FAQs on Glands and Hormones Video Lecture - Science Class 8
| 1. What are glands and hormones? |  |
Ans. Glands are organs in the body that produce and release hormones. Hormones are chemical messengers that regulate various bodily functions and processes.
| 2. How do glands and hormones work together? | |
Ans. Glands produce hormones and release them into the bloodstream. Hormones then travel to specific target cells or organs, where they bind to receptors and trigger specific responses. This communication system helps regulate processes like growth, metabolism, reproduction, and stress response.
| 3. What are some examples of glands and their corresponding hormones? | |
Ans. The pituitary gland produces hormones such as growth hormone, prolactin, and thyroid-stimulating hormone. The thyroid gland produces hormones like thyroxine and triiodothyronine, which regulate metabolism. The adrenal glands produce cortisol and adrenaline, involved in stress response. The ovaries produce estrogen and progesterone, while the testes produce testosterone.
| 4. How can imbalances in glands and hormones affect health? | |
Ans. Imbalances in glands and hormones can lead to various health issues. For example, an underactive thyroid gland can cause fatigue, weight gain, and depression, while an overactive thyroid gland can cause weight loss, anxiety, and rapid heartbeat. Hormonal imbalances can also affect reproductive health, mood stability, and growth and development.
| 5. What are some common disorders related to glands and hormones? | |
Ans. Some common disorders related to glands and hormones include diabetes (resulting from insufficient insulin production or insulin resistance), hypothyroidism (underactive thyroid gland), hyperthyroidism (overactive thyroid gland), and adrenal insufficiency (insufficient production of adrenal hormones). Other conditions include polycystic ovary syndrome, growth hormone deficiency, and Cushing's syndrome.
