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...

Organism

The 4 main animal tissues…

1. Epithelial body/internal organ covering

2. Muscle act by shortening/lengthening

3. Nervous coordinate body actions

4. Connective supports, protects or connects

cells/tissues

The 4 main animal tissues…

Connections among body systems

Organ systems that coordinate communication1. Nervous system

detects and respondsto ex/internal stimuli

2. Endocrine system secretes hormones

which affect development andreproduction

Connections among body systems

Organ systems that support and move the body3. Skeletal system

protects organs andsupports tissues

4. Muscular system necessary for

movement

Connections among body systems

Organ systems that protect the body5. Urinary system

excretes waste & keeps blood pressure balanced

Connections among body systems

Organ systems that protect the body6. Integumentary system

physical barriers for protection

Connections among body systems

Organ systems that protect the body7. Immune system

protects from infection

Connections among body systems

Organ system that procreates8. Reproductive system

makes subsequent generations

Organ systems that acquire energy

9. Respiratory system exchanges O2 and CO2

10. Circulatory system Transports substances

11. Digestive system breaks down food

The Big 3...
