During pregnancy, the developing fetus obtains all of its nutrients (including oxygen) from its parent. As the fetus grows, its nutrient needs increase, which means the parent’s nutrients are depleted at an increasing rate. To accommodate for this increasing nutritional depletion, pregnant parents undergo a number of physiological changes aimed to support their own homeostasis by obtaining more nutrients and improving nutrient distribution throughout the body. However, these changes, in turn, supply the fetus with even more nutrients, facilitating further growth. Broadly speaking, these physiological changes that pregnant parents undergo are an example of what type of feedback mechanism?
