Basic Terran Anatomy

This is only a very basic outline of Anatomy. We have decided to outline only those systems that we believe are necessary to the beginnings of understanding Emergency Medicine. When we have finished the current processes we have undertaken we will begin to explore the Anatomy that is more advanced. We believe these will include such systems as the Immune Response, Endocrine and complexities of the Nervous System.
Cardiovascular System Heart Arteries Veins Capillaries	Digestive System Oral Cavity Esophagus Stomach Small Intestine Large Intestine
Integumentary System Hair Skin Nails	Muscular System Cardiac Muscles Skeletal Muscles Smooth Muscles
Nervous System Brain Sensory Receptor Spinal Cord Nerves	Respiratory System Nasal Cavity Pharynx Larynx Trachea Bronchus Right Lung Left Lung
Skeletal System Cartilage Joint Bones	Urinary System Kidney Ureter Urinary Bladder Urethra

Cardiovascular System	This system has the job of moving blood throughout the body.
Heart	This is a muscle that contracts (squeezes) and relaxes involuntarily (without thinking). It is what causes blood to move through the blood vessels.
Arteries	This is the largest of the blood vessels and carries blood away from the heart. The heart pumps blood through these vessels.
Veins	These are Smaller blood vessels and take blood from the body back to the heart. These vessels have valves to be sure that the blood only goes in one direction.
Capillaries	These are the smallest blood vessels. They carry blood to and from the body tissues.

Digestive System	This system takes food in and breaks it down into nutrients the body can use. This is a process that continues throughout what is known as the Digestive Tract and is completed as waste is excreted (moved outside of the body) from the body.
Oral Cavity	Commonly known as the mouth. It begins physical and chemical digestion. It breaks down Starches.
Esophagus	The tube that links the Mouth and the Stomach.
Stomach	The Stomach begins to further physical and chemical break down of the food substance. It breaks down proteins. The food substance leaves the stomach in a semi liquid like state called chime.
Small Intestine	The small intestine breaks down the chime into usable nutrients with the help of the liver and pancreas.
Large Intestine	The large intestines main goal is to absorb water. From the unusable food substance. And finally the unused substance leaves the body through the Rectum and anal canal.

Integumentary System	This system contains the largest organ (skin) and probably the most important and first defenses for the human body.
Hair	Extension of skin. Protects body in various ways. It protects the head from getting damaged when it is hit, the eyes from dust particles and sunlight, the body for warmth, and the air ways from dust or other similar debris.
Skin	Acts to protect the body from toxins of the outside world. Produces certain vitamins. Excretes urea to cool the body as activity from muscles or environment heat it up.
Nails	Protect the ends of fingers and toes. Similar to hooves of certain animals.

Muscular System	This system is composed of muscles throughout the body. Many of which are voluntary and some which are involuntary.
Cardiac Muscles	Those which make up the heart.
Skeletal Muscles	Those which allow the body to move (usually voluntarily).
Smooth Muscles	These are muscles that line many systems of the body that do not carry out voluntary motions. Most commonly the digestive tract.

Nervous System	This system serves to control the body both voluntarily and involuntarily. It also is the communication system by which the body is controlled in that fashion.
Brain	Located in the head. Controls voluntary and involuntary functions of the body as well as the abilities to think, feel (emotionally and physically), and take action.
Sensory Receptor	These are eyes, ears, nose, mouth and etc.. More specifically the sections of the previous listed organs that receive sensations.
Spinal Cord	This is the main passageway from the brain to the body (in terms of communication).
Nerves	These transmit messages from the spinal cord to the brain or body. In effect they tell the end point what to do.

Respiratory System	This system takes in air and makes it readily available to the rest of the body via the blood.
Nasal Cavity	The cavity of the nose.
Pharynx	It is a tube that is used for both food and air.
Larynx	Opens to air and closes to food. In this way one doesn't breath in food or swallow air. It is also the production of the voice.
Trachea	Known as the wind pipe. This tube goes from the larynx to split into the left and right Bronchi.
Bronchus	Lead from the Trachea into the lungs. Right Lung Composed of 3 lobes. It is were the exchange of oxygen for carbon dioxide is made through the Alveoli and Capillaries surrounding them.
Right Lung	Composed of 3 lobes. It is were the exchange of oxygen for carbon dioxide is made through the Alveoli and Capillaries surrounding them.
Left Lung	Composed of 2 lobes. It is were the exchange of oxygen for carbon dioxide is made through the Alveoli and Capillaries surrounding them.

Skeletal System	System that allows the body movement and protects important structures. Supports the human frame and stores fats and minerals.
Cartilage	Is connective tissue
Joint	Were two bones meet there is usually movement.
Bones	Dense structure that provides the basis for support and movement. It protects various organs and stores fats and minerals.

Urinary System	System in which the body is rid of liquid wastes while retaining appropriate amount of water.
Kidney	Sorts good things from bad things in the blood. It returns good things with the blood back to the system and bad things to the Ureter.
Ureter	This tube leads from the kidneys to the bladder.
Urinary Bladder	This is were the liquid waste is stored until it is excreted.
Urethra	The tube from the bladder to the outside of the body.
