The mesoderm produces the muscles, excretory organs, circulatory organs, sex organs (gonads), and internal skeleton.
Although ARDS occurs locally in the lungs, it is a systemic inflammatory disease involving both the lungs and other circulatory organs.
As is typical for such small animals, there are no respiratory or circulatory organs.
We obtained individual level data containing information about year of death, age at death, sex, underlying cause of death and any contributing causes of death for all people (n = 2,650,158) who died in Sweden between 1961 and 2007 and whose cause of death had been recorded as any disease of the circulatory organs.
Some evidence of early evolutionary history is the structure of the antennal heart, a separate circulatory organ consisting of two ampullae, or vesicles, that are attached to the frontal cuticle to the bases of the antennae.
The severity of UTI is graded clinically as follows: a) asymptomatic; b) causing local symptoms such as dysuria, urinary frequency, urgency, supra- or retropubic pain or bladder tenderness; c) causing general symptoms including fever, flank pain, nausea and vomiting; d) systemic inflammatory response syndrome (SIRS); and e) circulatory and organ failure.
In 1980, Tiran et al. (S105) developed a combined circulatory and organ model of glucose and insulin dynamics by building upon their previous glucose and insulin (S106) models.
Pentastomids range from a few millimetres to 14 cm (about 6 inches) in length and lack respiratory, circulatory, and excretory organs.
Unlike other bilaterians, they are acoelomates (having no body cavity), and have no specialized circulatory and respiratory organs, which restricts them to having flattened shapes that allow oxygen and nutrients to pass through their bodies by diffusion.
The lack of circulatory and respiratory organs limits platyhelminths to sizes and shapes that enable oxygen to reach and carbon dioxide to leave all parts of their bodies by simple diffusion.
Less well known, and therefore absent or minimally treated in the HAO, are the nervous system (brain, ganglia, nerves), the tracheal system, the circulatory system (pulsatory organs, heart muscles), exocrine glands, and the alimentary canal and corresponding accessory structures.
