Cockroaches breathe through holes in their bodies called spiracles.

Cockroaches have tracheal respiratory systems. These systems consist of a network of tubes called tracheae that deliver oxygen directly to the cockroach's cells. This system allows cockroaches to efficiently exchange gases without the need for lungs.
1. Respiratory system 2. Cardiovascular system
The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe, we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system's means of getting oxygen to the blood.
In frogs, the respiratory system involves the exchange of gases through their moist skin and lungs. The circulatory system works to transport oxygen absorbed by the respiratory system to various tissues in the body and remove carbon dioxide. The two systems work together by ensuring that oxygen is delivered to the cells and carbon dioxide is removed efficiently.
Nose hair helps filter out dust, particles, and bacteria from entering the respiratory system, preventing respiratory infections. Removing nose hair can increase the risk of respiratory infections and allergies.
Your whole parasympathetic nervous system (the calming side of your nervous system) will be suppressed, while your sympathetic nervous system will be activated. Your digestive system will also be repressed, and, over time, your immune system could be repressed.
