Introduction to Anatomy and Physiology

study of structure of the body and how parts relate to one another Anatomy
study of the function of the body Physiology
study of the large body structures that can be easily examined without any type of magnification Gross Anatomy
all structures in one area are studied regional
studied system by system systematic
study structures with aid of magnification microscopic anatomy
study the cells of the body cytology
study of the tissues histology
Structural changes in the body cells, tissues, organs caused by disease Pathological Anatomy
Structural changes in an individual from conception through old age Developmental Anatomy
study usually divided by system Physiology
What a structure is capable of doing depends critically on its specific architecture Principle of Complementary of structure and function
Hierarchy of structural of structural organization Atom-cells-tissues-organs-organ system-organism
system external body covering, protection, contains receptors Integumantary System
protects and supports body organs, provides framework for muscles to cause movement skeletal System
all body muscle and aids for muscle movement Muscular System
fast acting control system nervous System
Entirely of glans that secrete hormones to control body processes, slow acting control system Endocrine System
carries oxygen and carbon dioxide, nutrients, wastes to and from all body systems Cardiovascular System
picks up fluid leaked from blood vessels and returns it to the blood lymphatic System
protects body against foreign invaders, only system without organs, only cells Immune System
known as urinary system, removes nitrogenous waste, retaining water Excretory System
supplies oxygen to blood and gets rid of waste carbon dioxide Respiratory System
breaks down food food so it can be absorbed; remove waste from bpdy Digestive System
helps reproduce an offspring Reproductive System
Survival needs Nutrients, water, oxygen, water, body temp, atmospheric pressure
Important life processes Maintenance of boundaries: cell membrane,skin Movement- muscles, blood, food, urine Responsiveness- sensitivity
set point at what variable is to be maintained Control Center
sensor that monitor environment Receptors
provides the means to control center effector
Control Center sends out signals to decrease Negative Feedback
Control Center send out signals to increase stimulus or increases effects Positive feedback
Inability to maintain homeostasis Most diseases are caused by it homeostatic imbalance
