Lecture 14: Fibrous Connective Tissue Flashcards

(14 cards)

1
Q

Functions of Connective Tissues

A
  • structural framework of the body
  • supports and interconnects other tissues
  • also: protection, NRG storage, transport, defense

Q

Loose Connective Tissue

A
  • areolar
  • support and bind other tissues, defend from infection
  • found immediately beneath membranous epithelia (lamina propria)

Q

Adipose Connective Tissue

A
  • loose CT
  • abundant adipocytes and sparse ECM
  • reserve energy source and insulates against heat loss
  • padding/cushioning organs

Q

Reticular Connective Tissue

A
  • loose CT
  • rich in RETICULAR FIBERS
  • open framework = labyrinth for holding free cells
  • houses blood cells and immune cells outside of blood/lymphatic vessels
