Question 6

Similar to hyaline cartilage except, matrix is impregnated with fibers, yellow in color

Answer 6

Elastic cartilage

Question 7

is an irregular, dense, fibrous tissue with thinly dispersed, encapsulated chondrocytes. No perichondrium, so it blends with adjacent connective tissue.

Answer 7

Fibrocartilage

Question 8

a major structural and supportive connective tissue of the body. It forms the rigid part of the bone organs that make up the skeletal system.

Answer 8

Osseous Tissue

Question 9

are formations characteristic of mature bone and take shape during the process of bone remodeling, or renewal

Answer 9

Osteons

fluid that transports oxygen and nutrients to the cells and carries away carbon dioxide and other waste products

Answer 10

Blood

Question 11

is a yellowish liquid component of blood that holds the blood cells in whole blood in suspension

Answer 11

Blood plasma

Question 12

Known for their bright red color, red cells are the most abundant cell in the blood,

Answer 12

The Erythrocytes

Question 13

They are the cells of the immune system involved in defending the body against both infectious disease and foreign materials

Answer 13

Leukocytes or White Blood Cells

Question 14

Extracellular matrix of cartilage is mainly?

Answer 14

Collagen and/or elastic fibers, proteoglycans, and water.

Question 15

Cartilage is composed of specialized cells that produce a large amount of collagenous extracellular matrix, abundant ground substance that is rich in proteoglycan and elastin fibers.

Answer 15

Chondrocytes

Question 16

classification of cartilage

Answer 16

hyaline cartilage, elastic cartilage and fibrocartilage.

Question 17

This sort of growth of cartilage the extracellular matrix is secreted into spaces between the cells.

Answer 17

interstitial growth

Question 18

This growth is a layer of chondroblasts can lay down matrix at the outer edge of a mass of cartilage.

Answer 18

appositional

Question 19

is a major structural and supportive connective tissue of the body. It forms the rigid part of the bone organs that make up the skeletal system.

Answer 19

Osseous tissue

Question 20

Functions of Osseous Tissue

Answer 20

1.Support for muscles, organs, and soft tissues
2.Leverage and movement
3.Protection of vital organs, e. g. heart
4.Calcium phosphate storage
5.Hemopoiesis or the formation of blood cells

Question 21

is the fundamental functional unit of compact bone

Answer 21

The osteon or Haversian system

Question 22

is a connective tissue that has a fluid matrix, and no fibers.

Answer 22

blood

Question 23

fluid that transports oxygen and nutrients to the cells and carries away carbon dioxide and other waste products.

Answer 23

blood

Question 24

is a yellowish liquid component of blood that holds the blood cells in whole blood in suspension.

Answer 24

The Blood Plasma

Question 25

Plasma's total blood volume?

Answer 25

55%

Question 26

serves as a transport medium for delivering nutrients to the cells of the various organs of the body and for transporting waste products derived from cellular metabolism to the kidneys, liver, and lungs for excretion.

Answer 26

Plasma

Question 27

is blood plasma without clotting factors

Answer 27

blood serum

Question 28

Known for their bright red color, these cells are the most abundant cell in the blood, accounting for about 40 to 45 percent of its volume.

Answer 28

Erythrocytes

Question 29

Production of red blood cells is controlled by hormone produced primarily by the kidneys.

Answer 29

erythropoietin

Question 30

The red blood cell survives on average only ____ days.

Answer 30

120 days

Question 31

Special protein in blood that helps carry oxygen from the lungs to the rest of the body and then returns carbon dioxide from the body to the lungs so it can be exhaled

Answer 31

hemoglobin

Question 32

Erythrocytes are efficient transporters of gases because of the following histological features:

Answer 32

1. Biconcave form gives 20% - 30% greater surface area than the spherical form. 2. Absence of nucleus allows more spaces for gases. 3. Round edges and resilient elastic structure protects the erythrocytes from injury and allow them to bend at bifurcations in capillaries.

Question 33

are cell fragments which circulate within the blood

Answer 33

Thrombocytes or Platelets

Question 34

Life span of platelets

Answer 34

10 days
