The correct answer is: A. Pancreas.
The pancreas is a gland that is both endocrine and exocrine. The endocrine part of the pancreas produces hormones that are released into the bloodstream, while the exocrine part of the pancreas produces digestive enzymes that are released into the small intestine.
The pituitary gland is a small, pea-sized gland that is located at the base of the brain. It is often called the “master gland” because it produces hormones that control the function of other glands in the body.
The adrenal glands are two small, triangular glands that are located on top of each kidney. They produce hormones that help the body to respond to stress, regulate blood pressure, and control blood sugar levels.
The pineal gland is a small, cone-shaped gland that is located in the brain. It produces a hormone called melatonin, which helps to regulate the body’s sleep-wake cycle.
The pancreas is the only gland that is both endocrine and exocrine.
