The movement of glucose from the lumen into the proximal tubule cells is an example of

The proximal convoluted tubule is the site of glucose and amino acid reabsorption. Establish sodium concentration gradient between tubular cells and tubular lumen sodium and glucose moved into tubular cell. Substances that are cotransported into proximal convoluted tubule cells include glucose molecules with sodium ions. 

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
