7.1.1 Endocrine System

• The endocrine system uses hormones
• Match the endocrine gland with its location:

  Pituitary Gland ↔️ Base of the brain

  Thyroid Gland ↔️ Front of the neck

  Adrenal Glands ↔️ On top of the kidneys

  Pancreas ↔️ Behind the stomach

  Ovaries ↔️ In the pelvis

  Testes ↔️ In the scrotum
• The ovaries produce sex hormones that regulate the menstrual cycle and prepare the body for pregnancy
• Thyroid hormones regulate the body's metabolic rate.
• What is the signaling method used by the nervous system?

  Electrical impulses
• The nervous system has a slower response time compared to the endocrine system.

  False
• The endocrine system consists of glands that produce and secrete hormones
• The pituitary gland produces hormones that regulate growth, metabolism, reproduction, and stress response
• Hormones are produced by specialized endocrine glands and secreted directly into the bloodstream
• Glucagon raises blood glucose levels.


  True
• What is the signaling method used by the nervous system?

  Electrical impulses
• The pituitary gland produces hormones that regulate growth, metabolism, reproduction, and stress
• What hormone is produced by the testes?

  Testosterone
• Which hormone manages the body's stress response?

  Cortisol
• The nervous system has a faster speed of response
• Match the signaling method with the targeted tissue:

  Hormones ↔️ Widespread

  Electrical impulses ↔️ Localized
• What are glands in the endocrine system responsible for?

  Synthesizing hormones
• The thyroid gland controls metabolism and development.


  True
• Hormones travel through the bloodstream to reach their target tissues.


  True
• The nervous system has a faster response time than the endocrine system.


  True
• What is the function of the thyroid gland?

  Controls metabolism
• Steps in hormone production and transport

  1️⃣ Hormones are produced by endocrine glands

  2️⃣ Hormones are secreted into the bloodstream

  3️⃣ Hormones travel through the blood

  4️⃣ Hormones bind to receptors in target tissues

  5️⃣ Hormones trigger a physiological response
• What are the two main systems that coordinate and regulate the body's functions?

  Endocrine and nervous systems
• What are the chemical messengers used by the endocrine system?

  Hormones
• Hormones are substances that transmit signals throughout the body.

  True
• Which gland produces insulin and glucagon to regulate blood sugar levels?

  Pancreas
• Order the following key hormones based on their function:

  1️⃣ Insulin regulates blood sugar

  2️⃣ Growth hormone promotes growth

  3️⃣ Thyroid hormones control metabolism

  4️⃣ Adrenal hormones manage stress

  5️⃣ Sex hormones regulate reproduction
• What is the endocrine system composed of?

  Glands that produce hormones
• Which system targets widespread tissues in the body?

  Endocrine system
• The pancreas produces insulin to lower blood sugar levels.


  True
• Insulin and glucagon work together to maintain blood sugar levels.

  True
• The nervous system uses hormones as signaling molecules.

  False
• The endocrine system uses hormones in the bloodstream as its signaling method
• The nervous system provides rapid, targeted regulation, while the endocrine system exerts widespread, long-term control.


  True
• Match the endocrine gland with its location:

  Pituitary gland ↔️ Base of the brain

  Thyroid gland ↔️ Front of the neck

  Adrenal glands ↔️ Top of the kidneys

  Pancreas ↔️ Behind the stomach

  Ovaries ↔️ In the pelvis
• Match the endocrine gland with its primary hormone:

  Pituitary gland ↔️ Growth hormone

  Thyroid gland ↔️ Thyroxine

  Adrenal glands ↔️ Cortisol

  Pancreas ↔️ Insulin
• What is the primary function of insulin produced by the pancreas?

  Lowers blood glucose
