Verified step by step guidance

Understand the function of capillaries: Capillaries are small blood vessels where the exchange of gases, nutrients, and waste occurs between blood and tissues.

Identify the types of capillaries: There are three main types of capillaries - continuous, fenestrated, and sinusoid.

Define continuous capillaries: These have a continuous basement membrane and endothelial lining, allowing only small molecules to pass through.

Define fenestrated capillaries: These have pores in the endothelial cells, allowing for increased permeability, but the basement membrane remains continuous.

Define sinusoid capillaries: These have a discontinuous basement membrane and large openings, allowing for the passage of larger molecules and cells, such as in the liver, spleen, and bone marrow.
