Which statement explains blood pressure?

blood pressure is highest in the veins near the heart.

blood pressure is highest in the arteries near the heart.

blood pressure is highest in the veins farthest away from the heart.

blood pressure is highest in the arteries farthest away from the heart.

The answer is "Blood pressure is highest in the arteries near the heart. I took the test and got a 100.

The correct answer is option B, Blood pressure is highest in the arteries near the heart.

Explanation:

In the arteries, the hydrostatic pressure near the heart is very high while in the case of arterioles the rate of flow reduces (but pressure increase) as the openings of the arterioles become narrow. Thus these two tubules have thick muscular walls. While the veins and venules have lower pressure and thus their walls are also thin and less muscular.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
