Animal respiratory systems are designed
to facilitate gas exchange
. In mammals, air is warmed and humidified in the nasal cavity. Air then travels down the pharynx and larynx, through the trachea, and into the lungs. In the lungs, air passes through the branching bronchi, reaching the respiratory bronchioles.
How does respiration work in animals?
When an animal breathes, it
takes in oxygen gas and releases carbon dioxide gas into the atmosphere
. This carbon dioxide is a waste product produced by the animal's cells during cellular respiration. Cellular respiration occurs in the individual cells. … Cells use oxygen to “burn” food for energy.
What is respiratory system in animals?
Respiratory system, the system in living organisms that
takes up oxygen and discharges carbon dioxide
in order to satisfy energy requirements. … With the exception of energy used by animal life in the deep ocean, all energy used by animals is ultimately derived from the energy of sunlight.
What is the main function of the respiratory system in animals?
Respiratory system, the system in living organisms that
takes up oxygen and discharges carbon dioxide in order to satisfy energy requirements
. In the living organism, energy is liberated, along with carbon dioxide, through the oxidation of molecules containing carbon.
How does the respiratory system work short answer?
The lungs and respiratory system
allow oxygen in the air to be taken into the body
, while also letting the body get rid of carbon dioxide in the air breathed out. When you breathe in, the diaphragm moves downward toward the abdomen, and the rib muscles pull the ribs upward and outward.
What are the 7 organs of respiratory system?
- Nose.
- Mouth.
- Throat (pharynx)
- Voice box (larynx)
- Windpipe (trachea)
- Large airways (bronchi)
- Small airways (bronchioles)
- Lungs.
What are the types of respiration in animals?
| Aerobic Respiration Anaerobic Respiration | 1. It takes place in the presence of oxygen. 1. It takes place in the absence of oxygen. | 2. Complete breakdown of food occurs. 2. Partial breakdown of food occurs. |

What is the most basic function of respiration?
The main function of the respiratory system is
the exchange of oxygen from the atmosphere for carbon dioxide produced by the cells of the body
.
What body parts do different animals use for breathing?
Skin, Gills, and Tracheal Systems
. Respiration can occur using a variety of respiratory organs
What controls the rate of breathing?
The respiratory rate is controlled by
the respiratory center located within the medulla oblongata in the brain
, which responds primarily to changes in carbon dioxide, oxygen, and pH levels in the blood. The normal respiratory rate of a child decreases from birth to adolescence.
Do lungs help blood get around your body?
Blood with fresh oxygen is carried from your lungs to the left side of your heart, which pumps blood around your body through the
arteries
. Blood without oxygen returns through the veins, to the right side of your heart.
What are the 5 main functions of the respiratory system?
- Gas Exchange – oxygen and carbon dioxide.
- Breathing – movement of air.
- Sound Production.
- Olfactory Assistance – sense of smell.
- Protection – from dust and microbes entering body through mucus production, cilia, and coughing.
What are the functions of lungs?
The main function of the lungs is
the process of gas exchange called respiration (or breathing)
. In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood. A reduced lung function means that the ability of lungs to exchange gases is reduced.
How many organs are in the respiratory system?
The respiratory system consists of
all the organs
involved in breathing. These include the nose, pharynx, larynx, trachea, bronchi and lungs.
How many parts does the respiratory system have?
There are
3
major parts of the respiratory system: the airway, the lungs, and the muscles of respiration. The airway, which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, carries air between the lungs and the body's exterior.
What are the 5 diseases of the respiratory system?
- Asthma. …
- Chronic Obstructive Pulmonary Disease (COPD) …
- Chronic Bronchitis. …
- Emphysema. …
- Lung Cancer. …
- Cystic Fibrosis/Bronchiectasis. …
- Pneumonia. …
- Pleural Effusion.
