What’s the function of the skeletal system
-provides shape and support for your muscles
-protects internal organs
-makes red blood cells
What is marrow (skeletal system)
Soft connective tissues found in space in bones
Red-produced body blood cells
Yellow-stores fats
What is cartilage tendon and ligament
Cartilage-reduces friction in as shock absorption
Tendon-connects muscles to bone
Ligament-connects bone to bone
Types of joints
Hinge(knee)
ball and socket (shoulder and hip) fixed(skull)
Gliding (wrist and ankle)
Pivot(neck)
What is the function of the muscular system
Provides movement and support for the skeleton
What are the levels of organization in living things?
Cell → Tissue → Organ → Organ System → Organism.
What is the function of the circulatory system?
Moves blood, oxygen, and nutrients through the body.
What is the function of the respiratory system?
Takes in oxygen, releases carbon dioxide.
What is the function of the digestive system?

What is the integumentary system
Skin, hair, nails — protects the body
What is the function of the endocrine system?
Produces hormones to control growth and metabolism.
What is the reproductive system?
Creates offspring (new life).
How do the respiratory and circulatory systems work together?
Respiratory brings in oxygen → circulatory carries oxygen to cells.
: How do the digestive and circulatory systems work together?
Digestive breaks down food → circulatory carries nutrients to cells
How do the muscular and skeletal systems work together?
Muscles pull on bones to help you move.
What system are red blood cells part of, and what do they do?
Circulatory
• Function: Carry oxygen from lungs to body cells and carbon dioxide back to the lungs.
What system are white blood cells part of, and what do they do?
Immune (and Circulatory)
• Function: Fight infection and destroy harmful germs.
What system are skin cells part of, and what do they do?
Integumentary
• Function: Protect the body from germs, regulate temperature, and prevent water loss.
What systems use epithelial cells, and what do they do?
Digestive, Respiratory, Integumentary
• Function: Line organs and protect or absorb materials.
What system do fat cells help?
Back
Integumentary / Endocrine
• Function: Store energy and cushion organs
