Passage of air into the lungs The trachea divides into two bronchi. One bronchus enters each lung. Each bronchus branches out into smaller tubes called bronchioles. Air travels through these bronchioles.

What is the structure and function of the respiratory system?

The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.

When you inhale through your nose or mouth, air travels down the pharynx (back of the throat), passes through your larynx (voice box) and into your trachea (windpipe). Your trachea is divided into 2 air passages called bronchial tubes. One bronchial tube leads to the left lung, the other to the right lung.

What is respiration BBC Bitesize ks3?

Respiration is a chemical reaction which occurs in all living cells, releasing energy from glucose. Aerobic respiration occurs with oxygen and releases more energy but more slowly. Anaerobic respiration occurs without oxygen and releases less energy but more quickly.

How does the respiratory system work ks2?

During the process of respiration, oxygen is taken in through the nose and/or mouth and then transported to the tissue cells via the bloodstream. A chemical reaction involving oxygen takes place inside the cells. Through this reaction, energy, carbon dioxide, and water are produced.

What are the 2 structural division of the respiratory system?

It has two major divisions: the upper respiratory tract and the lower respiratory tract . The upper respiratory tract includes the nasal cavity , pharynx , and larynx . All of these organs are involved in conduction, or the movement of air into and out of the body.
