Endocrine System Glands and Organs — NEET Biology
📚 Practice ConceptThe endocrine glands and hormone producing diffused tissues/cells located in different parts of our body constitute the endocrine system. Pituitary, pineal, thyroid, adrenal, pancreas, parathyroid, thymus and gonads (testis in males and ovary in females) are the organised endocrine bodies in our body. In addition to these, some other organs, e.g., gastrointestinal tract, liver, kidney, heart also produce hormones. A brief account of the structure and functions of all major endocrine glands and hypothalamus of the human body is given in the following sections.
Which of the following statements about hormone-producing structures are correct? S1. Pituitary, thyroid, adrenal, pancreas, and gonads are examples of organised endocrine glands. S2. The gastrointestinal tract contains diffuse hormone-producing cells, distinct from classical endocrine glands. S3. Organs like the heart and kidney are not typically considered part of the endocrine system despite producing hormones. S4. A composite gland like the pancreas functions solely as an endocrine gland, secreting hormones. S5. The modern definition of hormones expands the scope beyond chemicals produced only by organised endocrine glands.
