Answer: 1. How can a healthy lifestyle lead to a healthy heart.

The heart is one of the vital if not the most vital organ of the human body,this is because it is the heart that pumps blood into systemic circulation so that the other body organs,tissues and cells can function adequately.

Any disease or injury to the heart virtually affects all other parts of the body. Therefore a healthy and proper functioning heart is important and this can only be achieved through a healthy lifestyle.

Lifestyles such as;

- Regular exercise/physical activity which will help one to loose excess weight and maintain physical fitness because when one is overweight,fat deposits on the wall of the artery narrowing the lumen/wall, this in-turn causes blood to exert more pressure as it moves through the artery and in-turn lead to hypertension and other heart conditions.

- Stop or limit the intake of alcohol because it increases your chances of getting stroke,heart attack and hypertension through the damage of heart muscles.

- Drinking enough water; this helps the kidney to filter away waste from the body preventing the waste from building up/accumulating in the body especially the heart and as such causing heart problems.

Managing of stress very well to prevent a higher risk of heart disease.

-Eat a healthy diet and manage your blood cholesterol level to prevent damage to heart muscles and blood vessels which will in-turn lead to cardiovascular disease.(High density cholesterol HDL is the good type of cholesterol and low density cholesterol (LDC) is bad for the body.

- Regular visit to a cardiologist when one has a family history of hypertension or any other heart disease.

2. HOW IS HYPERTENSION A BLOOD RELATED DISEASE?

Hypertension is a blood related disease because hypertension is caused when the force of blood along the lumen of artery (artery wall) is higher than normal. This exerted pressure by the blood gets too intense enough to cause a heart problem or a hear disease.

When the pressure gets too intense enough to rupture the artery wall,the individual comes with a heart condition known as stroke.

vichka [17]

Answer:

<h2>potassium</h2>

Explanation:

The heartbeats of the heart are controlled by the sinoatrial node also known as the pacemaker of the heart. The impulse is generated in the conducting cells of the pacemaker as a result of the movement of sodium, potassium and calcium ions.

The sodium channels allow the movement of sodium into the cell which depolarizes the membrane from -60mv to -40 mv. At this point, the calcium gated channels open which allow the entry of the calcium in the cell which depolarizes the cell up to +5mv.

At this point, the potassium channels open which allows the potassium ions to move out of the cell. This repolarizes the cell and hence the cycle again begins.  Reducing the permeability of the potassium ions help generate the autorhythmicity due to repolarization and thus is the correct answer.
