Animal Tissue Flashcards
also called epithelium, forms the external coverings and internal linings of many organs and covers the entire surface of the body
serve as a protective function
Epithelial tissue
thin, flat cells that are closely packed
lines the cavities of the mouth, esophagus, alveoli, and blood vessels.
Squamous epithelium
contains cube-shaped cells that are roughly the same height as width.
Found in the salivary glands, sweat glands and lines the kidney tubules.
• Absorption, secretion and excretion
Cuboidal epithelium
has cells resembling rectangular pillars or columns, with nuclei usually located near the bottom of each cell
lines portions of the lumen of the digestive tract
Columnar epithelium
when columnar epithelial tissues have cilía present in the lining of the trachea, kidney tubules etc.
rhythmic movement of the cilia helps in the movement of material in one direction
Ciliated epithelium
a layer that is only one cell thick
Simple
multiple layers of cells
Stratified
tissue appears to have multiple layers of cells but actually has only one.
Pseudostratified
supports and connects the tissues of the body and vary considerably in structure and composition.
Connective tissue
Enables movement of structures within the body and movement of the entire person/animal
Muscular tissue
Located throughout the body and under voluntary control, functions in movement of the structures of the body, and/ the body as a whole, e.g. by walking, running, etc.
Skeletal muscle
Located throughout the body and under voluntary control, functions in movement of the structures of the body, and/ the body as a whole, e.g. by walking, running, etc.
Skeletal muscle
which is found only in the heart and is important for effective blood-flow through the heart.
Cardiac muscle
Involuntary muscle tissue located around the walls of many internal structures such as the stomach anc Intestines and important for alding the passage of materials/luics through those structures
Smooth muscle
Involuntary muscle tissue located around the walls of many internal structures such as the stomach anc Intestines and important for alding the passage of materials/luics through those structures
Smooth muscle
