Q

Electrolytes in plasma

A

Ca (muscle contraction), Fe, Na, K, Cl Mg, HCO3, PO4, SO4

Q

Serum of blood

A

When blood is removed from body and allowed to stand, it clots
Clots form solid coagulum

Serum= clear yellow liquid that separates from the coagulum (clot)
Serum on top and clot on bottom

SERUM IS PLASMA WITHOUT CLOTING FACTORS

16
Q

3 layers of serum:

A

Bottom layer: Erythrocytes (red cells)
Middle layer- buffy coat; WBC and platelets (,1%)
Upper layer- plasma (55% of blood)

17
Q

Erythrocytes

A 
Mature RBC
Most numbers
Red because of hemoglobin
Survives 120 days aka 3 months
Transports O2 from lungs to tissues and CO2 away from tissues
18
Q

Platelets or thrombocytes

A

Second numerous cells
Produced by fragmentations of cytoplasm of megkaryocytes (large) in bone marrow. Last 10-12 days
Role: homeostasis

19
Q

Leukocytes

A

Least numerous
WBC
Turnover quite fast bc live on for a few hours

20
Q

Types of Leukocytes

A

1) Neutrophils: Most numerous
8-10 hours in circulation
defense against bacterial or fungal infections
2) eosinophils
4-5 hours
defense against parasitic infection and dampen allergic response
3) basophils: mediate servere allergic reactions (anaphylactic) and inflammatory reactions

21
Q

Monocyte

A

10 hours in circlation
mature into macrophages
remove unwanted aged cells and other debris
Produce cytokines required for inflammatory and immune response

22
Q

Lymphocytes

A

Variabele lifespain

T, B, and natural killer cells

23
Q

Functions of blood

A

1) transport of nutrients and waste products
2) respiratory gas transport
3) thermoregulation
4) maintaining of homeostasis
5) homeostasis

24
Q

CBC

A

gives you info about # of cells

25
Q

Hematocrit (HCT)

A

amount of space (volume) RBCs take up in the blood

26
Q

Mean corpuscular (cell) volume (MCV)

A

RBC size

27
Q

Mean corpuscular cell hemoglobin (MCH)

A

Measure of RBC weight

28
Q

Mean corpuscular cell hemoglobin concentration (MCHC)

A

measure of how many RBCs in a certain amount of fluid

29
Q

Red cell distribution (RDW)

A

measure of size variations of RBCs

30
Q

Mean platelet volume

A

Measure of average amount of platelets

31
Q

Blood stains

A

Romanowsky stains:
Wright’s stain: siple
Giemsa stain: more complex, delicate staining characteristics and detection of blood parasites
May Grunwalk stain: good for routine word
