Tissue
a group of similar celss specialized to perform a specific function
primary types: epithelial, connective, muscle,and nervous
Epithelial Tissue
one of the primary tissues; covers the surface of the body and lines body cavaties, ducts, a vessels
Connective tissue
primary tissue; form and function vary extensively; functions include support, storage, and protection.
Muscle Tissue
highly specialized to contract or shorten to produce movemnt
ex: skeletal, cardiac, smooth
Nervous Tissue
made up of cells called neurons and supporting cells
gland
organ specialized to secrete or excrete substances for further use in the body for elimination
macrophage
cell particularly abundant in lymphatic and connective tissue; important in the immune response as an antigen presenter to T-cells and b-cells
collagen
found in bones, cartilage, and tendons and is most abundant protein in the body
