Posterior lobe. The posterior, or rear, lobe of the pituitary gland secretes antidiuretic hormone (ADH), which regulates the balance of water in the body. ADH also produces oxytocin, which stimulates uterine contractions during the birth of a baby. Adrenal Glands The are glands that help the body recover from stress and respond to emergencies. They each have two parts. The adrenal cortex secretes a hormone that inhibits the amount of sodium excreted in urine and serves to maintain blood volume and pressure. It also secretes hormones that aid the metabolism of fats, proteins, and carbohydrates. These hor- mones play a role in immunity and the body’s response to stress. The adrenal medulla is controlled by the hypothalamus and the autonomic nervous system. It secretes the hormones epine- phrine (also called adrenaline) and norepinephrine. Epinephrine increases heartbeat and respiration, raises blood pressure, and suppresses the digestive process during periods of high emotion. Problems of the Endocrine System actors such as stress, infection, and changes in the balance of F fluid and minerals in the blood can cause hormone levels to vary. Often these situations will correct themselves. More serious problems, including those described here, may require medication. Diabetes mellitus is a disorder in which the pancreas produces too little or no insulin, resulting in high blood glucose levels. Symptoms include fatigue, weight loss, thirst, and frequent urination. adrenal glands gonads 466 Chapter 18 Endocrine and Reproductive Systems diabetes For more information on different types of diabetes and the risk factors for this disease, see Chapter 26, page 691.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
