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, Joints Main Function: Protects internal organs Works with muscular system to create locomotion Bones produces blood cells!

46 - Muscular System Parts: Skeletal, smooth, cardiac muscles Main Function: Works with skeletal system to create locomotion Maintains posture Provides strength

47 – Parts of the Nervous system

47 - Main Function Nervous system Controls all body functions Receives signals from 5 5 senses (INPUT) Sends signals to body (OUTPUT)

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 AA A rtery ( A way from heart) Ve IN ( 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 System Kidneys 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
