In this activity, you will learn about these changes in U.S. demographics and some of the issues facing an aging population. Match the words in the left column to the appropriate blanks in the sentences on the right.
1. *Gerontology* studies the causes of aging and different ways people cope and adjust throughout the process. 2. Over the last century, *life expectancy* in the United States increased dramatically, due to numerous factors, including preventing and controlling of major *infectious diseases* as well as advances in *medical technology*. Other contributing factors include better access to health care and *healthier lifestyles* before the age of 65. 3. The population of people age 65 and older is steadily increasing, and it is likely that this trend will continue due to aging of the *baby boomer* generation. 4. Individuals belonging to the baby boomer generation were born between the *1940s* and the early *1960s*. 5. By *2050* it is expected that people age 60 or older will make up over *20%* of the total population.
Understanding the anatomy and physiology of the heart and the circulatory system is a crucial step in understanding CVD. If you are familiar with how this system operates while healthy, you can then understand better what the consequences are if the delicate balance of the system is disturbed.
1. The cardiovascular system is an intricate organ system that allows blood to flow to and from all parts of the body carrying, among other substances, *oxygen* and nutrients. The system includes the heart and blood vessels: arteries, arterioles, veins, *venules*, and capillaries. The heart is a strong *muscle* about the size of your fist and contains four chambers. The two upper chambers, called *atria*, receive blood that was collected from the body or lungs, whereas the *ventricles*, the two lower chambers, pump the blood from the heart out to the lungs or the body. Most arteries carry *oxygenated* blood from the heart to the rest of the body. The exceptions are the *pulmonary arteries* that carry deoxygenated blood from the heart to the *lungs*, where the blood becomes oxygenated. The four chambers beat in an orchestrated manner due to an *electrical impulse* that when traveling across the heart muscle, gives a signal that causes the orderly contraction of the chambers. This signal starts in the *sinoatrial node (SA node)*, which functions as a natural pacemaker for the heart.
Some believe that the aging process starts at conception; some believe the process begins at birth, and some researchers are convinced that the process starts around age 40.

1. When mineral loss from bones outpaces mineral buildup, bones become more *porous*. 2. Contrary to common belief, *osteoporosis* does not affect only older women, but rather it can occur at any age and affects men as well. Some of the factors that predispose a person to developing this disease are *intrinsic* and some aspects of our life can be modified in order to develop healthy bone density like exercising and eating a diet rich in calcium and vitamin D. 3. Urinary *incontinence* can be the source of embarrassment and isolation; it is not a necessary part of aging, however. The problem can usually be resolved with treatment and exercises that strengthen the pelvic floor. 4. *Presbycusis* is one of the most common chronic conditions of elderly people. Researchers believe that the condition is correlated to mental decline. 5. With age, the ear structure changes in a way that affects the inner ear bones. Since the inner ear contributes to *balance*, exercises like yoga and tai chi can improve quality of life in older adults. 6. As men age, they might experience sexual changes, including *erectile dysfunction*. As women age, they might experience sexual changes that might cause *painful intercourse*. Despite these age-related physiological changes, sex stays an essential component in the lives of elderly people. Recent study reveals that more than 80% of 50- to 90-year-olds are sexually active.

Being aware of the stages of cancer development is a crucial step in understanding cancer. If you are familiar with how cancer develops, you can then understand better the importance of early detection and lifestyle changes that could reduce your risk.
The term "cancer" is used to describe a group of diseases in which *abnormal* cells start dividing *uncontrollably* and invade healthy tissues and organs. These cancerous cells can *metastasize* through the blood or the lymphatic system. When the body is already weakened by disease, stress, or old age, the cancer invasion has more of a chance of succeeding. The rapid and abnormal growth of tissue caused by *cellular proliferation* is called a neoplasm and usually develops into a tumor. Most tumors are not *malignant* , but are *benign*. In the past, the only way to distinguish between the tumors was to perform a *traditional biopsy*. Malignant tumors can invade normal tissues, damage the DNA or RNA, and permanently alter the genetic sequence, creating *mutations*. The *TNM* staging system is used to describe how big a tumor is, the number of lymph nodes affected, and how much it has spread at the time of diagnosis.
