Endocrine System

What is the role of the hypothalamus in the endocrine system?

• It regulates blood sugar levels.

• It links the nervous system to the endocrine system and regulates hormone release.

• It produces insulin and glucagon.

• It controls the body's immune response.

What is the role of the parathyroid glands?

• Regulate calcium levels in the blood.

• Produce insulin to regulate blood sugar.

• Control heart rate and blood pressure.

• Aid in digestion by producing enzymes.

How do hormones travel in the body?

• Hormones travel through the lymphatic system to target organs.

• Hormones travel through the bloodstream to target organs.

• Hormones are released directly into the tissues.

• Hormones are stored in the liver until needed.

What is the function of the thyroid gland?

• Regulates metabolism, energy generation, and growth.

• Produces insulin to regulate blood sugar levels.

• Filters toxins from the blood and produces urine.

• Controls the body's response to stress and emergencies.

What do endocrine glands secrete?

• Enzymes

• Hormones

• Neurotransmitters

• Antibodies

What is the difference between endocrine and exocrine glands?

• Endocrine glands secrete hormones directly into the bloodstream, while exocrine glands secrete substances through ducts.

• Endocrine glands are found only in the brain, while exocrine glands are found throughout the body.

• Endocrine glands secrete enzymes, while exocrine glands secrete hormones.

• Endocrine glands have ducts, while exocrine glands do not.

What are the two types of feedback systems that help organisms maintain homeostasis?

• Positive and negative feedback systems.

• Positive and neutral feedback systems.

• Negative and adaptive feedback systems.

• Positive and corrective feedback systems.

What hormone is primarily responsible for regulating blood sugar levels?

• Glucagon

• Cortisol

• Adrenaline

• Insulin

What is the significance of the feedback loop in hormone regulation?

• Feedback loops help maintain balance and prevent overproduction or underproduction of hormones.

• Feedback loops are responsible for the immediate release of hormones into the bloodstream.

• Feedback loops only occur in the presence of external stimuli.

• Feedback loops are irrelevant to hormone regulation.

What is the function of the thymus gland?

• It produces insulin to regulate blood sugar levels.

• It is involved in the development of T-cells for the immune system.

• It filters blood and produces red blood cells.

• It stores bile produced by the liver.
