The respiratory structure that contracts and relaxes to allow air to flow in and out of the lungs is the: Group of answer choice
ohaa [14]

The respiratory structure that contracts and relaxes to allow air to flow in and out of the lungs is option(c) i.e, the diaphragm.

<h3>What is the diaphragm?</h3>

The diaphragm, a delicate skeletal muscle that separates the chest from the belly, is located at the base of the chest. When you breathe in, it flattens and shrinks. As a result, the lungs experience a vacuum effect that draws air in. The diaphragm relaxes and the air is forced out of the lungs when you exhale.

signs of diaphragm issues:

  • Acid reflux, heartburn, coughing, and difficulty swallowing.
  • alterations to skin tone (skin may turn blue).
  • rapid heartbeat, pressure in the chest, and/or breathing difficulties (especially when lying down).
  • Headaches.
  • Hiccups that persist or recur frequently.

Patients who need surgery for conditions affecting the chest, including diaphragm issues, are treated by a thoracic surgeon.

One role of the pancreas is to help regulate blood glucose levels. Two types of cells in the pancreas, beta and alpha, serve as
solniwko [45]

1. Regulation of glucose blood levels is an example of negative feedback mechanism.

Negative feedback mechanism is a control mechanism involved in homeostasis maintain, in this case maintenance of glucose blood levels in normal range.

Negative feedback mechanism contains sensory system that detects the changes, control system that responds to change and activates mechanisms of effector system that reverse the changes in order to restore conditions to their normal levels.

• Pancreatic cells-sensors

• Insulin-control system

• Body cells- effector cells

2. Blood glucose levels change throughout the day because of the food consumption, but in healthy individuals levels of glucose are successfully regulated via the mechanism of hormones such as insulin and glucagon in a process called glucose blood regulation.

This tight regulation of pancreatic hormones is referred to as glucose homeostasis. Insulin lowers blood sugar and glucagon raises it.

3. If the beta cells are destroyed by an autoimmune disease (immune system attacks its own cells), there would be no insulin release, and consequently, the glucose blood levels would be increased.

Diabetes type I is a metabolic disorder caused by the destruction of insulin-producing pancreatic beta cells.
