Answer
151. Glands are organs in the human body that synthesize substances such as hormones and discharge them for use or elimination.152. The two main types of glands are:a) Endocrine glands: These release hormones directly into the bloodstream. b) Exocrine glands: These release their secretions through ducts onto epithelial surfaces, such as skin or the lumen of the gastrointestinal tract.153. Hormones are chemical messengers that are secreted directly into the blood, which carries them to organs and tissues of the body to exert their functions.154. Three examples of hormones are:a) Insulinb) Adrenalinec) Thyroxine155. The thyroid gland plays a role in metabolism.156. The pancreas plays a role in metabolism.
Explanation
## Step 1: Understand the questionsThe questions are about the endocrine system, specifically glands, hormones, and the roles of the thyroid gland and the pancreas.## Step 2: Define glands and hormonesGlands are organs in the human body that synthesize substances such as hormones and discharge them for use or elimination. Hormones are chemical messengers that are secreted directly into the blood, which carries them to organs and tissues of the body to exert their functions.## Step 3: Identify the two main types of glands and their functionsThe two main types of glands in the endocrine system are endocrine glands and exocrine glands. Endocrine glands release hormones directly into the bloodstream. These include the pituitary, thyroid, adrenal glands, and others. Exocrine glands release their secretions through ducts onto epithelial surfaces, such as skin or the lumen of the gastrointestinal tract. These include sweat, salivary, mammary, ceruminous, lacrimal, sebaceous, and mucous glands.## Step 4: Give examples of hormonesExamples of hormones include insulin (regulates blood glucose levels), adrenaline (increases heart rate and blood pressure), and thyroxine (regulates metabolism).## Step 5: Understand the role of the thyroid glandThe thyroid gland produces hormones that regulate the body's metabolic rate as well as heart and digestive function, muscle control, brain development, mood, and bone maintenance. Therefore, it plays a role in metabolism.## Step 6: Understand the role of the pancreasThe pancreas has both an endocrine and an exocrine function. As an endocrine gland, it produces insulin and glucagon, which regulate blood sugar levels. Therefore, it plays a role in metabolism.
