What are the 7 functions of the respiratory system?

The functions of the respiratory system include gas exchange, acid-base balance, phonation, pulmonary defense and metabolism, and the handling of bioactive materials.

What are 5 examples of functions of the respiratory system?

There are five 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 9 functions of respiratory system?

9: The Respiratory System

• 9.1: Prelude to the Respiratory System. The air contains oxygen that crosses the lung tissue, enters the bloodstream, and travels to organs and tissues.
• 9.2: Systems of Gas Exchange.
• 9.3: Gas Exchange across Respiratory Surfaces.
• 9.4: Breathing.
• 9.5: Transport of Gases in Human Bodily Fluids.

What are the main function of the respiratory system?

Your lungs are part of the respiratory system, a group of organs and tissues that work together to help you breathe. The respiratory system’s main job is to move fresh air into your body while removing waste gases.

What are the major organs of the respiratory system and their functions?

These include the nose, pharynx, larynx, trachea, bronchi and lungs. The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function.

What are the parts of the lungs?

Lungs. Bronchial tubes/bronchi. Bronchioles. Air sacs (alveoli)

What are four functions of the respiratory system?

What does the respiratory system do?

• Allows you to talk and to smell.
• Warms air to match your body temperature and moisturizes it to the humidity level your body needs.
• Delivers oxygen to the cells in your body.
• Removes waste gases, including carbon dioxide, from the body when you exhale.

What are the 10 parts of the respiratory system?

These are the parts:

• Nose.
• Mouth.
• Throat (pharynx)
• Voice box (larynx)
• Windpipe (trachea)
• Large airways (bronchi)
• Small airways (bronchioles)
• Lungs.

What is the 9 parts of respiratory system?

Voice box (larynx) Windpipe (trachea) Airways (bronchi) Lungs.

What is the structure and function of the lungs?

The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic.

What are the two main organs of the respiratory system?

Pharynx (throat): Tube that delivers air from your mouth and nose to the trachea (windpipe). Trachea: Passage connecting your throat and lungs. Bronchial tubes: Tubes at the bottom of your windpipe that connect into each lung. Lungs: Two organs that remove oxygen from the air and pass it into your blood.

How many parts are in the lungs?

This sac also divides each lung into sections called lobes. The right lung has three lobes and the left has two. The lobes are further divided into bronchopulmonary segments and pulmonary lobules….Lung.
