The human endocrine system is made up of which of the following structures? (1 point)
vessels
receptors
glands
chambers
2. Which of the following best describes the function of the endocrine system? (1 point)
It secretes chemical messengers that travel through the blood to signal changes at target cells.
It binds chemical messengers that travel through the blood from target cells.
It releases electrical impulses that travel through body cells to signal changes at target cells.
It converts chemical messages into electrical impulses to signal changes at target cells.
3. A hormone is under negative feedback regulation. This hormone stimulates water retention by the body. Which of the following will happen if water levels in the body get too high? (1 point)
Hormone levels will increase.
Hormone levels will decrease.
Antibodies will form.
The kidneys will filter out more urea.
4. Which of the following is true about diabetes? (1 point)
The pancreas overproduces glucose, and so insulin must be injected to reduce glucose levels.
The pancreas underproduces glucose, and so insulin must be injected to increase glucose levels.
The pancreas overproduces insulin, and so glucose must be injected to regulate insulin levels.
The pancreas underproduces insulin, and so insulin must be injected to regulate glucose levels.
5. How do the circulatory system and the endocrine system interact in helping to maintain homeostasis in humans? (1 point)
The endocrine system produces hormones that are transported by the circulatory system to target cells when changes are needed.
The circulatory system provides a way to transport cellular waste products to the endocrine system, which disposes of them.
The endocrine system provides a storage site for excess raw materials needed by cells, and the circulatory system provides a means for transporting them.
The circulatory system signals to target cells in the endocrine system when changes need to be made to maintain balance in the body.
6. Which of the following lists the phases in the correct order with respect to their occurrence in human development?
a – maturation of ovaries and testes
b – loss of muscle tissue
c – development of problem-solving skills
d – learning to walk (1 point)
c, b, d, a
b, a, c, d
d, c, a, b
a, d, b, c

1. The human endocrine system is made up of glands.
To get this answer, one can study the human anatomy and specifically focus on the endocrine system. The endocrine system consists of various glands, such as the pituitary gland, thyroid gland, adrenal glands, pancreas, and many others.
2. The function of the endocrine system is to secrete chemical messengers that travel through the blood to signal changes at target cells.
To answer this question, one can study the role of the endocrine system in the body. The endocrine glands produce hormones, which are chemical messengers that travel through the bloodstream to specific target cells. These hormones regulate various bodily functions and help maintain homeostasis.
3. If water levels in the body get too high, hormone levels will decrease.
To understand this question, it is important to understand the concept of negative feedback regulation. In negative feedback, the response opposes the initial stimulus. In this case, the hormone stimulates water retention by the body. If water levels become too high, the body will reduce hormone levels to prevent further water retention and restore balance.
4. The pancreas underproduces insulin, and so insulin must be injected to regulate glucose levels.
To answer this question, one needs to have knowledge about diabetes and its causes. In type 1 diabetes, the pancreas underproduces insulin, a hormone that regulates glucose levels. As a result, individuals with type 1 diabetes need to inject insulin to control their blood sugar levels.
5. The endocrine system produces hormones that are transported by the circulatory system to target cells when changes are needed.
To understand the interaction between the circulatory system and the endocrine system, one needs to know how hormones travel throughout the body. Hormones produced by the endocrine system are released into the bloodstream and transported by the circulatory system to target cells or organs where changes are needed for homeostasis.
6. The correct order of phases in human development is d, c, a, b.
To answer this question, one needs knowledge about human development stages. The correct order is as follows:
- Learning to walk (d) typically occurs during early childhood.
- Development of problem-solving skills (c) usually happens during childhood and continues into adolescence.
- Maturation of ovaries and testes (a) occurs during puberty, which is the start of sexual maturation.
- Loss of muscle tissue (b) generally happens with aging, as muscle mass tends to decrease over time.
