1. { Body Systems

2. The Body systems: 1.Skeletal 2.Circulatory 3.Digestive 4.Excretory 5.Muscular 6.Nervous 7.Respiratory

3. The skeletal system is made up of the: Skull Spinal column Humerus Ribs Pelvis Femur Tibia Fibula The main purpose: To support your body Protect internal organs Helps with movement

6. Circulatory System: The main purpose: Move blood throughout the body. The circulatory system includes: Heart Organ that pumps blood through blood vessels. Arteries Largest blood vessels that send blood to your body. Veins Carry blood back to the heart. Capillaries Small blood vessels that carry blood from the arteries to the body.

8. Digestive System: The organs involved in the Digestive system: Mouth Esophagus Liver Gallbladder Stomach Pancreas Small intestine Large intestine Rectum Anus

9. The process food goes through during digestion: When you chew and then swallow the food moves down the esophagus. Bile from the liver goes to the small intestine through the gallbladder. From the esophagus, food moves to the stomach and then the small intestine. Nutrients move from the small intestine to the blood. The rest goes to the large intestine. The large intestine takes out the water. The solid waste continues on. Solid waste moves from the rectum out of the body through the anus.

11. Respiratory System: The organs involved in the respiratory process: Bronchi Capillaries Nose Mouth Trachea Lungs

12. The Respiratory System Process: 1.Oxygen enters through the mouth and nose. 2.Oxygen is transported through the trachea down the bronchi tubes. 3.Oxygen is taken into the lungs. 4.Oxygen is converted to carbon dioxide and travels through the path back out of the nose and mouth.

14. Muscular System: Three types of muscles: 1.Cardiac Thick, automatic muscle that pumps blood. 2.Smooth Layers of muscle all over your body; for breathing sneezing. 3.Skeletal Muscles that move bones, voluntary, provide strength.

16. Excretory System: The main organs involved in the Excretory system: Lungs What: Water vapor and carbon dioxide How: When you breathe out, your lungs release water vapor and carbon dioxide. Urinary system What: Urine (waste cells makes) How: Waste in the blood goes to your kidneys, forms urine, and is released. Skin What: Sweat (perspiration) How: Perspiration exits the body through the sweat glands.

18. Nervous System: The main purpose of the Nervous System: Nerves Carry messages from and to parts of your body. Spinal cord A long bundle of nerves that carry messages to and from your brain. Brain Body’s control center that processes information and stores memories.

20. Important Organs in the Body: Skin Largest organ, protects tissues, bones, and other organs. Brain Processes information and stores memories. Heart Pumps blood through the body. Lungs Assist the body for respiration. Stomach Contains food and mixes it with juices. Liver Makes bile, an important digestive liquid. Intestines Removes nutrients and water from digested food. Kidney Where wastes in blood collects.
