Hormonal Regulation of Homeostasis starts at 10 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Hormonal Regulation of Homeostasis.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
Describe how insulin and glucagon work together to maintain blood glucose homeostasis.
Describe the consequences of hyposecretion of ADH.
Describe the effect of thyroxine on metabolic rate.
Describe the role of antidiuretic hormone (ADH) in maintaining water balance in the body.
Describe the role of the hypothalamus in hormonal regulation of homeostasis.
Explain how negative feedback regulates hormone levels in the body.
Explain how the body responds hormonally to a decrease in blood pressure.

A patient has high blood calcium levels. Which hormone is likely to be secreted to restore homeostasis? (1) Parathyroid hormone (2) Calcitonin (3) Insulin (4) Aldosterone
Which gland is primarily responsible for regulating blood glucose levels through the secretion of insulin and glucagon? (1) Thyroid gland (2) Pancreas (3) Adrenal gland (4) Pituitary gland
Which hormone is released by the pancreas to decrease blood glucose levels after a meal? (1) Glucagon (2) Insulin (3) Cortisol (4) Thyroxine
Which hormone is released by the thyroid gland and helps lower blood calcium levels? (1) Parathyroid hormone (2) Calcitonin (3) Insulin (4) Cortisol
Fill in the blank: The ________ gland is often called the 'master gland' because it controls other endocrine glands.
Fill in the blank: The ________ gland produces cortisol, which helps the body respond to stress.
Fill in the blank: The ________ gland produces hormones that regulate metabolism, such as thyroxine.
Fill in the blank: The hormone ________ is released by the adrenal medulla during the 'fight or flight' response.
True or False: Calcitonin increases blood calcium levels.
True or False: Insulin is produced by the alpha cells of the pancreas.
True or False: Negative feedback mechanisms are essential for hormonal regulation of homeostasis.
True or False: The hypothalamus is involved in the hormonal regulation of body temperature.
