it is a part in the heart which reforms the bases of the muscle contamination in the heart.
"Venoules" is likely a misspelling of "venule," which is a small blood vessel that carries blood from capillaries to veins. These vessels are important for returning blood from tissues back to the heart.
The blood travels around the human body through blood vestals slowly or fast depending on what your heart beat is like.Blood from heart goes to artery, then arteriole, then to capillary, which goes venule, then to the vein, then the blood goes back to the heart.
Here we go! [First, the pulmonary circuit.] R atrium; R ventricle; pulmonary artery (L or R); arteriole; capillary adjacent to an alveolus of lung; venule; pulmonary vein [Now the blood returns to the heart for the systemic (body) circuit.] L atrium; L ventricle; aorta; R iliac artery; arteriole; capillary in a toe of the R foot; venule; R femoral vein; vena cava; back to the R atrium
The activity of the kidneys is controlled by hormones which have been released by a gland in the brain and by the composition of the blood.The kidney, better yet, a kidney nephron has three main functions: ultrafiltration, in which contents of the blood are filtered according to their size (Bowman's Capsule); reabsorption, in which needed substances (water, glucose, amino acids, some salts; unneeded: urea, uric acid, some salts) diffuse (by active transport) into the venule end of a capillary bed (renal tubules and, partially, Henle's Loop as well as the collecting duct); osmoregulation, in which ADH (antidiuretic hormone) is released by the pituitary gland in the brain (renal tubules and, partially, Henle's Loop as well as the collecting duct).The kidney has more than one activity, so several things perform the activities.
The left anterior tibial vein drains into the veins leading into the inferior vena cava, which empties in the right atrium. The right atrium pumps into the right ventricle. The right ventricle pumps this deoxygenated blood into the pulmonary trunk which splits into two branches left and right which transport the doexygenated blood on to vasculature in the lungs. This circuit essentially turns around in the alveolar capillaries where gas exchange occurs, oxygenating this blood and turning it from blue to red. This blood drains into a return system, draining this oxygenated blood from capillary to venule to vein, gathering in the right and left pulmonary vein. (vein doesn't always mean blue blood. Vein means that it is returning to the heart and artery means leaving the heart. In the body system this means that arteries are red and veins are blue, but in the pulmonary circuit, it's the opposite with regard to color. Don't rely on blood color to remember this, rely on direction of transport to and from the heart). The blood enters the left atrium through the mitral valve and into the left ventricle which pumps through the aortic valve into the aorta which feeds the systemic circuit. Off of the aorta there are many branches leading to areas of the body such as the head, upper torso, legs, etc. One of these branches, the brachiocephalic trunk, will split into two branches. The one on the thumb side of the forearm is the right radial artery.
A venule is a smaller version of a vein.
A vein is larger than a venule. It is also closer to the heart and farther from the capillaries than a venule.
Artery -> Arteriole -> Capillary -> Venule -> Vein

Microcirculation
An arteriole transports oxygenated blood from the arteries to the capillary beds and a venule transports de-oxygenated blood from the capillary beds to the veins.

By the process of diffusion.
true
Hydrostatic pressure is the force the gains the ECF from blood at the ends of the arteriole and venule. This process depends heavily on gravity for it to work properly.
The arterioles wall contains smooth muscle and elastic fibers and is six times thicker to handle the higher pressure in the arterioles. The venule is like a giant capillary.
A tiny vein is known as a venule. A tiny artery is an arteriole.
