AP Biology Immune System

What is the role of the immune system?

• To pump blood throughout the body

• To protect the body from disease-causing agents

• To contain disease-causing organisms to a single area of the body

• To give Mr. Elwonger something to test us over

The acquired immune system is...

• Always working to protect the body and doesn't require special preparation

• Needs to be "primed" before it can work to its full effectiveness

• Ineffective at protecting the body

• Only gained through artificial means, such as vaccinations.

Which of these is an example of acquired immunity? (TWO correct answers, select both)

• Macrophages

• T-Cells

• Antibodies

• Antigens

What is the role of antibodies in the immune system?

• To actively destroy pathogens

• To mark pathogens that need to be destroyed by T-cells

• To safeguard the body against being destroyed by its own immune system

• To bind to B-cells, helping them in their support of T-cells

What is the first line of defense your body has against pathogens?

• B-lymphocytes

• Antibodies

• Antigens

• Skin and mucus

Vaccinations work by...

• Strengthening the immune system by chemically changing B-cells

• Tricking the body into thinking the needle is a pathogen

• Injecting dead or weakened bacteria or viruses (or proteins from them) into the bloodstream to trigger the production of antibodies

• Vaccines don't work and are just the government's way of injecting microchips into the population so they can keep track of us.

What are the two groups of the immune system?

• Acquired and Innate

• Acquired and Learned

• External and internal

• Complex and simple

The innate immune system is...

• Always working and doesn't require any special preparation

• Needs to be "primed" before it can work to its full effectiveness

• Very specific and only defends against a specific pathogen

• Not very effective at preventing intruders

True or false: The lymphatic vessels are directly connected to the blood vessels

• True

• False

Which organ filters foreign material from the blood?

• Stomach

• Thymus gland

• Spleen

• Heart
