There are several factors, including substances produced by the body, that are involved in hunger and satiety regulation. Complete each sentence with the appropriate term.

The part of the brain that controls hunger, thirst, and satiety is called the HYPOTHALAMUS. In response to feelings of hunger, your stomach secretes a hormone called GHRELIN, which stimulates eating behavior. The small and large intestines release PEPTIDE YY that signals the stomach to reduce ghrelin secretion when eating has commenced. At the same time, the pancreas releases AMYLIN, a hormone that slows gastric emptying and reduces hunger. Fat cells are also active participants in hunger and satiety regulation. Adipose cells secrete LEPTIN, a hormone that reduces hunger and inhibits fat storage in the body.

Ergogenic aids can be useful in some circumstances, some are possibly useful but still under study, and still others are downright dangerous and illegal. Complete each sentence with the appropriate term related to ergogenic aid use in athletic performance.

One ergogenic aid that may be useful in some circumstances is the use of CREATINE at 20 grams per day for 5-6 days and then a maintenance dose of 2 grams per day to improve performance in those who undertake repeated bursts of activity, such as in sprinting or weightlifting. Promotion of mental alertness by athletes can be achieved through the use of CAFFEINE in a dose of about 3-9 milligrams per kilogram of body weight. A possibly useful—but still under study—ergogenic aid used as an important energy source when carbohydrate stores are depleted are branched-chain amino acids such as leucine, isoleucine, and valine. An ergogenic aid that increases muscle mass but may also cause uncontrolled growth of the heart or other organs and is banned by the International Olympic Committee is growth hormone.

Approximately half of all chemical reactions in the body involve the exchange of electrons. Complete each sentence about oxidation and reduction reactions with the appropriate term.

The exchange of electrons between molecules or atoms during a chemical reaction changes the electrical charge of a molecule. The gain of an electron is called REDUCTION and the loss of an electron is termed OXIDATION. Some reactions result in the production of unstable compounds, also known as FREE RADICALS, which have unpaired electrons and are therefore chemically reactive.

Water plays a variety of roles in the human body. Match the scenario with the corresponding role that water is playing.

Water is part of intracellular and extracellular; During pregnancy, the elevated volume of blood causes water to shift out of the bloodstream and into cells, causing edema. Water helps remove waste products; After drinking alcohol, your urine turns dark yellow; this is indication that you may be dehydrated. Water contributes to body temperature regulation; exercising in a hot climate causes your body to overheat and then work to cool the skin by pushing perspiration out through skin pores. Water helps form lubricants and provides protection in various parts of the body; A pregnant women's fetus is protected by amniotic fluid within the uterus.

Complete each sentence about the balance between water and electrolytes with the appropriate term.

When dissolved in water, some compounds separate into positively and negatively charged ions and enable transmission of an electrical current. Such ions in solution are known as ELECTROLYTES. When the concentration of ions on opposite sides of a cell membrane is imbalanced, water moves across the membrane to the compartment of HIGHEST ion concentration. This movement of water along a concentration gradient is called OSMOSIS. If the INTRACELLULAR concentration of ions is greater than the EXTRACELLULAR concentration, water will move into the cell, which may cause the cell to burst. Cells that line the intestine actively absorb the ion SODIUM. Due to the concentration gradient that is created across the intestinal cell membrane, water in the intestinal lumen is PASSIVELY absorbed, thus allowing absorption of most of the water that enters the GI tract.
