Mucosa of the larynx. Δ The lingual surface of the epiglottis is covered by a stratified squamous non-keratinized epithelium. The laryngeal surface, on the other hand, is covered by respiratory epithelium with seromucous glands in the lamina propria. Δ Within the larynx the mucosa creates two pairs of folds: Superior.
What we’ll talk about... Histological structures of conducting airways. Histological structures that facilitate gas exchange. Properties of alveoli that control ventilation. Macrophages and handling of foreign particles. Rate of gas diffusion between air and blood is related to the surface area and thickness of the interface. Air. Blood. O2.
The respiratory system works hand-in-hand with the nervous and cardiovascular systems to maintain homeostasis in blood gases and pH. It is the level of carbon dioxide rather than the level of oxygen that is most closely monitored to maintain blood gas and pH homeostasis.
24 Ιαν 2024 · Histology of the respiratory system. Histological appearance of normal lung tissue and its components. The respiratory system consists of several organs working together to facilitate the exchange of oxygen and carbon dioxide between the air and the bloodstream, supporting cellular respiration.
The respiratory system is responsible for taking in oxygen and expelling carbon dioxide. It can be divided functionally into two regions: Respiratory epithelium is a pseudostratified ciliated columnar epithelium with goblet cells that lines much of the conducting passages.
Bronchus and bronchioles are present. Alveolar duct and alveoli-. -Simple squamous epithelium. Type 1 Pneumocytes(97%. -Blood Air barrier. Type2 Pneumocytes(2%) - pulmonary surfactant. - lamellar bodies. Type3Pneumocytes (brush cells) -Macrophages or Dust cells.
