Active immunity

Vaccines, actually getting the infection

Pathogens

200825337_ — 2025-05-11 20:46:18 UTC

Micro organisms that cause disease

Cholera

200825337_ — 2025-05-11 20:47:51 UTC

It causes dehydration because water goes into small intestine by osmosis due to cholera's toxins getting many chlorine ions in small intestine lumen

Cellular defenses

Phagocytes

200825337_ — 2025-05-11 20:53:30 UTC

Lymphocytes

200825337_ — 2025-05-11 20:54:00 UTC

Phagocytosis

200825337_ — 2025-05-11 20:56:02 UTC

The phagocyte engulfs the pathogen by encircling it in its pseudopodia, and then making a vacuole, before diffusing enzymes into the vacuole to break down the pathogen and releasing anti toxins into it, and absorbing what's left

antibodies

200825337_ — 2025-05-11 20:56:48 UTC

agglutination and direct murder

200825337_ — 2025-05-11 21:02:24 UTC

Herd immunity

If a lot of people in a population has Active immunity, the disease has no one to transmit to.
