Cursed images of my stop motion figure and animation part 3
here is the animation if you didnt saw it:
I forgot her at friend's, but Nep is chillin with Vriska now
If I had a nickel for every dorky, duck-loving dad I encountered in media
I'd have two nickels. Which isn't a lot, but it's crazy that it's happened twice.
Do you guys like farming? pt.2 (Coral island edition)
playing these games that has romance as an aromantic is really fun ngl (I REALLY WANTED TO MARRY FRANK BUT THEN HE TURNS OUT TO BE MARRIED TO SOMEONE ELSE AND THEN MARK APPEARS OUT OF NOWHERE LIKE A BRAZILLIAN SOAP OPERA SCENE)
Today I was at a climate vision lecture
with the school. And the guy presenting this asked who would eat bugs if given the chance. Some have claimed they will. Then the guy pulled out a packet of mealworms from behind his back. Everyone laughed and few ate a meal or two. The funny thing was, I couldn't have eaten them anyway. He listed the allergens in it: shellfish and dust mites. No thats my question: Why the hell is there dust in something you're supposed to eat? I mean how? How is that legal that there's freakin dust in it?!
WHO WAS GOING TO TELL ME ALEX G WORKED ON THE I SAW THE TV GLOW SOUNDTRACK.
“who asked” i did. keep talking. tell me more. what happened after that.
Former gifted kid doesn’t immediately understand her homework and breaks down at her work desk (three dead, five injured)
Check out my news cartoon voice over on my channel and don’t forget to leave a like and comment I’d love to hear from you …
I love how big hero six shows all the flavours of autism
That bee sure is ready
FISH POSTING !!!!!
My laugh was like a Hiena
This link goes to chapter 5 but there is more:
Be warned I DID NOT READ AHEAD SO PLEASE READ THE TAGS

Blood cell
The blood cells serves as a comprehensive guide to understanding the intricacies of hematopoiesis, the process through which various blood cell types are formed and function in the human body. This detailed discussion aims to unravel the key aspects presented in the article, delving into the structure, functions, and disorders associated with;
Red blood cells (erythrocytes),
2.White blood cells (leukocytes), and
platelets (thrombocytes).
Blood Cell Types and Composition
At the core of the circulatory system lie three major types of blood cells: red blood cells, white blood cells, and platelets. These cellular components collectively contribute to 45% of blood tissue by volume, with the remaining 55% being plasma. This delicate balance underscores the dynamic nature of blood, serving as a conduit for various vital functions within the body.
1.Red Blood Cells (Erythrocytes)
The discussion commences with a focus on red blood cells, the primary carriers of oxygen in the bloodstream. Erythrocytes, characterized by their unique biconcave shape and lack of a nucleus, play a crucial role in gas exchange facilitated by the iron-containing protein hemoglobin. The intricate details of erythropoiesis, the process of RBC formation in the red bone marrow, offer a glimpse into the remarkable physiological mechanisms that ensure a constant supply of oxygen carriers. The staggering production rate of 2.4 million RBCs per second in adults highlights the body’s continuous demand for these essential cells. The information regarding the lifespan of RBCs (100–120 days) and their subsequent removal by the spleen adds another layer to our understanding of the life cycle of these vital cells. The absence of a nucleus in mature red blood cells, a unique characteristic among human cells, is highlighted. The pathological conditions of anemia and polycythemia are thoroughly explored, shedding light on the consequences of an imbalance in red blood cell count. Additionally, the erythrocyte sedimentation rate (ESR) provides valuable insights into the diagnostic tools used in assessing the health of red blood cells.
2.White Blood Cells (Leukocytes)
The immune system, our body’s defense mechanism, relies on white blood cells to combat infectious diseases and foreign materials. These leukocytes, originating from multipotent cells in the bone marrow, are categorized into granulocytes (basophils, eosinophils, neutrophils, mast cells) and agranulocytes (lymphocytes and monocytes). The discussion delves into the roles these distinct white blood cell types play in the human immune system, offering a nuanced understanding of their functions. The conditions of leukopenia and leukocytosis, indicating low and high white blood cell counts, respectively, are explored, emphasizing the diagnostic significance of monitoring these counts. The increased white blood cell count during infections and its association with hematological cancers underscore the pivotal role leukocytes play in our overall health.
3.Platelets (Thrombocytes)
The section on platelets elucidates their role in hemostasis, the process of preventing and stopping bleeding. These small, irregularly shaped cell fragments, derived from megakaryocytes, circulate in the blood and are essential for the formation of blood clots. The average lifespan of platelets, a mere 5 to 9 days, emphasizes the continuous production required for maintaining hemostatic balance. The normal range of platelet counts and the potential consequences of low or high platelet numbers provide valuable insights into the delicate equilibrium necessary for preventing excessive bleeding or the formation of thrombosis. Thrombocytopathy, a broad term encompassing disorders related to platelets, is discussed, including thrombocytopenia, thrombasthenia, and thrombocytosis. The intricate relationship between platelets and growth factors, as well as their role in wound healing, showcases the multifaceted contributions of these small but crucial cellular fragments.
Complete Blood Count (CBC): The article introduces the Complete Blood Count (CBC) as a vital diagnostic tool providing a comprehensive analysis of blood cell composition. The historical transition from manual counting to automated analyzers reflects the evolving landscape of medical technology, enhancing the efficiency and accuracy of blood cell analysis. The significance of CBC in offering an overview of a patient’s general health status is underscored, emphasizing its widespread use in medical diagnostics.
Historical Discoveries.
The historical perspective woven into the article traces the evolution of our understanding of blood cells. From Jan Swammerdam’s pioneering observation of red blood cells in 1658 to Paul Ehrlich’s techniques in staining blood films and differential blood cell counting in 1879, the narrative highlights key milestones in the establishment of hematology as a distinct field of medicine. The contributions of various scientists, including Antoni van Leeuwenhoek, Alfred Donne, and Gabriel Andal, collectively shaped our current knowledge of blood cells.
Conclusion
The blood cells provides a rich tapestry of information encompassing their structure, functions, and associated disorders. It serves as a comprehensive resource for understanding the dynamic nature of blood and the pivotal roles played by red blood cells, white blood cells, and platelets in maintaining homeostasis within the human body. The integration of historical discoveries adds depth to the narrative, highlighting the continuous quest for knowledge that has defined the field of hematology. This article not only serves as an educational tool but also showcases the remarkable advancements in medical science and technology that have propelled our understanding of blood cells to new heights. As we unravel the mysteries of hematopoiesis, we gain valuable insights into the machinery that sustains life within our veins.

Here is an update on my frog no one asked for:
He lost both arms an all toes on one foot
"it's time to post something funny" whispered my narrator, but little did we know it was my sister.
I FINALLY FINISHED IT. idk why it took me SO FUCKING LONG. 😭😭
