Cytology Flashcards
Homeostasis
the condition of being in the optimal steady state
Disease
follows loss of homeostasis
Homeostasis
the condition of being in the optimal steady state
Plasma
liquid extracellular fluid (for blood cells)
interstitial fluid
liquid extracellular fluid (living cells)
cytoplasm
intracellular fluid
cell
basic unit of life
tissue
structures formed by the same cell type
organ
groups of different kinds of tissue combined
Organ systems
Groups of organs that together are able to perform soe homeostatic function
Organism
Group of organized organ systems
Circulatory System
Continuously replenishes raw materials and removes waste products of cells, The HEART pumps the blood, the arteries distribute the blood, the capillaries exchange nutrients for waste and the veins collect the blood and return it to the heart
Respiratory System
Brings oxygen into the body where it rapidly enters the blood, transports carbon dioxide (metabolic waste) out of the body
Digestive System
Digests materials passing through the GI tract into absorbable forms in the bloodstream and eliminating the waste, providing the body with nutrients to sustain life
Skeletal System
Supports soft tissues against gravity, protects organs, and supplies blood to cells and important minerals
Muscular System
provides movement with organ systems including the heart (cardiac muscle) and other internal organs with visceral muscle and communication w/ skeletal muscle
Urinary system
purges metabolic waste from the body and keeps water and electrolytes in balance to control blood pressure
Nervous System
allows the body to perceive and respond to the environment and its conditions
Sensory receptors
Communicate information regarding conditions in the internal or external environment to the CENTRAL NERVOUS SYSTEM
Central Nervous System
Assesses the condition and if necessary acts to change them by activating MOTOR EFFECTORS
Motor Effectors
respond to signals with muscle contraction or gland secretion
Endocrine System
control system alongside NERVOUS SYSTEM, exerts control by using blood-borne hormones to produce effects in target cells
Reproductive System
Contributes to the survival of the organism because every organism will ultimately fail and a new one must take its place
Nervous system (control)
Electrochemical control system
