  1. Human Body

  2. Skeletal and Muscular System • Bones give us shape, support, and protection • Born with 300 bones, but as you age, some bones fuse together, an adult has 206 bones • Largest bone: femur • Smallest bone: stapes (located in your ear)

  3. Skeletal and Muscular System • Bones cannot move on their own, they need muscle to work.

  4. Skeletal/Muscular System • Joints help humans swivel, bend, curl, pivot, and turn. • Joints are points where 2 or more bones are joined together by muscles.

  5. Circulatory System • What is the largest muscle in the body? • What does the heart do? • Where does blood go? • Arteries are red because they are carrying oxygen. • Veins are blue because they do not have oxygen.

  6. Repertory System • We breathe by taking in air through our nose and mouth. • The air then passes through the trachea (windpipe) into the lungs. • The lungs swap oxygen for carbon dioxide with the blood stream. • The diaphragm is a muscle that helps push out my lungs when they are filling up with air. • The diaphragm also help let my lungs back in to squeeze out the air.

  7. Digestive System

  8. Digestive System • Canines (sharp and pointy shapes used for cutting and tearing) • Incisors (big, flat wedge shapes used for biting off food) • Bicuspids or premolars (2-pointed shapes for grinding) • Molars (flat, squared shapes used for grinding)

  9. Digestive System • After the mouth, the food passes through a tube in your throat called the esophagus. • The food passes through the esophagus into the stomach. • Muscles move the walls of the stomach to mash up the food.

  10. Digestive System • The small intestine squeezes the food through a 20 foot long tube that is coiled up in the body. • The small intestine pulls nutrients out of the food and is taken into the bloodsteam. • The large intestine takes the water out of the food and pushes out the solid waste.

  11. Nervous System • The brain contains nerves that send messages all over the body through other nerves. • The brain is part of the central nervous system along with the spinal cord. • The spinal cord is a bundle of nerves that relay messages from the brain to different parts of the body. • The brain also receives and process messages from our senses.

  12. Endocrine System • A system of glands that helps the body function. • It contains a group of glands that release hormones (special chemicals) into the body. • Controls: body temperature, sleep, hunger, growth sweat, “fight” or “flight”, male or female characteristics, etc
