Intro Flashcards
Histology
microscopic anatomy: structure of tissues and their organization into organs
Gross anatomy
macroscopic anatomy: structures that can be examined without a microscope
Anatomy is the Study of
body structure: external and internal structures and physical relationships between body parts
Levels of body organization
chemical molecular level (atoms in combination, complex protein molecule, protein filaments) to cellular level to tissue level to organ to organ system to organism
Organ Systems of the Body (11)
SMILERCRUD: skeletal, muscular, intergumentary, lymphatic, endocrine, respiratory, cardiovascular, reproductive, urinary, digestive
Skeletal System (3)
supports and protects tissues, stores minerals, forms blood cells - axial and appendicular skeleton
Integumentary System (2)
protects against environmental hazards, helps control body temp - skin, glands, nails, hair
Muscular System (3)
Generates locomotion, provides support, produces heat
Cardiovascular System (2)
transports cells and dissolved materials (nutrients, wastes, gases), regulates body temp
Nervous System (2)
immediate response to stimuli, inegrates activities of organ systems
Endocrine System (1)
long term regulation of other organ systems
Lymphatic System (2)
defends against infection and disease, returns tissue fluid to blood stream
Respiratory System (1)
exchanges gas between air and circulating blood
Digestive System (2)
processes food, absorbs nutrients
Urinary System (2)
eliminates excess water, salts and waste products, filters blood
