During childbirth, physical stretching of the uterus causes the release of a hormone that results in stronger, more frequent contractions. These contraction increase the stretching of the uterus. This is an example of

Mammals produce milk to nurse their young. In humans, which hormone controls milk production?

Predict what happens when glucose levels are high in the human body.

In type 1 diabetes, the pancreas doesn't make ______.

There are two types of homeostatic control systems in the body. These include positive and negative feedback systems. Most feedback systems are negative, meaning that the original stimulus is reversed. During a positive feedback loop, the original stimulus is intensified.

What is a good example of a positive feedback loop?

Feedback loops. In a non-living example, we can say that the thermostat in your home is an example of a feedback system.

~Thermostat set at a certain temperature

􏰁~ When the temperature in the room changes the thermostat triggers a heater or air conditioning system

􏰁~ The heater or air conditioning system adjusts to the temperature in the room

􏰁 ~When the thermostat senses that the room has reached the appropriate temperature, the heater or air conditioner turns off.

Imagine this human example. You are at a Zumba class, exercising. Your blood sugar drops. Your pancreas secretes glucagon stimulates the liver to break down glycogen and release glucose back into the blood. Blood sugar increases. Pancreas - glucagon stops.

Compare the human scenario to the thermostat example. What parts of your body are analogous to the parts in of the thermostat example?

The human body is in a continual state of hunger, which is intermittently relieved by eating. The drive to eat is periodically stopped by inhibitory impulses generated by things as the presence of food in the gastrointestinal tract, the flow of nutrients into the blood and other factors. After these satiety factors have dissipated, the desire to eat returns. Scientific studies with lab animals have identified two regions in the hypothalamus that dramatically influence feeding behavior:~lateral hypothalamus - hunger center~ventromedial hypothalamus - satiety centerA rise in blood sugar level after a meal stimulates the pancreas to secrete _____________, which then suppresses appetite by acting on the brain.

I. Stomach stretching

II. Secretion of leptin

III. Increase in blood glucoseIV.

IV. Secretion of pancreas hormones, insulin and amylin

"I cannot eat another bite!" That's what you said after eating the meal you see here. Which of the factors listed above contribute to your feeling of fullness after a meal?

Childhood obesity has tripled over the past 25 years, as obesity in America and many other countries has reached epidemic proportions.

According to the World Health Organization, what statement is true about strategies to reduce obesity?

Margaret is a 62-year-old woman who recently began noticing that she was tired, experienced muscle aches, tenderness and stiffness, dry skin and hoarseness. She was also gaining weight although she had not changed her dietary habits. Because of Margaret's age combined with these symptoms, her doctor suggested that she might have

Lyndon is a 60-year-old smoker. Several years ago Lyndon was diagnosed with COPD, chronic obstructive pulmonary disease and was prescribed prednisone, a synthetic corticosteroid drug. After taking the drug for more than a year, Lyndon has noticed these additional symptoms: high blood pressure, increased abdominal fat accumulation and a growing roundness to his face. His doctor suggested that Lyndon most likely developed cortisol-induced

Some gland dysfunctions can be congenital, meaning the child was born with the abnormality, or can be acquired during or after birth. Growth hormone deficiency, is a condition in which the ______________ gland does not make enough growth hormone. This results in a child's slow growth pattern and an unusually small stature. What gland is responsible for this condition?

Homeostasis in general means regulating and maintaining a stable condition within the body under different conditions. The human skeletal system contributes to three important homeostasis mechanisms. They include all BUT ONE of those listed here.

This gland, found in your brain, is responsible for control of the endocrine system. In addition, it controls many homeostatic functions in your body and helps regulate hunger, thirst, sleep, and wakefulness. What is this gland?

There is a gland in the brain that secretes a multitude of hormones. These hormones stimulate specific glands and tissues in the body: the thyroid gland, ovaries, testes, mammary glands, and the cortex of the adrenal glands. Some call this gland the master gland, but in fact it is stimulated by the hormonal effects of the hypothalamus. What is this gland?

The main function of endocrine glands is to secrete hormones directly into the bloodstream. Hormones are chemical substances that affect the activity of another part of the body, the target site. Hormones serve as messengers, controlling and coordinating activities throughout the body. When an endocrine gland stops functioning properly, you may experience unpleasant or even life-threatening symptoms. Barbara is a 55 year-old woman who is experiencing water retention. Her physician has suggested that the regulation of Barbara's salt and water balance is off, causing the kidneys to retain salt and water and excrete potassium. What malfunctioning gland may be the cause of her condition?

Your endocrine system includes eight major glands throughout your body, such as the thyroid gland, pituitary gland, adrenal gland, and pancreas. This system affects growth and development, metabolism, sexual function, and mood. If your hormone levels are too high or too low, you may have an endocrine disease or disorder.

André the Giant, was a French professional wrestler and actor who famously wrestled with Hulk Hogan in WrestleMania III. What was unique about Andre was his size: 7 feet tall after back surgery. His original wrestling statistics listed him at 7 feet 4 inches, and at his death at age forty-six, he weighed 530 pounds. His size was a result of gigantism, now known to be acromegaly. What is the suspected cause of this condition?

To maintain homeostasis, what will the endocrine system do if the level of glucose in the blood is too high?

Which statement justifies that this gland is a component of the exocrine system?
