These fragile and exposed blood vessels rupture and leak very easily causing retinal scaring which in turn pulls the retina out of position. These scars usually shrink as they heal and dry causing immense pressure at the retinal conjunction eventually enough pressure tears the lining, completely…

Without blood, we could not live. This is because it keeps us warm, fights off infections, and helps get rid of waste(Durani). Blood also transports oxygen and hormones throughout our body. Our circulatory system is made up of the heart and blood vessels. They also include arteries, veins, and capillaries. There are two parts to the circulatory system: the pulmonary circulation and the systemic circulation. The pulmonary circulation is a short loop from the heart to the lungs and then repeats.…

The arteries are blood vessels that deliver oxygen and nutrients to all organs in the body during the heart pulses. During the blood circulation a pressure is exerted on the walls of the blood vessels or arteries. The case where the ability of such walls to expand or contract in response to blood pressure changes is called Arterial Stiffness (AS). Arteries need to be flexible to expand when oxygen is needed by muscles and heart, and stiffening of the arteries place an extra load on heart which…

The cardiovascular system The cardiovascular system consists of the heart, blood vessels and approximately the 5 litres of the blood that the blood vessels transport. The cardiovascular system is powered by the body’s hardest working organ. The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from your body. The main structures of this system is the heart the blood vessels and blood. Delivery of oxygen and nutrients The pulmonary circuit carries blood…

The left side of the heart then pumps blood into the circulatory system of blood vessels that carry blood throughout the body. Heart failure is an illness in which the pumping action of the heart becomes less and less powerful. When this happens, blood does not move efficiently through the circulatory system and starts to backup, increasing the pressure in the blood vessels and forcing fluid from the blood vessels into body tissues. Symptoms depend on which area of the body is most involved in…

Pseudoaneurysm A pseudoaneurysm occurs when there is injury to an artery. The injury allows blood to leak out of the artery. The leaking blood collects or pools and is contained in the nearby tissues. CAUSES The most common cause of this condition is a procedure that involves inserting a thin tube (catheter) into an artery, such as an angiogram. After an angiogram, if the insertion site does not fully seal, blood may leak out of the artery. Other causes include: • Trauma to the walls of an…

Early signs include general fatigue and swelling of hands and feet which occur as a result of blood vessel occlusion common in the joints of the body due to decreased oxygen levels causing the RBCs to have the sickle shape which inflicts pain and weakness on the individual. The SCD patient will exhibit psychosocial and behavioral changes such as agitation…

the azygos vein, which carries deoxygenated blood from the rib cage, to form the superior vena cava. The blood that flows into the heart from the superior vena cava is controlled by the contractions of the heart. The basilic vein is a large blood vessel within the arm. Between the shoulder and the elbow, this vein courses underneath muscle tissue.…

This is a recommendation for investment in Project Andiamo, a London based company that creates custom orthotics that helps kids with disabilities. The company aims at helping these kids with life changing improvement to posture & mobility using the emerging 3D printing technology. What make this 3D printed orthotics different from the traditional braces are, its accuracy and the time it takes to make a brace. The drawbacks however are: 1) The technical challenges associated with a introducing…

Treatment for a stroke relies on upon whether it is ischemic or hemorrhagic. Treatment for a transient ischemic assault (TIA) relies on upon its cause, how much time has gone since indications started, and whether you have other therapeutic conditions. Strokes and TIAs are therapeutic crises. In the event that you have stroke side effects, summon 9–1–1 right. Try not to drive to the doctor's facility or let another person drive you. Call a rescue vehicle so that restorative faculty can start…
