What are the organs of immune system?
It is in these organs where the cells of the immune system do their actual job of fighting off germs and foreign substances.
- Bone marrow. Bone marrow is a sponge-like tissue found inside the bones.
- Thymus. The thymus is located behind the breastbone above the heart.
- Lymph nodes.
- Spleen.
- Tonsils.
- Mucous membranes.
What are the 7 parts of the immune system?
The main parts of the immune system are: white blood cells, antibodies, the complement system, the lymphatic system, the spleen, the thymus, and the bone marrow.
What is immune system in Slideshare?
The immune system is composed of two major subdivisions, the innate or nonspecific immune system and the adaptive or specific immune system. The innate immune system is a primary defence mechanism against invading organisms, while the adaptive immune system acts as a second line of defence.
Which cell recognize and destroy tagged antigens and proliferate?
B cells
B cells: recognize antigens, proliferate and produce specific antibodies. proliferate, and produce specific antibodies.
What is the largest immune organ?
The spleen is the largest internal organ of the immune system, and as such, it contains a large number of immune system cells.
What is the immune system?
The immune system protects your child’s body from outside invaders, such as bacteria, viruses, fungi, and toxins (chemicals produced by microbes). It is made up of different organs, cells, and proteins that work together.
What are the cell of immune system?

The major proteins of the immune system are predominantly signaling proteins (often called cytokines), antibodies, and complement proteins.

How is the immune system split into two parts?
The immune system is split into two aspects, innate and adaptive InnateImmune Response Adaptive Immune Response Immune system Non-specific Distinguishes between human cells and pathogens But not between different types of pathogen Fast But no memory Highly specific Distinguishes between different pathogens
What does the immune system do for the body?
Let’s talk first about what the immune system does. The immune system is the body’s defense system. It is designed to protect against threats known as pathogens from outside the body such as fungi, bacteria, and viruses. This requires cellular machinery that allows the body to differentiate between foreign particles and “self.”
How does the immune system differentiate between different pathogens?
Immune Response Immune system Non-specific Distinguishes between human cells and pathogens But not between different types of pathogen Fast But no memory Highly specific Distinguishes between different pathogens based on shapes on the surface – called antigens Can take weeks But cells remember Describe innate immune system.
