What else can I help you with?
How does ventilation occur?
Pulmonary ventilation occurs as a person inhales and exhales air and air is exchanged between the atmosphere and the alveoli of the lungs. During this, the pulmonary capillary blood gains oxygen and loses carbon dioxide.
What determines in which direction carbon dioxide and oxygen will diffuse in the lungs?
pressure difference between carbon dioxide and oxygen level between pulmonary artery and alveolar space
What is the difference between external ventilation and internal ventilation?
External respiration, the process by which gases are exchanged between the atmosphere and the pulmonary loop of circulationWhereas,Internal respiration: the is the gaseous exchange between the blood and tissue ( and also cells)
What is the difference between pulmonary fibrosis and pulmonary sclerosis?
They are essentially the same.
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 difference between ventilation and gaseous exchange?
Gaseous exchange is a natural process, ventilation is a forced process.
What is the difference between pulmonary system and coronary system?
Coronary or cardio is blood flow. Pulmonary or respiratory is breathing.
Which part of the respiratory system consists of air sacs with capillaries?
That sounds like a general description of the LUNGS.The lungs are loaded with pulmonary alveoli: small outpouchings along the walls of the alveolar sacs and alveolar ducts; through them, gas exchange takes place between alveolar gas and pulmonary capillary blood.
What happens if transpulmonary pressure decreases?
If transpulmonary pressure decreases, it may indicate a decrease in the difference between alveolar pressure and intrapleural pressure. This can lead to decreased lung expansion and ventilation, potentially resulting in reduced oxygen exchange and impaired respiratory function.
What is alveolar dead space?
Alveolar dead space is the difference between anatomical and physiologic dead space, representing the space of alveoli occupied by air that does not participate in alveolar ventillation (oxygen-carbon di oxide exchange). Anatomical dead space: the Airways of mouth, nose, pharynx, larynx, trachea, bronchi, and the broncheoles. Equipment dead space is the volume of equipment that occurs in rebreathing of gases. Physiologic dead space is the sum of the anatomic and alveolar dead spaces Its volume VD is determined by measuring the partial pressure of carbon di oxide in a sample of exhaled gas (PE) and with tidal volum e(VT) using the formula VD/VT =[ (PCo2-PECo2)/PaCo2
What is an alveolar plateau?
An alveolar plateau refers to the phase during a pulmonary function test when stable alveolar gas exchange occurs, resulting in a horizontal line on the volume-time curve. This plateau indicates that sufficient time has elapsed for oxygen and carbon dioxide to equilibrate between the alveoli and the capillaries. It is used to assess the efficiency of gas exchange in the lungs.
What condition is indicated by the structural difference between systemic and pulmonary arteries?
Elatic recoil.
