Questions Related to blood pressure
Blood pressure is defined as the force with which blood
-
Comes out of the atrium
-
Is pushed to the legs
-
Pushes against wall of blood vessels
-
Comes out of the ventricle
The force with which the blood pushes against the walls of the blood vessels, usually arteries, is known as the blood pressure. It is described in the unit mm Hg. The normal diastolic and systolic pressure of the adult human heart is 120 mm Hg and 80 mm Hg, respectively.
Thus, the correct answer is 'Pushes against wall of blood vessels.'
Which of the following statements is incorrect ?
-
Mammals have the ability to produce concentrated urine.
-
Counter current is due to the flow of filtrate in two limbs of Henle's Loop in opposite direction.
-
Henle's loop and vasa recta play a significant role in concentrating the urine.
-
Flow of fitrate through vasa recta also follow the counter current pattern.
Flow of blood through vasa recta follows counter current pattern. Filtrate flows through loop of Henle.
The reabsorption of the sodium from glomerular filtrate is regulated by the hormone _____________.
-
Glucagon
-
Secretin
-
Aldosterone
-
Adrenaline
Aldosterone is secreted by the outer layer of the adrenal gland. When aldosterone is present in the blood, all the $Na^{+}$ in the filtrate is reabsorbed b the epithelial cells of DCT and collecting duct. Retaining $Na{+}$ raises the osmotic pressure of the blood and reduces water loss from the body.
State the following statement true or false:
Contraction phase of the heart is the diastole.
-
True
-
False
A) The contraction phase of the heart is called systole.
Normal systolic and diastolic value of blood pressure is
-
80/120 mm Hg
-
80/40 mm Hg
-
140/80 mm Hg
-
120/80 mm Hg
A) Blood pressure is always read as systolic/diastolic pressure. Systolic pressure is 120 mm Hg while diastolic pressure is 80 mm Hg.
D) 120 mm Hg here, represents the systolic pressure and 80 mm Hg represents the diastolic pressure.
Excess of Na++ ions in human system causes____________________
-
Diabetes
-
Anemia
-
Low blood pressure
-
High blood pressure
- The increasing of the concentration of Sodium ions in blood would attract water from the surrounding issues, because of the osmotic pressure.
Which of the following figure illustrates the systolic and diastolic pressure?
-
120 mm Hg
-
80 mm Hg
-
120 mm Hg and 80 mm Hg respectively
-
80 mm Hg and 120 mm Hg respectively
The diastole phase is the phase of relaxation where the chambers of the heart relax and blood fills into the respective chambers. The systolic phase is the phase of contraction. The normal systolic pressure is about 120 mm Hg & diastole pressure is 80 mm Hg.
Cardiac systole is the .......... cardiac muscle in response to an electrochemical stimulus to the heart's cell.
-
Relaxation
-
Contraction
-
Both A and B
-
None of the above
The diastole phase is the phase of relaxation where the chambers of the heart relax and blood fills into the respective chambers. The systolic phase is the phase of contraction. The normal systolic pressure is about 120 mm Hg & diastole pressure is 80 mm Hg. So, the correct answer is option B.
Which one of the following statements is correct regarding blood pressure?
-
$130/90 $ mm Hg is considered as high and requires treatment.
-
$100/55 $ mm Hg is considered ideal blood pressure.
-
$105/50 $ mm Hg makes one very active.
-
$190/110 $ mm Hg may harm vital organs like brain and kidney.
Systolic pressure in a normal human is
-
$70$ mm of Hg
-
$80$ mm of Hg
-
$90$ mm of Hg
-
$120$ mm of Hg
Blood pressure is measured in 2 categories, systolic blood pressure and diastolic blood pressure. The systolic pressure is the amount of pressure in the arteries during the contraction of the heart muscle. The diastolic pressure is the pressure during the resting period between heartbeats. The normal value of systolic pressure in human is 120 mm of Hg. The normal value of diastolic pressure in human is 80 mm of Hg.
