A thin layer of ciliated epithelial cells
is not part of the respiratory membrane. Pseudostratified ciliated epithelium is found in the nasal mucosa, nasopharynx and trachea. The respiratory membrane is two cell layers thick (a layer of alveolar cells and a capillary wall), along with a basement membrane.
Which of the following are parts of the respiratory membrane?
- alveolar wall (type 1 and type 11 aveolar cells and alveolar macrophages.
- epithelial basement membrane-under the aveolar wall.
- Capillary basement membrane-fused to the epithelial basement membrane.
- Capillary epithelium.
Which of the following is not part of the respiratory membrane of the lungs?
A thin layer of ciliated epithelial cells
is not part of the respiratory membrane. Pseudostratified
Which of the following are part of the respiratory membrane quizlet?
The respiratory membrane includes the
alveolar epithelial cells as well as the pulmonary capillary endothelial cells and fused basal laminae between alveolar
and epithelial cells. The respiratory membrane is where gas exchange takes place.
What are the six layers of the respiratory membrane?
- the alveolar fluid.
- the simple squamous epithelium of the alveolus.
- the basement membrane of the alveolar epithelium.
- the interstitial space.
- the basement membrane of the capillary endothelium.
Which of the following is not part of the respiratory?
The a)
larynx
is not a part of the upper respiratory system. The respiratory system is commonly separated into the upper and lower respiratory systems, which include the following structures: Upper respiratory system: nose, nasal cavities and sinuses, mouth, and pharynx.
What is the respiratory membrane comprised of?
The membrane separating air within the alveoli from the blood within pulmonary capillaries. It consists of
the alveolar wall, the capillary wall, and their basement membranes
. The respiratory membrane is very thin (less than 0.5 mm).
What are the 10 parts of the respiratory system?
- Nose and nasal cavity.
- Sinuses.
- Mouth.
- Throat (pharynx)
- Voice box (larynx)
- Windpipe (trachea)
- Diaphragm.
- Lungs.
What are the 8 structures and organs of the respiratory system?
These include
the nose, pharynx, larynx, trachea, bronchi and lungs
. The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function.
What are the 2 divisions of respiratory system?
The respiratory tract is divided into two main parts:
the upper respiratory tract, consisting
of the nose, nasal cavity and the pharynx; and the lower respiratory tract, consisting of the larynx, trachea, bronchi and the lungs.
Where is the respiratory membrane located?
The respiratory membrane (Figure 10a) is the structure gasses
pass through to move between the alveoli in the lungs and the blood
. It is a very thin membrane comprised of alveolar wall, and a capillary wall.
What is the respiratory membrane and what is the role in ventilation?
The purpose of the respiratory system is
to perform gas exchange
. Pulmonary ventilation provides air to the alveoli for this gas exchange process. At the respiratory membrane, where the alveolar and capillary walls meet, gases move across the membranes, with oxygen entering the bloodstream and carbon dioxide exiting.
What force moves oxygen and carbon dioxide across the respiratory membrane quizlet?
What force moves oxygen and carbon dioxide across the respiratory membrane?
The partial pressure of the individual gases is used
as the force to drive the diffusion of gases across the respiratory membrane.
How many layers does the respiratory membrane have?
The
four layers
of the respiratory membrane are: The alveolar wall which is made up of type I and type II alveolar cells. The epithelial basement…
What two factors prevent the lungs from collapsing?
But two factors prevent the lungs from collapsing:
surfactant and the intrapleural pressure
. Surfactant is a surface-active lipoprotein complex formed by type II alveolar cells.
What is respiratory unit?
The alveoli (singular: alveolus)
are tiny hollow air sacs that comprise the basic unit of respiration.
