The cardiovascular system The heart is a major organ in the body‚ this organ pumps blood around the body‚ through veins‚ capillaries and arteries. The blood carries oxygen to our cells and also carries waste products which include water and carbon dioxide‚ which are products of respiration. Blood also helps spread out salts‚ enzymes‚ urea‚ nutrients‚ hormones and heat across the body. The structure of the heart The heart is located between lungs and it is protected by the rib cage‚ it is thought

journey from the right femoral artery to the lower lobe of the right lung‚ we see many amazing sights. Starting at the femoral vein which is located in the upper right thigh and pelvic region of the body and runs close to the femoral artery. The femoral vein returns blood in the leg to the heart via the iliac vein. As we go north pass through the external and common iliac veins on our way to the small intestines where we can see most of the colon. The common iliac vein is one piece of a large system

(Rachel Mindel) The pancreas is located in the upper abdomen‚ is posterior to the stomach and some parts are in between both the stomach and the spine. The right side of the organ which is called the head‚ is nestled in the curve of the duodenum (juncture where the stomach meets the first part of the small intestine). The tapered left side of the organ is called the body

vessels (arteries‚ veins and smaller vessels) and the blood. The body needs this system to transport oxygen‚ nutrients and waste to the body ’s tissues to maintain homeostasis (active process that maintains a constant internal environment despite external changes). (Tortora 1996) The illustration shows the transport of blood to the body. The arteries and arterioles (Red) and veins and venules (Blue). However‚ there are some exceptions: the Pulmonary veins‚ the Pulmonary arteries and the capillaries

which consists of four arteries to ensure adequate blood flow‚ thyroid bruit with enlargement‚ and “C” cells interspersed with follicular cells. The Superior thyroid artery branches off the common carotid artery and the inferior thyroid artery which branches off the Subclavian artery supply an ample amount of blood to the actual thyroid gland. The thyroid gland has not only a superior vein and a middle vein which both dumps into the internal jugular vein but also an inferior vein that branches into the

blood vessels: arteries‚ veins and capillaries. Arteries carry blood away from the heart while veins carry blood to the heart. Capillaries connect arteries to veins. The right and left halves of the heart act as separate pumps and there is no mix of blood between them. Each half is responsible for pumping blood through one of two blood vessel circuits: the pulmonary circuit and the systemic circuit. In the pulmonary circuit‚ blood leaves the heart through the pulmonary arteries and goes to the
