Connective Tissue Flashcards

1
Q

How is epithelial tissue different from connective tissue?

A

Epithelial tissue is avascular with no blood supply. Connective tissue is vascular and thus are rich in blood vessels, except for cartilages and tendons. Epithelial tissue also doesn’t have nerve supplies. Connective tissue is innervated except for cartilage.

Q

Functions of CT

A
  • Connects tissues and organs: ligaments and tendons
  • Forms Skeleton: bone and cartilage
  • Carries and stores nutrients: blood, bone, adipose (fat)
  • Supports blood vessels and nerves: loose areolar CT

The dermis is made of this tissue

A

Dense irregular tissue

24
Q

The epidermis is made of this tissue

A

epithelial; stratified squamous

25
Q

Why is blood considered a connective tissue?
