1. Body Systems Notes

2. Body System Notes
We will be learning about 8 different body systems. Many of these systems work together for a similar function. Please use this information to work on your project.

3. Major Parts
Bones 
Joints
Ligaments
Cartilage
Skeletal System

4. Skeletal System Structure (What is is) Bones have a hard outer layer.
Bones attach to each other through ligaments and joints
Bones attach to muscles through tendons.
Skeletal System

5. Skeletal System Function (What it does) Protection Movement Storage
Support
Red blood cell production
Skeletal System

6. Muscular System Major Parts Skeletal Muscle Smooth Muscle
Cardiac Muscle
Muscular System

7. Muscular System Structure (What is is) Involuntary and voluntary
Fibrous Tissue
Muscular System

8. Muscular System Function (What it does) Used for movement
Skeletal muscle can be controlled, smooth and cardiac muscle cannot.
Muscular System

9. How do these two systems interact (useful for your project)
Major Parts for Skeletal System
Bone -Cartilage -Ligaments Joints
Major Parts for Muscular System
Skeletal Muscle -Smooth Muscle -Cardiac Muscle
How do these two systems interact (useful for your project)

10. Cardiovascular/ Circulatory System
Major Parts
Heart
Blood
Blood vessels
(Lymphatic System)
Cardiovascular/ Circulatory System

11. Cardiovascular/ Circulatory System
Structure (What it is)
Heart is a muscle in constant motion
Blood transports oxygen, hemoglobin, hormones and nutrients
Vessels lined with smooth muscle
Cardiovascular/ Circulatory System

12. Cardiovascular/ Circulatory System
Function (What it does)
Heart pumps blood through veins
Delivers oxygen from lungs through hemoglobin in red blood cells
Maintains homeostasis
Cardiovascular/ Circulatory System

13. Cardiovascular/ Circulatory System
Notes (on left side of notebook, if you’ve run out of room, turn the page and still use the left side.)
Heart-cardiac muscle, right side pumps oxygen poor blood to the lungs. Left side pumps oxygen-rich blood to the body. Made up of four chambers, valves cause “lub-dub” sound.
Blood- connective tissue, serves as a transport system through miles of vessels in the body
Blood vessels- 3 kinds. Artery-> carries blood away from the heart. Capillary->Tiny blood vessel exchanges between body cells and blood. Vein->carries blood back to the heart.
Cardiovascular/ Circulatory System

14. Major Parts
Nose
Larynx
Trachea
Bronchioles
Alveoli
Respiratory System

15. Structure (What it is) Respiratory System
Air travels from nose and mouth through tubes
Lungs are like balloons
Alveoli are tiny sacs
Respiratory System

16. Function (What it does)
Takes in Oxygen for blood
Releases waste in the form of Carbon Dioxide
Respiratory System

17. Oxygen travels from the nose/ mouth to the pharynx, the larynx, trachea, bronchioles, and alveoli.
The alveoli are tiny sacs that diffuse oxygen into blood vessels located there.
Respiratory System

18. How to keep the systems healthy

19. Lung health

20. Interaction

21. Digestive System Major Parts: Mouth Esophagus Stomach Small Intestine
Large Intestine
Rectum
Anus
Digestive System

22. Digestive System Structure (What it is) Teeth and saliva in the mouth
Esophagus: muscle tube
Stomach: muscular organ
Intestines: smooth muscle tissues
Rectum and anus are at the end of the system for feces
Digestive System

23. Digestive System Function (What it does)
Mechanical Digestion (chewing)
Chemical Digestion (saliva, acid, and enzymes)
Breaks down food into basic nutrients
Package unused digestive wastes
Digestive System

24. Digestive System Additional Notes:
-Mechanical and chemical digestion happens in the mouth. Food travels down the esophagus to the stomach.
-The stomach is full of acids and enzymes. Intestines absorb water and nutrients for energy…and make poop.
Digestive System

25. November 12th new due date, things need to be ready that day, presentations to come in days after.
Project Due Date

26. Excretory System Major Parts: Skin (largest organ) Kidneys Bladder
Lungs
Excretory System

27. Excretory System Structure (What it is) Skin has sweat glands
Kidneys filter
Bladder: muscular and elastic
Lungs deflate
Excretory System

28. Excretory Systems Function (What it does) Regulates body temperature
Filters food and water
Excretes waste
Excretory Systems

29. Excretory System Additional Notes:
Sweat glands in skin regulate body temperature.
Kidneys and bladder excrete waste.
Lungs exhale CO2
Excretory System

32. Me: Immune system, why do I have a fever?
Immune System: Well, the bacteria can’t survive outside 100 degrees for long so I thought I’d raise the temperature to kill them off!
Me:
Immune system:
Immune System:
Me: We also can’t survive outside 100 degrees for long.
