Respiratory System

Use the notes, slides and videos to learn about the respiratory system.

Open Ended

What is the difference between RESPIRATION and BREATHING.

RESPIRATION vs BREATHING

• Breathing is a biophysical process that involves the exchange of gases through inhalation and exhalation

• Respiration is a biochemical process to release energy from organic compounds which are then used for performing different physical activities.

Structure of the human respiratory system

• Pharynx- is part of the conducting zone for air into the lungs.Main function is to warm and humidify air before it reaches the lungs.

  
  

• Larynx- to protect the airway from choking on material in the throat. To regulate the flow of air into our lungs The production of sounds used for speech.

Structure of the human respiratory system

• Trachea- also called the windpipe, cartilaginous tube that connects the larynx  to the bronchi of the lungs

• Bronchi- the airways that lead from the trachea into the lungs

Structure of the human respiratory system

• Alveoli- where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out. also called as air sac.

• Diaphragm- located below the lungs, is the major muscle of respiration.

Multiple Choice

the airways that lead from the trachea into the lungs

• Trachea

• Bronchi

• Larynx

• Pharynx

Multiple Choice

It is also called an air sac.

• Alveoli

• Bronchi

• Larynx

• Pharynx

Multiple Choice

It is also called as the voicebox

• Larynx

• Pharynx

• Bronchi

• Alveoli

Multiple Choice

It is also called as your windpipe.

• Larynx

• Lung

• trachea

• Bronchi

Definition of terms:

• Respiration: a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.

• Gas exchange: It  is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs.

• Diffusion: the process of a substance spreading out to evenly fill its container or environment.

Multiple Choice

It is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs.

• Gas Exchange

• Diffusion

We now know that…

• Respiratory system includes trachea, bronchi, lungs, diaphragm, and the muscles between the ribs.

• Gas exchange is the diffusion of gases into and out of the body

• Oxygen diffuses from the air sacs into the blood. Carbon dioxide diffuses the other way. 

• Thin walls of air sacs help gas exchange to take place quickly.

Lesson objective

To learn about organs that make up human nervous system.

Nervous system

• The nervous system is the major controlling, regulatory, and communicating system in the body. It is the center of all mental activity including thought, learning, and memory.

Nervous System is made up of:

• Brain

• Spinal cord

• Nerves

• Sensory organs

How does the brain send messages to the body?

The brain is the body's control centre: it sends messages to your body through a network of nerves called “the nervous system”, which controls your muscles, so that you can walk, run and move around. The nervous system extends through your body from your spinal cord, which runs from your brain down your backbone.

Multiple Choice

Brain cells are called

• hemoglobin
• neurons
• brainpoppers
• alveoli

Multiple Choice

What is the function of the nervous system.

• provide nutrients for the body.
• send and recieve messages
• circulate oxygen to sells
• remove carbon dioxide from blood
