The pulmonary circulation conveys blood that is low in oxygen to the lungs before returning back to the left side of the heart.
<h3>The pulmonary circulation</h3>
The circulatory system is divided into two main parts namely:
- pulmonary circulation and
The pulmonary circulation involves the movement of blood between the lungs and the heart.
Blood from the systemic circulation returns to the right side of the heart where it is pumped through the pulmonary artery into the lungs to be oxygenated.
After oxygenation has taken place in the lungs, the blood returns to the left side of the heart through the pulmonary veins.

Explanation:
___________
An INHIBITORY Signal is sent between neurons when (A)Na+ rushes into the neuron.
Explanation:
- When one spot of membrane supports an action potential, lots of \text {Na}^+Na+start text, N, a, end text, start superscript, plus, end superscript ions hurry into the cell by that spot.
- These ions radiated out sideways into the cell and can depolarize a nearby spot of membrane, stimulating the hole of voltage-gated sodium channels and causing the nearby spot to support its action potential.
- The action potential can only move in one direction – from the cell body towards the axon terminal – because a spot of membrane that has just experienced one action potential is in a “refractory period” and cannot withstand another.
