Answer 7

Struture of red blood cell suits its main fuction of oxygen transport.

Question 8

WHAT RED BLOOD CELLS

Answer 8

they are filled with protein( hemoglobin), abbreviated Hb, which picks up and transport oxygen.

Question 9

Role of the RED BLOOD CELLS

Answer 9

pred blood cell pass through the lungs and pick up oxgen; oxgen binds to iron atoms in the Hb molecules

CAN ALSO CARRY C02 BACK TO LUNGS

Question 10

The defense and general housekeeping.
Search and destory infected,inflammed or damaged tissues.

Question 11

What is the amount of white blood cell in the body

Answer 11

small fraction of the whole blood

Question 12

what is the immue system prgrammed to do

Answer 12

they are prgrammed to destroy any cell that does not display the corrrect idenfity markers.

Question 13

what are antigens

Answer 13

they are molcule tha t are recogized as forgein by the immue system and trigger immue repsonse

UNLIKE RBC - THEY HAVE A NUCLUES ( DNA FINGERPRINTING )

Question 14

how long does platelet last

Answer 14

5-9 days

Question 15

what does platelet do

Answer 15

bits of cytoplams pinched off from large cells in the bone .

Question 16

does platelet relate to blood clotting

Answer 16

platelet functio in blood clotting. Clotting proteins are always present in out blood but are not active unless there is an injury

Question 17

what happen when injury occurs

Answer 17

clotting protein are activated and form long sticky thread that trap the platelets and form a clot

Question 18

how long does clotting last

Answer 18

Normal clotting time is from 3 -15 mintues, but clotting time is extremely indivdual and can be affected by certain diasease suach as hemophila and various medication including blood thinners.

Question 19

how does investigatoe use blood clotting

Answer 19

investigators use the state of blood clotting as a rough guide to estimate how much time has passed since the blood has shed

Question 20

what is the blood clotting timeline

Answer 20

• shiny gelatinous pool bleeding = less than a hour
• blood is separated into clot = severl hour had passed.

Question 21

how can you tell whether if the blood is clotting

Answer 21

blood first begins to clot it forms a dark shiny jelly like mass, with time the clot begins to contract and separate from the yellowish serum.

Question 22

what are the timeline of a blood pool

Answer 22

1) coagulation ( is the blood from dark to light red) t = 0 hour

2) gelatinous ( form a rim ) 1.5 hour

3) rimdessication ( rim is dry and blood is turning black ) . (t=4 hr)

4) center dessication (pool of blood is fully dried and reach center) t=9hr

Question 23

what is the blood droplet timeline

Answer 23

fresh drop = even drop

10 min = drying and form a ring around the outside

30 min = center of drop dries

60 - 120 min- ring is darken

Question 24

what is blood typing

Answer 24

si where blood cell have antigen that give us the blood types. these are protiens that identify that blood cell as “self” ( the immune system will attack any cell seen as non-self )

Question 25

what happened is two different blood is mixed

Answer 25

when blood from one person is mixed with another person of a different types, it will be attack by the immune system ( the immue system will attack anmd surround which is aggulatination)

Question 26

what is meant when it is said that “ the cells have agglutinated

Answer 26

is the clumping together in a suspension of anitgen-bearing cells, mircoorganism, or particles in the presence of specific antibodies

Question 27

types a form a defensive antibodies against

Answer 27

Type A contains antigen A and
forms defensive antibodies against
B

Question 28

types b form a defensive antibodies against

Answer 28

Type B contains antigen B and
forms defensive antibodies against
A

Question 29

type AB form a defensive antibodies against

Answer 29

Type AB contains antigens A and
B
– Type AB does not form defensive
antibodies against either A and B

Question 30

types O form a defensive antibodies against

Answer 30

Type O contains no A or B antigens but forms defensive antibodies against A and B

Question 31

RH + have what

Answer 31

Rh+ has the antigen; Rh- does not
- There are three blood typing antigens:
– A
– B
– Rh (+/-)

Question 32

who is the unverseal donor

Answer 32

So the universal donor is O- cause It has no antigens at all
and No agglutination

Question 33

who is the universal receiver

Answer 33

The universal receiver is AB+
– Has all three antigens so any
incoming blood is seen as “self”.
– No agglutination will occur

Question 34

is O an antigen

Answer 34

O is not an antigens
