Thorax
The proximal convoluted tubule is a structure within the kidney nephron that plays a significant role in the reabsorption of important products that have been filtered from the blood. One of the key features of this structure is its lining. The cells that line the tubule are responsible for the transport of substances across the membrane. These cells and their collective efforts would be an example of which of the following levels?
Tissue Level
