Questions Related to blood pressure
Blood enters the heart because of the
-
Auricular diastole
-
Ventricular systole
-
Ventricular diastole
-
Auricular systole
Systole brings about the
-
Entry of blood into lungs
-
Entry of blood into heart
-
Exit of blood from lungs
-
Exit of blood from ventricles
Systole refer to the contraction phase of the
cardiac cycle of the heart between the first and second heart sounds of the cardiac
cycle. Systole causes
the contraction of the ventricles of the heart leading to ejection of blood into the aorta and pulmonary trunk.
Therefore, the correct answer is option D.
Blood pressure in the veins is lower than that of arteries. The best hypothesis to explain this is that
-
Capillaries offer resistance to the blood flow
-
Veins are farther from the heart
-
Most veins carry blood up-hill
-
Veins have thinner walls than arteries
The arteries carry blood away from the heart, while veins return blood to the heart. With both, their structure is related to their function. Blood in the arteries is under high pressure generated by the heart. The arteries have thick outer walls and thick layers of muscle and elastic fibers. The blood in veins is under lower pressure than the blood in arteries. The veins have thin walls and thin layers of muscle and elastic fibers. Unlike arteries, veins have one-way valves in them to keep the blood moving in the correct direction.
Blood pressure in the pulmonary artery is
-
More than that in the carotid
-
More than that in the pulmonary vein
-
Less than that in the vense cavae
-
Same as that in the aorta
Fill in the blanks with suitable words given below:
The instrument used to find out the blood pressure is known as ______
-
Serum
-
Fibrinogen
-
Hemoglobin
-
Pulmonary
-
Sphygmomanometer
-
Ventricles
The instrument used to find out the blood pressure is known as a sphygmomanometer. It is a device composed of an inflatable cuff which displays the pressure measured in mm Hg on the mechanical manometer.
Choose correct alternative in the following statements:
Sphygmomanometer measures
-
Pulse rate
-
Heart beat
-
Blood pressure
-
Brain activity
The sphygmomanometer is a device used to measure blood pressure. It consists of an inflatable cuff, a measuring unit and a mechanism for inflation which may be a manually operated bulb and a valve operated electrically.
Choose the correct answer from the alternatives given.
Drowsiness, felt after a heavy lunch, is due to:
-
increased blood pressure
-
decreased blood pressure
-
decreased pulse rate
-
increased pulse rate
Drowsiness after a heavy lunch is felt due to :
Choose the correct answer from the alternatives given.
Blood pressure is high in and lowest in
-
Arteries; veins
-
Arteries; ventricles
-
Arteries; relaxed atria
-
Arterioles; veins
During systole, because of heart contraction blood is pumped into arteries. Blood pressure is highest as it leaves the heart through the aorta and gradually decreases as it enters smaller and smaller blood vessels (arteries, arterioles, and capillaries). While during atrial diastole, both atria are relaxing, dilating and filling. Blood pressure drops to the lowest level during this state.
Choose the correct answer from the alternatives given.
In an one-circuit circulatory system, blood pressure:
-
cannot be determined
-
is higher at the intestinal capillaries than at the gill capillaries
-
drops significantly after gas exchange has taken place
-
is constant throughout the system
Which of the following trigger renin-angiotens in the system?
-
Increased blood sugar
-
High CI concentration in the blood
-
Lowered blood pressure
-
Increased sodium retention
