Centrifugation separates samples by

What is the term for the layer composed of wbc and platelets?

The formation of rbc is called?

RBC are also called

Types of cells in the blood that causes blood clots to form

The fluid in which other parts of the blood are suspended

The oxygen-carrying protein in blood

A universal donor

Can donate red blood cells to only AB but can receive from all others.

Can donate red blood cells to only A & AB

Any organism that causes disease like a virus or bacteria is called:

Any organism that causes disease like a virus or bacteria is called:

Part of the body's defense against pathogens in which cells of the immune system react to each kind of pathogen with a defense targeted specifically at that pathogen is called:

A molecule that the immune system recognizes either as part of the body or as coming from outside the body:

A protein produced by B cells of the immune system that destroys pathogens is called:

The body's ability to destroy pathogens before they can cause disease is called:

Which of the following is a way to spread infectious diseases?

What is the molecule located on the outside of a pathogen that the immune system recognizes?

What attaches to antigens and tags the pathogen for destruction?

Foreign cells in the body carry foreign proteins that the body recognises as 'non-self'. These are called:

When the body encounters a pathogen, antibodies are created that are specific to that pathogen. The next time the body encounters the pathogen, the response will be:

The diagram shows a pathogen, what is the arrow pointing to on the surface of the pathogen?

What is a preparation of dead or weakened pathogens that is introduced into the body to cause an immune response?

What function do memory cells have in our body?

Which of the following statements is NOT true about antigens?

What are the 4 types of pathogens that could cause illness?

The response to an infection. Causes the area to redden, swell, and feel warm.

Chemical that causes the blood vessels around the infection to dilate (expand) so that more blood can flow to the infection

What is phagocytosis?

The innate immune system is...

This sticky fluid traps any pathogens that try and get in our body

Cells that provide a physical barrier to resist pathogen invasion, as well as secrete protective substances to discourage the accumulation of pathogens.

This type of immunity can be called nonspecific and refers to the bodies defenses that are present since birth.

This type of immunity is acquired during one's lifetime. It is induced by antigens that invade the body.

These are proteins produced by the body's immune system specific to a foreign substance. These are sometimes called immunoglobulins which are produced by B-cells

programmed cell death, phagocytes will dispose of the fragments

This Immunoglobulin can trigger histamine to be released from mast cells when it binds to an antigen, It causes an alergic response. It also protects against parasitic worms

A(n) ________ is a substance that causes an immune response. It can be on the surface of a(n) pathogen.

_________ form in the bone marrow and mature in the thymus gland.

_________ form and mature in the bone marrow.

If the body produces antibodies in response to an antigen, this is called _________.

_________ is the introduction of antibodies that were produced outside the body.

These two types of antibodies protect the new born baby

This type of immunity can be called nonspecific and refers to the bodies defenses that are present since birth.

This type of immunity is acquired during one's lifetime. It is induced by antigens that invade the body.

A part of the innate immunity. The bodies defensive response caused by microbial infection, physical damage or chemical agents.
