Q

emphysema

A

The progressive, long-term loss of lung function, usually due to smoking. Emphysema is characterized by (1) a decrease in the total number of alveoli, (2) the enlargement of the remaining alveoli, and (3) the progressive destruction of the walls of these remaining alveoli. As the alveoli are destroyed, breathing becomes increasingly rapid, shallow, and difficult. In an effort to compensate for the loss of capacity, the lungs chronically overinflate and the ribcage stays partially expanded all the time, resulting in a slightly rounded shape called a barrel chest.

A

The placement of a solution into the rectum and colon to empty the lower intestine through bowel activity. An enema is sometimes part of the preparation for an endoscopic examination; however, enemas are also used to treat severe constipation and as a means of injecting medication into the body.

39
Q

enteritis

A

An inflammation of the small intestine caused by eating or drinking substances contaminated with viral and bacterial pathogens.

40
Q

Inflammation of the epididymis that is frequently caused by the spread of infection from the urethra or the bladder.

46
Q

epidural anesthesia

A

Regional anesthesia produced by injecting medication into the epidural space of the lumbar or sacral region of the spine. When administered during childbirth, it numbs the nerves from the uterus and birth passage without stopping labor.

47
Q
