Ear collapse is a condition which can be caused by the infection of a cartilage piercing. Although this condition is unusual, especially when a piercing is properly cared for, it is extremely serious, and it requires prompt medical attention.
The human body may be conceptually divided into two major fluid compartments: the intracellular compartment and the extracellular compartment. The intracellular compartment is the space within the organism's cells; it is separated from the extracellular compartment by cell membrane.he third extracellular compartment, the transcellular, consists of those spaces in the body where fluid does not normally collect in larger amounts, or where any significant fluid collection is physiologically nonfunctional.
The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic). The system is responsible for the flow of blood, nutrients, oxygen and other gases, and as well as hormones to and from cells. An average adult has 5 to 6 quarts (4.7 to 5.6 liters) of blood, which is made up of plasma, red blood cells, white blood cells and platelets. The heart is a muscular organ with four chambers. Located just behind and slightly left of the breastbone, it pumps blood through the network of arteries and veins called the cardiovas- cular system. The systemic circulation is a major portion of the circulatory system. The network of veins, arteries and blood vessels transports oxygenated blood from the heart, delivers oxygen and nutrients to the body's cells and then returns deoxygenated blood back to the heart.
