If blood pressure reads 140 systole and 90 diastole, the condition is called

If the blood pressure is measured as 120/80 mm of Hg, the term 120 refers to

The human ciculatory system can be thought of as a closed system of interconnecting pipes through which fluid is continuously circulated by two pumps the two pumps the right and left verticles of the heart, work as simple two-stroke force pumps. The muscles of the heart regulate the force by contracting and relaxing. the contraction (systole) lasts about 0.2s and a complete systole/diastole (contraction/relaxation) cycle lasts about 0.8s. For flood pressures and speeds in the normal range. the volume flow rate of blood through a blood vessel is directly proportional tot he pressure difference over a length of the vessel and to the fourth power of the radius of the vessel. The total mechanical energy per unit volume of blood just as it leaves the heart is E//V=rhogh+P+rhov^(2) Q. Why is diastolic blood pressure muchh lower than systolic pressure? A. because the heart exerts more force on the blood during diastole B. Because the heart exerts no force on the blood during diastole C. Because the radii of the blood vessels increase during diastole while the force exerted by the heart on the blood remains the same. D. Because the radii of the blood vessels increase during diastole while the force exerted by the heart on the blood remains the same.

The upper blood pressure of a patient is 160 cm of Hg whereas the normal blood pressure should be 120 cm of Hg. Calculate the extra pressure generated by the heart in S.I. unit . Take density of Hg=13600 kg m^(-3) and g=9.8 ms^(-2) .

High blood pressure can potentially harm the vital organs like A - Heart B - Brain C - Kidneys D - Lungs

The appearance of albumin in the urine is most likely due to : (a) Increase in the blood pressure (b) Decrease in the blood osmotic pressure (c) Damage to the Malpighian corpuscles (d) Damage to the proximal convoluted tubules

For the first order reaction A(g) rarr 2B(g) + C(g) , the initial pressure is P_(A) = 90 m Hg , the pressure after 10 minutes is found to be 180 mm Hg . The rate constant of the reaction is

Partial pressure of CO_2 in alveoli, oxygenated blood, deoxygenated blood, tissue respectively (in mm Hg) are

At 80^@C , the vapour pressure of pure liquid A is 520 mm Hg and that of pure liquid B is 1000 mm Hg . If a mixture of solution A and B boils at 80@C and 1 atm pressure, the amount of A in the mixture is (1 atm =760 mm Hg) a. 50 mol % , b. 52 mol % ,c. 34 mol% ,d. 48 mol %

Consider the adjacent diagram. Initially, flask A contained oxygen gas at 27^(@)C and 950 mm of Hg , and flask B contained neon gas at 27^(@)C and 900 mm . Finally, two flask were joined by means of a narrow tube of negligible volume equipped with a stopcock and gases were allowed to mixup freely. The final pressure in the combined system was found to be 910 mm of Hg . If flask B were heated to 127^(@)C , maintaining flask A at constant temperature of 27^(@)C , final pressure (in mm Hg ) in the combined system would have been
