Peptide hormones and small amounts of albumin make it through the [[Glomerulus and Bowmans Capsule - Anatomy & Physiology#Function of Renal Corpuscle|glomerular filtration barrier]] and these need to be reabsorbed. The reabsorption occurs via '''endocytosis''' in the [[Proximal Tubule - Anatomy & Physiology| proximal tubules]]. They are then broken down to amino acids in the epithelial cell cytoplasm and move via facilitated diffusion into the interstial fluid. The reabsorption of protein is usually complete though it is normal to detect small quantities of protein in the urine of some mammals e.g. the dog
