Lyme disease is an infection transmitted by the bite of ticks carrying the spiral-shaped bacterium Borrelia burgdorferi. The disease was named for Lyme, Connecticut, the town where it was first diagnosed in 1975 after a puzzling outbreak of arthritis.ate disseminated disease and chronic lyme disease. Weeks, months, or even years after an untreated tick bite, symptoms can appear in several forms, including: 1  Fatigue, forgetfulness, confusion, mood swings, irritability, numbness.
Pleura of the Lungs. Each lung is enclosed within a cavity that is surrounded by the pleura. The pleura (plural = pleurae) is a serous membrane that surrounds the lung. The right and left pleurae, which enclose the right and left lungs, respectively, are separated by the mediastinum.he major function of the lungs is to perform gas exchange, which requires blood from the pulmonary circulation. This blood supply contains deoxygenated blood and travels to the lungs where erythrocytes, also known as red blood cells, pick up oxygen to be transported to tissues throughout the body.
Here is a list of structures to become familiar with: 1  Mouth and Nose- these are the openings where respiratory gases enter and leave the body. 2  Trachea (windpipe)- this passage way connects the mouth and nose to the lungs. 3  Lungs- these are the balloon-like structures that temporarily hold air in the body. Bronchial tube- the trachea breaks up into these smaller tubes to enter the right and left lungs. Bronchioles- within the lungs the bronchi split into these even smaller tubes which attach to the alveoli. Alveoli- these are the small sac-like structures where gas exchange occurs with the blood.
