Transcript of The Body Systems

The
Skeletal System Your skeletal system is your body's framework that gives strength and shape. You use your skeletal system to do everyday activities, such as sitting, standing, walking, etc. Body Parts Problems of Your Skeletal System 1. Arthritis, the inflammation of a joint.

2. Osteoporosis, a condition that includes symptoms of brittle and porous bones. This can develop by long-term deficiencies of calcium and certain hormones, and lack of exercise.

3. Scoliosis, a sideways curve of the spine.

4. A fracture, is a break in a bone caused by an injury. 1. Be physically active to increase bone mass.

2. Eat foods high in calcium and phosphorus, calcium is essential for building and maintaining strong bones, and phosphorus combine s with calcium to give bones rigidity.

3. Sit, stand, and walk with straight posture and provide correct arch support. The
Muscular System Function Muscles pull on the joints, allowing us to move. Performs other functions, so we can grow and remain strong. The Muscular system allows you to chew food and move it through the digestive system. By: Lydia Pack The Body Systems What Doctor Would Treat You? Caring for the Skeletal System Orthopedic Surgeons repair broken bones and replace joints.

Radiologists examine the skeletal system.

Physical therapists help with joint pain. Function Joints- Occur where 2 bones meet. Make the skeleton flexible and movement would be impossible without them.
Cartilage- A flexible, rubbery substance in our joints, supports bones and protects them where they rub against each other.
Ligaments- Bones are fastened to other bones by ligaments. They are long, fibrous straps.
Tendons- Tough bands of tissue that attach your muscles to bones, allow the muscles to pull on bones. Caring for the Muscular System 1. Be physically active, the more use of the muscles, the more efficient the muscles become.

2. Warm-up before physical activity, it helps prevent muscle injury and increases muscle flexibility.

3. Maintain a healthy body weight, extra body weight can put strain on the body muscles. What Doctors Would Treat You? A Rheumatologist is trained in treating diseases of joints, bones, and soft tissues, including muscles.

An Orthopedist is a doctor that is trained to treat the musculoskeletal (a combination of the muscle and skeletal) system. The
Circulatory System 1. A pulled or torn muscle, that has been torn away from the bone or has been damaged within.

2. A muscle strain, soreness from overuse. Caused by small tears to the muscle or tendon.

3. Muscular Dystrophy, a disorder that is usually inherited. It causes the skeletal muscle to weaken. Problems of the Muscular System Skeletal Muscle- Attached to bone, mostly in the legs, arms, abdomen, chest, neck, and face, enables you to move body.

Smooth Muscle- Muscle found in organs and in blood vessels and glands You don't control the contraction of these muscles, they are involuntary.

Cardiac Muscle- Muscle found only in the walls of your heart. Contracting and relaxing continually, your cardiac muscle enables your heart to pump blood. Body Parts Function Organs and tissues that transport essential materials to body cells and remove their waste products. Body Parts Arteries- Blood vessels that carry blood away from the heart to other parts of the body.

Veins- Blood vessels that carry blood from the body back to the heart.

Capillaries- Tiny tubes that carry blood from the arteries to the body's cells, and then back to the veins. Problems of the Circulatory System 1. Hypertension, a condition where blood pressure is constantly higher than normal.

2. A stroke that results from blood clots that block vessels in the brain.

3. Heart attack, which is caused by the blockage of the flow of blood to head.

4. Hemophilia, blood plasma that does not contain substances that help the blood to clot. Caring of the Circulatory System 1. Limit fat in your foods, dietary fat can cause fatty deposits to form and increase blood pressure.

2. Get regular physical activity, it can strengthen your heart muscle, allowing your heart to pump more blood with each beat.

3. Avoid tobacco, nicotine in tobacco narrows arteries, requiring blood pressure to be higher to circulate blood through the body. What Doctors Would Treat You? Cardiologists are doctors that specialize in the heart.
Vascular doctors specialize in veins and arteries
The
Immune/Lymphatic System Function The Immune System's function is to defend people against germs and microorganisms every day keeps people healthy and prevent infections.
The Lymphatic's System's function is to collect extra lymph fluid from body tissues and return it to blood. If it didn't, the lymph fluid would build up in the tissues and would swell. Body Parts Lymph nodes spread throughout the body, it filters out all the dead bacteria, viruses, and other dead tissue.

Lymphatic vessels are a network of channels that carries lymphocytes. Problems of the Immune/Lymphatic System 1. Immunodeficiency disorders occur when part of the immune system is not present or is not working properly.
2. Lymphadenopathy occur where the lymph nodes become swollen or enlarged.
3, Allergies result from the immune's system overreaction to a non-threatening foreign substance. Caring for the Immune/Lymphatic System 1. Eat a well balanced diet, low-fat foods that are high in fiber have beneficial effects.

2. Be active, that can help protect immune function.

3. Manage stress, stress triggers the overproduction of neurochemicals in the brain that can lower immune function. What Doctors Would Treat You? Infectious disease, allergy and immunology, oncology and hemotology, and rheumatology specialists have a partial focus on the immune/lymphatic system as well.
