3) When an injury causes a blood vessel wall to break, platelets are activated. They change shape from round to spiny, stick to the broken vessel wall and each other, and begin to plug the break. They also interact with other blood proteins to form fibrin. Fibrin strands form a net that entraps more platelets and blood cells, producing a clot that plugs the break. The reactions that result in the formation of a blood clot are balanced by other reactions that stop the clotting process and dissolve clots after the blood vessel has healed.
Explain how this occurs and how it benefits the patient. Diuretics or “water pills,” help to prevent the body from absorbing too much sodium, which can lead to fluid retention. Diuretics work by assisting the kidneys to eliminate surplus water from the body. This form of treatment benefits the hypertensive patient as fluid retention and a subsequent increase in blood volume, leads to hypertension. By using diuretics, this problem can be managed (Drugs.com, 2013).
These make the bones strong, and when the body needs them, the bones release small amounts into the blood. Another crucial body system is the excretory system. It is the system that collects wastes produced by cells and removes them from the body by excretion. If we didn’t have it, wastes would just pile up and make us sick. Materials that need to be eliminated from the body include excess water, carbon dioxide, and urea, a chemical that comes from the breakdown of proteins.

Reabsorption in the Loop of Henle The loop of henle Differs from the PCT has has considerably less protein channels, because of this the two limbs of the loops have different permeabilities. The descending limb of the loop of Henle is permeable to water so it is here that most of the remaining water with leave the nephrons by osmosis. However due to the lack of protein channels this limb is impermeable to salts and therefore the salts continue through the loop with some of the remaining water. The ascending loop of Henle however is impermeable to water so any water left in the nephron with continue on through into the Distal Convoluted tubule and then to the collecting duct. The ascending limb is permeable though to salts, this allows more salt to diffuse back into the blood and leaves the urea and the remaining water to continue through.
Trypsin is a serine protease found in the digestive system of many vertebrates, where it hydrolyses proteins. Trypsin is produced in the pancreas. I'm thinking as it's an enzyme, it's most likely to be denatured at high temperatures, but if the temperature is at it's optimum then it would speed the rate of reaction, in this case hydrolysis and form a greater amount of product per unit time. * Trypsin is an enzyme which breaks down protein * If Trypsin is added to milk it will break down the milk, turning it from cloudy to translucent protease enzyme that is made in the pancreas and used to digest proteins so that the body can absorb them into the blood. The pancreatic duct in people who have cystic fibrosis frequently becomes blocked, reducing or preventing the release of pancreatic enzyme into the small intestine One enzyme can be used as many times over.
Introduction Caffeine is a stimulant and diuretic. Caffeine binds to cell surface receptors of heart muscle cells, mimicking the effect of epinephrine. Binding of caffeine to these surface receptors blocks the enzyme that degrades intracellular cyclic AMP and thus leads to an increase of cyclic AMP inside the heart muscle cell. Alcohol is produced through anaerobic fermentation by yeast or bacteria. When alcohol is consumed it quickly enters the bloodstream and is distributed to all major organs in the body, such as the heart, brain, liver, pancreas, kidney, etc.
P4: The Cardiovascular system The cardiovascular system refers to the heart, blood vessels and the systematic circulation (blood). Blood contains oxygen and other nutrients which your body needs to survive. The body takes these essential nutrients from the blood. At the same time, the body dumps waste products like carbon dioxide, back into the blood, so they can be removed. The main function of the cardiovascular system is therefore to maintain blood flow to all parts of the body, to allow it to survive.
The lysomal enzymes that normally are bound safely in the vesicles starts the digestion of the membranes of the organelles and the plasma membrane. (Jenkins, G.W. and Tortora, G.J., 2013) D. Two important pieces of information-the instructions Joseph’s body needs to repair itself and his predisposition for vascular disease-are both contained within the
5. Discuss the role of nitrates, beta blockers, and ACE-inhibitors in the patient with an AMI. Nitrates is used to increase collateral blood flow, redistributing blood flow toward the subendocardium; beta blockers is used to reduce heart rate, decrease sympathetic stimulation of the compromised myocardium and prevent life threatening dysrhythmias. ACE inhibitors to prevent ventricular remodeling and the development of heart failure.
