Final answer:
The term for controlling blood flow in a vein by compression is Phlebostasis, which impacts the vein by increasing blood pressure, reducing blood flow, and increasing return of blood to the heart.
Step-by-step explanation:
The term for controlling blood flow in a vein by compression is Phlebostasis. In the context of the multiple-choice options provided, none of the terms directly refer to venoconstriction, which is the process where veins constrict to regulate blood flow. Venoconstriction results in increased blood pressure within the vein, decreased blood flow within the vein, and increased return of blood to the heart due to the compression and narrowing of the vein's lumen.
As for the specific impact of venoconstriction as given in the supporting material, the correct answer is d. all of the above: it increases blood pressure within the vein, reduces the volume of blood flow within the vein, and increases the return of blood to the heart due to the higher pressure gradient created.
