Anatomy & Physiology Flashcards
What is the difference between anatomy & physiology?
Anatomy is the study of body structure and physiology is the study of body functions
What are the Subdivisions?
Surface, Gross, Developmental, Histology, Pathology , Cytology
A balance in the body’s internal environment is…..
Homeostatis
Levels of Organization?
atom, cell, molecule, tissue, organ,system, organism
Six important life processes of an organism?
metabolism, responsiveness, movement, growth, differentiation, reproduction
Feedback System consist or which three things?
Receptor, Effector, Control Center
Receptor
monitors changes in controlled conditions and sends inputs to control center
Effector
receives output from the control center and produces a response or effect the controlled conditions
Control Center
sets the range value to be maintained- usually this is done by brain
Positive feedback system consist of what?
strength or reinforces a change in ones body ex child birth
Negative feedback system
reverses a change in the controlled condition ex; blood pressure or body tempature
Integumentary system consist of
skin, nail, hair
Skeletal system
bones and joints
Muscular system
muscles, maintaining posture, generate heat
Nervous System
brain, spinal cord, nerves and, sensory organs
Endocrine system
hormones
Cardiovascular system
heart and blood vessel- regulates body temp
Lymphatic system
lymphatic fluid, lymph nodes and lymphocytes,tonsils, spleen, thymus gland-filters blood and transports fats ans proteins
Respiratory system
upper airway trachea, bronchi and lungs - Exchanges o2 and eliminates co2
Digestive system
esophagus, stomach and intestines and accessory organs - eliminates waste
Urinary system
kidneys, ureter, bladder, urethra - excretions of waste
Reproductive system
testicles, penis, testosterone,ovaries, vagina, mammary glands, uterus
