The five vital organs in the human body are the brain, the heart, the lungs, the kidneys, and the liver. Other organs include the gallbladder, the pancreas, and the stomach. Organ systems, such as the nervous system, support these organs. Keep reading to learn more about the organs of the body, the various organ systems, and some guidelines on how to maintain optimum health. The vital organs are those that a person needs to survive. A problem with any of these organs can quickly become life threatening. It is not possible to live without these organs. That said, in the case of the paired kidneys and lungs, a person can live without one of the pair. The sections below will look at the five vital organs in more detail. Brain The brain is the body’s control center. It forms the core of the central nervous system by creating, sending, and processing nerve impulses, thoughts, emotions, physical sensations, and more. The skull encloses the brain, protecting it from injury. Neurologists are doctors who study the nervous system. Over time, they have identified numerous parts of the brain, including systems within the brain that function similarly to independent organs. The brain is made up of three main subparts: the cerebrum, the The major areas of the central nervous system • The medulla: This is the lowest part of the brainstem. It helps control heart and lung function. • The pons: Located above the medulla in the brainstem, this area helps control eye and facial movement. • Th...

Normally, the appendix sits in the lower right abdomen. The function of the appendix is unknown. One theory is that the appendix acts as a storehouse for good bacteria, “rebooting” the digestive system after diarrheal illnesses. Other experts believe the appendix is just a useless remnant from our evolutionary past. Surgical removal of the appendix causes no observable health problems. Appendix Conditions • Appendicitis: For unclear reasons, the appendix often becomes inflamed, infected, and can rupture. This causes severe pain in the right lower part of the belly, along with nausea and vomiting. • Tumors of the appendix: Carcinoid tumors secrete chemicals that cause periodic flushing, wheezing, and diarrhea. Epithelial tumors are growths in the appendix that can be benign or cancerous. Appendix tumors are rare. Appendix Tests • • CT scan (computed tomography): A CT scanner uses X-rays and a computer to create detailed images. In appendicitis, CT scans can show the inflamed appendix, and whether it has ruptured. • • Complete blood count (CBC): An increased number of white blood cells -- a sign of infection and inflammation -- are often seen on blood tests during appendicitis. • Other imaging tests: When a rare tumor of the appendix is suspected, imaging exams may locate it.

Normal chest x ray Radiological anatomy is where your X-ray), computed tomography ( CT) and magnetic resonance imaging ( MRI). X-ray and CT require the use of ionizing radiation while MRI uses a magnetic field to detect body protons. MRI is the safest among the three, although each technique has its benefits. The preferred method depends on the structures we wish to examine.  Scan interpretation will be a lot easier for you if you have analyzed Key facts X-ray radiography An imaging technique which uses beams of electromagnetic waves (x-rays) to produce radiographs that depict the tissues in two dimensions based on their density. Commonly used for assessment of chest, abdominal and skeletal anatomy. Computed tomography (CT) An imaging technique which uses X-ray beams to produce images that depict the tissues in two and three dimensions based on their density. Commonly used for assessment of musculoskeletal system, parenchyma of solid organs, distribution of body fluids. Magnetic resonance imaging (MRI) An imaging technique which uses radio-waves and magnetic fields to produce images based on the tissue’s proton (hydrogen) levels. Commonly used for examination of soft and nervous tissues. Ultrasonography (U/S) An imaging method which uses high frequency sound waves to depict tissues based on their density. Wide array of indications (e.g. Doppler U/S, breast U/S, obstetric U/S) Nuclear medicine Spectrum of imaging methods used for examining the function of specific body p...
