Study Notes
Portal of Entry
- Organisms can enter the body via similar routes as they exit, such as body openings and breaches in skin or mucous membranes.
- Needle punctures serve as an example of how organisms gain entry, allowing more pathogens to enter while the device is attached.
- In cases of urinary catheters, obstructions in urine flow can facilitate the ascent of organisms up the urethra.
- Compromised body defenses significantly increase the likelihood of pathogen entrance, highlighting the importance of maintaining immune function.
