Blood pressure overall measures the elasticity of the arteries near the heart as they stretch to accommodate expelled blood.
Blood pressure within the arterial system takes into account that pressure is different at varying locations.
Blood pressure is simply the force that the blood exerts in all directions within any given area, measured as a ratio.
Blood pressure represents the pulse difference between ventricular contractions.
The ventricular contraction asserts capillary pressure that is about 70 mm Hg.
The pressures at different places in the circulatory system are different.
Increase in blood pressure can occur if arterial walls lose some of their elasticity.
Blood pressure is expressed as a ratio of systolic over diastolic pressure.

Blood pressure can be treated only by monitoring baroreceptors.
Blood pressure can be treated only by monitoring chemoreceptors.
Blood pressure can be treated only by monitoring the kidneys.
Blood pressure can be regulated through baroreceptors, chemoreceptors, and the kidneys.
Baroreceptors are rigid and static nerve endings that are contained along the arterial walls and send out messages along the nerve pathway.
Chemoreceptors are located along the walls of the arteries and monitor changes in oxygen level.
The kidneys play a role in regulating blood pressure by absorbing salts and water.
The heart is the body's pump, which regulates the flow of vitally needed oxygen to cells of the body.

The oncoming sound waves have a higher pitch owing to high frequency and closeness of waves.
The oncoming sound waves have a higher pitch owing to low frequency and closeness of waves.
The whistling sound of the locomotive as it approaches and passes can be explained by the Doppler effect.
The high-pitched sound of the ambulance as it approaches and passes can be explained by the Doppler effect.
Trains and ambulances make distinctly loud noises.
Low-frequency waves make high-pitched sounds.
High-frequency waves make low-pitched sounds.
The Doppler effect explains the rationale for why the sound is heard initially more strongly and then faintly after a moving object has passed.

Changes in the ECG are typically used for diagnosis of abnormal cardiac rhythm.
The signal has a characteristic record called the electrocardiogram.
The wave of excitation starts at the SA node.
The wave of excitation spreads through the heart wall and is accompanied by electrical changes.
Electrical currents within the body are due to electrostatic charges set off by the heart.
The electrocardiogram systematically and rather quickly measures the stages at which the wave of excitation occurs within the heart and records it.
The wave of excitation is detected on the surface of the body and measures the atrial excitation of the heart.
The electrical currents within the body are in direct relation to the wave of excitation measured by the electrocardiogram.
