CIRCULATORY SYSTEM - Coggle Diagram

- - - - The circulatory system consists of three independent systems that work together: the heart, lungs , and arteries, veins, coronary and portal vessels.
        
        Some diseases /disorders
        
        Atherosclerosis. Atherosclerosis is a hardening of the arteriesIt is typically caused by a diet high in fat, which leaves fatty deposits on the lining of the blood vessels.
        
        Heart attack.
        
        Mitral valve prolapse. Mitral valve prolapse means the mitral valve bulges out or prolapses because it does not close evenly.
        
        Mitral valve regurgitation. Mitral valve regurgitation happens when the mitral valve does not close all the way and causes a leak, allowing some of the oxygenated blood to flow backward.
        
        Mitral stenosis. Mitral stenosis means the mitral valve is abnormally narrow which can prevent the blood from flowing smoothly or quickly through it.
        
        Angina pectoris. Angina pectoris means “pain in the chest” and occurs if the heart is not receiving enough blood.
        
        Arrhythmia and dysrhythmia. Arrhythmia and dysrhythmia are often used interchangeably, and both refer to abnormal heart rates and rhythms.
        
        Cardiac Ischemia. Cardiac ischemia means the heart muscle is not getting enough oxygen to function properly.
- - - - Parts: Lymph: Lymph, also called lymphatic fluid, is a collection of the extra fluid that drains from cells and tissues plus other substances. Lymph nodes: Lymph nodes are bean-shaped glands that monitor and cleanse the lymph as it filters through them. Lymphatic vessels: Lymphatic vessels are the network of capillaries and large network of tubes located throughout the body that transport lymph away from tissues. Collecting ducts. Lymphatic vessels empty the lymph into the right lymphatic duct and left lymphatic ductSpleen: This largest lymphatic organ is located on your left side under your ribs and above your stomach. Thymus: This organ is located in the upper chest beneath the breast bone. Tonsils and adenoid: These lymphoid organs trap pathogens from the food you eat and air you breathe.
        
        Some diseases/disorders
        
        Hodgkin's Disease/Hodgkin's Lymphoma Hodgkin lymphoma This is a type of cancer of the lymphatic system.
        
        Non-Hodgkin's Lymphoma. Lymphoma is usually malignant cancer.
        
        Lymphadenitis. Lymphadenitis is an infection of the lymph nodes usually caused by a virus, bacteria or fungi.
        
        Lymphangitis. Lymphangitis is an inflammation of the lymph vessels.
        
        Lymphedema. Lymphedema is the chronic pooling of lymph fluid in the tissue.
        
        Lymphocytosis. Lymphocytosis is a high lymphocyte count.
- - - - Parts: Lymphoid organs; Primary lymphoid organs: These organs include the bone marrow and the thymus. Secondary lymphoid organs: These organs include the lymph nodes, the spleen, the tonsils and certain tissue in various mucous membrane layers in the body. Bone marrow
        Bone marrow is a sponge-like tissue found inside the bones. Thymus The thymus is located behind the breastbone above the heart. Lymph nodes Lymph nodes are small bean-shaped tissues found along the lymphatic vessels. SpleenThe spleen is located in the left upper abdomen, beneath the diaphragm. Tonsils The tonsils are also part of the immune system. Mucous membranes The bowel plays a central role in defending the body.
        
        Some diseases/disorders
        
        Asthma. It is a chronic inflammatory disorder of the airways characterized by coughing, shortness of breath, and chest tightness.
        
        Ataxia telangiectasia. It is a progressive, degenerative disease characterized by cerebellar degeneration, immunodeficiency, radiosensitivity and a predisposition to cancer.
        
        Autoimmune polyglandular syndrome. Autoimmune polyglandular syndrome type I is a rare autosomal recessive disorder that maps to human chromosome 21.
        
        Burkitt lymphoma. Burkitt lymphoma is a rare form of cancer predominantly affecting young children in Central Africa, but the disease has also been reported in other areas.
        
        Diabetes, type 1. Diabetes is a chronic metabolic disorder that adversely affects the body's ability to manufacture and use insulin, a hormone necessary for the conversion of food into energy.
        
        DiGeorge syndrome. DiGeorge syndrome is caused by a large deletion from chromosome 22, produced by an error in recombination at meiosis.
