Which of the following best summarizes how hormone levels are controlled? Group of answer choices Hormones are controlled by a f

eedback loop; information about a system is sent back to the controller of the system to improve its function. Hormones are controlled by oxygen levels; the internal environment maintains all systems, including endocrine functions.

Answer: Hormones are controlled by a feedback loop; information about a system is sent back to the controller of the system to improve its function.

Explanation:

Hormones are controlled by a process known as the Negative Feedback Mechanism. This means that when hormone levels get to a particular level, a signal is sent back to the controller of the system to stop it from producing further.

For example, when blood sugar levels are high, the Pancreas will release Insulin. As the insulin works and reduces the blood sugar level this will signal the Pancreas to stop producing further.

The three main treatment options for bone fractures are:

Casting.
Open reduction, and internal fixation- this involves a surgery to repair the fracture-frequently, metal rods, screws or plates are used to repair the bone, and remain in place, under the skin, after the surgery. This procedure is recommended for complicated fractures not able to be realigned (reduced) by casting, or in cases in which the long-term use of a cast is undesirable.
Open reduction, and external fixation- this involves a surgery to repair the fracture, and placement of a external fixation device on the limb with the fracture. This device is an external frame which supports the bone and hold it in the correct position while it is healing. This technique is generally applied to complex fractures that cannot be repaired using open reduction, and internal fixation.

Question # 11

Answer:

Spirometry is one of the most common tests used to diagnose  diseases and disorders of the  respiratory system.

Explanation:

Spirometry is a diagnostic method that allows us to determine the respiratory flow and volume that reflect normal lung function, as well as its possible alterations.

Using a spirometer, data on simple respiratory function is obtained, such as total lung capacity, vital capacity, inspiratory and expiratory tidal volume, as well as their equivalents in forced spirometry.

Spirometry is used for the diagnosis of respiratory diseases as well as for the routine evaluation of patients with chronic lung disease.

<em>     With regard to the other options, since spirometry is limited to the study of lung function, it does not apply to the study of lymphatic, cardiovascular or circulatory systems.</em>
