AMOCTOBSO & Systems MH: 86 – 89 & 96
AMOCTOBSO • Animals are made up of specialized cells working together as systems Cells Tissues Organs Body systems Organism
AMOCTOBSO • Systems of systems make up whole organisms... Organelles Atoms Cells Molecules Body/Organ Systems Organs Tissues Organism
The 4 main animaltissues… • Epithelial • body/internal organ covering • Muscle • act by shortening/lengthening • Nervous • coordinate body actions • Connective • supports, protects or connects cells/tissues
Connections among body systems • Organ systems that coordinate communication • Nervous system • detects and respondsto ex/internal stimuli • Endocrine system • secretes hormoneswhich affect development andreproduction
Connections among body systems • Organ systems that support and move the body • Skeletal system • protects organs andsupports tissues • Muscular system • necessary for movement
Connections among body systems • Organ systems that protect the body • Urinary system • excretes waste & keeps blood pressure balanced
Connections among body systems • Organ systems that protect the body • Integumentary system • physical barriers for protection
Connections among body systems • Organ systems that protect the body • Immune system • protects from infection
Connections among body systems • Organ system that procreates • Reproductive system • makes subsequent generations
The Big 3... • Organ systems that acquire energy • Respiratory system • exchanges O2 and CO2 • Circulatory system • Transports substances • Digestive system • breaks down food
