6.- Muscular System - Diseases

Diseases:

Dermatomyositis: Is a disease that affects the skin and muscle. The characteristics of dermatomyositis are skin rashes, muscle weakness and inflammatory myopathy or inflamed muscles. Dermatomyositis can affect adults and children.

Symptoms:
- Muscle pain
- Muscle tenderness
- Fatigue
- Weightloss

Rhabdomyolysis: Is a disease that destroys skeletal muscle. This can be caused by a muscle injury. If you have a lot of myoglobin, is the protein that stores oxygen in the muscles, it can damage the kidneys.

Symptoms:
- General weakness
- Muscle tenderness
- Dark or red urine
- Muscle stiffness

Polymyositis: It is a degenerative and inflammatory disease in nature. It affects the tissue that cause weakness and muscle atrophy. commonly affects adults aged 30 to 50 years. They develop gradually over weeks or months.

Symptoms:
- Muscular weakness
- Joint pain
- Fatigue
- Weightloss

6.- The Muscular System - Parts Of The System

Parts Of The System:

The three types of muscles:

- Skeletal muscle: This muscle creates any kind of movement. There are more than 600 skeletal muscles and constitutes 40% of body weight of our body.
All body muscles work together to move the skeleton and are voluntary, controlled by conscious thought.

- Cardiac Muscle: Conforming the walls of the heart and pumps blood to the whole body. This type of muscle creates electrical impulses that produce heart contractions can affect hormones and the nervous system stimuli, such as when our heart rate increases is when we are afraid.

- Smooth Muscle: It is composed of hollow organs such as respiratory ducts, blood vessels, stomach ... Just as the heart muscle smooth muscle also contracts with stimuli and nerve impulses.

6.- The Muscular System - General System Function

General System Function:


The muscles are attached home every bone in his body. Our body has about 700 muscles. The heart has muscles that allow pump blood throughout the body.
There are three main types of muscles in the body.
The visceral muscles help control the functioning of the organs. Cardiac muscles control the functioning of the heart. Skeletal muscles are attached to bones and help the body to move.

5.- The Immune System - Diseases

Diseases:

Rheumatoid arthritis: Is a disease that mistakenly attacks the joints, causing inflammation. If the inflammation is not controlled, it can damage the cartilage. The joints can become loose. It usually affects the joints of the hands, feet, wrists, knees, elbows and ankles.

Symptoms:
- Joint pain
- Fatigue
- Stiffness
- Swelling in the joints

Vasculitis: When the immune system attacks the blood vessels by mistake. This can happen when there is an infection or disease.
The interruption of blood flow caused by inflammation, can damage the body's organs.

Symptoms:
- Loss of appetite
- Weightloss
- Fatigue
- General discomfort

Myasthenia gravis: Is a chronic neuromucular disease that weakens the skeletal mmusculos the body.
Most people with myasthenia gravis have a normal life esperanzacde.

Symptoms:
- Fatigue
- Difficulty breathing
- Trouble climbing stairs or lifting.
- Dropping eyeli

5.- The Immune System - Process Of The System

Process Of The System:

1. The body recognizes an antigen and delivered to the lymphatic system that is ingested by a macrophage.

2. The macrophage processes and displays the virus antigens.

3. The cell B is activated and produces millions of antibodies which are specific against the antigen.

4. The antibodies are important because the virus can exceed the number of cells of the immune system.

5. Then the antibodies send signals to other immune cells to come and destroy the antibody.

6. The invading cells will be eliminated.

5.- Immune System - Organs And Functions

Organs And Functions:

Skin: It is resistant to bacteria and viruses, the skin also secretes antibacterial substances.

Bone marrow: Is the tissue found inside most bones. All cells such as red cells, white cells, lymphocytes derived from bone marrow.

Thymus: Directs T cells mature. T cells instruct other cells how to react to viruses or foreign cells.

Spleen: It acts primarily as a blood filter, while others can spend sagre bacteris are eliminated.

Lymph node: Is similar to the spleen, it contains the same specialized cells. However, no filters the blood, but filters the lymph (fluid drained composed of tissues).

5.- The Immune System - General System Function

General System Function:

Its main function is to protect against disease and prevent infection. The immune system attacks organisms and substances that invade the body's systems and cause disease.
This consists of a network of cells, tissues and organs that work to protect the body. There are two types of white blood cells:

- Phagocytes: These are cells that destroy invading organisms.

- Lymphocytes: Are cells that allow the body to know that organisms are invaders
