RESPIRATORY SYSTEM Flashcards
TERMS - DISEASES
WHAT DOES RESPIRATORY SYSTEM MEANS?
supplies the blood with oxygen for transportation to the cells in all parts of the body. Removes carbon dioxide and some water waste from the body
RESPIRATORY SYSTEM IS DIVIDED INTO?
upper respiratory tract
lower respiratory tract
WHAT CONSISTS UPPER RESPIRATORY TRACT?
Consists of the nose, mouth, pharynx, epiglottis, larynx, and trachea. Also called airways
WHAT CONSISTS LOWER RESPIRATORY TRACT?
Consist of the brochial tree and lungs. Also called airways
WHAT IS THE NASAL CAVITY?
the nose where air enters thru the nasal cavity to the body (the interior portion of the nose)
WHAT ARE THE NOSTRILS?
the external openings of the nose
WHAT IS THE NASAL SEPTUM?
is a wall of cartilage that divides the nose into two equal sections. The SEPTUM is a wall that separates the two chambers
WHAT IS CILIA?
the thin hairs located just inside the nostrils, it filters incoming air to remove debris.
WHAT IS MUCUOS MEMBRANES?
line the nose.
WHAT IS THE MUCUS?
is a slippery secretion produced by the mucuos membranes that protects and lubricates these tissues. In the nose mucus helps moisten, warm, and filter the air as it enters.
WHAT IS THE OLFACTORY RECEPTORS?
are nerve endings that act as the receptors for the sense of smell
WHAT ARE THE TONSILS?
the tonsils and adenoids are part of the lymphatic system. They help protection the body from infection coming through the nose of the mouth
WHAT IS THE PARANASAL SINUSES?
these are air filled cavities lined with mucous membrane, are located in the bones of the skull
PARA
near
NAS
nose
AL
pertaining to
FRONTAL SINUSES
located in the frontal bone just above the eyebrows
SPHENOID SINUSES
located in the sphenoid bone behind the eye. an infection here can damaged the vision
MAXILLARY SINUSES
which are the largest of the paranasal sinuses are located in the maxillary bones under the eyes
ETHMOID SINUSES
which is located in the ethmoid bones between the nose and the eyes
WHAT IS THE PHARYNX ALSO CALLED?
is called the THROAT receives the air after it passes through the nose or mouth as well as food
HOW MANY DIVISION ARE IN THE PHARYNX?
- Nasopharynx
- Oropharynx
- Laryngopharynx
Where is the NASOPHARYNX located?
is the first division located in the posterior to the nasal cavity and continues downward to behind the mouth
NAS/O
nose
PHARYNX
throat
Where is the OROPHARYNX located?
is the second division and is the portion that is visible when lookin into the mouth
OR/O
mouth
Where is the LARYNGOPHARYNX?
is the third division, is also shared by both the respiratory and digestive systems. Air, food, and fluids continue downward to the openings of the esophagus and trachea where air enters the trachea and food and fluids into the esophagus
LARYNG/O
larynx
WHAT IS THE LARYNX?
also known as the voice box is a triangular chamber located between the pharynx and the trachea
THYROID CARTILAGE
these are nine cartilages that protects the larynx. Is the largest projected from the front of the throat also called ADAM’S APPLE
VOCAL CORDS
the larynx contains the vocal cords. During breathing the cords are separated to let air pass
WHAT IS THE SOFT PALATE?
is the muscular posterior portion of the roof of the mouth, moves up and backward during swallowing to close off the nasopharynx. This prevents food or liquid from going up into the nose
WHAT IS THE EPIGLOTTIS?
is a lid-like structure located at the base of the tongue, swings downard and closes off the laryngopharynx so that does not enter the trachea and the lungs
WHAT IS THE TRACHEA?
the role of the trachea is to transport air to and from the lungs. this is also called WINDPIPE is loated directly in front of the esophagus
FUNCTION OF THE TRACHEA
the trachea is held open by aseries of flexibe C-shaped cartilage rings that make possible for the trachea to compress so that food can pass down the esophagus
WHAT IS THE BRONCHI?
are the two large tubes also known as PRIMARY BRONCHI which branch our from the trachea and convey air into the two lungs. This is referred to as the bronchial tree
DIVISION OF THE REPIRATORY PROCESS
The pharynx, the larynx, the trachea, the bronchi divides into two brochioles into the lungs, and leads into the ALVEOLI (air sacs) inside the lungs filled with many alveolus=singular
WHAT IS THE ALVEOLI?
also known as air sacs, are very small grape-like clusters found at the end of each brochiole where the exchange of gas takes place.
WHAT KIND OF GASES ARE EXCHANGE?
the exchange of oxygen and carbon dioxide between the air inside the alveoli and the blood int the pulmonary capillaries occurs through the thin, elastic walls of the alveoli
WHAT IS SURFACTANT?
reduces the surface tension of the fluid in the lungs
DEFIITION OF LUNGS?
The lungs which are the essential organs of respiration, are divided into lobes
WHAT IS A LOBE?
is a subdivision or part of an organ
WHAT IS IN THE RIGHT LUNG?
R lung is larger and has tree lobes the upper, middle, lower
WHAT IS IN THE LEFT LUNG?
it has only two lobes, upper and lower due to space restrictions because the heart is located on that side of the body
WHAT IS THE MEDIASTINUM?
is the middle section of the chest cavity and is located between the lungs.
WHAT IS THE PLEURA?
the pleura is a thin, moist and slippery membrane that covers the outer surface of the lungs
PARIETAL PLEURA
is the outer layer of the pleura It lines the walls of the thoracic cavity covers the diaphram and forms the sac containing each lung. The parietal is attached to the chest
PARIETAL
relating to the walls of a cavity
VISCERAL PLEURA
is the inners layer of the pleura that covers each lung
VISCERAL
relating to the internal organs
PLEURAL CAVITY
also known as the PLEURAL SPACE is a thin fluid filled space between the parietal and visceral pleural membrane
WHAT IS THE DIAPHRAGM?
is a dome-shaped sheet of muscle that separates the thoracic cavity from the abdomen. Its the contraction and relaxation of this muscle that makes breathing possible
WHAT IS THE PHRENIC NERVES?
stimulates the diaphragm and cause it to contract
WHAT IS RESPIRATION?
or breathing is the exchange of oxygen for carbon dioxide that is essential to life. VENTILATION is another word for moving air IN and OUT of the lungs
INHALATION
is the act of taking IN air as the diaphragm contracts and pulls downward
EXHALATION
is the act of breathing OUT. As the diaphragm relaxes it moves upward
EXTERNAL RESPIRATION
is the act of bringing air IN and OUT of the lungs from the outside environment and in the process exchanging oxygen fro carbon dioxide
INTERNAL RESPIRATION
is also known as CELLULAR REPIRATION is the exchange of gases within the cells of the blood and tissues
- OXYGEN passes from bloodstream into the CELLS
- CELLS give off the waste product (carbon dioxide)
- Bloodstream transports the CO2 to the lungs where is expelled during exhalation
