  1. Explain Poiseuille’s Law and Ohm’s Law

In simple terms, Poiseuille’s law explains the dynamics that are at play when a fluid such as blood or lymph flows inside the vessel in which it moves. The blood is to the vascular system what lymph is to the lymphatic system of tubes. The fluid pressure in these enclosed tubular systems has a special mathematical relationship to the velocity, viscosity, and length of the tube or vessel in which it flows. Considering the law of Physics as applied to a biological system such as the human body, the velocity or speed of blood and lymph in their tubular systems will be directly proportional to the pressure of the blood and lymph in the vessel. Also, that velocity of the blood or lymph will be directly proportional to the fourth power of the radius (r4) of the vessel. What this means is that the higher the speed of flow the higher the pressure and the value of r4. However, the velocity of the blood or lymph will be inversely proportional to the viscosity or thickness of the blood or lymph as well as the length of the vessel. This means the thicker the blood (for instance), the slower it will flow through the vessels. Also, the longer the vessel, the slower the flow of blood will be (Zhang et al., 2016)Case Study For Hyperlipidemia Essay Paper.

Ohm’s law is another law in Physics related to electricity that is a mirror image of Poiseuille’s law; only that it describes the relationship that current has with pressure (voltage) and resistance. In that case, what it means is that the stronger the current or electrical impulse, the higher the voltage or potential difference. Also, the higher the resistance, the weaker the current and the two are thus inversely proportional (BYJU’S, 2022)Case Study For Hyperlipidemia Essay Paper.

  1. Is there an inverse relationship between HDL and atherosclerosis? Explain

Indeed an inverse relationship exists between high-density lipoprotein cholesterol or HDL cholesterol and atherosclerosis. Atherosclerosis is the deposition of fatty plaques in the interior lumen of arteries causing gradual occlusion of those arteries (Hammer & McPhee, 218; Huether & McCance, 2017)Case Study For Hyperlipidemia Essay Paper. It is responsible for angina pectoris, ischemic stroke, and myocardial infarction. HDL cholesterol is described as “good” cholesterol because the higher its value is in the blood the less the deposition of fatty plaques hence atherosclerosis. It is the opposite of low-density lipoprotein (LDL) cholesterol which is the one that encourages atherosclerosis and hence should be low in the blood.
