QuestionAnswer
What Structures distribute air Nose, Nasopharynx, Oropharynx, Laryngopharynx. Larynx NNOLL
Functions of the respiratory system Air distribution gas exchange Filters Air
Cribaform plate The roof of the nose is separated from the cranial cavity by a portion of the ethmoid bone
what are the small openings in the cribaform plate for many small openings that permit branches of the olfactory nerve responsible for the special sense of smell to enter the cranial cavity and reach the brain.
Names for the external openings to the nasal cavities Nostrils Anterior Nares External Nares
What is included in the upper respiratory tract Nose, Nasopharynx, Oropharynx, Laryngopharynx, Larynx
The sequence of air as it passes through the the nose into the pharynx Anterior nares, vestibule, inferior, middle, and superior meatus, posterior nares
Mucus membrane epithelium The nasal mucosa is a mucous membrane that has a pseudostratifed, cilated columnar epithelium rich in goblet cells
Paranasal sinuses are usually filled with AIR
What is the function of the Pharynx Common Pathway for the respiratory and digestive tract It also affects Phonation ( speech production)
Pharynx a tube like structure extending from the base of the skull to the esophagus
Where is olfactory epithelium found Nasal Mucosa plexus Ventilation
Standard atmospheric pressure 760 mmHG
Boyles law The volume of gas varies inversely with pressure at a constant temperature
When the pressure in lungs is greater than atmospheric pressure what occurs Expiration
Know the definition off vital capacity and how we determine The sum of IRV +TV+ERV-maximum volume of air that can be moved into and out of the lungs during forced respiration. It is determined by measuring the largest possible expiration after the largest possible inspiration
Know the definition of tidal volume Amount of air exhaled after normal inspiration
During inspiration what happens to the alveolar pressure. Does it increase or decrease Decrease because the lungs are inflated
If we have a excessive amount of fluid in the pleura cavity what would it cause Excess fluid in the pleural or abdominal cavities decreases vital capacity, as does the disease emphysema
What constitutes total lung volume Total lung Capacity (TLC) The sum of all four lung volumes- the total amount of air a lung can hold
The wall of GI tract is made up of four layers Serosa, Mucosa, Submucosa, Muscularis
Accessory organs Pancreas, Liver, Gallbladder
Biot's breathing Is characterized by repeated sequences of deep gasps and apnea. This type of abnormal breathing pattern is seen in individuals suffering from increased intracranial pressure
Know what will happen when we have a sudden rise in arterial blood pressure A sudden rise in arterial pressure by acting on aortic and carotid baroreceptors results in reflex slowing of respirations
Know what accessory organs of the digestive system are Salivary Glands, Tongue, Teeth, Vermiform Appendix, Pancreas, Liver, Gallbladder
what cell is found throughout most GI tract Columnar Epithelium
The hard palate consist of, The hard portions of four bones: Two maxillae, Two palatines
the small intestine consist of Duodenum, Jejunum, Lleum
Functions of the small intestines Food movement, Peristalsis, Major digestive organ, site of nutrient absorbtion into the blood, the longest portion of the GI tract
Extrinsic Muscles are important for deglutition (swallowing) and speech
Intrinsic Muscles are important for speech and mastication (chewing)
Organs of the upper tract are located outside the thorax
Accessory structures of the respiratory tract oral cavity, rib cage, and respiratory muscles including the diaphragm
Framework of the larynx is made up of nine cartilages
What is the largest cartilage of the larynx, and gives the characteristic triangular shape to its anterior wall The Thyroid Cartilage
The epiglottis is a small, leaf-shaped cartilage that projects upwards behind the tongue and hyoid bone
Intrinsic muscle both insert and originate within the Larynx
Extrinsic muscle insert in on the Larynx but originate on some other structure
Surfactant A component of the fluid coating the respiratory membrane that reduces surface tension
Alveoli Accomplish gas exchange
Left lung is divided into two lobes Superior and inferior
Right lung is divided into three tobes Superior, middle and inferior
Functions of the lungs Air distribution and gas exchange
Oblique Fisher Found in both lungs
Horizontal Fisher Only in right lung
Hard and soft Palate Suspend from he midpoint of the posterior border of the arch is the uvula
Tongue has three parts ROOT, TIP AND BODY
Filiform papillae do not contain taste buds
Esophagus Lined with stratified squamous epithelium
