You're referring to the blood-brain barrier.
The outermost layer of skin, called the epidermis, protects the body from the external environment. It acts as a barrier against harmful substances, pathogens, and UV radiation.
The immune system helps protect the body from harmful invaders like viruses and bacteria by neutralizing and eliminating them. Skin acts as a physical barrier to prevent pathogens from entering the body. Antioxidants and other molecules help protect cells from damage caused by free radicals and other harmful substances.
White blood cells are a critical part of the body's immune system and help to defend against pathogens such as bacteria, viruses, and other harmful invaders. They work by identifying and destroying these pathogens through various mechanisms, including engulfing them, producing antibodies, and coordinating immune responses.
The immune system protects our body from harmful substances by identifying and combating pathogens such as viruses and bacteria. The excretory system removes wastes from cells through organs like the kidneys and liver, filtering out toxins and maintaining the body's internal balance.
Mucin plays several important functions in the body. It helps protect and lubricate the surfaces of the digestive, respiratory, and reproductive tracts. Mucin also helps trap pathogens and foreign particles, preventing them from entering the body.

A cell that protects the body by engulfing and digesting invading cells is called a phagocyte, such as macrophages and neutrophils. These cells play a crucial role in the immune system by detecting and eliminating pathogens and other harmful particles.
The skin is the primary tissue that protects the body from external pathogens, UV radiation, and physical damage. It acts as a barrier to prevent harmful substances from entering the body and helps regulate body temperature. Additionally, mucous membranes in various tissues provide protection by producing mucus to trap and expel pathogens.
