Angina occurs due to which of the following reason?
1 When enough oxygen is reaching to heart muscle.
2 When not, enough oxygen is reaching to heart muscle.
3 The deposition of carbohydrates in artery.
4 The deposition of protein in artery:
Explanation:
(b) Angina is a tightness, pain, or discomfort in the chest that occurs when an area of the heart muscle receives less blood oxygen than usual. Symptoms of angina include tightness and difficulty breathing. It's not usually life threatening, but it's a warning sign that you could be at risk of a heart attack or stroke.

Which one of the following statements is correct regarding blood pressure?
1 $190/110\text{mmHg}$ may harm vital organs like brain and kidney,
2 $130/90\text{mmHg}$ is considered high and requires treatment.
3 $120/80\text{mmHg}$ is considered an ideal blood pressure.
4 $105/50\text{mmHg}$ makes one very active.
Explanation:
(c) Blood pressure is the measure of the force of blood pushing against blood vessel walls. The heart pumps blood into the arteries which carry the blood throughout the body. It is usually expressed in terms of the systolic (maximum) pressure over diastolic (minimum) pressure and is measured in millimetres of mercury $\left( \text{mmHg} \right)$.
The ranges of blood pressure are:
Normal: Less than 120 over $80\left( 120/80 \right)$
Prehypertension: $120-139$ over $80-89$
Stage 1 high blood pressure: $140-159$ over 90-99
Stage 2 high blood pressure: 160 and above over 100 and above
High blood pressure in people over age 60: 150 and above over 90 and above.
(b) In normal person, the normal blood pressure is $120/80\text{ }\!\!~\!\!\text{ mmHg}$. The normal systolic (pumping) pressure is $120\text{ }\!\!~\!\!\text{ mmHg}$ and normal diastolic (resting) pressure is $80\text{ }\!\!~\!\!\text{ mmHg}$.
