The answer is B, Pancreas. The other four options are all endocrine glands, which produce hormones that are released into the bloodstream to regulate various body functions. The pancreas is an exocrine gland, which means that it releases its secretions (digestive enzymes and bicarbonate) through a duct into the small intestine.
The pituitary gland is a small, pea-sized gland located at the base of the brain. It is often called the “master gland” because it produces hormones that control the function of many other glands in the body.
The hypothalamus is a small, bean-shaped structure located at the base of the brain. It is part of the limbic system, which is involved in emotions, behavior, and memory. The hypothalamus controls many body functions, including body temperature, thirst, hunger, and sleep.
The adrenal glands are two small, triangular glands that sit on top of each kidney. They produce hormones that help the body respond to stress, regulate blood pressure, and control blood sugar levels.
The testes are two oval-shaped organs that are located in the scrotum, which is a sac of skin that hangs below the penis. The testes produce sperm and testosterone, a hormone that is responsible for male sexual development and function.
