On the genius of general theory of relativity :")

too poetic that it lost the scientific credibility

[standing between Kennedy and Reagan] Hmm, all three of us took bullets. Well, I know why we're smiling. We survived.

Actually, the RBC is a “bag” that can be deformed into almost any shape. Furthermore, because the normal RBC cell has a great excess
of cell membrane for the quantity of material inside, deformation does not stretch the membrane greatly and, consequently, does not rupture the cell, as would be the case with many other cells.

#Erythropoiesis

هو الfancy name لعملية تكوين كريات الدم الحمر 🌚🍻

بالأجنة:
- بالأشهر الثلاثة الاولى، تتكون الRBCs بطبقة الmesenchyma الموجودة بلyolk sac

- بالاشهر الثلاثة الوراها رح يبدي تكوين الRBCs بالكبد بشكل اساسي (ولهذا هاي المرحلة يسموها بلhepatic stage)، وهمين بالطحال والأعضاء اللمفية.

- بالاشهر الاخيرة رح يبدي نخاع العظم bone marrow وية الكبد بتكوين أغلب الRBCs

#physiology

بالبالغين:
لحد عمر ال20، البالغين يصنعون الRBCs بنخاع كل العظام تقريباً (العظام الطويلة والمسطحة). لكن ورة عمر ال20 نخاع العظام الطويلة يتحول لyellow marrow يخزن الدهون بدون ميصنع كريات الدم الحمر. وينحصر تصنيعهن بلmembranous bones مثل:
- Sternum
- Ribs
- vertebrae
- Ilia (ilium)
- Scapula
- ends of long bones
لأن هاي العظام هي الوحيدة التحتوي على الred marrow اللي يتم بيه تصنيع كريات الدم

In case the bone marrow is damaged, liver and spleen will start producing RBCs to compensate the loss

'The nuns taught us there are two ways through life … the way of Nature… and the way of Grace. You have to choose which one you'll follow.
Grace doesn't try to please itself. Accepts being slighted, forgotten, disliked. Accepts insults and injuries.
Nature only wants to please itself. Get others to please it too. Likes to lord it over them. To have its own way. It finds reasons to be unhappy... when all the world is shining around it... when love is smiling through all things.
They taught us that no one who loves the way of grace... ever comes to a bad end.'

'Brothers, have no fear of men's sin. Love a man even in his sin, for that is the semblance of Divine Love and is the highest love on Earth. Love all of God's creation, the whole and every grain of sand in it. Love every leaf, every ray of God's light. Love the animals. Love the plants. Love everything. If you love everything, you will perceive the divine mystery in things. Once you perceive it, you will begin to comprehend it better everyday. And you will come at last to love the whole world, with an all-embracing love.'

- Brothers Karamazov by Dostoyevsky
