The pathway of air through avian lungs has been a matter of controversy for a long time (reviewed byBretz and Schmidt-Nielsen, 1971). Numerous hypotheses have been set up, some allowing air flow through lungs only during inspiration or only during expiration; and the air flow direction during...
Diesel exhaust particles (DEPs) promoted the synthesis of melatonin in a cultured cell line (RAW 264.7 cells) and rat alveolar macrophages via the expression of the gene encoding for AANAT through a mechanism dependent on activation of the NFκB pathway. Expression of the genes encoding AANAT, ...
Trace your pathway through the respiratory tract beginning in the nasal cavity to the point where you enter the pulmonary capillaries. What are the lungs? Gas exchange between the air in the lungs and the blood takes place in the ___. (a) alveoli (b) primary bronchi (c...
If solutions of drugs are applied to the surface of the olfactory epithelium, they diffuse along the olfactory axons into the olfactory bulb and then deeper into the brain or cerebrospinal fluid. This “nose-to-brain” route has been a topic of intense research, and is an efficient pathway ...
For each comparison, barplots indicate the -log10(FDR) of the Komogolomov-Smirnoff test p-value for each pathway. C) AT2 activated progenitor score derived from scRNAseq of bleomycin treated mouse lung used to deconvolute bulk RNA-seq of T and ET mice exposed to 50 μg PM or PBS, ...
Lungs: The lungs are the organs responsible for gaseous exchange. The process involving the exchange of oxygen inside and carbon dioxide outside of the cell is known as a gaseous exchange. This cellular process is dependent on the...
(apurinic/apyrimidinic sites) in the olfactory bulbs, frontal, cortex, and hippocampus were all observed in feral dogs residing in high-pollution areas. The nasal pathway is implicated as a major portal of entry since dogs exposed to high levels of urban pollution also exhibit tissue damage ...
Express Air Dominates As Pathway For Counterfeit Goods CAPE essentially measures the potential energy a rising air parcel would gain while CIN is essentially the opposite, measuring the ambient air's tendency to resist rising (also called negative buoyancy). Air Mass Storms: They're generally easy...

(4) posterior thoracic, on the dorsal side. The main function of the air sacs in birds is to draw air through the lungs, especially during flight, to regulate heat, and to alter the specific gravity of the birds while swimming and diving. Many skeletal bones in birds (femur, humerus, ...
