What else can I help you with?
What produces surfactant?
Surfactant is produced by the type II alveolar cells in the lungs. These cells secrete surfactant which helps lower surface tension in the alveoli, preventing collapse and facilitating gas exchange.
In which layer of the alveolar membrane are the cleanup cells located?
The cleanup cells, also known as alveolar macrophages, are located in the alveolar space within the alveolar membrane. They play a crucial role in clearing debris, bacteria, and other particles from the lungs to maintain respiratory health.
Hypoventilation dramatically increases carbonic acid concentration and involves?
Hypoventilation leads to increased carbon dioxide levels in the blood, resulting in the production of carbonic acid, which lowers blood pH. This can lead to respiratory acidosis, where the body's pH is too acidic. Symptoms may include confusion, fatigue, and eventually respiratory failure if not corrected.
Describe the structure of a terminal bronchiole and its alveolar sac?
terminal brobchiole is formed as a result of division of respiratory bronchiole. It is extremely thin and end up into alveolar sac ALVEOLAR SAC THESE ARE SMALL SACS WITH 8 TO 10 SACCULES CALLES ALVEOLI. IT HAS CENTRAL AIR PASSAGE. THESE ALVEOLI SERVE AS RESPIRATORY MEMBRANE AND HELP IN EXCHANGE OF GASES
How does respiration rate and depth adjust to counteract hypoventilation?
When hypoventilation occurs, the body increases both the rate and depth of respiration to try to bring more oxygen into the lungs and remove excess carbon dioxide. This helps to correct the imbalance in blood oxygen and carbon dioxide levels by increasing the amount of gas exchange in the lungs. The increased respiration rate and depth help to improve oxygen levels in the blood and remove carbon dioxide to restore a more balanced state.
What is the disease CCHS?
Congenital central hypoventilation syndrome (CCHS) (formerly known as the Ondine curse, after the mythical story) is a disorder of the automatic control of breathing. In CCHS, the body "forgets" to breathe, especially during sleep. Researchers have identified a particular gene defect (PHOX2B) associated with congenital central hypoventilation syndrome, but how the mutation causes the syndrome is not yet known. It is also not known how frequently CCHS occurs, but it is estimated to be a rare disorder.
What does cchs stand for and what does it mean?
CCHS stands for Congenital Central Hypoventilation. CCHS is a disease or syndrome that affects a persons breathing ability and cause carbon dioxide to build up in the blood.
What is central pain syndrome?
Central pain syndrome is a type of pain that occurs because of injuries to the brain or spinal cord.
What is a respiratory rate that is higher than normal called?
hypoventilation
Is Alveolar recoil lead to a decrease in intr-alveolar pressure?
NO
What cause the aveolar wall to collapse?
The alveolar walls can collapse due to several factors, including a decrease in surfactant production, which reduces surface tension and makes it harder for the alveoli to remain open. Conditions such as pneumonia, acute respiratory distress syndrome (ARDS), or lung fibrosis can also lead to inflammation and damage to the alveolar structure. Additionally, increased pressure from surrounding tissues or airways can contribute to alveolar collapse, known as atelectasis.
What is an example of compound alveolar?
The word "cat" is an example of a compound alveolar as it is composed of the alveolar consonants /k/ and /t/.
What is the treatment for central cord syndrome?
Usually, intravenous steroids are immediately administered to patients suspected of suffering from central cord syndrome, to decrease swelling and improve outcome. Surgery may be performed in certain cases.
What is intra-alveolar hyaline membrane?
A pathological condition characterized by the combination of fibrin and cellular debris, found inside the alveolar sacks of the lungs. They are the result of leakage of blood components into the alveolar sacks. They inhibit gas exhange and result in systemic hypoxia, with possible death in premature babies and symptoms of acute respiratory distress syndrome in adults. For example, neonatal respiratory distress syndrome features intra-alveolar hyaline membranes. This disease occurs in premature births. The newborn has not produced sufficient surfactant and so most of the alveoli in his/her lungs collapse. The few remaining alveoli are given the entire blood supply of the lung. Overloading of the blood vessels causes high hydrostatic pressure and eventual leakage of blood components into the alveoli supplied by the blood vessel. As these components accumulate, intra-alveolar hyaline membranes start to form. The membranes hinder the gas-exchange that would normally take place in the alveoli, leading to systemic hypoxia. This is the most common cause of death in premature babies.
What is alveolar macrophages also known as?
Alveolar macrophages, aka DUST CELLS.
What is alveolar ridge in Yoruba?
Alveolar ridge in Yoruba can be translated as "ilẹ̀ iigboori."
Who are some famous people with Rett syndrome?
As of 2014, there are no reported famous people who suffer with Rett syndrome. This condition affects the central nervous system.
