Which of the following is not a type of lymphocyte?
A. B cells
B. T cells
C. Monocytes
D. Natural Killer cells

A

Monocytes

40
Q

What type of lymphocyte is responsible for producing antibodies?

A

B cells are responsible for producing antibodies.

41
Q

What is the role of T cells in the immune system?

A

T cells have several roles, including recognizing and destroying infected or cancerous cells, regulating the immune response, and assisting B cells in producing antibodies

42
Q

Which type of T cell is responsible for killing infected cells?
A. Helper T cells
B. Memory T cells
C. Cytotoxic T cells
D. Regulatory T cells

A

Cytotoxic T cells are responsible for killing infected cells.

43
Q

___________ cells are responsible for recognizing and destroying abnormal cells, such as infected or cancerous cells.

A

Natural killer cells

44
Q

What is the primary difference between B cells and T cells?

A

The primary difference between B cells and T cells is that B cells produce antibodies, while T cells do not. T cells are responsible for recognizing and destroying infected or cancerous cells, regulating the immune response, and assisting B cells in producing antibodies.

45
Q

What is the primary function of monocytes?

A

The primary function of monocytes is to phagocytose or engulf and destroy foreign substances, such as bacteria and viruses.

46
Q

What is the precursor cell of monocytes?
A. B cells
B. T cells
C. Neutrophils
D. Monoblasts

A

Monoblasts are the precursor cells of monocytes.

47
Q

What is the difference between monocytes and macrophages?

A

Monocytes are immature white blood cells that circulate in the bloodstream, while macrophages are mature monocytes that have left the bloodstream and reside in tissues throughout the body.

48
Q

What is the role of monocytes in the immune response?

A

Monocytes are one of the first cells to arrive at the site of infection or inflammation and are responsible for engulfing and destroying foreign substances.

49
Q

What is the function of macrophages?

A

Macrophages are responsible for engulfing and destroying foreign substances, as well as presenting antigens to other immune cells.

50
Q

Which of the following is a characteristic of monocytes?
A. They are the smallest type of white blood cell
B. They are responsible for producing antibodies
C. They have a long lifespan
D. They are able to migrate across blood vessel walls

Monocytes are able to migrate across blood vessel walls.

51
Q

What are platelets?

A

Platelets are small, colorless cell fragments that circulate in the blood and are involved in blood clotting.

52
Q

What is the primary function of platelets?

A

The primary function of platelets is to stop bleeding by forming blood clots.

53
Q

What is the process by which platelets form a blood clot?

A

When a blood vessel is damaged, platelets become activated and stick to the damaged area, forming a platelet plug. The platelets then release chemicals that stimulate further clotting and reinforce the plug.

54
Q

Thrombocytopenia is a condition characterized by a low platelet count in the blood, which can lead to an increased risk of bleeding. True or false?

A

True

55
Q

What is the normal range for platelet count in the blood?
A. 10,000-20,000 per microliter
B. 50,000-100,000 per microliter
C. 150,000-400,000 per microliter
D. 500,000-1,000,000 per microliter

A

The normal range for platelet count in the blood is 150,000-400,000 per microliter.

56
Q

What is the role of platelets in wound healing?

A

Platelets are involved in the initial stages of wound healing by forming a blood clot that stops bleeding and provides a scaffold for tissue repair.

57
Q

What is the first stage of blood clotting?

A

The first stage of blood clotting is the activation of platelets.

58
Q

______________ is the second stage of blood clotting.

A

coagulation cascade.

59
Q

Which of the following is a protein involved in the coagulation cascade?
A. Fibrinogen
B. Albumin
C. Globulin
D. Hemoglobin

A

Fibrinogen is a protein involved in the coagulation cascade.

60
Q

What is the final product of the coagulation cascade?
A. Fibrinogen
B. Fibrin
C. Platelets
D. Prothrombin

A

Fibrin

61
Q

What is the role of vitamin K in blood clotting?

A

Vitamin K is necessary for the production of several proteins involved in the coagulation cascade.

62
Q

The process by which a blood clot dissolves is called ______________

A

fibrinolysis.

63
Q

Which of the following is an enzyme involved in fibrinolysis?
A. Thrombin
B. Fibrinogen
C. Plasmin
D. Factor VIII

A

Plasmin is an enzyme involved in fibrinolysis.

64
Q

What is the role of anticoagulants in blood clotting?

A

Anticoagulants prevent blood clots from forming or help dissolve existing blood clots.

65
Q

What is a thrombus?

A

A thrombus is a blood clot that forms inside a blood vessel and can block blood flow.
