Functions: Allow material to pass through by diffusion and filtration, and secretes lubricating substance
Location: Air sacs of lungs and the lining of the heart, blood vessels, and lymphatic vessels
Simple Squamous Epithelium
Functions: Secretes and Absorbs
Location: In ducts and secretory portions of small glands and in kidney tubules
Simple Cuboidal Epithelium
Functions: Absorbs; it also secretes mucous and enzymes
Locations: Ciliated tissues are in bronchi, uterine tubes, and uterus; smooth (non ciliated tissues) are in the digestive tract, bladder
Simple Columnar Epithelium
Function: Secretes mucus; ciliated tissue moves mucus
Location: Ciliated tissue lines the trachea and much of the upper respiratory tract
Pseudostratified Columnar Epithelium
Function: Protects against Abrasion
Location: Lines the esophagus, mouth, and vagina
Stratified Squamous Epithelium
Function: Protective Tissue
Location: Sweat Glands, Salivary Glands, and the mammary glands
Stratified Cuboidal Epithelium
Function: Secretes and Protects
Location: The male urethra and the ducts of some glands
Stratified Columnar Epithelium
Function: Allows the urinary organs to expand and stretch
Location: Lines the bladder, urethra, and the ureters
Function: Strength, elasticity, support
Location: Also called "packing material" of the body; in subcutaneous layer deep to skin; papillary (superficial) region of the dermis of skin; lamina propria of mucous membrane; around blood vessels, nerves, and body organs.
Loose / Areolar Connective Tissue
Function: Reduce heat loss through skin; energy reserve; support and protects organs
Location: subcutaneous layer to skin; around heart and kidneys, yellow bone marrow, padding around joints and behind eyeball and eye socket.
Loose / Adipose Connective Tissue
Function: forms stroma of organs; binds smooth muscle tissue cells; filters and removes worn-out blood cells in spleen and microbes in lymph nodes.
Location: Stroma (supporting framework) of liver, spleen, lymph nodes; red bone marrow; reticular lamina of basement membrane; around blood vessels.
Reticular Connective Tissue
Function: Provides strong attachment between various structures. Tissue structure withstands pulling (tension) along long axis of fibers.
Location: Forms tendons (muscle-bone), most ligaments (bone-bone), & aponeuroses (sheetlike tendons muscle-muscle and muscle-bone)
Dense Regular Connective Tissue
Function: Provides tensile (pulling) strength in many directions
Location: In sheets, such as fasciae (tissue beneath skin and around muscles and other organs), reticular (deep) regions the dermis of the skin, membrane capsules around various organs (kidneys, liver, testes, lymph nodes) also in heart value
Dense Irregular Connective Tissue
Function: stretching of various organs; is strong and can recoil to original shape after being stretched.
Location: Lung tissue (recoiling exhaling) and walls of arteries; trachea, bronchial tubes, suspensory ligaments of penis, some ligaments between vertebrae.
Elastic / Dense Connective Tissue
Function: Provides smooth surface for movement at joints, flexibility, and support; weakest type of cartilage.
Locations: Most abundant cartilage in body; at ends of long bones, anterior ends of ribs, nose, parts of larynx, trachea, bronchi & tubes; embryonic and fetal skeleton.
Function: Support and joining structures together. Strength and rigidity make it the strongest type of cartilage.
Location: Pubic symphysis (where hip bones join anteriorly, intervertebral discs, menisci (cartilage pads) of knee, portions of tendons that insert into cartilage.
Function: Provides strength and elasticity; maintains shape of certain structures.
Location: Lid on top of larynx (epiglottis); part of external ear (auricle), auditory (eustachian) tubes
Function: Support, protection, storage; house blood-forming tissue; serves as levers that act with muscle tissue to enable movement.
Locations: Bones of the body
Bone / Osteon Tissue
Function: RBC transport oxygen and some carbon dioxide; white BC carry on phagocytosis and mediate allergic reactions and immune system responses; platelets: essential for blood clotting.
Location: within blood vessels and chambers of hear
Blood (Connective Tissue)
Function: Motion, Posture, Heat Production, Protection
Location: Usually attached to bones by tendons
Skeletal Muscle Tissue
Function: Pumps blood to all parts of body
Location: Heart Wall
Cardiac Muscle Tissue
consist of elongated cells (myocytes) that can use ATP to generate force.
Function: Motion (constriction of blood vessels and airways, propulsion fo foods through GI tract, contraction of urinary bladder and gallbladder.
Location: Iris of eyes; walls of hollow internal structures such as blood vessels, airways to lungs, stomach, intestines, gallbladder, urinary bladder, and uterus.
Smooth Muscle Tissue
Function: Exhibits sensitivity to various types of stimuli; converts stimuli into nerve impulses (action potentials); conducts nerve impulses to other neurons, muscle fibers, or glands
Location: Nervous system
Consist of relatively few cells and an abundant extracellular matrix of ground substance and protein fibers. Do not occur on free surfaces and a nerve supply (except cartilage) and highly vascular (except cartilage, tendons, and ligaments).
Derived primarily from mesenchymal cells. Cell types fibroblasts (secrete extracellular matrix), macrophages (perform phagocytosis), plasma cells (secrete antibodies), mast cells (produce histamine), adipocytes (store fate) and white blood cells.
