Q

what is the role of blood clots

A
  • when you cut yourself, platelets forms a blood clots
  • the blood clot eventually hardens to form a scab that keep the wound clem and stop blood flow from bleeding out while new replacement skin grows

Q

plasma definition (2)

A
  • the pale yellow fluid of the blood where cells are suspended

Q

biconcave

  • definition
  • the purpose to the biconcave shape (2)
A
  • definition
  • the shape of RBC where cells are flat but dip inwards at the centre on both bottom and top
  • the purpose to the biconcave shape (2)
    1) allows them to slide throughout eh blood vessels with ease
    2) provides a large SA to volume ratio for an efficient gas exchange

Q

hemoglobin (2)

A
  • an iron containing pigment that binds O2 to facilitate its movement in the circulatory system
  • picks up O2
22
Q

what give the RBC and the whole blood sample their colour

A

hemoglobin

23
Q

oxyhemoglobin

A
  • a hemoglobin bound with O2 that has a “bright red colour:
24
Q

what is the colour of a oxygenated blood…and what gives it its colour

A
  • red

- oxyhemoglobin

25
Q

how RBC picks up and releases O2

A

1) as RBC through the (R) and (L) lungs
> hemoglobin picks up O2 to form oxyhemglobin = become a oxygenated blood and gains its bright colour

2) O2 rich blood enters the capillaries within the body
> oxyhemoglobin splits to release O2 to the cells and oxyhemoglobin turns into hemoglobin = blood becomes O2 poor then loses it bright colour

26
Q

if blood contains oxyhemoglobin or if the blood is bright red…it means the blood is …

A

oxygenated

27
Q

if blood contains hemoglobin it means the blood is and NOT oxyhemoglobin the blood is…

A

de-oxygenated

28
Q

WBC (3)

A
  • also called “leukocytes”
  • much larger in size than RBC
  • much lower in number than RBC
29
Q

WBC are proceeded where…

A

bone marrow

30
Q

what happens when WBC matures and is released from the bone marrow (3)

A
  • WBC keeps their nucleus
  • their shape is not uniform (their shape isn’t the same)
  • lack colour pigment -has no colour=white-
31
Q

WBC life span

A

much lesser than RBC

32
Q

how WBC reacts during when a disease-causing agents enter the body (1)

A
  • WBC “increase” in there number by…
    > releasing the stored WBC from the body
    > producing more int he bone marrow
33
Q

an “increase” of the WBC count indicate

A

an infection signal or a disease-causing agent has entered the body

34
Q

what seals a blood vessel when you’ve cut yourself..

A
  • protein

- proteins int he blood forms a plug that seals the damaged blood vessels. The plug that forms is called “Fibrinogen”

35
Q

Fibrinogen

  • definition
  • what activates fibrinogen
  • what happen to fibrinogen when it is activates
A
  • definition
    > - a “soluble protein” present int eh blood plasma
  • what activates fibrinogen
    > platelets
  • what happen to fibrinogen when it is activates
    > it converts to Fibrin
36
Q

THE CLOTTING PROCESS…

(4)…

A

look at you’re notes

37
Q

what causes platelets to rupture

A

when they come into contact with a rough surface

38
Q

what happens when the platelets rupture

A

it will trigger a complex series of chemical reactions hat causes the dissolved Fibrinogen intuits active form called Fibrin

39
Q

what is the active from of Fibrinogen

A

fibrin

40
Q

scab is formed from what

A

blood clot

41
Q

blood clot definition

A

a jelly-like, solid mass consisting mainly a RBC trapped in a knot to Fibrin

42
Q

Fibrin

A

a thread like “insoluble protein” formed from the Fibrinogen

43
Q

blood clot that is NOT life threatening is during…

A

when blood clot forms OUTSIDE the blood vessel

44
Q

life threatening blot clots is when.. (2)

A
  • blood clot is formed WITHIN the blood vessels

- happens during when walls of arteries becomes rough due to high fat diet

45
Q

HEMOPHILIA

  • definition (2)
  • consequence (2)
  • solution to hemophilia
A
  • definition
    > a blood disorder involving the bloods ability to clot, which can lead to excessive bleeding
    > lacking the ability to produce blood proteins (fibrinogen and fibrin) that allow platelets to form a clot
  • consequence (2)
    > excessive bleeding
    > longer time to heal
  • solution to hemophilia
    > transfusion of protein clotting factors and platelets
46
Q

PLASMA

  • 3 descriptions
  • what plasma holds and transports
A
  • 3 descriptions
    > yellowish liquid
    > mostly H2O with substances dissolved or suspended in it
    > more than half of the blood is composed of plasma
  • what plasma holds and transports
  • cells of the blood : RBC, WBC, platelets
  • dissolved CO2
  • urea
  • hormones
  • digested nutrients -from food you ate-
  • proteins such as…- fibrinogen and fibrin -
47
Q

what are the cells of the blood

A

RBC, WBC, platelets

48
Q

when a person loses a lot of blood… what does it need

A

plasma to restore and replace the lost liquids

49
Q

typical human has how much blood

A

5L

50
Q

blood consist of…

A

living AND non-living components

51
Q

hemoglobin allows RBC to…

A

pick up, carry, and transport O2 to the body cells

52
Q

platelets sole job

A
  • allows damaged blood vessels to repair and repents blood loss by forming blood clot
