Respiratory System Notes

Write the following notes in your journal.

Function: When we inhale, oxygen is brought into the lungs and taken to the body cells. When we exhale, the lungs contract and remove carbon dioxide and water vapor from the body. This is called breathing.Words to know:

1. Breathing – The movement of the chest that brings oxygen into the lungs and removes carbon dioxide from the body cells.

2. inhaling – bringing air into the lungs.

3. exhaling – pushing air out of the lungs.

4. respiration – the process that occurs in cells where glucose (food) is broken down to produce energy for the cell so the cell can do its job.

Cellular respiration

GLUCOSE + oxygen Carbon dioxide + water + ENERGY

Breathing process:1. Air is inhaled into lungs into air sacs (alveoli)2. Oxygen molecules move through the walls of the alveoli into the bloodstream. 3. Oxygen is taken by blood to all body cells.

4. Carbon dioxide (waste gas) moves out of the cell into the bloodstream.5. Blood carries the CO2 back to the lungs and it passes into the alveoli. 6. The alveoli contract pushing CO2 out of body.

Station 3

Vocabulary Definitions

Vocabulary – write the words and their definitions in your journal for this station.

Pharynx – a tubelike passageway used by food, liquid and air.

Larynx – the airway to which two pairs of horizontal folds of tissue called vocal chords are attached.

Trachea – a tube about 12 cm in length with strong C-shaped rings of cartilage that prevents the trachea from collapsing. It is also lined with mucus membranes and cilia.

Bronchi – two short tubes at the lower end of the trachea.

Alveoli – clusters of tiny, thin walled sacs at the end of each bronchiole that holds the air that we breathe.

Diaphragm – a muscle beneath your lungs that contracts and relaxes to help move gases into and out of your lungs.

Emphysema - a lung disease in which alveoli in the lungs enlarge.

Asthma – lung disorder in which the bronchial tubes contract quickly and cause shortness of breath, wheezing or coughing may occur as an allergic reaction.
