Avascularity means that epithelial tissues must be relatively thin because the process of _________ provides the substances.

• osmosis
• diffusion
• active transport
• filtration

Epithelial tissues must be highly regenerative because they are found in areas of high -

• friction

• pressure
• temperature
• moisture

• cells ; EC matrix

Polarity means that there is always a(n) ________________ surface.

• apical

• fibrous

• interior

• positive

The function of the basement membrane is to ______________________

• store energy
• produce hormones
• maintain tissue boundaries

• regulate blood flow

Why does bone heal faster than cartilage in specific terms of the tissue features they have?

• Bone has a better blood supply

• Bone is less cellular than cartilage.
• Cartilage heals faster due to its flexibility.
• Cartilage has a higher blood supply than bone.
