The exchange of substances between the mother and embryo takes place in the placenta. The placenta is a temporary organ that develops during pregnancy to provide nutrients and oxygen to the embryo and remove waste products. This exchange is crucial for the growth and development of the embryo.
The device you are referring to is called a calorimeter. It is specifically designed to measure the heat exchange between substances in a thermally isolated environment.

Counter current exchange allows for a more efficient exchange of substances between two fluids by maintaining a concentration gradient along the exchange surface. This results in a greater rate of diffusion compared to simple diffusion. It also helps to conserve energy by minimizing the loss of substances from the gradient.
Blood carries oxygen, nutrients, hormones, and waste products. The exchange of substances between blood and body tissues occurs in the capillaries, which are tiny blood vessels with thin walls that allow for the transfer of molecules. Oxygen and nutrients are delivered to tissues, while waste products are picked up and taken away by the blood for disposal.

They exchange water, oxygen and carbon dioxide, as well as nutrient and waste chemical substances between blood and surrounding tissues.
