SBI4U - Homeostasis
Homeostasis Introduction - Summary of Body Systems
System Structures Functions
Respiratory Mouth, nose, lungs, Gas exchange, eliminate
trachea, bronchi, waste (CO2), obtain O2, keep
bronchioles, alveoli air warm and moist,
immunity/defense
Circulatory Heart, blood, blood Circulate blood (with
vessels (arteries, veins, nutrients like O2 and
capillaries) glucose), immunity (white
blood cells), maintain body
temp.
Digestive Mouth, esophagus, Break down, process and
stomach, small absorb nutrients; reabsorb
intestines, large water; hormone production
intestines (colon) , liver, (insulin and glucagon);
gallbladder, pancreas detoxification by liver
Nervous Brain, spinal cord, Sense and respond to
nerves, sensory organs external environment; high
(eyes, ears, nose) speed communication to
and from all body parts,
voluntary movement,
thinking, reflexes, emotion
Muscular 650+ muscles (smooth, Coordinated
skeletal and cardiac) motion/movement,
support/structure
Skeletal 200+ bones, bone Coordinated
marrow, ligaments, motion/movement,
tendons, cartilage support/structure, blood cell
production
