Chapter 1 Flashcards
Physiology
The science of body functions
Anatomy
The science of structure and its relationships
Order of chemical structures
Chemical- cellular- tissue- organ- system- organism
Integumentary system
Skin and its structures that help to regulate body temp and protect the body
Nervous system
Sense organs that help regulate body activities through nerve impulses
Skeletal system
All bones and joints that support and protect the body
Endocrine system
All glands and tissues that regulate body activities through hormones
Muscular system
Skeletal muscle tissue the allows you to move maintaining posture and produces heat.
Cardiovascular system
Blood heart and blood vessels carries oxygen and nutrients to cells
Lymphatic system and immunity
Returns tissue fluid to blood and produces immunity structures and agents
Digestive system
Organs of gastrointestinal tract that achieve physical and chemical breakdown of nutrients and eliminate solid waste
Respiratory system
Lungs and air passageways that transfers oxygen from air to blood
Urinary system
Kidneys, bladder and such produces, stores, and eliminates urine regulates the chemical composition of blood
Reproductive system
Gonads that produce gametes that unite to form a new organism and release hormones to regulate reproduction and other body processes
Growth
Increase in body size (cell body size)
Differentiation
The process of changing Unspecialized cells into specialized cells.
Receptor
Body structure that monitors changes in a controlled condition and sends input (information) to a control center.
Control center
Receives input and generates output
Effector
Receives output and produces a response
Negative feedback
Reverses a change in a controlled condition (childbirth)
Positive feedback
Strengthens a change in a controlled condition (blood clotting)
Symptoms
Subjective changes in the body ( you can’t see them)
Signs
Objective changes (you can see them)
Anatomical position
Head stands erect, facing the observer, level head, eyes forward, feet are flat on the floor directed forward, arms at side, palms forward.
