Textbook Problem

There is a linear True_______False ____________

relationship between

the degree of ascent

and the degree

of pulmonary

vasoconstriction and

hypertension.

Summary Introduction

To review:

Whether the following statement, “There is a linear relationship between the degree of ascent and the degree of pulmonary vasoconstriction and hypertension,” is true or false.

Introduction:

Pulmonary vasoconstriction, Euler–Lilijstrand mechanism, or the hypoxic pulmonary vasoconstriction (HPV) is an event in which there is constriction of small pulmonary arteries due to low levels of oxygen.

Explanation

There is a progressive increase in the HPV of an individual when the person goes to a higher altitude, which then, increases pulmonary hypertension. As an individual goes higher above the sea levels, the levels of oxygen decrease. The body of the individual adjusts itself to the surroundings and reallocates the supply of blood to a less perfused region of the lungs by HPV...
