What is the function of the fallopian tubes?
Click to flip
Fallopian tubes transport eggs from the ovaries to the uterus and are the site where most fertilization occurs.
Click to flip
Explain the role of the uterus in reproduction.
Click to flip
The uterus houses and nourishes the developing fetus during pregnancy.
Click to flip
How does the structure of sperm contribute to its function?
Click to flip
Sperm have a streamlined shape with a head for penetrating the egg, a midsection packed with mitochondria for energy, and a tail for mobility.
Click to flip
Describe the changes that occur in the endometrium during the menstrual cycle.
Click to flip
The endometrium thickens in preparation for a potential pregnancy and sheds if fertilization does not occur.
Click to flip
What is the role of the cervix in the female reproductive system?
Click to flip
The cervix connects the uterus to the vagina and allows the passage of sperm into the uterus and menstrual blood out of the uterus.
Click to flip
Which gland in the male reproductive system produces the fluid that nourishes and transports sperm?
Click to flip
The seminal vesicles produce a fluid that nourishes and transports sperm.
Click to flip
What hormonal changes trigger ovulation?
Click to flip
A surge in luteinizing hormone (LH) triggers ovulation.
Click to flip
Define implantation in the reproductive process.
Click to flip
