10 cze 2017 · In health, the glucose concentration of airway surface liquid (ASL) is 0.4 mM, about 12 times lower than the blood glucose concentration. Airway glucose homeostasis comprises a set of processes that actively maintain low ASL glucose concentration against the transepithelial gradient.
15 kwi 2018 · As blood passes through the tiny capillaries in the alveolar sacs, changing pressure gradients allow oxygen and carbon dioxide to diffuse in and out of the blood. Gas exchange in the lungs also helps maintain acid-base balance in the body.
17 lip 2023 · Three components that are crucial to fetal glucose metabolism are maternal serum glucose concentration, maternal glucose transport to the placenta, which is impacted by the amount of glucose the fetus uses, and finally, fetal pancreas insulin production.
The lung is often overlooked as a metabolically active organ, yet biochemical studies have long demonstrated that glucose utilization surpasses that of many other organs, including the heart, kidney, and brain.
Glucose homeostasis is a process that stabilizes blood glucose levels in response to changes in internal and external conditions. Central to glucose homeostasis is the secretion of the hormones insulin and glucagon from the endocrine pancreas, the islets of Langerhans.
Pancreatic β-cells and α-cells are central to the maintenance of blood glucose homeostasis. Increased blood glucose level after meals stimulates pancreatic β-cells to secrete insulin, which promotes glucose uptake in cells and lowers glucose levels in the blood.
22 paź 2024 · The proper functioning of the respiratory system depends on both the ability of the system to make functional adjustments to varying needs and the design features of the sequence of structures involved, which set the limit for respiration.
