Questions Related to blood pressure

In adult, man normal BP is 

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

  1. 100/80 mm Hg

  2. 120/80 mm Hg

  3. 100/120 mm Hg

  4. 80/120 mm Hg

Show answer
Correct Option: B
Explanation:

Blood pressure is the pressure of the circulating blood against the walls of the arteries, the veins, and the chambers of the heart. The blood pressure in the large artery of the heart, the aorta, and the other large arteries of a healthy adult is usually 120 mm Hg during the contraction of the heart (systole), and 80 mm Hg during relaxation of the heart (diastole). Normal blood pressure is less than 120/80 mm Hg. So, the correct answer is-120/80 mm Hg.

The instrument by which blood pressure of a man can be determined is

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

  1. Ultrasound

  2. Blood pressure meter

  3. Stethoscope

  4. Sphygmomanometer

Show answer
Correct Option: D
Explanation:
A sphygmomanometer is an instrument, often attached to an inflatable air bladder cuff and used with a stethoscope, for measuring blood pressure in an artery.
So, the correct answer is option D.

Choose the correct statement: If the vasopressin receptor of a man is defective. Then

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

  1. He suffer from low blood pressure and dehydration.

  2. Shows hyperglycemic condition. c)

  3. Excessive thirst does not occurs

  4. The urea level in the urine is higher than the normal.

Show answer
Correct Option: A
Explanation:

  • Vasopressin regulates the tonicity of body fluids. It is released from the posterior pituitary in response to hypertonicity and causes the kidneys to reabsorb solute-free water and return it to the circulation from the tubules of the nephron, thus returning the tonicity of the body fluids toward normal.
  • If vasopressin receptors are absent, it would result in increased loss of water from the body, leading to dehydration, increased thirst and Increased blood pressure.
So, the correct option is 'He suffers from low blood pressure and dehydration'.

Select the statement which correctly describes the particle pressure of gases in inhaled and exhaled air:

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

  1. The $pO _2$ in alveolar air is lower than $pO _2$ in venous blood

  2. The $pCO _2$ in exhaled air is greater than $pO _2$ in alveolar air

  3. The $pO _2$ in exhaled air is greater than $pCO _2$ in alveolar air

  4. The $pO _2$ in arterial blood s grater than $pO _2$ in alveolar air

Show answer
Correct Option: A

Persons suffering from high blood pressure should take which of the following precautions to avoid excessive rise in their blood pressure?

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

  1. Sleep as much as possible

  2. Avoid standing

  3. Increase their weight

  4. Avoid emotional disturbances and excitement

Show answer
Correct Option: D
Explanation:

High blood pressure can cause serious medical problems. Reacting to stress in high blood pressure can increase the risk of heart attacks and strokes due to the increase of blood flow in blood vessels. So, to avoid stress is one of the precautions for the persons having high blood pressure.

 Hence the correct answer is option D.
