Intro to Anatomy

Body systems

Describe Anatomy The study of the structure of body parts and their relationships to one another. they can be felt, seen and examined.
Describe Physiology Concerns the functioning of the body's structural machinery and how the parts of the body work.
What is Gross/Macroscopic Anatomy Structures studied with out a microscope
What is Surface Anatomy The study of morphology and markings of the surface of the body
What is Regional anatomy It is concerned with a specific area of the body.
What is Microscopic Anatomy The structures studied with a microscope.
Name in order of increasing complexity the levels of structural organisation. Chemical Level (Atoms & Molecules)Cellular Level (Made up of Molecules)Tissue Level (Consists of simular types of cells)Organ Level (different types of Tissues)Organ System LevelOrganismal Level (Whole Body)
Describe the Integumentary System Skin - keeps the organs from drying out Forms the external cover
Describe the Skeletal System Bones - Protects and Supports the Body Organs
Describe the Muscular System Creates movement by using bones to creat locomotion, maintains posture and produces heat.
Describe the Nervous System Fast acting control system, responds to internal and external changes by activating appropriate muscles and glands.
Describe the Endocrine System Glands Screte hormones that regulate processes like growth and reproduction.
Describe the Cardiovascular System Blood Vessels transport blood that carries oxygen nutrients and waste.
Describe the Lymphatic System Houses white blood cells involved in immunity.
Describe the Respiratory System Lungs - Keeps blood constantly supplied with oxygen and removes carbon dioxide.
Describe the Digestive System Breaks down food into absorable units that enter the blood for distribution to body cells
Describe the Urinary System Eliminates nitrogens wastes from the body, regulates water electroyte and acid base balance from the blood.
Describe the Reproductive System Over function is production of offspring.
Name the body systems Integumentary Skeletal Muscular Nervous Endocrine Cardiovascular Lymphatic Respiratory Digestive Urinary Reproductive
What is Homeostatis the body's ability to maintain a relatively stable state internally when there is continuous change on the outside.
Name the General Control Mechanisms Stimulus - pickes up changes in VariablesReceptors - detect changes sends response via afferent pathway to Control CentreControl center sets "set point" sends message via efferent pathway.Effector picks up respose and feeds back to stimulus.
Positive Feedback Control infrequent events eg damage to lining of blood vessel
Negative Feedback Regular controls where output decreases or shuts off original stimulus and works "opposite"the initial change. eg heating system
Homeostatic Imbalance most disease is regarded as disturbance of Homeostatic
Maintenance of boundaries body keeps the outside via Integumentary system protected from the internal organs etc
Movement Skeletal system propels the body Movement via the internal organs
Metabolism Sum total of all chemical reactions
Excretion Process of removing wastes from the body.
Survival needs of the body Nutients, Oxygen, Water body Temp and Atmospheric preasure
