Adaptive (specific) Second Pus, swelling, redness, pain, T and B lymphocyte response

What is the 2nd line of defense immune system?

The second line of defense is nonspecific resistance that destroys invaders in a generalized way without targeting specific individuals: Phagocytic cells ingest and destroy all microbes that pass into body tissues. For example macrophages are cells derived from monocytes (a type of white blood cell).

What is the first line of defense example?

The first line of defence (or outside defence system) includes physical and chemical barriers that are always ready and prepared to defend the body from infection. These include your skin, tears, mucus, cilia, stomach acid, urine flow, ‘friendly’ bacteria and white blood cells called neutrophils.

What are the 3 different types of immunity?

Humans have three types of immunity — innate, adaptive, and passive:
  • Innate immunity: Everyone is born with innate (or natural) immunity, a type of general protection. …
  • Adaptive immunity: Adaptive (or active) immunity develops throughout our lives.

Macrophages. Macrophages are the body’s first line of defense and have many roles. A macrophage is the first cell to recognize and engulf foreign substances (antigens). Macrophages break down these substances and present the smaller proteins to the T lymphocytes.

What happens in the third line of defense?

The third line of defence is called the immune response and is SPECIFIC. It involves the production of two types of lymphocytes (B and T cells) which are specific to the invading particle. They work together to attack the pathogen.

Which of the following systems is the body’s first line of defense against infections?

The innate immune system is our body’s first line of defense against pathogens. It is a generalized, non-specific defense system (meaning that the defenses protect against all pathogens). The innate immune system defenses consist of the protective mechanisms we are born with (innate means “inborn” or “natural”).

What does the body second line of defense against pathogens consist of quizlet?

Inflammation, fever, phagocytosis, interferon, and complement are all part of the second line defenses.

What are the parts of the second line of defense?

In our bodies the second line of defense is non-specific immune responses – macrophages, neutrophils, interferons, and complement proteins. This line of defense also includes fever and inflammatory response as nonspecific defenses.

What are two categories of second line defenses?

  • Neutrophils (PMNs)
  • Eosinophils.
  • Basophils.
  • Mast Cells.
