Levels of total cholesterol and ldl cholesterol are directly related to the frequency of coronary heart disease. a) true b) false

a) true

Explanation:

Blood conducts cholesterol from the intestine or liver to the organs that need it and does so by binding to particles called lipoproteins. There are two types of lipoproteins:

Low density (LDL): they are responsible for transporting new cholesterol from the liver to all the cells of our body.

High density (HDL): collect unused cholesterol and return it to the liver for storage or excretion abroad through bile.

According to this interaction we can talk about two types of cholesterol:

Bad cholesterol: Cholesterol when attached to the LDL particle is deposited in the wall of the arteries and forms atheroma plaques.

Good cholesterol: Cholesterol when attached to the HDL particle transports excess cholesterol back to the liver for destruction.

- If their blood levels rise they produce hypercholesterolemia. It is shown that people with blood cholesterol levels of 240 have twice the risk of having a myocardial infarction than those with figures of 200.

- When the cells are unable to absorb all the cholesterol that circulates in the blood, the excess is deposited in the wall of the artery and contributes to its progressive narrowing causing atherosclerosis.

- If an atheromatosis patient keeps his blood cholesterol levels very low, he can get that cholesterol from the arterial wall back to the blood and be eliminated there. Therefore, patients who have suffered myocardial infarction or brain accident are recommended to maintain very low cholesterol levels to try to clean their arteries.

Hypercholesterolemia has no symptoms or physical signs, so its diagnosis can only be made by a blood test that determines cholesterol levels and also triglycerides. It is convenient that people at risk of having a dyslipidemia (alteration of the normal levels of these fats), who have relatives with ischemic heart disease and other cardiovascular diseases, undergo this test from an early age.

answer: c

explanation:

mientras se trata la anorexia o la bulimia, es importante buscar ayuda antes que nada. un profesional de la salud mental será el más útil para aquellos que sufren anorexia o bulimia. este es un buen lugar para comenzar, sin embargo, ver a otros profesionales como dietistas registrados, especialistas médicos y dentistas podría ayudar a alguien a recuperarse de un trastorno alimentario. después de la ayuda profesional, o si la ayuda profesional no es una opción, alguien que se recupere de la anorexia o la bulimia debe rodearse de compañeros de apoyo, padres u otros miembros de la familia que también estén comprometidos con el proceso de recuperación.

hope this you! : )
