Polyp

Patient, a 71-year-old, retired truck driver, presented to Prince of Wales Hospital (POWH) due to an exacerbation of COPD (chronic obstructive pulmonary disease) of 2 days presenting as dyspnea on the background of 5-year history of COPD with 1 or 2 exacerbations a year, previous peripheral venous insufficiency with ulcers, previous solitary pulmonary nodule and an ex-smoker with 100 pack-year history. Initial examination presented with respiratory rate of 22 breaths/minute, oxygen saturation of…

fact that most corals consist of both the coral polyp itself, along with a zooxanthella algae living within it. The two share a mutually beneficial symbiotic relationship in which the coral provides shelter and nutrients to the zooxanthella in return for carbohydrates. However, neither adjust well to fluctuations in temperature, ocean acidification, pollution, or excessive nutrients due to runoff. When there is an increase in temperature, the polyp loses its ability to protect itself from heat…

colonoscopy, the cat will be placed under general anesthesia while a thin tube with an attached camera is inserted into their colon through the rectum. The veterinarian can take tissue samples, remove any polyps and view any abnormalities from within the digestive tract during a colonoscopy. Tissues and polyps removed during the colonoscopy will be sent to an outside lab for further testing. Treatment of Colonic or Rectal Inflammation in Cats Fluid Therapy Because colitis and proctitis can…

A cat’s vestibular system is crucial because it makes the cat aware that he is turning left or right, walking, running, or facing upside down. On the other hand, a cat develops a condition called vestibular disease when the animal is unable to do body coordination, mainly due to several disorders affecting the vestibular apparatus in the inner ear or brainstem. Most of us would have staggered, lost balance, or tilting to one side for a few seconds when you spun around fast, such as when riding…

Cancer is a polyp from benign to malignant involving with cells growing at an uncontrollable rate. Most neoplasms can be either benign or malignant depending on what stage and can be cured if treatments are done in time. Breast neoplasm is an obstruction where polyps are developed, obstructing the normal pathways of one or both nipples, the areola, and the ducts within the vicinity surrounds the breast. There are many forms neoplasms in the breast varying from IDC, which is short for Invasive…

Ivy Tech Community College Columbus Campus Polyps: Polyps are a mass of tissue that arises from the bowel wall and protrude into the lumen. They may develop anywhere in the bowel, but are most common in the sigmoid and colon regions. Polyps are mostly benign, but have the potential to become cancerous. They develop as pedunculated or sessile with pedunculated being more common. The pedunculated become more common with age. Most polyps are less than 1 cm, but can be as large as 4 to 5…

Colon cancer is cancer of the large intestine. It starts off as adenomatous polyps. Adenomatous polyps are little, non cancerous clumps of cell. After a while some of the clumps turn to colon cancer. Doctors are not sure what causes the cancer. Except they do know that it can come when there is an altered cell. When a healthy cell becomes damaged or altered it causes it to divide. Sometimes they divide; even if one is not needed. The cells then invade other cells and tissue. People can also…

underwater ecosystems that are formed by many small animals called polyps, which through their ability to excrete calcium form the limestone skeleton that they live on. As coral reefs grow they can take on three structures fringing, barrier or atoll. The Reef located along the Queensland coastline is called the Great Barrier Reef as it is separated from the shoreline by a section of deep open water. Over many years hard coral polyps form reef structures that support a variety of marine life,…

cnidarians are all stinging creatures, such as jellyfish. SOURCE The polyp stage and medusa stage are different body forms found in the cnidarians jellyfish. The polyp stage is a fixed stage, meaning it does not move from its position. By contrast, the medusa stage is a free roaming stage, meaning it is not fixed and travels around the water. SOURCE Based on the photo, it would appear that the hydra is exhibiting the polyp stage. The part of the hydra that contains the stringing cells…

bright colors that stand out so nicely. Many people consider coral reefs to be very diverse and productive than anything on land. Their skeleton is made out of calcium carbonate protecting them from future encounters with predators. Many more coral polyps then can attach themselves to the coral already there and develops lots of coral reefs grouped together. Photosynthetic algae called zooxanthellae live in the coral’s tissues, protecting them from diseases and providing compounds they need for…
