English: Veins and Capillaries Tissue fluid is the liquid component of blood that flows past the capillary wall to bathe tissue cells. Water, sugars, salts, fatty acids, amino acids, coenzymes, and hormones, as well as waste products from the cells, make up the majority of it.
A capillary is a small blood vessel, from 5 to 10 micrometres in diameter, and is part of the microcirculation system. Capillaries are microvessels and the smallest blood vessels in the body. They are composed of only the tunica intima (the innermost layer of an artery or vein), consisting of a thin wall of simple squamous endothelial cells. [2]
The trunk of the body contains, from superior to inferior, the thoracic region encompassing the chest [1] the mammary region encompassing each breast; the sternal region encompassing the sternum; the abdominal region encompassing the stomach area; the umbilical region is located around the navel; the coxal region encompassing the lateral (side ...
In vertebrates, the circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the body. [1] [2] It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia meaning heart, and Latin vascula meaning vessels).
Anatomography is an interactive website which supports generating anatomical diagrams and animations of the human body. The Anatomography website is maintained by the DBCLS (Database Center for Life Science) non-profit research institute located at the University of Tokyo.
Peritubular capillaries surround the cortical parts of the proximal and distal tubules, while the vasa recta go into the medulla to approach the loop of Henle. [1] [2] About one-fifth of the blood plasma is filtered into Bowman's capsule as the blood passes through the glomerular capillaries; four-fifths continues into the peritubular capillaries.
Gross anatomy - systemic or region-wise study of human body parts and organs. Gross anatomy encompasses cadaveric anatomy and osteology. Comparative anatomy - the study of evolution of species through similarities and differences in their anatomy. Microscopic anatomy . Cell biology and cytogenetics. Surface anatomy.
In a healthy vascular system, the endothelium lines all blood-contacting surfaces, including arteries, arterioles, veins, venules, capillaries, and heart chambers. This healthy condition is promoted by the ample production of nitric oxide by the endothelium, which requires a biochemical reaction regulated by a complex balance of polyphenols, various nitric oxide synthase enzymes and L-arginine.
