blood from the heart to all the organs. The veins are meant to transport deoxygenated or blood devoid of oxygen from the organs to the heart so that it can gain oxygen again. Capillaries are the tiniest blood vessels of the body and serve as the transition link between arteries and veins....
Bile acids are the major metabolites of cholesterol catabolism in the liver. Two synthetic pathways exist: the classical pathway and the alternative pathway [6]. The classical pathway is responsible for the synthesis of primary bile acids, cholic acid (CA) and chenodeoxycholic acid (CDCA). It is...
Fluid normally exchanges freely between the plasma and interstitial space and is returned primarily via the lymphatic system. This balance can be disturbed by diseases and medications. In inflammatory disease states, such as sepsis, the return flow of fl
In biology and physiology, an "organ system" is a group of different organs that work together to serve an essential function in the body. Some examples of organ systems include the nervous system (the brain, spinal chord, and nerves), the circulatory system (the heart and blood vessels),...
The major components of the lymphatic system include lymph, lymphatic vessels, and lymphatic organs that contain lymphoid tissues.
