Question 1

Tissue that cells are compactly arranged with little or no intercellular space between them.

Answer 1

EPITHELIAL TISSUE

Question 2

They function best for covering and protection

Answer 2

EPITHELIAL TISSUE

Question 3

This tissue is found lining the outer and inner surfaces of the body such as the skin, lining of the digestive system, living of glands, blood vessels, mouth, nose, and anus.

Answer 3

EPITHELIAL TISSUE

Question 4

Epithelial tissue that only has one layer of cells

Answer 4

Simple Epithelium

Question 5

Epithelial tissue that only has many layer of cells

Answer 5

Stratified Epithelium

Question 6

Endothelium of Artery

Answer 6

Simple Squamous Epithelium

• flat cells
• irregular outline of the cells, neighboring cells fit into each other
• cheek toothpick

Question 7

Kidney/Liver

Answer 7

Simple Cuboidal Epithelium

• short and cube-like cells

Question 8

Small Intestine

Answer 8

Simple Columnar Epithelium

• cells are elongated and prismatic due to the pressure exerted by the neighboring cells
• taller and narrower than those of cuboidal epithelium.

Question 9

Skin

Answer 9

Stratified Squamous Epithelium

• structure consists of several layers of cells
• basal cells are elongated and receives more nutrition and capable of repeated cell division
• as cells approach the free surface, they eventually become flattened due to wear and tear
• being farther way from the source of nutrition; these cells gradually die and are cast off

Question 10

Bronchi

Answer 10

Pseudostratified Epithelium

• in fact a simple epithelium, peculiar arrangement of its cells gives a layered appearance

Question 11

Trachea

Answer 11

Ciliated Columnar Epithelium

• cells are columnar, supported by basement membrane
• has fine hair-like structure; ilia

Question 12

Urinary Bladder

Answer 12

Transitional Epithelium

• in an empty bladder, the superficial cells are low cuboidal or columnar
• when the bladder is full of urine, it will stretch over a fold, the cells exhibit a squamous appearance
• the cells of this epithelium have the ability to rearrange the number of cell layers depending it is distorted or contracted
• the cell show transition from one shape into another shape of epithelial cells

Question 13

found in air sacs of lungs and the lining of the heart, blood vessels, and lymphatic vessels

Answer 13

simple squamous

Question 14

lines the esophagus, mouth, and vagina

Answer 14

stratified squamous

Question 15

located in ducts and secretory portions of small glands and in kidney tubules

Answer 15

cuboidal

Question 16

ciliated tissues are in bronchi, uterine tubes, and uterus

Answer 16

columnar

Question 17

found in our respiratory tract and in the fallopian tubes women

Answer 17

ciliated epithelium

Question 18

ciliated tissues line the trachea and much of the upper respiratory

Answer 18

pseudostratified

Question 19

lines the bladder, urethra, and the ureters

Answer 19

transitional

Question 20

A type of tissue that lines certain internal organs and makes and releases substances in the body, such as mucous, digestive juices, and other fluids. Glandular tissue is commonly found in the breast, lung, stomach, colon, pancreas, prostate, uterus, and cervix. Also called glandular epithelium.

Question 21

A type of tissue that lines certain internal organs and makes and releases substances in the body, such as mucous, digestive juices, and other fluids. Glandular tissue is commonly found in the breast, lung, stomach, colon, pancreas, prostate, uterus, and cervix. Also called the glandular epithelium.

Answer 21

FAMILIARIZE

Question 22

Each cilium comprises nine pairs of microtubules that form the outside ring and two central microtubules. This structure is called an axoneme. The nine outer pairs are made up of motor proteins called dynein. These are large and flexible that allows the cilia to move.
