Overview

Chapters

• 00:00 - 00:30: Introduction The introduction begins with a sense of curiosity about the composition of a kidney. The narrator expresses interest in exploring different parts of the kidney, particularly focusing on a white area. There is an intriguing element as it is revealed that the kidney used in this exploration has been injected with various colors, suggesting a method to better understand its structure and function.
• 00:30 - 01:00: Latex-injected Kidney Explanation This chapter discusses a demonstration involving the injection of latex of different colors into the bloodstream to visualize and understand kidney function. Red latex is used to mark unfiltered blood vessels, indicating blood that hasn't yet been cleaned by the kidneys. Blue latex indicates vessels carrying blood that has been filtered by the kidneys, showcasing the blood after it has been cleaned. Finally, yellow latex is injected into areas that hold urine, highlighting the pathways and compartments involved in urine storage. The experiment facilitates a visual inspection of these bodily processes by observing the distribution of the different latex colors in the body's blood and urinary systems.
• 01:00 - 02:00: Kidney's Tubes and Their Functions The chapter titled 'Kidney's Tubes and Their Functions' begins with an exploration of the central yellow area within the kidney, which is identified as the region responsible for holding urine. This area collects urine that has been filtered out from the blood, which is then flushed down a tube to be forwarded to the bladder. Additionally, the chapter reveals that the kidney is connected to more than just one tube; there are, in fact, three tubes associated with the kidney, highlighting the complex system involved in urine transport within the body.
• 02:00 - 04:00: Inside the Kidney and Advert Break The chapter explains the kidney's role in the human body, highlighting how kidneys clean our blood. They take in dirty blood, filter out waste products which are then excreted as urine, and return clean blood back to the body. The transportation of these substances occurs through three specific tubes, which are illustrated visually for better understanding in the chapter.
• 04:00 - 05:30: Kidney Stones The chapter titled 'Kidney Stones' explores the pathways of blood and urine in relation to the kidneys. It explains how dirty blood enters the kidneys to be filtered and clean blood is transported away from them, while urine is carried to the bladder. The chapter also hints at a detailed examination of what lies inside the kidney, particularly focusing on the area around the center.
• 05:30 - 07:30: Blood and Plasma Processing The chapter discusses the process of blood and plasma processing, focusing on the components of the kidney involved in urine collection. The presence of 'grally bits' is noted as abnormal and not typical of a healthy kidney. The narrator acknowledges an interruption from their own kidneys, implying a humorous or lighthearted tone.
• 07:30 - 08:30: Conclusion The chapter titled 'Conclusion' discusses the speaker's tendency to take breaks, during which they enjoy watching or playing a game called 'Beast Lord.' In this game, players clear land with the aid of an elephant and other animals. The game is characterized by its unique feature of collecting 500 different animals to build and defend one's territory. The speaker humorously compares the size of an elephant's kidney to a large pizza as part of the gaming experience.

• 00:00 - 00:30 I've always wondered what's inside a kidney well let's start by taking a look at this area H I wonder what this white area does well luckily this special kidney can help us figure it out notice its strange color well different parts of this kidney have been injected with different colors of
• 00:30 - 01:00 latex red latex was injected into blood vessels carrying unfiltered or dirty blood blue latex was injected into blood vessels carrying filtered blood that's been cleaned by the kidneys and yellow latex was injected into anything holding urine so let's take a look inside that same area and see what color we find
• 01:00 - 01:30 [Music] ah the central area is yellow well that means it holds urine so this area collects urine that's been removed from the blood and flushes it down this tube to be sent to the bladder but wait a sec there's more than just one tube connected to the kidney there are three
• 01:30 - 02:00 well we know this one sends urine to the bladder but what do these two do well kidneys clean our blood they take in dirty blood filter out the bad stuff which we pee out as urine and send clean blood back to the body these three things are transported in these three tubes they can be seen a little more easily on this
• 02:00 - 02:30 model this one transports dirty blood to the kidneys this one transports clean blood away from the kidneys and as we know this last one carries urine to the bladder well now that we know what enters the kidney and leaves the kidney let's find out what else is inside the kidney we'll expose this area around the center next there's a bunch of open space in
• 02:30 - 03:00 the area that collects urine but wait a sec look inside the cavities that stretch out into the rest of the kidney do you see those little kind of grally bits this is not something you'd find in a healthy kidney let me explain what's going on so a while ago oh I'm so sorry I'm receiving a signal from my own kidneys

• 05:00 - 05:30 grapefruit they can be smooth Jagged or even branched and they can clog the tubes carrying urine out of the kidneys which is a big problem but if you drink plenty of water you should be okay and look here it's hard to tell but we sliced through the opening of some tubes it looks like there's a bunch of these tubes radiating out from the
• 05:30 - 06:00 center of the kidney I wonder what they're carrying well let's consult our dyed kidney to find out all right well now look here the tubes are red and blue so they're carrying unfiltered and filtered blood to and from the edge of the kidney well what happens at the edge of the kidney
• 06:00 - 06:30 let's find out looks like a ton of blood vessels just Tangled together to figure out what's happening here let's take a look at it under a microscope this is a glomerulus there are a bunch of these in the outer area of a kidney can you tell how there's a round capsule and a ball of blood vessels inside
• 06:30 - 07:00 [Music] well blood enters this ball and then plasma is squeezed out of the blood into the capsule plasma is the part of the blood that includes nutrients and waste products our body doesn't need so at the glomerulus plasma is drawn out of the blood
• 07:00 - 07:30 then they're sent on two different Roots do you see that triangular section of the kidney well the plasma and the blood will travel through this section in blood vessels that twist and Tangle all around each other on this winding path some nutrients and water in the plasma are reabsorbed by the blood the bad stuff is Left Behind in
• 07:30 - 08:00 the end we're left with clean filtered blood and urine the urine flows into the large white area in the center before being flushed off to our bladders and remember these blue tubes from before they carry clean blood out of the kidney if we reveal the rest of the kidney we'll find it's full of the same
• 08:00 - 08:30 structures that take in dirty blood draw out plasma and reabsorb the good nutrients flush away the bad stuff as urine and return the clean blood to the rest of our bod and that's what's inside a kidney
