Gas Exchange
The respiratory system's job is to brings in gas that the body needs, like oxygen and to expel (or get rid of) gaseous waste your body doesn't need, like carbon dioxide and water vapor.

The respiratory system is in charge of gas exchange in the body.
What is Gas Exchange?
What is Gas Exchange?
Our body needs oxygen (O) to survive. Oxygen is a key ingredient our body needs to make energy. Oxygen is brought into the lungs from your mouth or nose. Next, oxygen moves from your lungs to your blood.
The circulatory system moves oxygen on red blood cells. Imagine that oxygen is a passenger and a red blood cell is a car. Then, red blood cells carry the oxygen to the entire body. The cells in your body use oxygen to help make energy.
Another function of the the respiratory system getting rid of gaseous waste, like carbon dioxide and water vapor. Carbon dioxide is moved from your cells to your lungs through your blood. Then carbon dioxide moves into your lungs and out your nose or mouth into the environment.
While you have lungs, fish have gills that serve as the location for gas exchange. Whatever animal you study, oxygen is taken in and carbon dioxide let out.
Interactions with Other Systems
Interactions with Other Systems
1. Respiratory System and the Skeleton
Without the skeletal system, the upper respiratory tract would have no structure at all and would be nothing but soft tissues. There is a long perpendicular plate that is on the ethmoid, which helps to keep the nasal cavity into two sides. This plate is what creates the septum in the nasal passageways.
If the respiratory system doesn't interact with the laryngeal skeleton, you wouldn't be able to speak. The laryngeal skeleton, the cartilage that can be found in the throat, is considered the real vocal cords which let you speak. As the air passes over the vocal cords, they begin to vibrate and create sound. It is the resonance of the throat, along with the sinuses and the thickness of the vocal cords, which create a unique voice for each person.
2. Respiratory System and Circulatory System
The circulatory system works well with the respiratory system to make sure that oxygen-rich blood can flow through your body. That is, your respiratory system supports your circulatory system with air or more specially oxygen which is sent to relative organs via arteries. Then the veins carry the deoxygenated blood to the heart, so it can be replenished.
3. Respiratory System and Digestive System
The respiratory system works with the digestive system as the digestive tract uses contractions from muscles to break down the food and move it through the tract. The digestive system transforms foods into energy to aid our bodily activities. Your respiratory system needs the digestive tract to keep working because the muscles of the respiratory system require fuel to work and they receive that from the digestive system.
4. Respiratory System and Nervous System
The lungs have receptors and sensors that react to deflation, inflation and chemical stimulation. This can ultimately activate the nervous system, resulting in a neutrally controlled response, like a sudden cough or an altered breathing pattern.

Hey Kids, have you ever wondered what happens after we breathe? How does the air travel inside our body? Well, Dr. Binocs is here to explain it all in today's topic, Respiratory System.
Oxygen’s surprisingly complex journey through your body
Oxygen’s surprisingly complex journey through your body
Oxygen forms about 21% of the air around us. In your body, oxygen forms a vital role in the production of energy in most cells. But if gases can only efficiently diffuse across tiny distances, how does oxygen reach the cells deep inside your body? Enda Butler tracks the surprisingly complex journey of oxygen through your body.
