simple cuboidal epithelium are found where

Answer 14

secretion and absorption found in the glands and kidney tubules

Question 15

Answer 15

secretion and absorption found past the oesophagus in the GI tract

Question 16

oesophagus tract and and trachea and large respiratory airways

Question 18

what are the 3 types of specialised connective tissue

Answer 18

blood, bone and cartilage

Question 19

connective tissue proper surrounds the muscle and also found under skin
can be classified based on what

Answer 19

abundance of fibres and the way they are organised

Question 20

what are the 3 major types of connective tissue proper

Answer 20

loose arteriolar, dense irregular and dense regular

Question 21

which type of connective tissue contains:

lots of ground substance

Answer 21

loose arteriolar tissue (looks white)

Question 22

which type of connective tissue contains:

a variety of different cells including macrophages, fibroblasts and adipocytes

Answer 22

loose arteriolar tissue

Question 23

which type of connective tissue contains:

doesn’t have that many fibres (collagen and elastic)

Answer 23

loose arteriolar tissue

Question 24

which type of connective tissue contains:

fibres in all different direction found under epithelium

Answer 24

loose arteriolar tissue

Question 25

which type of connective tissue contains:

little ground substance

Answer 25

dense irregular and dense regular

Question 26

what is the difference between dense irregular and dense regular connective tissue

Answer 26

dense regular has densely packed bundles of collagen fibres in parallel rows
dense irregular has it in different directions so it can resist stretching

Question 27

where is dense irregular tissue found

Answer 27

in the dermis layer of skin

Question 28

where is dense regular connective tissue found

Answer 28

in tendons and ligaments as stretch will always come from the same direction

what are the 3 types of muscle

Answer 29

skeletal, smooth and cardiac
