Match each hormone to its main role in reproduction.
progesterone-helps thicken the uterine lining oxytocin- stimulates the uterine muscles and induces contractions and labor testosterone- plays a primary role in developing male traits estrogen - plays a role in developing female characteristics and is also important in making the uterus more sensitive to labor-inducing hormones

Which of the following describes the role of estrogen in child birth?
Estrogen increases the response of the muscles in the uterus to oxytocin.
- pathways maintain stable internal conditions. Within the human body, there are receptors that detect the body temperature called - . Regulatory processes are initiated if the body temperature deviates from the - . These regulatory processes involve a - feedback loop. As the skin receptors sense that the body has returned to a normal temperature, the regulatory processes cease.
Homeostatic sensors set point negative
Which of the following scenarios illustrates why homeostasis is important?
If someone has kidney disease, they may experience a build-up of protein, salt, and/or urea in the blood. This can cause lethargy and confusion. If a climber on Mount Everest gets too cold, he may experience mental confusion.

Imagine that the United States started a "Do It for America" campaign to increase birth rates, similar to what Denmark did. Imagine that the campaign was successful the first year in increasing birth rates, so the government increased the number of ads being run for the campaign. The campaign plus the new ads would be an example of which?

Place the following steps of fertilization in the order that they usually occur.

What important developments have occurred at or before the beginning of the third trimester that help a premature baby survive with the help of modern technology?
energy storage in the form of fat development of the circulatory system development of the respiratory system
Transgender individuals born with a male reproductive system sometimes use hormone replacement therapy to induce development of female secondary sex characteristics, such as breasts. What is the main hormone in this hormone replacement therapy?
estrogen
Most women of child-bearing age can get pregnant 365 days a year during her most fertile years.

Negative feedback loops in the body result in loss of homeostasis, whereas positive feedback loops maintain homeostasis in the body.

In homeostatic pathways, if the body deviates from the set point, ____________ feedback loops are initiated.
negative
To maintain homeostasis, an animal body initiates - to decrease outputs back to the normal - . In contrast, - increase processes until - are reached.
negative feedback loops set points Positive fee endpoints
Which of the following organ systems are directly involved with the homeostatic process of human thermoregulation?

If a labor slows or stalls, ______________ (or a chemical derivative thereof) may be given to help induce labor.
oxytocin
Some research has suggested that breast stimulation has the potential to induce labor in pregnant women after their due date. It is a less extreme form of labor induction and may afford women more control over the birthing process. Which of the following hormones is most likely released in response to breast stimulation?
oxytocin
Tina Kold Jensen and colleagues study human reproduction, especially in relation to Denmark's current birth rate concerns. Match the causes and effects below related to human reproduction.
