Verified
Passage of proteins into Bowman capsule is prevented by
A) the size of the capillary pores.
B) the size of the filtration slits in the podocytes.
C) the size of the proteins.
D) All of the choices are correct.
Bowman Capsule
A cup-like sac at the beginning of the tubular component of a nephron in the kidney, playing a crucial role in the filtration of blood to form urine.
Filtration Slits
are gaps between the podocyte processes in the kidneys through which blood filtration occurs.
Capillary Pores
Capillary pores refer to tiny openings in the surface of materials or biological tissues that facilitate the movement of fluids through capillary action.
- Explain the cellular and molecular mechanisms involved in the transport of substances across nephron segments, including active and passive processes.
- Explain the makeup of glomerular filtrate and identify how it diverges from plasma composition.

Final Answer :
D
Explanation :
The size of the capillary pores, the size of the filtration slits in the podocytes, and the size of the proteins all contribute to preventing the passage of proteins into the Bowman capsule. These factors work together to ensure that only small molecules like water, ions, and small nutrients pass through, while larger molecules like proteins are retained in the bloodstream.
