Tissue Structure and Functions Flashcards
What is the general structure of epithelial tissue?
Epithelial tissue is composed of cells that are closely packed together and arranged in one or more layers. The cells are connected to each other through tight junctions that form a barrier and help to regulate the passage of substances between cells.
What are the general functions of epithelial tissue?
The general functions of epithelial tissue include protection, secretion, absorption, filtration, and sensory reception.
What classifies as epithelial tissue?
Epithelial tissue includes skin, blood vessels, sweat glands, and mucous membranes.
What is the general structure of connective tissue?
Connective tissue is composed of cells that are embedded in an extracellular matrix made up of proteins, carbohydrates, and lipids. The extracellular matrix also contains fibers such as collagen and elastin.
What are the functions of connective tissue?
The functions of connective tissue include support, protection, insulation, and transportation of substances throughout the body.
What classifies as connective tissue?
Connective tissue includes bone, cartilage, fat, tendon, and ligament.
What is skeletal muscle?
skeletal muscle is a type of muscle tissue that is composed of long, cylindrical cells that contract when stimulated. It is attached to bones and is involved in the movement of the body and the maintenance of posture.

What is cardiac muscle?
Cardiac muscle is a type of muscle tissue that is found in the walls of the heart and is responsible for the rhythmic contractions of the heart.
What is smooth muscle?
Smooth muscle is a type of muscle tissue that is found in the walls of hollow organs and is responsible for the contraction and relaxation of muscles in the body.
What is the general structure of nervous tissue?
Nervous tissue is composed of neurons and supporting cells (glia). Neurons are specialized cells that transmit electrical signals throughout the body.
What are the functions of nervous tissue?
The functions of nervous tissue include the transmission of electrical signals, the coordination of body movements, and the regulation of physiological processes.
What classifies as nervous tissue?
Nervous tissue includes the brain, spinal cord, and nerves.
Simple Cuboidal
Located in Kidney tubules. Function is to secrete and absorb
Simple Squamous
Located in the air sacs of the lungs as well as blood vessels and the lining of the heart. The function is allowing materials to pass through it by diffusion and filtration. Also secretes lubricant like substance.
