air sac in the lung

hyaline cartilage

Translucent bluish white cartilage consisting of cells embedded in an apparently homogeneous matrix, present in joints and respiratory passages, and forming most of the fetal skeleton

pseudostratified ciliated columnar epithelium

lines the respiratory tract

simple squamous epithelium

cardiac muscle

Involuntary muscle tissue found only in the heart.

striated muscle

A muscle that appears banded.

Tissue that stores fat.

lacuna

an empty space or missing portion

a collection of 4 cells in the same lacuna is called?

locule

Basal surface (basement membrane)

surface attached to underlying tissue; provide nutrient exchange.

fat cell

reticular tissue

Forms internal supporting framework of soft organs such as the spleen

reticular fiber
