Tissue functions and locations

Question 1

simple squamous epithelium

Answer 1

• allows material to pass by diffusion and filtration in sites where protection is not important; secretes lubrication substances in serosae
• air sacs of lungs; lining of heart, blood vessels, and lymphatic vessels

Question 2

simple cuboidal epithelium

Answer 2

• secretion and absorption
• kindey tubules; ovary surface

Question 3

simple columnar epithelium

Answer 3

• absorption; secretion of mucus, enzymes, and other substances
• non-ciliated type lines most of the digestive tract, gallbladder, and excretory ducts of some glands; ciliated variety lines small bronchi, uterine tubes, and some regions of the uterus

Question 4

pseudostratified columnar epithelium

Answer 4

• secretes substances, particularly mucus; propulsion of mucus by ciliary action
• non-ciliated type in male’s sperm-carrying ducts and ducts of large glands; ciliated variety lines the trachea, most of the upper respiratory tract.

Question 5

stratified squamous epithelium

Answer 5

• projects underlying tissues in areas subjected to abrasion
• non-keratinized type forms the moist linings of the esophagus, mouth, and vagina; keratinized variety forms the epidermis of the skin, a dry membrane

Question 6

stratified cuboidal epithelium

Answer 6

• function
• largest ducts of sweat glands, mammary glands, and salivary glands

Question 7

stratified columnar epithelium

Answer 7

• protection; secretion
• small amounts in male urethra and in large ducts of some glands

Question 8

transitional epithelium

Answer 8

• stretches readily and permits distension of urinary organ by contained urine
• lines the ureters, urinary bladder, and part of the urethra

Question 9

embryonic connective tissue: mesenchyme

Answer 9

• gives rise to all other connective tissue
• primarily in embryo

Question 10

connective tissue proper: loose connective tissue, areolar

Answer 10

• wraps and cushions organs; holds and conveys tissue fluid
• surrounds capillaries; forms lamina propria of mucous membranes

Question 11

CTP: loose connective tissue, adipose

Answer 11

• supports and protects organs; insulated against heat loss
• under skin; in breasts

Question 12

CTP: loose connective tissue, reticular

Answer 12

• fibers form a soft internal skeleton (stroma) that supports other cells types, including white blood cells, mast cells, and macrophages
• lymphoid organs (lymph nodes, bone marrow, and spleen)

Question 13

CTP: dense connective tissue, dense regular

Answer 13

• attached bones to bones; attaches muscles to bones
• tendons, most ligaments, aponeuroses

Question 14

CTP: dense connective tissue, dense irregular

Answer 14

• able withstand tension exerted in many directions; provides structural strength
• dermis of the skin; submucosa of digestive tract.

Question 15

CTP: dense connective tissue, elastic

Answer 15

• allow recoil of tissue following stretching; maintains pulsatile flow of blood through arteries
• walls of large arteries; within of the bronchial tubes

Question 16

cartilage: hyaline

Answer 16

• supports and reinforces; resists compressive stress
• forms costal cartilages of ribs; covers the ends of longs bones in joint cavities

Question 17

cartilage: elastic

Answer 17

• maintains the shape of a structure while allowing great flexibility
• supports the external ear (auricle); epiglottis

Question 18

cartilage: fibrocartilage

Answer 18

• tensile strength with the ability to absorb compressive shock
• intervertebral discs; discs of knee joint

Question 19

bones (osseous tissue)

Answer 19

• bone supports and protects; provides levers for the muscles to act on
• bones

Question 20

blood

Answer 20

• transport of respiratory gases, nutrients, wastes, and other substances
• contained within blood vessels

Question 21

skeletal muscle tissue

Answer 21

• voluntary ,movement; locomotion
• in skeletal muscles attached to bones or occasionally to skin

Question 22

cardiac muscle tissue

Answer 22

• as it contracts, it propels blood into the circulation; involuntary control
• the walls of the heart

Question 23

smooth muscle tissue

Answer 23

• propels substances or objects (foodstuffs, urine, a baby) along internal passageways; involuntary control
• mostly in the walls of hollow organs

Question 24

nervous tissue

Answer 24

• neurons transmit electrical signals from sensory receptors and to effectors (muscles and glands); supporting cells support and protect neurons
• brain, spinal cord, and nerves
