Respiratory System

Front 1

Functions of The Respiratory System

Back 1

1. Regulation of blood pH, the Respiratory system can alter blood pH by changing the blood CO2 levels.

2. Production of chemical mediators, the lungs produce an enzyme called angiotensin-converting enzyme (ACE), which is an important component of blood pressure regulation.

3. Voice Production, air moving past vocal folds make sound and speech possible.

4. Olfaction, the sense of smell occurs when airborne molecules are drawn into the nasal cavity.

5. Protection, the Respiratory system provides protection against some organisms by preventing them from entering the body and removing them from respiratory surfaces.

Hint 1

There are five functions

These are to do with, blood pH, chemical mediators, voice, smell, protection.

Front 2

Four processes of Respiration .

Back 2

1. Ventilation, the movement of air into the lungs.

2. Gas exchange, between air in the lungs and the blood sometimes called external respiration.

3. The transport of oxygen and CO2 in the blood

4. Gas exchange between the blood and the tissues sometimes called internal respiration.

Front 3

What is the largest part of the external nose?

Back 3

Haylaline Cartlidge Plates

Front 4

What does the bridge of the nose consistent of?

Back 4

Nasal bone, plus extensions of the maxillary and frontal bones

Front 5

Where does the nasal cavity start and finish?

Back 5

The nasal cavity extends from the NARIS or (nostril) to the opening of the pharynx or CHOANE

Front 6

What is the anterior part of the nares, what is this area lined with?

Back 6

Anterior part of the nares is vestibule, this area is lines with SQUAMOUS EPITHELUM

Front 7

The hard palate if formed by the .................... ..................... of the .................... and the palatine bone, it is covered by a highly vascular mucus membrane this forms the ............. .... ........... ............... ..................., and separates the naval cavity from the oral cavity

Back 7

The hard formed by the palatine process of the maxiale and the palatine bone, it is covered by a highly vascular mucus membrane this forms the floor of the nasal cavity and separates the naval cavity from the oral cavity

Front 8

The Nasal Septum separates the nasal cavity into the left and right sections. What forms the anterior and posterior parts of the nasal septum?

Back 8

Anterior side is made up Cartlidge. Posterior part consists of the vomer bone and the perpendicular plate of the ethmoid bone.

Front 9

What is a deviated septum?

Back 9

A deviated septum is where the septum bulges to one side

Front 10

Clinical Impact.

What is Sinusitis?

Back 10

The inflammation of the mucus membrane, this can occur in any part of a sinus. Causes include viral infections e.g. common colds, this causes the mucous membranes to become inflamed or swollen this causes the sinus opening to become blocked allowing mucous to accumulate within the sinus, this can cause bacterial infection.

Front 11

How can you treat Sinusitis?

Back 11

This can be achieved through antibiotics or promoting sinus grade with decongestants, hydration and steam inhalation.

There are three

Front 13

The five functions of the nasal cavity?

Back 13

1. Serves as a passageway for air, the nasal can't remains open even if the mouth is full of food.

2. Cleans the air, this is completed by the Vestibule which is lined with tiny hairs which trap large dust particles in the air.

3. Humidifies and warms the air , moisture Is created through mucous epithelium and from excess tears that drain into the nasal cavity, this adds moisture to the air that is then breathed in. Warm blood that is flowing through the mucous membrane then warms the air in the nasal cavity before it passes through the pharynx, this prevents damage to the rest of the Respiratory system that could be caused due to cold air.

4. Contains the Olfactory Epithelium, this is a sensory organ for smell and is located in the superior part of the nasal cavity.

5. Helps determine voice sound, the nasal cavity and paranasal sinuses are resonating chambers for speech.
