These three branches branch to four directions: Two lateral units start to the foot from the direction of the fibula ( al-qa ṣ abat a ṣ - ṣ u ġ r ā ) and two units from the inside: one to the upper part of the foot and the little toe ( al- ẖ in ṣ ir ) branches off. The second department is the one that mixes with the side units that branched off from the previously mentioned internal branch ( al-ins ī y ). The latter two components off at the lower parts of the foot. Description of the arteries (Ibn S ī n ā 1987: Volume 1. / Book 1. 81-84 p.) The ’pulsating blood vessels’ ( al-‘ur ū q a ḍ - ḍ aw ā rib ), in other words, the arteries (aš-šar ā y ī n), were created to be bilayere d 85 The source of the arteries from the two cavities of the heart ( min ta ǧ w ī fay al-qalbi ) is the left cavity ( at- ta ǧ w ī f al-’aysar ) ( ventriculus sinister cordis ). ( ḏā t a ṣ - ṣ if ā qayn ). Of the two layers, the interior is more solid because it is the meeting point of the two layers. The essential nature of the divine soul ( ar-r ūḥ ) (carried by the arteries) is its strong movement. The purpose of this is to protect and preserve its essence, to strengthen its keeping vessel. 86 Because the right hole is closer to the liver, it is necessarily responsible for attracting and processing food. 87 Anatomy of the venous artery (as-širy ā n al-war ī d ī ) (arteria venosa / pulmonary vein ) 88 1. One of these ends in the lungs and branches off in it to absorb the breath and to carry from the heart to the lungs the blood that feeds the latter. Because the heart is the mediator of nourishment for the lungs, blood comes from the heart to the lungs. The origin of this blood vessel is in the most delicate part of the heart, First, two arteries exit the left ventricle: 89 where the veins that enter it penetrate. This artery is single-layered, unlike other arteries, so it is called a venous artery ( aš-širy ā n al- war ī d ī ). It was created as a single layer to be more refined, more flexible, and more suitable for expansion and contraction. Thus it is better suited to disperse the fine-textured, vaporous blood into the lungs that corresponds to the essence of the lungs and is very similar to the blood that has matured in the heart.This blood does not need further maturation than the blood that enters the heart through the empty vein. Mainly not because the lungs are close to the heart, so hot, mature nutrients can be easily accessed. The part that pulses in it is a thin / small part, but you should not be afraid of it breaking apart during pulsation as it is vital. It does not need to increase its mass like the other strong arteries adjacent. The arterious vein ( al-war ī d aš-širy ā n ī ) ( vena arteriosa / pulmonary artery ) 90 The venous artery ( aš-širy ā n al-war ī d ī ) ( arteria venosa / pulmonary vein ) is close to the lungs; in fact, it is only the posterior part that runs past the spine. 91 The other artery, whichever is greater, was called the aorta of Aristotle. As it exits the heart, it gives two branches: the larger one bypasses the heart; and offers branches in different parts ( a. coronaria sinistra ). The other unit, the smaller one, turns around and branches off in the right ventricle ( a. coronaria dextra ). What is left out of these two small blood vessels; it is the aorta itself. As it separates from the heart, it splits into two parts: the larger part ( arcus aortae / aorta descendens ) nourishes the descending blood vessels ( murašši ḥ lil-in ḥ id ā r ), as the smaller vessel ( truncus brachiocephalicus ) travels upwards into the blood vessels above the heart ( murašši ḥ lil-i ṣʻā d ) . branches only in the front half of the lung and then penetrates deep into larger and smaller parts. If we compare the strength ( al-wi ṯā qa ) and the elasticity ( as-sal ā sa ) of this ’artery’ ( aš-širy ā n al- war ī d ī ), which allows it to easily expand and contract and thus disperse the blood that is in it, then we find that it needs flexibility more than it does strength and thickness. 92 delivered. The wall of the left ventricle is actually the thickest part of the heart. This is where the great blood stream begins, the blood pumping into the aorta with tremendous force. The aortic valve therefore ossifies into older mammals in old age. (This has already been observed by IbnS ī n ā . 1987: Volume 2, Book 3. 1196 p.) The right ventricle has a much thinner wall than the left. 90 Fonahn, serial number 3340. 91 Only one lung vein is examined or described. 92 Blood flows in the blood vessels very slowly, oozes, according to the idea taken from antiquity. The artery ( aortic descendens ) that nourishes downward blood vessels has been created to accommodate the larger number and size of parts that are under the heart. At the aorta exit, there are three complex valves that open from 18 Year 2022 Global Journal of Medical Research Volume XXII Issue I Version I ( D ) K © 2022 Global Journals Basics of the Medieval Arabic Medicine: The Vascular Systems in the Canon of Medicine of Avicenna Incorporating a Translation of a Part of the First Book 85 The wall of each blood vessel (artery, vein) consists of three layers. The structure of the layers of the arteries varies, (not their number), depending on how close or far they are from the heart. In the description these are probably not essential layers, as they are not visible to the naked eye. 86 Fonahn, serial number 3197. 87 Here food becomes the substance of the heart. This is because the third digestion takes place in the organs, during which the food that comes in the blood, becomes the substance of the organ, that is, it is absorbed. The liver rules over the rightside of the body. According to the Galenic idea the liver is the place of the second digestion and here has the origin of veins and the site of blood formation. 88 Fonahn, serial number 2988. The pulmonary vein (actually has not one but 4 pulmonary veins) arrives in the left atrium from the lungs and does not leave the left ventricle toward the lungs. The description of the role of the artery is rather fits pulmonary artery, starting from the right ventricle to the lungs. The two heart valves mentioned later (left venous or mitral valve), on the other hand, are true for pulmonary vein(s) in the left ventricle. ’The veins that come to him, to the finest part of the heart’, can be pulmonary veins ( vv. pulmonales ). 89 The right and left halves of the heart are defined not only anatomically but also philosophically. The left half of the heart, and within it the left ventricle, contains the finer, more ethereal matter. This is the nobler part of the heart, and the arteries that follow from it, which transmit the divine immortal part of the soul to the rest of the body, are nobler than the veins to the rightside of the heart (by the lower empty vein / v. cava inferior ), which are denser, heavier, nutrient-filled blood is
