Capillaries join the arteries and veins. The circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate. [ 1][ 2] It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia ...
Cerebral circulation is the movement of blood through a network of cerebral arteries and veins supplying the brain. The rate of cerebral blood flow in an adult human is typically 750 milliliters per minute, or about 15% of cardiac output. Arteries deliver oxygenated blood, glucose and other nutrients to the brain.
Anatomical terminology. [ edit on Wikidata] The heart is a muscular organ found in most animals. This organ pumps blood through the blood vessels of the circulatory system. [ 1 ] The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs. [ 2 ]
Cardiovascular physiology. Cardiovascular physiology is the study of the cardiovascular system, specifically addressing the physiology of the heart ("cardio") and blood vessels ("vascular"). These subjects are sometimes addressed separately, under the names cardiac physiology and circulatory physiology. [1]
Circulatory system of gastropods. As in other molluscs, the circulatory system of gastropods is open, with the fluid, or haemolymph, flowing through sinuses and bathing the tissues directly. The haemolymph typically contains haemocyanin, and is blue in colour.
Current ISO 3166 country codes. The sortable table below contains the three sets of ISO 3166-1 country codes for each of its 249 countries, links to the ISO 3166-2 country subdivision codes, and the Internet country code top-level domains (ccTLD) which are based on the ISO 3166-1 alpha-2 standard with the few exceptions noted.
The renin–angiotensin system ( RAS ), or renin–angiotensin–aldosterone system ( RAAS ), is a hormone system that regulates blood pressure, fluid and electrolyte balance, and systemic vascular resistance. [ 2][ 3] When renal blood flow is reduced, juxtaglomerular cells in the kidneys convert the precursor prorenin (already present in the ...
Debian-based. Debian family tree. Debian (a portmanteau of the names "Deb" and "Ian") Linux is a distribution that emphasizes free software. It supports many hardware platforms. Debian and distributions based on it use the .deb package format [ 2] and the dpkg package manager and its frontends (such as apt or synaptic).
