Health Information Management: Human Anatomy

Framework of bones that supports and gives form to the body, protects its internal organs, and provides anchorage points for its muscles. It is composed of about 200 bones.

From The Human Body Book
Muscles are the body’s “flesh”. They bulge and ripple just under the skin, and are arranged in criss-crossing layers down to the bones. Their job is to contract and pull the bones to which they are anchored. Rarely working alone, they usually contract in groups, moving bones at accurate angles and by precise distances.

From The Human Body BookThe heart is a powerful organ about the size of a clenched fist. Located just to the left of centre in between the lungs, it operates as two coordinated pumps that send blood around the body.

From The Human Body Book
he brain, in conjunction with the spinal cord, regulates both non-conscious processes and coordinates most voluntary movement. Furthermore, the brain is the site of consciousness, allowing humans to think and learn.

From The Human Body Book
The respiratory system, in close conjunction with the circulatory system, is responsible for supplying all body cells with essential oxygen and removing potentially harmful carbon dioxide from the body.

From The Human Body Book
The digestive system consists of a lonThe digestive system consists of a long passageway, known as the alimentary canal or digestive tract, and associated organs, including the liver, gallbladder, and pancreas.

System of vessels in an animal's body that transports essential substances (blood or other circulatory fluid) to and from the different parts of the body.

In the body, all the organs and tissues involved in the digestion of food.

Body control system composed of a group of glands that maintain a stable internal environment by producing chemical regulatory substances called hormones.

The adaptable system of body defenses centers on specialized white blood cells called lymphocytes. These respond to invasion by varied microorganisms.

Network of vessels carrying lymph, or tissue-cleansing fluid, from the tissues into the veins of the circulatory system. The lymphatic system functions along with the circulatory system in absorbing nutrients from the small intestines.

From The human body book: An illustrated guide to its structure, function and disorders
Muscle tissue creates bodily movements and it also powers internal processes, from the heartbeat and the movement of food through the intestines to the adjustment of artery diameter and focusing the eye.

Network of specialized tissue that controls actions and reactions of the body and its adjustment to the environment.

In animals, the anatomical organs concerned with production of offspring.

From Britannica Concise EncyclopediaOrgan system involved in respiration. In humans, the diaphragm and, to a lesser extent, the muscles between the ribs generate a pumping action, moving air in and out of the lungs through a system of pipes (conducting airways), divided into upper and lower airway systems.

Group of organs of the body concerned with excretion of urine, that is, water and the waste products of metabolism.

Soft tissue filling the spongy interiors of animal bones. Red marrow is the principal organ that forms blood cells in mammals, including humans. As the skeleton matures, fat-storing yellow marrow displaces red marrow in the shafts of the long bones of the limbs.

The supervisory center of the nervous system in all vertebrates.

Muscular organ that rhythmically contracts to force blood around the body of an animal with a circulatory system.

Muscular hoselike portion of the gastrointestinal tract extending from the lower end of the stomach (pylorus) to the anal opening.

Either of a pair of organs at the back of the abdomen whose function is the removal of waste pro-ducts from the blood, and the excretion of such compounds from the body, usually in the form of urine.

Largest glandular organ of the body, weighing about 3 lb (1.36 kg).

In mammals, large cavity of the body, used for gas exchange.

Glandular organ that secretes digestive enzymes and hormones.

Saclike dilation in the gastrointestinal tract between the esophagus and the intestines , forming an organ of digestion.

From Black's Medical Dictionary
