is the outer most layer | perimetrium |
| what is the layer that generates contractions | myometrium |
| what is the layer where blastocyte implants and continues to grow into a baby | endometrium |
| when the female ovulates and release the egg, how long is it good for | 12-24 hours |
| when a male releases sperm, it's only good for | 48 hours |
