What is difference between anatomical dead space and phyiological dead space?
ANATOMICAL DEAD SPACEThe volume of the conducting airways of the nose,mouth,trachea down to the level of alveoli representing dead portion of inspired gas unavailable of exchange of gases with pulmonary capilary blood. PHYSIOLOGICAL DEAD SPACEIt is the combination of anatomical dead space and alveolar dead space.where as alveolar dead space is the space occupied by gas which is transported to the alveoli but does not meet blood across the alveolar capillary membrane.
What is A-a DO2?
Alveolar-arterial oxygen difference (A-a)DO2
What is the difference between pulmonary and alveolar ventilation?
nothing
What is the respiratory unit the lung called?
A functional unit of lung is called an Alveolus. one functional unit of lung consists of Alveolar sac, pulmonary capillaries and bronchial capillaries.
What is the significant difference between the attached gingiva and the alveolar mucosa is that the alveolar mucosa is?
not keratinized and, therefore, is more delicate than the gingival tissue
What is the respiratory unit in the lung called?
A functional unit of lung is called an Alveolus. one functional unit of lung consists of Alveolar sac, pulmonary capillaries and bronchial capillaries.
What is alveolar dead space?
Alveolar dead space refers to the portion of the air in the lungs that does not participate in gas exchange because it does not come into contact with the pulmonary capillaries. This can occur when there is impaired blood flow to certain areas of the lungs, leading to ventilation without perfusion. Alveolar dead space can contribute to ventilation-perfusion mismatch and can impact the efficiency of gas exchange in the lungs.
What are the smallest divisions of the bronchial trees?
bronchiolesBronchiolesThese are called bronchioles.bronchiolesbronchiolesthis is the wrong answer, The bronchioles divide into smaller and smaller tubes, ending in microscopic branches that divide into Alveolar ducts, which end in several alveolar sacs.Think of it like a bunch of grapes, the aveolar ducts are the stem, the grape clusters represent an alveolar sac, and each grape represent an alveolus.Alveoli is where the oxygen has to reach to begin gas exchanges between air and blood.Bronchioles
Label the parts of bronchial tree?
respiratory zone is from respiratory bronchioles (generation 17-19) to alveolar ducts (generation 20-22) to alveolar sacs (generation 23). It is the site of gas exhange, where velocity of gas is low, and diffusion is the dominant mechanism of gas exchange.

Which blood vessels in the lungs help your body take in and give off gases?
Its not the blood vessels that are in charge of that. The Pulmonary alveolus is an anatomical structure that has the form of a hollow cavity. Found in the lung parenchyma, the pulmonary alveoli are the terminal ends of the respiratory tree, which outcrop from either alveolar sacs or alveolar ducts, which are both sites of gas exchange with the blood as well.
What is the concept of equal pressure point?
Equal pressure point (EPP) is the point where Intrapleural pressure and Alveolar pressure are equal. This is similar to the Starling resistor concept in the lung. Instead of flow being determined by the difference between alveolar and mouth pressure- flow is determined by the difference between alveolar and Intrapleural pressure difference. In forced expiration, both intrapleural pressure and alveolar pressure will increase. However alveolar pressure will decrease along the length of the airway until a pressure of zero at the mouth, whereas intrapleural pressure will remain the same. Therefore there will be a point where intrapleural pressure will be equal and subsequently greater than alveolar pressure. If the EPP occurs in the larger cartilaginous airways, the airway remains open. However, if the EPP is in the smaller airways, it will collapse. Increasing the force of expiration does not overcome EPP since it will increase both alveolar and intrapleural pressure. Another interesting concept is that EPP moves distally as expiration progresses because as air leaves the alveolar unit, the pressure in the alveolar decreases hence the pressure in the airway decreases as well. EPP is the cause of dynamic airway compression.
