Close up on: Body Systems By: Judy Vidales Period: 1
Skeletal System Purpose: To give our body shape. Main parts:
Bones: The skeletal system is able to keep the bones balanced and able to move and bend. Cartilage: Cushions your bones so they don’t rub or hit each other. Joints: Occur when two bones meet. Without them, there would be no movement. Ligaments: Surround and bind joints together. They control or restrict movement and link bones together. Relations to other Systems:
Circulatory: The skeletal system, including the rib cage, protects vital organs and the blood that the circulatory system is controlling. Respiratory: The bones protect the lungs that are a big part of the respiratory system. Pathogen:
Osteoporosis: Highly decreases the amount of bone, reducing the strength of the bones.

Muscular System Purpose: Assist in movement of mobility of the body. Main parts:
Cardiac muscle: Helps heart pump blood throughout the body. Tendons: Connective tissues attach skeletal muscles to bone, skin and other muscles. Smooth muscles: Slow and contract by smooth muscle lining tubes to digest. Relations to other Systems:
Skeletal: Bones give the muscle support and help them move. Digestive: Food is pushed down by smooth muscle lining tubes to digestion. Pathogen:
Stroke: The brain shuts down all of the muscles.

Circulatory system Purpose: Transporting materials throughout the entire body. Main parts:
Heart: Pumps blood throughout body. Atrium: Collects blood from the rest of the body. Ventricle: Pumping blood out of the heart and into the rest of the body. Arteries: Largest and strongest blood vessels. Blood: Carries oxygen to -muscles. Red blood cells; Can live 80-120 years. Relations to other Systems:
Respiratory: The oxygen flows inside the blood and to the heart. Muscular: As blood pumps through your body to move your muscles. Pathogen:
Asthma: Causes lungs to contract when there is not enough oxygen to support the blood.

Respiratory System Purpose: To transport air into the lungs and to facilitate the diffusion of oxygen into the blood stream. Upper respiratory tract:
Nose Pharynx Larynx Lower respiratory tract:
Bronchial tree Trachea Lungs Relations to other Systems:
Muscular: Providing oxygen so muscles can move. Nervous: The brain needs oxygen to work. Pathogen:
Bronchitis: An inflammation of the lining of the bronchial tubes, the airways that connect the trachea to the lungs.

Digestive System Purpose: To break food down into smaller parts. Main parts:
Stomach: Breaks down food to release nutrients, then passes to intestines. Small intestine: Soaks up nutrients, vitamins, minerals, sugars, carbs etc,. Large intestine: Further soaks nutrients and filters waste to exit the body. Gall bladder: Stores bile to break down food and absorbs vitamins D,E,K and A Liver: Processes and collects nutrients from blood, stores vitamins, iron, carbs and fats. Controls sugar levels in the blood. Saliva: Makes food softer, easier to break down, has lots of enzymes to start digestion. Pancreas: Makes digestive juices with 15 chemicals to break down food and regulates sugar levels. Mouth: Breaks down food by crushing it with teeth, making it easier to swallow and digest. Esophagus: Transports chewed up food to stomach using the lining of muscles. Relations to other Systems:
Respiratory: In charge of getting oxygen to muscles. It keeps you alive from the fuel that the digestive system sends. Circulatory: Gets the absorbed nutrients distributed through your body. Pathogen:
Staphylococcal: Food poisoning.

Nervous System Purpose: Helps all the parts of the body to communicate with each other. Main Parts:
Nerves: They are all around your body, like messengers to the brain. Brain: The control center of your body. Spinal cord: Path that the nerves are sent through to the brain. Relations to other systems:
Digestive:You are eating and breaking down food to go your stomach, the brain makes sure this runs smoothly and you don’t choke. Musculoskeletal: The brain controls the movement of the bones and muscles. Pathogen:
Multiple Sclerosis: Hardens plaque of degeneration of the insulating layer of nerve fibers in the nervous system. Creates an unbalanced system.
