The three filtration barriers that substances must pass through when leaving the blood and entering the tubule lumen are the glomerular capillary endothelium, the epithelium of Bowman's capsule, and which other structure? A. efferent arteriole
B. macula densa
C. basal lamina
D, granular cells

C. basal lamina

Explanation:

Basal Lamina is considered as a layer of extracellular matrix located on the basal surface of epithelial cells, though closely related to the plasma membrane on the epithelial and endothelial cell bases, it is secreted by the epithelial cells and surrounds muscle and adipose tissue.

Functions of Basal Lamina are:

1. It supports the tissue structure.

2. It acts as a barrier to permeability, which helps in regulating the movement of molecules and cells.

3. It also acts as filter that allows small molecules to enter the urine in kidney cells.

4. In epidermis cells, it helps to prevent the connective tissue cells from entering the epidermis and at the same time allows the movement of white blood cells

Hence, it is therefore considered to be among the three filtration barriers that substances must pass through when leaving the blood and entering the tubule lumen

panem is a communist totalitarian dictatorship where all the resources and how they are allocated belongs to the capitol. the districts exist only to provide goods and services for the capital and most of the citizens live in poverty. it is a police state where the "peacekeepers" use force and threats to keep the people under control. dissent is outlawed and those who disobey the law are executed, flogged, or turned into avoxes. the games are another means in which the ruling elite in the capitol exert their power over the districts. when reading the books i drew parallels between panem and the soviet union and north korea. in no way is panem capitalist. the people in the capitol are wealthy but the majority of them are involved in the government somehow. it was the same way in the former soviet union where bigwigs in the communist party and high ranking government officials were given access to goods, services, medical treatments not available to the general public. if you think panem has a capitalist economy you need to brush up on your economics.
