The very first part of the respiratory tract are the openings into the nasal cavities called the nares.
The tonsils are the first lymphatic tissue that inspired air encounters as it passes through the mouth and nose. The tonsils help to trap and remove pathogens and foreign particles in the air as it enters the respiratory system.
The fact that it is a "system" dictates that it is part of the "respiratory system". But to answer the question I think you are asking I would have to say it works in conjunction with the cardio- pulmonary system in the absorption of oxygen.Respiration is the act of bringing oxygen into your body and exhaling carbon dioxide and other wastes from your body. This is done via the lungs or pulmonary system. Medicine was first organized in Latin but since this is a language no longer used, we have come up with our own terms as well, which is why we have different names for the same systems (circulatory/cardiac, pulmonary/respiratory, hepatic/liver, renal/kidneys, etc).
If you mean 'respiratory system'.....then it starts at the nose (breathing in is the first process before the air can reach the lungs for filtering out of oxygen into the blood stream). Breathing in is referred to as inhalation (of air), and breathing out is exhalation. Try browsing through the Biology categories (Human Anatomy, etc.) for the technical details, if you need them.
In an earthworm, nephridia occur in all body segments except the first three segments. Integumentary nephridia are V-shaped and lack nephrostomes.
Yes, the trachea is the first structure classified as a part of the lower respiratory tract.
The respiratory tract begins with the mouth or the nose, and then the pharynx, larynx, trachea, bronchus, bronchioles, and then the oxygen exchange occurs in the alveoli.
Materials travel through the body by first entering the bloodstream through absorption in the digestive system, inhalation in the respiratory system, or direct injection. They are then transported to target tissues and organs by the circulatory system. Once delivered, the materials can be used for various functions or eliminated from the body through excretion.

Respiratory System . ;)
your nose!
Yes, Invertebrates have respiratory system. upto phylum Annelida no special respiratory organs are found. The respiratory system first appears in phylum Arthropoda. Trachea, Book lungs, book gills are respiratory organs in Arthropodans. Mollusca have gills. Echinodermata have Tube feet, Respiratoryy tree and bursae
The respiratory system is composed of moist passageways that permit air to flow from the external environment to the lungs. In the lungs, blood vessels carrying CO2 on hemoglobin molecules releases the CO2 at the alveoli in exchange for O2. The CO2 is breathed out through the lungs, while the fresh O2 travels through the bloodstream to the cells in all parts of the body. (The first sentence is an extremely simplified and narrow description of the respiratory system, which is much more complicated.)
Yes it does, it is the respiratory system, meaning breathing system. :D
Yes, the nose is the first part of the respiratory system that cleans, moistens, and warms the air we breathe. It is lined with hair and mucus that trap particles, and blood vessels and mucous membranes that humidify and warm the air before it reaches the lungs.
nasal cavity
the first step in respiration is glycolysis.
it goes through the ndhuethy first and then the air goes through the ferstahjd and then the air comes out of the ear, breathing out carbon dioxide. This is the answer
