Most systemic venous blood is both oxygen poor and nutrient poor. however, systemic venous blood that is oxygen not poor and nutrient rich occurs in
a) the pulmonary veins.
b) the renal vein.
c) the hepatic portal vein.
d) superficial veins of the limbs.

the correct answer is C) the hepatic portal vein.

Explanation:

The portal vein is not a true vein, because it conducts blood to capillary beds in the liver and not directly to the heart. It is a major component of the hepatic portal system, one of only two portal venous systems in the body – with the hypophyseal portal system being the other.

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
