The giraffe has the longest neck of all animals alive today. But the long neck of the giraffe must work with the circulatory system that brings blood to the brain. Since the brain of the giraffe is located so far away from the heart, the blood pressure the heart generates is approximately two times that of another animal with a similar weight. Due to the high blood pressure, the artery walls of the giraffe must be strong otherwise the giraffe would die of internal bleeding. The blood pressure,…

Discovered in 1913 by a man named Nikolai Anichkov, atherosclerosis is a disease where things like calcium and fat build up in the arteries and block blood flow. Arteries harden as a result of it, and it’ll cause problems transferring blood around the body. The plaque will form a barrier, and can cause serious problems in the body, like other diseases and disorders. The results are possibly deadly. There is a layer on the inside of every vein that keeps it smooth called endothelium. It allows…

Purpose: To evaluate the use and efficacy of Stroke Thrombolysis as a treatment in a blocked artery that has caused ischemic stroke. Description of Pathology: Ischemic strokes account for 87% of all stroke incidents, making this type of stroke the most common. Ischemic strokes occur as a result of a blood clot plugging or obstructing an artery carrying blood to the brain. This keeps oxygen and nutrient rich blood from flowing into the brain. If this blockage persists for more than a few minutes…

into four main anatomical areas: head, neck, body, and tail (7). The pancreatic head is the thickest portion of the pancreas and lies within the C-loop of the duodenum, to the right of the superior mesenteric and portal veins. The neck of the pancreas is the narrowest portion of the gland with a width less than 2 cm; lengthwise it traverses the mesenteric blood vessels anteriorly, connecting the pancreatic head and body. The pancreatic body is located between the neck and tail of the pancreas,…

fist. Each cell produces waste products and carbon dioxide. The hearts job is to deliver oxygen and nutrients through arteries, arterioles and capillaries to those cells and remove the produce. Blood is then returned to the heart through venules and veins. Arteries are responsible for moving blood away from the heart. Within most arteries is oxygen, except the pulmonary arteries, they carry deoxygenated blood away from the heart to the lungs. To be able to withstand higher blood pressure,…

result of inadequate oxygen and nutrient supply. Steves condition may have possibly resulted due to adhere to warfarin treatment therefore causing artery blockage (ischemic stroke). This type of stroke results when arteries supplying blood to the brain are blocked or narrowed causing reduced blood flow. This is as a result of thrombus formation in the arteries that supply blood to the brain due to fatty deposit build up. Risk factors. The following are the risk factors that may have led to…

disease”), defined as osteonecrosis of the juvenile hip (Chaundhry, Phillips, Feldman), is a common hip disease affecting school age children. Another name for Perthes disease ischemic necrosis of the hip is a condition that happens when their the femoral head losses blood loss temporary. This disease occurs usually in boys the age of between 4-8 years. The case of this disease is 1 in 1200 children. (Hart,Grottkau e al) . History of perthes disease? In 1909,…

adults, I move on to examine the “ascending aorta, its arch and the arch branches”. The aorta should be cut just distal to the great vessels. Next, I find and open the pulmonary arteries examining them for thromboembolism. After examining the pulmonary arteries, I detach the heart from the lungs by cutting the pulmonary arteries and pulmonary veins close to the pulmonary hila. Next I need to cut the inferior vena cava as it comes through the diaphragm. After this the heart can be removed and…

(The nervous system Louisa Idzal) The nervous system is all connected because it’s a web of nerve cells and fibers that all send nerve impulses throughout and between body parts. The nervous system is really important because it’s in charge of sending messages to the spinal cord and brain to and from all parts of the body. Main organs of the nervous system are Nervous Tissue, Brain, Spinal Cord, Nerves, Sense Organs, and the Cerebrospinal Fluid. The nervous tissue is the main tissue of the…
