immune defense RETEACH RELEARN

Name the leukocyte

🦠 Function: First responder that eats bacteria (phagocytosis); quick to arrive and quick to die, has granules

🧠 Think: “Newbie fighter” – fast, messy, short-lived

The most common WBC

Neutrophil

Name the leukocyte:

🪱 Function: Fights parasites and handles allergic reactions, has granules

🧠 Think: “Eo = Ewww worm” or sniffles from allergies

Eosinophil

Name the leukocyte:

🎈 Function: Releases histamine during allergic reactions and inflammation, gas granules

🧠 Think: “Basophils = Balloon swelling” (like runny nose, itchy eyes)

Basophil

Name this lymphocyte:

💥 Function: Produces antibodies to tag invaders for destruction; memory B cells remember past infections

🧠 Think: “B = Bullet shooter” 🧬🔫

B cell

Name this lymphocyte:

Function: “The commander” – activates other immune cells, including B cells and cytotoxic T cells

🧠 Think: “Calls the shots” 🎯

Helper T Cell

Function: Kill infected cells, coordinate the immune response

• Think: “T = Tactical team”

  • Helper T cells (CD4) = call the shots, activate other cells

  • Cytotoxic T cells (CD8) = destroy infected or cancerous cells directly

T cells

Name the lymphocyte:

💣 Function: Destroys virus-infected and cancer cells

🧠 Think: “Tactical killer” – finds and attacks enemies inside the body

6. Cytotoxic T Cell (CD8)

Name the lymphocyte :

🥷 Function: Destroys virus-infected cells and tumor cells without needing activation

🧠 Think: “NK = No Kindness” — fast & silent assassin

Natural Killer (NK) Cell

Name this phagocyte:

🧹 Function: Big eater that digests invaders and cleans up dead cells; activates T cells by showing them invaders

🧠 Think: “Mac = Big Mac eater” 🍔

Macrophage

Name the phagocyte:

(Same as above – phagocyte version)

🦠 Function: First to fight by eating bacteria and dying soon after

🧠 Think: “Disposable soldier”

Neutrophil

🔬 Function: Group of WBCs with granules – includes neutrophils, eosinophils, and basophils

🧠 Think: “Grainy, grabby, go-go-go!”

Granulocyte

🧠 Function: WBCs without granules – includes lymphocytes and monocytes

🧠 Think: “Smooth & smart strategists”

Agranulocyte

Function: Lives in tissues like skin, captures invaders, and presents them to T cells to start an immune response

🧠 Think: “Immune snitch” — like a reporter that says “Hey! Look at this threat!”

Dendritic Cell

Name the Granulocytes (contain granules in their cytoplasm)

Neutrophils

Eosinophils

Basophils

Name the Agranulocytes (no granules)

Lymphocytes (includes B cells, T cells, NK cells)

Monocytes (turn into macrophages & dendritic cells)”

Name the Phagocytes (eat invaders through phagocytosis)

Neutrophils

Macrophages

Dendritic cells

Which cells are part of the Adaptive (Specific) Immune System?

🧠 Think: “They remember and adapt – like honor students 📚”

B Cells

T Cells (Helper T and Cytotoxic T)

Which cells are part of the Innate (Nonspecific) Immune System?

• 🧠 Think: “Born ready – no training needed 🔥”

Neutrophils, Eosinophils, Basophils, Macrophages, NK Cells, Dendritic Cells

Which cells produce Antibodies?

B Cells (specifically Plasma B Cells

Which cells kill virus-infected or cancer cells?

Cytotoxic T Cells

Natural Killer (NK) Cells

Which cells help regulate or coordinate other immune cells?

Helper T Cells (CD4)

Which cells release histamine during allergic reactions?

Basophils

Which cells respond to parasites?

Eosinophils
