Blood Pressure
Lub-dub! Lub-dub! Lub-dub! This sound is made by the rapid contracting
and extending of the chamber doors on the inside of the heart. This
ventricular contracting injects roughly 70 mL of blood into a vascular
system with a given volume at differing pressure.
Blood pressure refers to the pressure in the arterial system; and it is
typically taken in the brachial artery of the arm because the pressure at
different places along the circulatory route is different. Blood pressure is
simply the force that the blood exerts in all directions within any given
,area and is the basis for the movement of blood from the heart, through
the body, and back to the heart. This pressure is commonly expressed as
a ratio of the systolic pressure over the diastolic pressure.
The systolic pressure or "high peak" pressure takes place within the
arterial system as ventricles contract and force blood into the arteries.
The di - answer ✅✅1. What is the main idea of the passage?
A. Blood pressure overall measures the elasticity of the arteries near the
heart as they stretch to accommodate expelled blood.
B. Blood pressure within the arterial system takes into account that
pressure is different at varying locations.
*C. Blood pressure is simply the force that the blood exerts in all
directions within any given area, measured as a ratio.
D. Blood pressure represents the pulse difference between ventricular
contractions.
2. Which statement is not a detail from the passage?
, *A. The ventricular contraction asserts capillary pressure that is about 70
mm Hg.
B. The pressures at different places in the circulatory system are different.
C. Increase in blood pressure can occur if arterial walls lose some of their
elasticity.
D. Blood pressure is expressed as a ratio of systolic over diastolic
pressure.
3. What is the meaning of the word elasticity in the last paragraph?
*A. Something that is able to resist and be flexible
B. Something that is like plastic
C. Something that is dynamic and electrifying
D. Something that is silly
