Answer 3

Lining tissue, covers the surface of organs, cavities and tubes

Question 4

What are some features of epithelial tissue?

Answer 4

Cells packed closely together
No blood vessels (but may have nerve endings)
Cells sit on basement membrane

What is the structure of squamous tissue?

Answer 6

Flattened cells on a basement membrane

Question 7

What is the function of squamous tissue?

Answer 7

lining tissue
covers the surface of organs, cavities and tubules
thin layer of cells for exchange

Question 8

Answer 8

walls of alveoli
blood vessels
lining of renal (bowmans) capsule of the nephron

Question 9

What is the structure of cuboidal tissue?

Answer 9

cells have cube shape
tissue is one cell thick

Question 10

What is the function of cuboidal tissue?

Answer 10

secretion and reabsorption

Question 11

Answer 11

kidney tubules

glandular ducts, eg saltatory glands

Question 12

What is the structure of columnar tissue?

Answer 12

cells are elongated, column shaped

some have microvilli

Question 13

What is the function of columnar tissue?

Answer 13

Microvilli increase surface are for absorption

Answer 15

cells are elongated, column shaped

cells have cilia

Question 16

trachea
bronchi
fallopian tubes

Question 18

What is the structure of glandular tissue?

Answer 18

secretory epithelial cells, secrete substances and organise themselves into gland shapes

Question 19

What is the function of glandular tissue?

Answer 19

secrete hormones, saliva and mucus

Question 20

Where is glandular tissue found in the body?

Answer 20

salivatory glands, pancreas

Question 21

What are some features of muscle tissue?

Answer 21

they can contract
inside the cells are protein fibres made of actin and myosin

Question 22

What are the 3 types of muscle tissue?

Answer 22

Skeletal muscle, smooth muscle, cardiac muscle

Question 23

What is the structure of skeletal muscle?

Answer 23

attached to bones
muscle cells are joined together to form fibres
the stripes are caused by overlapping protein molecules
voluntary

Question 24

What is the function of skeletal muscle?

Answer 24

moves bones
maintains posture and body position
supports soft tissue

Question 25

Where is skeletal tissue found in the body?

Answer 25

attached to the bone by tendons generates locomotion in animals/mammals

Question 26

What is the structure of smooth muscle?

Answer 26

unstriated, individual cells that can shorten in length cells do not have stripes involuntary

Question 27

What is the function of smooth muscle?

Answer 27

rhythmic involuntary contraction, less powerful than skeletal

Question 28

Where is smooth muscle found in the body?

Answer 28

walls of hollow organs walls of blood vessels bladder skin

Question 29

What is the structure of cardiac muscle?

Answer 29

cells have stripes striated and branched fibres cells are joined together by intercalated discs involuntary

Question 30

What is the function of cardiac muscle?

Answer 30

rhythmic contractions to pump blood through the heart

Question 31

Where is cardiac muscle found in the body?

Answer 31

the heart

Question 32

What is the function of connective tissue?

Answer 32

connects, supports or separates tissues and organs

Question 33

What is the structure of connective tissue?

Answer 33

contains cells and elastic and collagen fibres in an extracellular fluid between the fibres are fat storing cells and cells of the immune system

Question 34

What is an example of connective tissue?

Answer 34

blood, bone, tendon

Question 35

What is the function of nervous tissue?

Answer 35

generates and transmits electrical impulses, sensory input, control muscles and glands, homeostasis

Question 36

What is the structure of nervous tissue?

Answer 36

made of nerve cells called nephrons and glial cells
