Hadith 1

d to benefit it with some sensory feeling. Rather, its flesh is fragrant so that the air in it can penetrate a lot more than what is needed by the heart, so that it is for the animal when it is submerged in the water, and when it makes a long continuous sound that distracts it from breathing and attracting the air, and when the person is relieved of inhaling stinky air or air mixed with smoke or dust, the prepared air it takes, the heart should be certain by contraction to push out the smoky air and to exhale. The reason for the whiteness of its flesh is the high frequency of air in it and its predominance over what it feeds on, but it is divided into branches so that breathing is not disrupted by a calamity that mighty afflict one of the branches. And there are not lungs for the fish and it breathes the air from the path of the ears. As for the trachea of the lung, it is made up of many cartilages, some of them stacked on top of each other, connected to each other by ligaments, some of which are complete circles, and they are inside the lung, and some are semi-circular, and they are the one that adjoins the oesophagus and touches it in the space of the throat, and between each two of them there is a gap and it crosses it. Two membranes run over it and include the vulva that is between it and connect the two ends of its halves inside and outside, but they are made cartilaginous so that they remain open and do not fit, and so that its hardness is a reason for the occurrence of sound or a helper in it. And rather, they were multiplied so that the lesion would not be covered by it; and rather, they were tied with membranes to expand sometimes and gather at other times when inhaling and breathing, for what is capable of expansion and meeting is the membrane without the cartilage, but it meets the oesophagus with its missing side and the membrane to push away from the face of the penetrating bite if the oesophagus needs to expand and widen. It flattens into the membrane and takes a portion from the space of the stalk It expands and penetrates the bite easily, so the cavity of the trachea will then be a support for the oesophagus when it grows, and the inner membrane is made harder and smoother in order to resist the sharpness of the storms, the bad breath and the smoke coming from the heart, and so that it does not relax from the occurrence of the sound. However, inside the lung, it was divided into many sections so that a lot of air could penetrate into them and prepare the heart in them, and its benefit in preparing air for the heart is like the benefit of the liver in preparing food for the whole body. And rather it’s orifices are narrowed so that the breeze penetrates through it to the arteries leading to the heart gradually, and that the blood does not penetrate into them, thus causing blood spitting. As for the heart, it is composed of flesh, nerves, cartilage, veins and arteries that sprout from it, ligaments that are attached to it, and a thick membrane that covers it for protection and is not attached to it except at its origin, lest it be compressed when diastolic. As for its flesh, it is solid, thick, woven from three types of fleshy fibrous, long, attractive, broad, motivating, and edging, so that it has different types of movements and actions and its rigidity so that it does not get excited by speed and to be farther from accepting pests. Fulfilment of the plant and its cartilage has a solid basis, and it is like the rule for it. It has three cavities called bellies, two of which are large, and the third in the middle is small, called the vestibule, and the right is a solid blood vessel that has problems with its core. And the left one is a container for the soul and gentle blood, and it is distinguished by increasing hardening of insecurity from the dissolution of what is in it and its filtering for subtlety of one and the tenderness of the other i
