I never knew the value of life until I held a human heart in my hand. The human body is strong and powerful with bones‚ muscles‚ nerves‚ arteries‚ and veins‚ but so fragile; one thing goes wrong and that is where surgeons come in. Everyone ended up at the CSU Anatomy Camp for two reasons: to learn about the medical field and have experiences. It was like walking into a room full of like-minded people‚ who were eager to learn. I was there because I needed to be with people who could teach me and

Introduction Fibromuscular dysplasia (FMD) is currently defined as an idiopathic‚ segmental‚ non-inflammatory and non-atherosclerotic disease of the musculature of arterial walls‚ leading to stenosis of small and medium-sized arteries.[1] The prevalence of FMD is not precisely known. Several studies determined prevalence in arteriograms of potential kidney donors. Craig et al reviewed the results of 1‚862 renal angiograms obtained in potential renal donors and found FMD in 71 patient (3.8%).[2]

Abstract Pancreatic adenocarcinoma (PDAC) is one of the deadliest cancers worldwide and has a poor five year survival rate. A reason for this poor survival rate is the delay in diagnosis due to the late presentation of symptoms. This paper focuses on the different imaging modalities used to detect and diagnose pancreatic adenocarcinoma. Radiography is a modality utilized when a patient presents with abdominal pain or back pain‚ two common symptoms of PDAC. Ultrasound (US) is the commonly used front

temperature. The liver also stores vitamins until needed. Proteins‚ manufactured in the liver‚ are responsible for normal blood clotting. The liver is also a filter for keeping out harmful substances. It regulates the amount of red blood cells in circulation by breaking down and absorbing the cells. As a filter‚ the liver absorbs harmful chemicals and even some poisons and breaks them down into less harmful materials. The liver then allows the substance to pass out of the body through the urine.

6 primary functions of digestive system: 1. Ingestion- food intake 2. Secretion 3. Digestion- mechanical & chemical breakdown of food Mechanical Mastication- first step. Enables mixing with saliva to form bolus to be swallowed. Regulated by CNS. Deglutition Mixing/Churning Peristalsis- movement of muscles within GI tract that facilitates movement of food Chemical- Hydrolysis (using H2O) of macromolecules into monomers (residues) carried out by digestive enzymes produced by salivary glands

Lymphoid tissues contain lymphocytes‚ but they also contain other types of cells for support.[3] The system also includes all the structures dedicated to the circulation and production of lymphocytes (the primary cellular component of lymph)‚ which includes the spleen‚ thymus‚ bone marrow‚ and the lymphoid tissue associated with the digestive system.[4] The blood does not directly come in contact with the parenchymal

Communication‚ Homeostasis & Energy Communication & Homeostasis Outline the need for communication systems within multicellular organisms‚ with reference to the need to respond to changes in the internal and external environment and to co-ordinate the activities of different organs. Organisms need to respond to external stimuli‚ e.g. temperature‚ oxygen concentration and levels of sunlight. These may be over time‚ e.g. winter fur to summer fur‚ or quickly‚ e.g. changing size of pupils. Internal

The CNS should be able to calculate a MELD score to ensure that referral to a transplant center is not delayed‚ as early treatment with abstinence has been shown to improve the outcome and histological features of hepatic injury‚ to reduce portal pressure and decrease progression to cirrhosis‚ and to improve survival at all stages in patients with ALD.
