Example Question #1 : Understanding Reproductive Organs
What is the structure responsible for the storage of sperm in the male reproductive system?
The epididymis is responsible for storing sperm in order for it to mature. Upon ejaculation, it will be propelled into the vas deferens and out of the urethral opening.
Example Question #2 : Understanding Reproductive Organs
Which female organ is responsible for producing eggs?
Eggs, or oocytes, are produced in the ovaries. During ovulation, the egg is released from the ovary into the fallopian tube. If fertilized, the egg transitions into a zygote and is implanted into the uterus for gestation and development.
The spleen is involved in filtering the blood and lymph, and is not involved in reproduction.
Example Question #3 : Understanding Reproductive Organs
What is the structure that carries eggs from the ovary to the uterus?
The ovaries release eggs into the fallopian tubes, which carry the egg to the uterus.
Fimbriae are protrusions from the fallopian tube that receive the egg from the ovary before transferring it to the fallopian tube itself. The uterus houses the endometrium and, if fertilization occurs, the developing embryo. The cervix is the structure that separates the uterus from the vaginal canal.
An ectopic pregnancy occurs when the egg gets implanted into the fallopian tube rather than the uterus. This is painful, and leads to surgical procedures in order to protect the mother.
Example Question #4 : Understanding Reproductive Organs
Which reproductive organ is divided into three regions: fundus, body, and cervix?
The uterus is a muscular organ in the pelvic cavity. It is also called the womb. The uterus is divided into three regions: the upper region (the fundus), the midportion (the body), and the cervix. The ovaries are almond-shaped organs located in the pelvic cavity. The fallopian tubes connects the ovaries and the uterus. A fallopian tube is divided into three sections: the infundibulum, the ampulla, and isthmus. The vagina, or birth canal, is a muscular tube connecting the cervix to the vulva. The epididymis is a twisted tube that is located on and beside a testis.
Example Question #5 : Understanding Reproductive Organs
Which reproductive organ is located around the urethra, anterior to the rectum, and inferior to the bladder?
The prostate gland is located immediately below the bladder and anterior to the rectum, and it surrounds the urethra. The gland secretes a fluid that becomes part of the seminal fluid. The epididymis rests on and beside the posterior surface of a testis. It is the first part of the secretory duct of each testis. The vas deferans is a continuation of the epididymis and transports sperm from each testis to the ejaculatory duct, which empties into the prostatic urethra. The ovaries are part of the female reproductive system and located in the pelvic cavity attached to the uterus. The ovaries produce the female reproductive cell, the ovum, and hormones. The uterus is located in the pelvis between the sacrum and pubic symphysis. The uterus contains and nourishes the embryo and fetus.
Example Question #6 : Understanding Reproductive Organs
At what age does a female's ovary have the most eggs she will ever have in her lifetime?
In adolescence, at the start of puberty
In the reproductive years: ages 20-30
The ovaries contain 1-2 million eggs at birth. This number slowly declines throughout the female's life. The quality of eggs remaining after age 35 is low, whereby years of spontaneous mutation have occurred.
