Your two adrenal glands are small, triangular-shaped endocrine glands located on the top of each kidney. Each adrenal gland is approximately 3 inches wide, and a half inch high. Each gland is divided into an outer cortex and an inner medulla. The cortex and medulla of the adrenal gland secrete different hormones.
The Causes of Ozone Depletion. Scientific evidence indicates that stratospheric ozone is being destroyed by a group of manufactured chemicals, containing chlorine and/or bromine. These chemicals are called ozone-depleting substances (ODS).
Ground-level ozone, commonly known as âsmog,â is the major summertime cause of poor air quality in the Bay Area. The Spare the Air Every Day program was created to reduce summertime ozone pollution. Ozone is essentially an unstable molecule made up of three oxygen atoms. It is created in the lower atmosphere by a combination of pollutants called reactive organic compounds and oxides of nitrogen that get âcookedâ by the sunâs ultraviolet rays in a photochemical reaction.
