1. AMOCTOBSO & Systems pg. 264 - 267

2. AMOCTOBSO • Animals are made up of specialized cells working together as systems Cells Tissues Organs Body systems Organism

3. AMOCTOBSO • Systems of systems make up whole organisms... Organelles Atoms Cells Molecules Body/Organ Systems Organs Tissues Organism

4. Connections among body systems • Organ systems that coordinate communication • Nervous system • detects and respondsto ex/internal stimuli • Endocrine system • secretes hormoneswhich affect development andreproduction

5. Connections among body systems • Organ systems that support and move the body • Skeletal system • protects organs andsupports tissues • Muscular system • necessary for movement

6. Connections among body systems • Organ systems that protect the body • Urinary system • excretes waste & keeps blood pressure balanced

7. Connections among body systems • Organ systems that protect the body • Integumentary system • physical barriers for protection

8. Connections among body systems • Organ systems that protect the body • Immune system • protects from infection

9. Connections among body systems • Organ system that procreates • Reproductive system • makes subsequent generations

11. The Big 3... • Organ systems that acquire energy • Respiratory system • exchanges O2 and CO2 • Circulatory system • Transports substances • Digestive system • breaks down food

12. Homeostasis • The body MUST maintain a stable internal state • We call this process “homeostasis” This example shows how negative feedback regulates room temperature. In negative feedback, sensors detect a change and relay this to a control centre, which reverses the change and restores balance.
