Ch 1: Organ Systems Flashcards
Anatomy vs Physiology
Anatomy: study of body structures and their relationships to one another
Physiology: study of function of body structures
Branches of Anatomy
Gross Anatomy: structures that can be seen with the naked eye
Embryology: development of the body’s form
Microscopic: cytology and histology
[cell / tissues]
How many organ systems function together to maintain homeostasis

11a. Male reproductive
11b. Female reproductive
Integumentary System
Provides protection, regulates body temp, prevents water loss
(site of cutaneous receptors, synthesis of V-D)
Skeletal System
Provides support, protection, homeopoiesis, stores calcium/phosphorus, site for muscle attachment
Muscular System
Provides body movement, generates heat when muscles are moved
Nervous System
Regulatory System
Controls body movement, responds to sensory stimuli
(responsible for consciousness, intelligence, memory)
Endocrine System
Consists of glands and cell clusters that secret hormones
Master Endocrine Gland
Pituitary Gland
Cardiovascular System
Cardio: heart
Vascular: vessels
everything to do with vessels that attach to the heart
Lymphatic System
Transports and filter lymph, initiates an immune response when necessary
What is lymph?
interstitial fluid transported through lymph vessels
What is interstitial fluid?
Main component of extracellular fluid
What is extracellular fluid?
All body fluid outside of the cells
