Objectives To compare the anatomical (V D‐Ana ) and alveolar dead space (V D‐Alv ) in term and prematurely born infants and identify the clinical determinants of those indices. Working Hypothesis V D‐Ana and V D‐Alv will be higher in prematurely born compared to term born infants. ...
The meaning of PHYSIOLOGICAL DEAD SPACE is the total dead space in the entire respiratory system including the alveoli.

57 Histologically, tubular length decreases, interstitial fibrosis is seen, and tubular basement membrane constitution and anatomical features change with age. Glomerulosclerosis directly affects the glomerular filtration rate (GFR). After the age of 40 years, the GFR decreases 1 mL/min per year.58 ...
The increase in tidal volume and minute ventilation under CPAP, despite increased PaCO2, suggests an increase in dead space. This can be attributed to: (1) increased instrumental dead space related to the oronasal mask; (2) disappearance of anatomical dead space washout present under HFNC [28,...
The correlation has been checked by experiments performed in an excised portion of the right ventricle by comparison of DTMRI and histology myofiber angles [23, 24], but DTMRI time and space resolutions, especially in vivo, were too large to get an accurate map of myofiber angles. More ...
The anatomical structure of the eccrine sweat gland consists of two main functional components: a secretory coil and a duct, both made up of a simple tubular epithelium (Sato1983). The secretory coil has three types of cells: clear, dark, and myoepithelial. Upon stimulation, clear cells of ...
indicus), female buffaloes show a low predisposition towards dystocic births due to key anatomical differences, such as their pelvic and genital structure. The iliac area of buffaloes is larger than in cattle, and the fifth sacral vertebra is separated, allowing greater freedom of movement and a...
