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.
What else can I help you with?
Through which part of the respiratory system does air travel first?
The very first part of the respiratory tract are the openings into the nasal cavities called the nares.
What two body systems does the pharynx belong to?
The pharynx belongs to both the respiratory system and the digestive system. It serves as a passageway for air to travel from the mouth and nose to the trachea and for food to travel from the mouth to the esophagus.
How does oxygen move the respiratory system to the circulatory system?
by diffusion across a capillary wall
What is the pathway for materials to travel?
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.
What is the maximum distance that respiratory droplets can travel through the air?
Respiratory droplets can travel up to 6 feet when emitted through coughing or sneezing. However, they can travel further with forceful exhalation or in poorly ventilated indoor spaces.
Both food and air travel through what?
Both food and air travel through the digestive system. Food travels through the digestive system starting from the mouth, passing through the esophagus and stomach, and finally to the small and large intestines for absorption. Air travels through the respiratory system starting from the nose or mouth, passing through the trachea and bronchial tubes, and finally reaching the lungs for oxygen exchange.
How is respiratory system and digestive system related to the circulatory system?
The respiratory system provides oxygen so the body can "burn" (oxidize) the food that is brought into the body through the digestive system. The circulatory system brings nourishment to all cells of the body. The circulatory system exchanges critical gases with the respiratory system; unneeded carbon dioxide is exchanged for much needed oxygen.
Why is carbon dioxide important to the respiratory system?
Carbon dioxide is a waste product produced by cells during cellular respiration. In the respiratory system, carbon dioxide is removed from the body by being exhaled out of the lungs. This helps maintain the body's acid-base balance and ensures that oxygen can be efficiently transported to cells.
Why does light travel more quickly through solids than through gasses?
Light generally doesn't travel faster through solids than through gases. Sound does, but not light.
Which system regulates the amount of water and mineral salts in the blood?
endocrine system, excretory system, digestive sytem, respiratory system, etc, This is because blood is the common carrier for all substances to be transported within the body.
Once oxygen enters your respiratory system how does it travel around your bodies?
It binds to red blood cells, which transport it to the tissues and organs.
Name the structures of the male reproductive system that sperm do not travel through?
The structures of the male reproductive system that sperm do not travel through include Cowpter's gland and the seminal vessel
