الْبِنَاءُ الْمُحْكَمُ فِي الْجُرُوحِ الْخَارِجِيَّةِ.

The precise structure in external wounds.

أَمَّا الْجِلْدُ وَهُوَ الْغِلَافُ الْخَارِجِيُّ لِلْإِنْسَانِ فَإِنَّ اللَّهَ -سُبْحَانَهُ وَتَعَالَى- جَعَلَهُ مُتَجَدِّدًا، فَيَتَغَيَّرُ وَيَتَجَدَّدُ عَنْ طَرِيقِ انْقِسَامِ خَلَايَا الْجِلْدِ الْكَثِيرَةِ، وَإِذَا جُرِحَ الْإِنْسَانُ فَإِنَّ الْجِسْمَ يُوَاجِهُ الْمَوْقِفَ بِسُرْعَةٍ، إِذْ تُوجَدُ فِي الدَّمِ مَادَّةٌ تَجْعَلُهُ سَائِلًا، فَإِذَا مَا جُرِحَ الْجِسْمُ وَخَرَجَ الدَّمُ يَحْدُثُ التَّجَلُّطُ (تَجَمُّعُ الدَّمِ) مُكَوِّنًا قِشْرَةً حَمْرَاءَ، ثُمَّ يَعْمَلُ الْجِسْمُ عَلَى تَقْرِيبِ حَافَتَيِ الْجُرْحِ وَإِزَالَةِ الْجِلْدِ التَّالِفِ وَإِقْفَالِ فَجْوَةِ الْجُرْحِ بِأَلْيَافٍ قَوِيَّةٍ وَتَنْكَمِشُ الْفَجْوَةُ بَعْدَ ذَلِكَ لِتَنْمُوَ طَبَقَةٌ جِلْدِيَّةٌ (خَلَايَا جِلْدِيَّةٌ جَدِيدَةٌ) وَيَكُونُ النُّمُوُّ بِسُرْعَةٍ أَكْثَرَ مِنَ السَّابِقِ لِتَعْوِيضِ مَا فَقَدَهُ الْجِسْمُ مِنْ خَلَايَا تَالِفَةٍ وَتَعُودُ سُرْعَةُ النُّمُوِّ إِلَى الْحَالَةِ الِاعْتِيَادِيَّةِ بَعْدَ ذَلِكَ، مِمَّا يُسَاعِدُ عَلَى حِمَايَةِ الْجِسْمِ مِنَ الْأَعْدَاءِ الَّتِي قَدْ تَدْخُلُ مِنَ الْجُرُوحِ غَيْرِ الْمُلْتَئِمَةِ بِفَضْلِ هَذِهِ السُّرْعَةِ وَعَدَمِ تَعْرِيضِ الْجِسْمِ لِلْأَعْدَاءِ.

As for the skin, which is the external covering of the human being, God—Glory be to Him and Exalted—made it regenerative; it changes and renews itself through the division of the numerous skin cells. When a human is wounded, the body faces the situation quickly, as there is a substance in the blood that keeps it liquid. When the body is wounded and blood flows out, clotting (the gathering of blood) occurs, forming a red scab. Then, the body works to bring the edges of the wound together, remove the damaged skin, and close the wound gap with strong fibers. The gap then shrinks so that a skin layer (new skin cells) can grow. The growth is faster than before to compensate for the damaged cells the body has lost, and the growth rate returns to the normal state afterward, which helps protect the body from enemies that might enter through unhealed wounds, thanks to this speed and the avoidance of exposing the body to enemies.
