Coronary Artery Disease CAD is caused from plaque buildup in the arteries. The plaque builds up in the little passage way in the artery causing the flow of blood to lessen‚ which in turn can cause a heart attack. This plaque can also break off and will cause a blood clot‚ which can stop the flow of blood through the vein. Risk factors such as “smoking‚ diabetes‚ high cholesterol‚ and high blood pressure” (National Heart Lung and Blood Institute‚ page 1) can cause the plaque buildup

Palm vein ID authentication‚ which uses an infrared sensor to capture the user’s vein pattern unique to every individual’s palm for an exquisitely sensitive biometric authentication technique. The palm vein scanner has no deleterious effect on the body‚ nor does it require that the device be touched‚ unlike current fingerprint scanners‚ other limitations of various other technologies are related to measuring external features. On the contrary‚ palm vein recognition seems not to

A bacteria has invaded Brittany’s lower lobe of her right lung and we need to report the invasion and document all we see as to what we see also. The femoral vein runs parallel with the femoral artery through the upper thigh and pelvic region of the body (Yahoo Health‚2013) Being one of the larger veins in the body‚ the femoral vein returns blood into the leg to

This essay will also explore the biopsychosocial reasons for William’s initial non-compliance to compression therapy‚ and discuss various models and how they vary in their purpose. The word biopsychosocial originates from three factors‚ biological‚ psychological‚ and sociological (Shorter 2005). Straub (2002) places these three factors together by suggesting that health and disease should be described

people fear the needle as much as the dentist’s office. The act can be even more excruciating when the phlebotomist ruptures the vein and has to stick the patient multiple times.

Polymers have different structures. They also have different functions. Describe how the structures of different polymers relate to their function? Polymers a large molecules made up of a chain of smaller molecules‚ known as monomers. The monomers that a polymer is made up of decide its structure and therefore it’s function. These monomers are linked and coiled in a very specific manor giving the polymer a specific tertiary structure (an extensively coiled and linked polymer chain caused as a

carbon dioxide from the tissues back to the lungs. In order to function most efficiently‚ haemoglobin needs to bind to oxygen tightly when the oxygen concentration is high in the lungs and be able to release oxygen rapidly in the relatively low partial pressure in the tissues. I will be comparing the structure and function of haemoglobin with the structure and function of collagen‚ which is a structural protein. Collagen’s functions are quite different from those of globular proteins such as enzymes;
