Vein

The three basic types of blood vessels, including capillaries, arteries and veins. • Arteries take oxygen-rich blood away from heart. • Veins take blood back toward heart. • Capillaries are very tiny blood vessels that form a connection between arteries and veins. Transfer of nutrients, oxygen and wastes in and out of body facilitated by the capillary. 3. The Blood The heart pumps blood throughout body. The blood is…

pulmonary edema are shortness of breath, difficulty breathing, and chest pain. Edema in the legs can happen from long periods of time sitting such as a long flight. Persistent leg pain and swelling could be signs of a potential blood clot in the veins called deep vein thrombosis, or DVT for short. Edema could also be the result of eating too much salty food, premenstrual…

or reduce the coagulation of blood, prolonging the clotting time. Given a drug like Heparin acutely can limit the further formation of thrombus. When given chronically, for example Warfarin help prevent thromboembolism from the venous system (Leg veins). These drugs can also prevent clot formation in a dissected area. Thrombolytic drugs dissolve blood clots by activating plasminogen, which forms a cleaved product called plasmin. Plasmin is a proteolytic enzyme that is capable of breaking…

the capillaries. It’s in the capillaries where the diffusion process takes place to exchange molecules of oxygen and nutrients for carbon dioxide of nearby cells, after leaving the capillaries blood is collected into venules the smallest of veins then into veins of increasing size until it reaches the heart [6]. The right side of the heart receives blood returning from the tissues and pumps it towards the lungs,…

is largely contributed to the feeble veins that elderly have. Vein quality can be contributed to many different patient characteristics as well. In many hospitals, the patients who have an IV inserted in their arm or hand are only getting their IV site assessed and flushed once per shift. There was no correlation in Salgueiro-Oliveira & Parreira’s study of the duration of the indwelling IV catheter and solely inflammation of the vein due to medications and vein integrity, although the chance of…

constant (Merriam-Webster). Optic nerve: A part of the central nervous system, the optic nerve connects the eye to the brain, carrying electrical signals formed by the retina to be interpreted as images (Medicine Net). Central retinal vein: The central retinal vein is where blood circulating in the eye is returned to the heart to be cleaned. It forms the arterioles, branches of an…

5. What are the potential contraindications that can prevent someone from having a cardiac catheterization? What is the contraindication that must be considered in Robert Wilson’s case? Why is this of concern? There are potential contraindications to getting a cardiac catheterization, though the only contraindication is the inability to provide an informed consent. There have been unstable patients how have tolerated this procedure but with high risk patients, the nurse has be cautious of…

Describe the structure and function of the cardiovascular system Blood vessels Arteries, veins and capillaries takes blood and nutrition to the muscles and back from the heart. Arteries take the blood that has O2 in it away from the heart under high pressure with a small diameter and it has thick muscular walls, and veins take the blood back to the heart under low pressure it has a medium thickness to it and a large diameter because it has valves to stop the blood flowing backwards.…

The roaring of the loud crowd surrounds me like an ambush of tigers sucking out my inner anxiousness to paint an impeccable picture of itself on my face. I feel the adrenaline rushing in my blood and crawling creepily at the speed of light to the blood vessels in my face. My temperature rises as if my cheeks were slowly absorbing the heat from a hot stove. I support the weight of high expectations on my shoulder from myself and my family. I get onto my starting block and after every second…

When varicose veins are very close to the surface of the sin, they may spontaneously rupture and bleed. A minor injury to the skin can also make them bleed, usually in the veins near the ankle. These may not cause any weakness or pain. When pressure builds up in varicose veins near the ankle or foot, the pressure may be as strong as arterial blood pressure. This is because of gravity along with the pressure of blood that pools in the veins. The vein may rupture and bleed into the surrounding…
