Q

What is liquid plasma composed of

A

55% of whole blood in the average adult, and is 90 90 to 92% water, the remaining eight to 10% portion of plasma is dissolved substances, especially plasma proteins like albumin, globulin, and fibrinogen.

18
Q

What are globular?

A

Three main types, most commonly known gamma globulin -acts as antibody.

19
Q

What is fibrinogen?

A

Blood clotting protein.

20
Q

Dissolves in plasma for transport

A

Calcium, potassium, sodium, glucose, amino acids, fats, waste products like urea and creatine

21
Q

What are leukocytes?

A

Also known as white blood cells. Provides protection against invasion of pathogens such as bacteria, viruses, other foreign material. Spherical shape with a large nucleus about 8000 per cubic millimeter of blood

22
Q

How many types of white blood cells are there

A

There are five types each with its own strategy for protecting the body period can be subdivided into two categories. Granulocytes and agranulocytes.

23
Q

What are granulocytes?

A

With Granules in cytoplasm

24
Q

What are agranulocytes?

A

Without granules in cytoplasm.

25
Q

Granulocytes

A

Basophils, eosinophils, neutrophils

26
Q

What are basophils functions?

A

Release histamine and heparin to damaged tissues.

27
Q

What of the functions of eosinophils?

A

Destroys parasites and increase during allergic reactions.

28
Q

What is the function of a neutorphil?

A

Engulfs foreign material and damaged cells. (Phagocytosis. ) most numerous of leukocytes

29
Q

Agranulocytes

A

Monocytes and lymphocytes

30
Q

What are the functions of a monocyte?

A

Engulfs foreign material and damged cells (phagocytosis)

31
Q

What are the functions of lymphocytes?

A

Plays several different roles in immune response.

32
Q

Platelets

A

Also known as thrombocytes. Smallest of all the forms blood elements. Not Not whcells, formed when cytoplasm of a large precursor shatters into small plate like fragments. Between 200,000 to 300,000 per cubic millimeters in

33
Q

What is prothrombin?

A

Clottingg protein in blood

34
Q

What do platelets do?

A

Play critical part in blood clotting process, hemostasis. They clump together into small clusters when a blood vessel is damaged.

35
Q

what does a platelet do?

A

Releases a substance called thromboplastin, which in the presence of calcium reacts with prothrombin to form a rhombus, thrombin works to convert fibrinogen to fibrin which eventually becomes the mesh like blood clots

36
Q

Blood typing

A

Everyone’s blood is different due to the presence of antigens and markers on the surface of erythrocytes. Before a person receives a blood transfusion it is important to do blood typing.

37
Q

What is blood typing?

A

Lab tests to determine if donated blood is compatible with the recipient’s blood.

38
Q

although there are many subgroups of a blood markers, the two most important are?

A

Abo system and Rh factor

39
Q

Type A & B abo system

A

Two possible red blood cell markers, & B. A - marker in which cells identify themselves.

40
Q

A person with a markers is said to have what type of blood?

A

Type a blood

41
Q

Type A produces antib bodies so that

A

It will attack type B blood
