Introduction The early students of anatomy and physiology were most likely concerned with treating illnesses and injuries. Early healers relied on superstitions and magic. Later, herbs were used to treat certain ailments. Eventually, after much controversy the study of medicine with standardized terms in Greek and Latin began.

The history of studying the human body is very old – this drawing was by Andreas Vesalius in 1543.

I. What is it? Anatomy: Physiology: Form and organization. Study this through Physiology: How our muscles work. How the eye can see.

Anatomists rely on It is more common to discover new information about

Pathology: By knowing the structure and function of the healthy body, you will be better prepared to understand what can go wrong to cause disease.

Know the names (correct spelling) and functions of each of the 11 systems. Digestive: Digests and absorbs food into nutrient molecules by chemical and mechanical breakdown; eliminates solid wastes into the environment (feces). Stomach, small and large intestine.

Respiratory: Moves oxygen from the external environment into the internal environment; also removes carbon dioxide. Lungs, trachea.

Circulatory: Transports oxygen, carbon dioxide, nutrients, waste products, immune components, and hormones. Heart, blood vessels.

Skeletal: Provides support and protection, and attachment points for muscles. The skeletal system provides rigid framework for movement. It supports and protects the body and body parts, produces blood cells, and stores minerals. Bones and joints.

Lymphatic: Transports excess fluids to and from circulatory system and transports fat to the heart. Also involved in the functioning of the immune system for defense. Lymph nodes, thymus gland, spleen, tonsils.

Integumentary: The outermost protective layer Integumentary: The outermost protective layer. It prevents water loss from and invasion of foreign microorganisms and viruses into the body. Skin.

Muscular: Allows movement and locomotion Muscular: Allows movement and locomotion. Produces body movements, body heat, maintains posture, and supports the body. Muscles.

Endocrine: Works with the nervous system to control the activity internal organs as well as coordinating long-range response to external stimuli. The endocrine system secretes hormones that regulate body metabolism, growth, and reproduction. Glands: thyroid, adrenal, pituitary.

Reproductive: Responsible for survival and perpetuation of the species Reproductive: Responsible for survival and perpetuation of the species. Elements of the reproductive system produce hormones (from endocrine control) that control and aid in sexual development. Organs of this system produce gametes which unite (ova and sperm) to produce new offspring.

Urinary: Regulates volume of internal body fluids as well as eliminates metabolic wastes from the internal environment. The excretory system removes organic wastes from the blood, accumulating wastes as urea in the kidneys. These wastes are then removed as urine. this system is also responsible for maintaining fluid levels. Kidneys, urinary bladder.

Nervous: Coordinates and controls actions of internal organs and body systems. Memory, learning, and conscious thought are a few aspects of the functions of the nervous system. Maintaining autonomic functions such as heartbeat, breathing, control of involuntary muscle actions are performed by some of the parts of this system.
