Let’s Take A Look …
Inside the Human Body • Start at 2:50min.
Overview …
1. Respiratory System
2. Circulatory System
3. Nervous System
4. Skeletal System
5. Muscular System
6. Integumentary System
7. Exocrine System
8. Endocrine System
9. Digestive System
10. Lymphatic System
11. Urinary System
Life Sustaining Processes:• Support & Movement• Energy Flow• Regulation• Defense• Waste Management• Gas Exchange• Responds
Comparative Anatomy
• Your body is just like a machine.. Only BETTER..!!
• Think about your body:How is the human body similar to non-living objects… ??
Homeostasis
• Staying healthy keeps our body in balance!!
• Regulation of life sustaining conditions is called Homeostasis
Levels of Organization
• CellsBasic unit of life
• TissuesMade of different cells working together
• OrgansMade of different tissues working together
• Organ SystemsMade of different organs working together
Organisms
BIG IDEA: Working together to achieve homeostasis ….
Topic 2:• Support & Movement
a) Skeletal Systemb) Muscular Systemc) Nervous System
Skeletal System
Structure:
1. Bones
• 206 bones• Store Minerals• Make Blood Cells• Protect Organs• Attachment for muscles
Muscular System
Function:
1. Attaches to bones (movement)
2. Allows movement inside the body (blood, food, urine)
3. Generate body heat
Muscular System
Structure:
1. Skeletal Muscles• 600 muscles attach to bones & move
bones at joints
2. Smooth Muscle• Make tubed organs like intestines, blood
vessels & bladder
3. Cardiac Muscle• Make the heart
Nervous System
Function:• Sends impulse to muscles &
glands
Structures:• Brain• Spinal cord• Nerve cells• Sense organs (Eyes, Nose, Tongue,
Skin)
How to the 3 Systems Work together?
1.Skeletal System2.Muscular System3.Nervous System
• Nerves send an impulse to the Muscles • Muscles contract & pull on Bones• Bones then cause movement at joints
• Nerves also send impulses to cardiac & all smooth muscles.
• Those muscles contract and cause internal movement for urine, blood & food.
