43 - Learning Targets
1. I can identify the main function of each human body system.
2. I can list the major organs (parts) present in each human body system.
3. I can analyze diagrams of human body systems.
44 – Parts of the Digestive System
Mouth – Teeth and Saliva
Esophagus
Stomach
Intestines Pancreas
44 - Digestive System Main Function
• Breaks down food through mechanical and chemical digestion
• Food breaks down into nutrients that can be absorbed by the blood.
45 - Skeletal System
Parts: • Bones, Ligaments, JointsMain Function: • Protects internal organs • Works with muscular system
to create locomotion• Bones produces blood cells!
46 - Muscular System
Parts: • Skeletal, smooth, cardiac musclesMain Function: • Works with skeletal system to
create locomotion• Maintains posture• Provides strength
47 – Parts of the Nervous system
BRAINSPINALCORD
NERVES
47 - Main Function Nervous system
• Controls all body functions
• Receives signals from 5 5 senses (INPUT)
• Sends signals to body (OUTPUT)
BRAIN
SPINALCORD
NERVES
48 – Parts of the Respiratory System
Nose Mouth
Throat/Trachea
Lungs
48 – Main Function Respiratory System
•Exchange gases with atmosphere•Absorb in oxygen, excrete carbon dioxide•Create ENERGY!
49 – Parts of the Circulatory System
Heart
Artery (Away from heart)
VeIN (IN to heart)
49 – Main Function Circulatory System
• Circulates (pumps) blood and nutrients around the body
• Arteries carry blood with Oxygen away from the heart, to the body.
• Veins carry blood with Carbon Dioxide back to the heart from the body.
50 - Excretory SystemKidneys
Bladder
Main function: • Filter blood• Remove waste from
body
50 - Endocrine System
Parts: glands (tissues that release hormones/chemicals)
Main function: releasing hormones that control growth, metabolism, reproduction
