DO NOW
• Complete the 10 mc questions on the handout

QUIZ
• It is now time for a quiz
• Clear off your desks
• You will only have about 10 minutes

GOAL
• To be able to describe the skeletal, muscular & reproductive systems and how their functioning helps the body to maintain homeostasis

REVIEW- Without using notes!
• Describe what role peristalsis plays in the digestive system
• Peristalsis is the squeezing of food by involuntary muscles- it forces the food through the digestive tract

REVIEW- Without using notes!
• How can astronauts digest anything in outerspace, when there is no gravity??
• Peristalsis forces the food through the digestive tract

REVIEW- Without using notes!
• Describe the passage of food through the digestive tract- from beginning to end, what organs/parts does the food pass through?
• Mouth--> Esophagus--> Stomach-->
Small Intestines--> Large Intestines-->
Anus

REVIEW- Without using notes!
• What types of cellular wastes does the excretory system of the body get rid of?
• Water, heat, carbon dioxide, salt, urea

REVIEW- Without using notes!
• What are the 4 major organs that comprise the excretory system? Which ones are organs of excretion and which ones are organs of elimination?
• Lungs, skin, kidneys- excretion
• Large Intestine/ anus- elimination

REVIEW- Without using notes!
• What is the function of the endocrine system?
• Glands secrete hormones that regulate the body’s functions (respond to changes inside and outside of the body)

SKELETAL SYSTEM VIDEO
• What are the 4 major functions of the skeletal system?

QuickTime™ and a
Sorenson Video 3 decompressor are needed to see this picture.

Skeletal System
• GOAL • To protect organs, allow movement, make red & white blood cells
• Examples of Organ Protection:
– brain covered by skull
– heart & lungs covered by ribs

Skeletal System
• Joints • How do bones move?
• 3 type of joints
– Ball & Socket- allows twisting
(hips)
– Hinge- move in one direction
(elbow)
– Slightly moveable- limited movement (vertebra & ribs)

Ball & Socket Joint

Hinge Joint

Skeletal System
• Bones • Blood cells made in marrowhave calcium

Skeletal System
• Cartilage • Softer, flexible bone

Skeletal System
• Ligaments • Holds bone together at joints

Skeletal System
• Tendons • Cordlike tissue that attaches muscle to bone

Muscular System Video
• Describe the 3 types of muscle found in the body and area in which you can find each

QuickTime™ and a
Sorenson Video 3 decompressor are needed to see this picture.

Muscular System Diagram

Muscular System
• GOAL • Allows the body to move
• Muscles only contract (pull)they don’t push

Muscular System
• Types of muscles
• VOLUNTARY (skeletal)
– Can control them
– Are attached to bones
– Work in pairs

Muscular System
• Types of muscles
• INVOLUNTARY (smooth)
– Can’t control them
– Found in blood vessels, organs, digestive tract

Muscular System
• Types of muscles
• Cardiac (Heart)
– Smooth, Involuntary

Reproductive System Video
• What type of gonads are found in the male & female and which cells does each produce?

QuickTime™ and a
Sorenson Video decompressor are needed to see this picture.

Reproductive System
• GOAL • Sex cells combine to produce young
• Ovaries: In females, produce eggs
• Testes: In males, produce sperm

Reviewing what we’ve learned
• What is the job of the skeletal system?
• What is the job of the reproductive system?
• What is the job of the muscular system?

Reviewing what we’ve learned
• Distinguish between the 3 types of joints
• Distinguish between the 3 types of muscles
• What are the major parts of the reproductive system?
