The 11 organ systems include the integumentary system, skeletal system, muscular system, lymphatic system, respiratory system, digestive system, nervous system, endocrine system, cardiovascular system, urinary system, and reproductive systems. The VA defines 14 disability systems , which are similar to the body systems. However, the disability systems are separated differently for rating purposes.
These systems are listed with the medical listing and are identified independently when necessary. For Individual Unemployability ratings; if you are rated with more than one disability within one body system, your rating will increase towards unemployability. For this reason, we have outlined the VA defined body systems and have included a link to our VA Unemployability Calculator so you can see if your ratings make you eligible for Individual Unemployment.
Below is a description of the basic functions of each system as well as some of the diseases and disorders associated with each system. These lists are not complete and do not take the place of medical advice.
It acts as a barrier to physical, chemical, and biological agents. The skin prevents water loss and regulates body temperature. It transmits the senses of touch, pain, and pleasure and maintains body temperature by secreting sweat. The hair lubricates the scalp, which secretes pheromones and cools or warms our heads.
The nails protect our fingers, which are a major tool used for protecting ourselves and providing ourselves with food, shelter, and sensations. The skin leaves us most vulnerable when it is compromised by open wounds, allowing infectious agents into the body.
The ribs protect the abdominal organs, which are both vulnerable to injury and dangerous to our well being when injured. The skull protects our brain which controls all functions of our bodies and minds. The skeleton provides the framework and shape to our bodies. It also connects to our major muscles to allow movement. Bones store minerals such as calcium and create blood cells in the soft bone tissue called marrow. Bones can break easily without enough calcium and are subject to such diseases as arthritis; cancers; scoliosis; osteoporosis, gout; bursitis; fractures and breaks; and amputations.
This system transports clean fluids in our body back to the blood and drains excess fluids and debris from the tissues and cells of the body. It also houses the white blood cells lymphocytes involved in protecting our bodies from infection. This system maintains our breathing.
It supplies the body with oxygen for cellular respiration by collecting oxygen in the lungs and disposes of carbon dioxide by breathing out the waste product. It also provides our functions of speech and smell.
Diseases and disorders of the respiratory system include allergies; rhinitis and sinusitis; laryngitis; COPD; pleurisy; bronchitis; emphysema; asthma; sarcoidosis; fibrosis; asbestosis; pulmonary vascular diseases; fungal or bacterial infections of the lungs; sleep apnea; tuberculosis of the respiratory system; and lung, throat, and other respiratory cancers. Beginning with our mouths, this system is responsible for the breaking down and absorption of nutrients and the elimination of the waste not utilized by the body.
Different organs can work together to perform a common function, like how the parts of your digestive system break down food. We refer to an integrated unit as an organ system. Groups of organ systems work together to make complete, functional organisms, like us! There are 11 major organ systems in the human body. The circulatory system is a body-wide network of blood, blood vessels, and lymph.

The respiratory system , which includes air passages, pulmonary vessels, the lungs, and breathing muscles, provides oxygenated blood to the body tissues and removes waste gases. The digestive system enables your body to convert food into usable nutrients through a chemical breakdown process. This occurs through a system of tube-like of organs, including the esophagus, stomach, liver, pancreas, and intestines.
The skeletal system gives the body its basic framework, providing structure, protection, and movement. Explanation: This includes the circulatory, respiratory, digestive, excretory, nervous, and endocrine systems. Related questions What the chemical messengers that travel in the blood?

Prostatitis — Prostatitis is swelling of the prostate gland, often caused by advanced age.
Kidney Stones — These are stones found in the urinary tract. Body System Integumentary System The integumentary system is an organ system that protects the body from damage, loss of water, or abrasion from outside. Warts — Warts are bumps caused by a viral infection most commonly on the hands and feet. Eczema — This is a condition that presents as red, itchy, flaky skin.
Vitiligo — With this condition, there is a loss of skin color that appears in blotches. Psoriasis — This inflammatory skin condition presents as red, itchy plaques that occur most commonly on the knees and elbows. Melanocytic Nevus — This is a usually noncancerous disorder of pigment-producing skin cells commonly called a birth mark or mole.
Basal Cell Carcinoma — With this type of cancer, the skin has a slight pearl color which rarely spreads to other parts of the body but must be treated.
Squamous Cell Carcinoma — This skin cancer shows as a rough-surfaced skin-colored lesion, which causes death in about 10 percent of affected patients.
Melanoma — Melanoma is a skin cancer presenting as a dark, changing, bleeding skin spot which can be fatal in 35 percent of patients diagnosed. Body System Reproductive System The reproductive system is a combination of bodily organs and tissues used in the process of producing offspring.
Diseases and Disorders of the Reproductive System Cervical Cancer — Cervical cancer results in a malignant tumor of the cervix. Vaginal Yeast Infection — This is an infection caused by a yeast fungus in the vagina. Endometriosis — Endometriosis is a condition where tissue that normally lines the uterus ends up outside the uterus.
Gonorrhea — Gonorrhea is a sexually transmitted bacterial infection that may cause infertility if left untreated. Body System Digestive System The digestive system breaks down food, extracts nutrients into the bloodstream, and excretes waste.
