Endocrine glands in simple terms class 10 science
let's break down the location and functions of endocrine glands in simple terms:
1. Pituitary Gland: It's like the boss of all glands. Located in your brain, it controls many other glands and growth.
2. Thyroid Gland: This is in your neck. Think of it as your body's thermostat. It regulates metabolism and energy.
3. Adrenal Glands: They sit on top of your kidneys. Imagine them as stress managers. They release hormones for stress response.
4. Pancreas: It's in your abdomen. It's like a sugar regulator, producing insulin to control blood sugar.
5. Ovaries (in females) and Testes (in males): These are responsible for reproduction and secondary sex characteristics.
6. Pineal Gland: Deep in your brain, it's like your sleep manager, producing melatonin for sleep-wake cycles.
7. Hypothalamus: Also in the brain, it talks to the pituitary gland and helps control hunger, thirst, and body temperature.
Remember, these glands release hormones that act as messengers in your body, controlling various functions.
Here are the locations and the hormones released by the mentioned glands:
1. Pituitary Gland: Located in the brain.
- Hormones: Growth Hormone (GH), Prolactin, Thyroid-Stimulating Hormone (TSH), Adrenocorticotropic Hormone (ACTH), and more.
2. Thyroid Gland: Located in the neck.
- Hormones: Thyroxine (T4) and Triiodothyronine (T3) that regulate metabolism.
3. Adrenal Glands: Sit on top of the kidneys.
- Hormones: Cortisol (for stress response), Epinephrine (adrenaline), and Aldosterone (regulates salt and water balance).
4. Pancreas: Located in the abdomen.
- Hormones: Insulin (regulates blood sugar by lowering it) and Glucagon (raises blood sugar).
5. Ovaries (in females) and Testes (in males):
- Ovaries produce Estrogen and Progesterone (female sex hormones).
- Testes produce Testosterone (male sex hormone).
6. Pineal Gland: Deep in the brain.
- Hormone: Melatonin (regulates sleep-wake cycles).
7. Hypothalamus: Also in the brain.
- It controls the release of hormones from the pituitary gland and produces hormones like Oxytocin and Antidiuretic Hormone (ADH).
These hormones play crucial roles in regulating various bodily functions, ensuring your body works properly.

Q. A boy runs on seeing a stray dog. His breathing becomes very fast and blood pressure also increases. Name the
hormone found to be high in his blood and the gland which produces it.
Ans. Adrenaline, Adrenal gland.
Q.Name the diseases by which a person is likely to suffer due to the deficiency of (a) Iodine (b) Insulin
Ans. (a) Goitre (b) Diabetes
Q.How does our body maintain blood sugar level?
Ans. If sugar levels in blood rises, cells of pancreas detect and secrete more insulin which leads to fall off sugar level.
Q.Name the hormone responsible for the regulation of
(i) metabolism of carbohydrates, fats and proteins,
(ii) balance of calcium and phosphate,
(iii) blood pressure,
(iv) water and electrolyte balance.
Ans. (i) Thyroxine
(ii) Parathormone
(iii) Adrenaline
(iv) Vasopressin or ADH (Antidiuretic hormone)
Q.Explain with the help of an example how the timing and amount of hormone released are regulated?
Ans. The timing and amount of hormone released are regulated by feedback mechanisms. For e.g. when there is rise
in sugar level in blood, insulin secreted by pancreas. If sugar lavel in blood fall , insulin secretion is reduced.
Q.Name the hormone that is secreted by our body to deal with scary situations. List any two responses shown by our
body when this hormone is secreted into the blood.
Ans. Adrenaline.
Two responses :
(i) It acts on heart due to which heart beasts faster, resulting in supply of more oxygen to our wooden.
(ii) The breathing rate increases because of the contractions of the diaphragm and the rib muscles
(iii)The blood to the digestive system and skin is reduced due to contraction of muscles around small arteries in these
organs.
