Endocrine System

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.

• Secretes adrenaline to manage stress responses.

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.

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 they affect.

• Hormones are stored in the kidneys until needed.

What do endocrine glands secrete?

• Enzymes

• Hormones

• Neurotransmitters

• Antibodies

What is the primary hormone produced by the adrenal glands?

• Adrenaline

• Cortisol

• Aldosterone

• Insulin

Define homeostasis in the context of the endocrine system.

• Homeostasis is the process of maintaining a stable internal environment in the body.

• Homeostasis refers to the body's ability to adapt to external changes.

• Homeostasis is the mechanism by which the body stores energy.

What hormone is primarily responsible for regulating blood sugar levels?

• Glucagon

• Cortisol

• Adrenaline

• Insulin

What structure is responsible for insulin production?

• The liver.

• The pancreas.

• The kidneys.

• The small intestine.

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 production of all hormones.

• Feedback loops only affect hormone levels during puberty.

• Feedback loops have no impact on hormone regulation.

What is the difference between endocrine and exocrine glands?

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

• Exocrine glands secrete hormones directly into the bloodstream, while endocrine glands secrete substances through ducts.

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

• Exocrine glands secrete hormones that regulate metabolism, while endocrine glands secrete enzymes for digestion.
