7.1.1 Endocrine System

• Hormones secreted by the endocrine system regulate various bodily functions, including growth, metabolism, and reproduction
• Match the gland with its hormone and function:

  Pituitary ↔️ Growth Hormone - Promotes growth

  Thyroid ↔️ Thyroxine - Regulates metabolism

  Pancreas ↔️ Insulin - Controls blood sugar

  Adrenal ↔️ Adrenaline - Responds to stress
• Testosterone, secreted by the testes, regulates male development and reproductive functions
• Adrenaline prepares the body for the fight-or-flight response.

  True
• What is the main role of the endocrine system?

  Regulate bodily functions
• Growth hormone is essential for bone and muscle growth during childhood.


  True
• Where is the pituitary gland located?

  Brain
• The ovaries in females are located in the pelvis
• What hormone does the pancreas secrete to lower blood sugar levels?

  Insulin
• The ovaries secrete estrogen and progesterone, which regulate the menstrual cycle and female reproductive functions
• Match the gland with its primary hormone and function:

  Pituitary Gland ↔️ Growth Hormone, TSH | Regulates other glands, growth

  Thyroid Gland ↔️ Thyroxine | Controls metabolism

  Pancreas ↔️ Insulin, Glucagon | Blood glucose regulation
• What is the primary function of the endocrine system?

  Regulates bodily functions
• Testosterone controls male reproductive functions
• Order the major glands of the endocrine system from head to toe:

  1️⃣ Pituitary Gland

  2️⃣ Thyroid Gland

  3️⃣ Pancreas

  4️⃣ Adrenal Glands

  5️⃣ Ovaries (female) or Testes (male)
• The thyroid gland secretes the hormone thyroxine
• Which hormone regulates blood glucose levels?

  Insulin
• Negative feedback in the endocrine system ensures hormone levels remain in balance
• What is the endocrine system?

  Network of glands
• The endocrine system consists of glands that secrete hormones into the bloodstream.


  True
• Which hormone is secreted by the ovaries in females?

  Estrogen
• Order the key functions of the endocrine system and the hormones involved:

  1️⃣ Growth and Development - Growth Hormone

  2️⃣ Metabolism - Thyroxine

  3️⃣ Reproduction - Estrogen, Testosterone

  4️⃣ Response to Stress - Adrenaline
• Match the function with the corresponding hormone:

  Bone and muscle growth ↔️ Growth Hormone

  Energy use control ↔️ Thyroxine

  Stress response ↔️ Adrenaline

  Menstrual cycle regulation ↔️ Estrogen
• The endocrine system regulates various bodily functions, including growth, metabolism, and reproduction
• Growth hormone promotes bone and muscle growth, which is essential during childhood and adolescence
• Match the gland with its location:

  Pituitary ↔️ Brain

  Thyroid ↔️ Neck

  Pancreas ↔️ Abdomen

  Adrenal ↔️ Above the kidneys

  Ovaries ↔️ Pelvis

  Testes ↔️ Scrotum
• Which gland secretes thyroxine to control metabolism?

  Thyroid
• Match the gland with its key function:

  Pituitary ↔️ Regulates other endocrine glands

  Thyroid ↔️ Controls metabolism

  Pancreas ↔️ Regulates blood sugar

  Adrenal ↔️ Responds to stress
• Which hormone do the testes secrete?

  Testosterone
• The pituitary gland secretes hormones that regulate other endocrine glands
• Adrenaline is secreted by the adrenal glands in response to stress.


  True
• Thyroxine controls the rate at which the body uses energy.


  True
• Which hormone prepares the body for emergencies by triggering the fight-or-flight response?

  Adrenaline
• The thyroid gland is located in the neck.


  True
• Match the characteristic with either hormones or neurotransmitters:

  Transport Medium ↔️ Bloodstream ||| Synaptic clefts

  Response Speed ↔️ Slower ||| Faster
• Positive feedback in the endocrine system prevents overproduction of hormones.

  False
• Order the steps of negative feedback in blood sugar control:

  1️⃣ High blood sugar is detected

  2️⃣ Pancreas secretes insulin

  3️⃣ Insulin lowers blood glucose

  4️⃣ Reduced insulin secretion
