The correct answer is Glucose, as it is a small molecule that can pass through the glomerulus into Bowman’s capsule during the filtration process. The glomerulus acts as a filtration barrier, allowing only small molecules and ions to pass while retaining larger components of the blood, such as red blood cells and platelets. Red blood cells and platelets are both too large to be filtered and therefore do not enter Bowman’s capsule. Albumin, a protein, is also retained in the bloodstream under normal circumstances; its presence in urine can indicate kidney issues.

Glucose is a small molecule that is normally filtered through the glomerulus into Bowman’s capsule.

Red blood cells are too large to pass through the glomerular filtration barrier and are retained in the bloodstream.

Platelets are also too large to be filtered through the glomerulus and remain in the circulatory system.

Albumin is a protein that is generally too large to pass through the glomerulus, and its presence in urine indicates kidney damage.
