Question

In a normal adult, BP is
(a)100/80 mm of Hg
(b)120/80 mm of Hg
(c)100/120 mm of Hg
(d)80/120 mm of Hg

Answer 1

Hint: Blood pressure (BP) is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. Blood pressure is usually expressed in terms of the systolic pressure over diastolic pressure in the cardiac cycle. It is measured in millimeters of mercury (mmHg).

Complete answer:
Normal blood pressure is below 120/80 mm Hg When used without qualification, the term “blood pressure” refers to the pressure in the large arteries. AS we said earlier it is measured in millimeters of mercury (mmHg) above the surrounding atmosphere. If you're an adult and your systolic pressure is 120 to 129, and your diastolic pressure is less than 80, you have elevated blood pressure. ideal blood pressure is considered to be between 90/60mmHg and 120/80mmHg. High blood pressure is considered to be 140/90mmHg or higher. Low blood pressure is considered to be 90/60mmHg or lower. In hypertension, systolic pressure is above 140mm Hg and the diastolic pressure is above 90mmHg.

Additional Information: -Certain cardiovascular problems occur in man in relation to the variation of blood pressure. These include hypotension and hypertension.
-The low blood pressure is known as hypotension. Under such condition blood pressure falls to below 100mm Hg during systole and to below 60 mm Hg during diastole.
-Hypertension is a case of sustained high blood pressure. The blood pressure will be above 140mm Hg during systolic and above 90 mm Hg during diastole.
So, The correct option is ‘B’.

Note: -Blood is the chief transporting medium in the human body. Blood constitutes almost 8% of total body weight.
-In a normal male, there will be 5-6 liters of blood, and in a healthy female 4-5 liters of blood.
-Human blood is a thick, red-colored, and slightly alkaline viscous fluid. It consists of blood plasma and blood corpuscles.
