Immune System Defenses: Types and Processes
Nonspecific Defenses
The immune system employs various nonspecific defenses to protect the body from pathogens.
Phagocytes
Phagocytes are leukocytes responsible for removing microorganisms and foreign substances from tissues through phagocytosis.
Phagocytes move via amoeboid movements.
Types of Phagocytes
- Granulocytes: These cells contain abundant granules with enzymes and antimicrobial compounds.
- Monocytes: These cells lack granules and have a lobulated nucleus. They are larger than granulocytes.
Phagocytic

Soil Profile: Horizon A
Horizon washed or leached, dark tone. Poor, rich in mineral-humus soluble. 3 sublevels:
- A0: Raw humus-rich
- A1: Rich in humus
- A2: Predominant minerals on the humus
Horizon B
Precipitate dissolved salts of Horizon A tones. Shortage of organic richness of mineral salts.
Horizon C
Bedrock weathering process. Two sublevels:
- C1: Horizon Bedrock transition, more or less disintegrated
- C2: Horizon D or horizon R. The full Bedrock deeper.
Land Use
Each kind of soil is suitable for exploitation

Conflict Between Customary International Law and Domestic Law
As we have seen, the reception of customary international law into domestic law has been a major constraint.
