LT 3.4 Flashcards
LUNG VOLUME INCREASES AND RIB CAGE EXPANDS. WHILE DIAGPHRAGM CONTRACTS (MOVES DOWN). AIR PRESSURE DROPS
INSPIRATION
LUNG VOLUME DECREASES, RIB CAGE RETRACTS. DIAPHRAGM RELAXES (MOVES UP). AIR PRSSURE INCREASES
EXPIRATION
LUNGS RISES TO CAUSE INFALTION
INHALATION/INSPIRATION
LUNGS REDUCES CAUSING DEFLATION
EXHALATION
IS THE EXCHANGE OF GASES BETWEEN THE CELLS AND THEIR ENVIRONMENT
RESPIRATION
NETWORK OF ORGANS THAT ARE RESPONSIBLE FOR GETTING OXYGEN FROM THE ATMOSPHERE AND HELPS YOU BREATHE
RESPIRATORY SYSTEM
INCLUDES INHALATION AND EXHALATION AND IS THE MAIN FUNCTION OF THE RSPIRATORY SYSTEM
I. PULMONARY VENTILATION& GAS EXCHANGE
(FUNCTION OF THE RESPIRATORY SYSTEM) ABDOMINAL COMPRESSION DURING URINATION, DEFECATION PASSING THE FECES, AND PARTURITION (CHILDBIRTH)
II. ASSISTANCE
(FUNCTION OF THE RSPIRATORY SYSTEM) COUGHING AND SNEEZING (SELF-CLEANING REFLEXES)
III. CLEANING
(FUNCTION OF THE RESPIRATORY SYSTEM) AIR MOVES THROUGH THE LARYNX TO PRODUCE SOUND
IV. SOUND PRODUCTION
(FUNCTION OF THE RSPIRATORY SYSTEM) DURING INHALATION (OLFACTORY EPITHELIU-SENSE OF SMELL)
V. OLFACTION
(FUNCTION OF THE RSPIRATORY SYSTEM) (coarse hairs, goblet cells-fight bacteria, mucus-keeps epithelium from drying out & create a lining which secretes lysozymes to fight bacteria)
VI. DEFENSE
IN INTERCOSTAL MUSCLES (EFFECTS) THE RIBCAGE MOVES UPWARDS AND OUTWARDS
IN INTERCOSTAL MUSCLES (EFFECTS) THE RIBCAGE MOVES DOWNWARDS
AIR SACKS FOR GAS EXCHANGE
ALVEOLI
SURROUNDED BY CAPILLARIES (BLOOD VESSELS) -EXCHANGE OF GASES BETWEEN THE LUNGS AND CAPILLARIES
