Function: allows materials to pass by diffusion and filtration in sires where protection is not important; secretes lubricating substances in serosae.

Location: air sacs of lungs, lymph and blood vessels, serosae, lining of heart

Connective Tissue Proper

Bone

Cartilage

Blood

Function: secretion and absorption

Location: kidney tubule, ducts and secretory part of small glands, and ovaries.

Function: Absorption; secretion of mucus, enzymes, and other substances; ciliated type propels mucus by ciliary action

Location: digestive tract, gallbladder, oviducts, some regions of the uterus

Function: Protects underlying tissues in areas subjected to abrasion

Location: Non-keratinized type forms the moist linings of the esophagus, mouth, and vagina; keratinized variety forms the epidermis of the skin, a dry membrane.

Simple squamous epithelium: allows passage of materials, secretes lubricating substances in serosae

located in kidney glomeruli, air sacs of lungs, lining of heart, blood vessels, lymphatic vessels, lining of ventral body cavity

Function: wraps and cushions organs; its macrophages phagocytize bacteria; plays important role in inflammation; holds and conveys tissue fluids

Location: Widely distributed under epithelia of body. Forms lamina propria of mucous membrane; packages organs; surrounds capillaries.

Function: Provides reserve fuel; insulates against heat loss; supports and protects organs.

Location: Under skin; around kidney and eyeballs; within abdomen; in breast

Function: Fibers form a soft internal skeleton (stroma) that supports other cell types, including white blood cells, mast cells, and macrophages.

Location: Lymphoid organs (lymph nodes, bone marrow, and spleen).

Function: attaches muscles to bone or to muscles; attaches bones to bones; withstands great tensile stress when pulling force is applied in one direction.

Location: tendons, most ligaments, aponeuroses

Function: supports and reinforces; has resilient cushioning properties; resists compressive stress

Location: forms most of the embryonic skeleton; covers the ends of long bones in joint cavities; forms costal cartilages of the ribs; cartliages of the nose, trachae, and larynx.

Function: Maintains the shape of a structure while allowing great felxibilty

Location: Supports the external ear (pinna); epiglottis

Function: Bone supports and protects; provides levers for the muscles to act on; stores calcium and other minerals and fat; marrow inside bones is the site for blood cell formation

Location: Bones

Function: voluntary movements; locomotion; manipulation of the environment; facial expression; voluntarey control

Location: In skeletal muscles attached to bones or occasionally to skin

Function: As it contracts, it propels blood into the circulation; involuntary control

Location: The walls of the heart

Function: Propels substances or object along internal passageways; involuntary control

Location: Mostly in the walls of hollow organs

Function: Transmits electrical signals from sensory receptors and to effectors which controls hte activity.

Location: Brain, spinal cord, and nerves.
