Increase in blood pressure is known as

biology human body and organ system blood pressure circulatory system transportation in animal and plants

  1. Hypertension

  2. Hypotension

  3. Hyperglycemia

  4. Hypochromia

Show answer
Correct Option: A
Explanation:

Hypertension is defined as an increase in the blood pressure in the arteries. It is a severe condition which may lead to heart strokes. Normal blood pressure at rest is within the range of 100-140 mm Hg systolic (top reading) and 60-90 mm Hg diastolic (bottom reading). 

So, the correct answer is option A.

The instrument by which blood pressure of a man is determined

biology human body and organ system blood pressure circulatory system transportation in animal and plants

  1. Sphygmomanometer

  2. S.P. meter

  3. Ultrasound

  4. Stethoscope

Show answer
Correct Option: A
Explanation:

A sphygmomanometer is an instrument attached to an inflatable air bladder cuff and used with a stethoscope, for measuring blood pressure in an artery. It is estimated with reference to mmHg.

So, the correct answer is option A.

The instrument used for measuring blood pressure is known as

biology human body and organ system blood pressure circulatory system transportation in animal and plants

  1. ECG.

  2. Stethoscope.

  3. Sphygmomanometer.

  4. EEG.

Show answer
Correct Option: C
Explanation:
The instrument used for measuring blood pressure is known as sphygmomanometer. The blood pressure in the measured in mm of Hg (millimetres of mercury) and recorded with systolic number first followed by diastolic. A normal blood pressure recorded would be 120/80 mm Hg.
So, the correct answer is 'Sphygmomanometer'.

In a normal adult, BP is

biology human body and organ system blood pressure circulatory system transportation in animal and plants

  1. 100/80 mm of Hg

  2. 120/80 mm of Hg

  3. 100/120 mm of Hg

  4. 80/120 mm of Hg

Show answer
Correct Option: B
Explanation:

The instrument used for measuring blood pressure is known as sphygmomanometer. The blood pressure is measured in mm of Hg (millimetres of mercury) and recorded with systolic number first followed by diastolic. In a normal adult, BP is 120/80 mm Hg.

So, the correct answer is '120/80 mm of Hg.

Blood pressure is measured by

biology human body and organ system blood pressure circulatory system transportation in animal and plants

  1. Sphygmomanometer

  2. Phonocardiogram

  3. Electrocardiogram

  4. Stethoscope

Show answer
Correct Option: A
Explanation:
A. Sphygmomanometer is an instrument that measures blood pressure.
B. Phonocardiogram is a record or plot of sounds of heart.
C. Electrocardiogram is a record of electrical activity or the electric current that moves through the heart during a heart beat.
D. Stethoscope is a device by which internal sounds of body are heard.
So, the correct answer is 'Sphygmomanometer'.

The value of diastolic blood pressure is

biology human body and organ system blood pressure circulatory system transportation in animal and plants

  1. 120 mm Hg

  2. 80 mm Hg

  3. 120/80 mm Hg

  4. 40 mm Hg

Show answer
Correct Option: B
Explanation:
There are two components of blood pressure, systolic and diastolic blood pressure.
  • Systolic pressure is the pressure in blood vessels or the force of blood against the wall of arteries when the ventricles pump out blood into them. It is about 120 mm Hg.
  • Diastolic pressure is the pressure or the force of blood against the wall of arteries when the heart is relaxing and getting refilled with blood. It is about 80 mm Hg.
So, the correct answer is '80 mm Hg'.

Blood pressure is controlled by

  1. Thyroid gland

  2. Adrenal gland

  3. Thymus gland

  4. Parathyroid gland.

Show answer
Correct Option: B

Which one indicates hypertension
