The upper respiratory system includes the nostrils, nasal cavity, mouth, pharynx (throat) and larynx (voice box).
The lower respiratory system consists of the trachea and the bronchi, which divide into two to enter the right and left lungs. The trachea and bronchi are kept open by C-shaped rings of strong connective tissue (cartilage), making them semi-rigid tubes.
The lungs fill most of the chest cavity, which is separated from the abdomen by a large sheet of muscle, the diaphragm. Oxygen diffuses from the alveoli into the blood in the capillaries, while carbon dioxide diffuses from the blood to the alveoli.

Capillaries: Carry blood to the individual cells and tissues, very small and very low pressures.
Damaging an artery (and even a vein) can lead to severe blood loss if the bleeding is not controlled.


A severe bleed is a medical emergency which requires prompt first aid action in order to stop the bleeding and access emergency help.
Pressure: Ask the casualty to apply firm direct pressure over the wound (if the casualty is unable to do this, you will have to do it for them). If possible, you should avoid coming into direct contact with another person’s blood. Remember, the emphasis should be on applying and maintaining direct pressure over the wound as this will help stop significant blood loss. If there is an object in the wound (such as a piece of glass), then you should not remove it.
The following courses are presently being offered Fall, Spring and Summer terms unless otherwise noted.

If you suspect illness or injury, you should always seek immediate professional medical advice. It starts from the cavity at the back of the mouth and nose and extends to where it divides into two separate tubes, the trachea and the oesophagus.
It is in the front of the throat and begins at the larynx and vocal cords, extending down to the lungs. The two bronchi then divide into progressively smaller bronchi, bronchioles and, finally, alveoli (terminal air sacs). The lungs are spongy, elastic organs consisting of the bronchial tree, alveoli and blood vessels. Carbon dioxide is a waste product of metabolism (burning of the body’s energy systems) and is expelled as we breathe out.
It is an involuntary muscular action caused by contraction of the muscles that lifts the ribs while the diaphragm is pulled down and flattened.


When the muscles of inspiration relax, the elastic recoil of the lung tissues pushes air out of the lungs.
The average amount of air taken in one breath is about half a litre, and is called the tidal volume. It acts like a metronome (timing mechanism), sending out regular impulses that control the rate and depth of breathing (both inspiration and expiration).
Several infections can be carried in blood, and whilst the risk may be minimal you should always take precautions. Our body can cope with a small amount of blood loss (normally around a pint), this is why giving blood is perfectly safe.

The oesophagus is behind the trachea and carries food and liquids to the stomach (or back from the stomach to the throat during vomiting or regurgitation). The interface between those two structures is known as the respiratory membrane, and it allows the exchange (diffusion) of gases. The breathing control centre must have a good supply of oxygen, otherwise it will become damaged, fail to function properly and breathing will stop. It carries Oxygen to all the cells in our body and removes waste products such as Carbon Dioxide. Instead you should apply firm direct pressure around the wound, taking care not to move the object. If they go unconscious, you should check that they are still breathing and roll them onto their side.
