Proses Pembentukan Urine (Filtrasi, dan Reabsorpsi, dan Augmentasi)
Summary
TLDRIn this video, Azi Oktaviani explains the process of urine formation in the kidneys, highlighting the roles of filtration, reabsorption, and excretion. The process occurs in each nephron of the kidneys, starting with filtration in the glomerulus, where water, salts, glucose, and waste are filtered. Reabsorption follows, where useful substances like glucose and amino acids are absorbed back into the bloodstream. Finally, excretion ensures the removal of waste from the body. Azi encourages viewers to maintain kidney health and concludes with a friendly sign-off.
Takeaways
- 😊 The process of urine formation occurs in each nephron in the kidneys.
- 💧 The main organ in the urinary system is the kidney, responsible for filtering toxins from the body.
- 🌀 The first stage of urine formation is filtration, where blood in the glomerulus is filtered, excluding large molecules like red blood cells and proteins.

- ⏱ In a normal state, 125 cc of filtrate is produced per minute from both kidneys.
- 🔄 The second stage is reabsorption, where useful substances such as glucose, salts, amino acids, and water are reabsorbed back into the bloodstream.
- 🚰 Reabsorption happens as the filtrate moves through the tubules surrounded by nephrons.
- 🚮 The third stage is augmentation, where waste molecules that the body no longer needs are excreted in the urine.
- 🛤 The urine travels through the collective tubules in the kidney, then passes through the ureters, bladder, and finally the urethra.
- 💡 The video emphasizes the importance of kidney health and encourages viewers to take care of their kidneys.
Q & A
What is the main organ responsible for the urinary system?
-The main organ responsible for the urinary system is the kidney, which functions as the body's waste processing plant to filter out toxins.
What are the three main processes involved in urine formation?
-The three main processes involved in urine formation are filtration, reabsorption, and augmentation.
What occurs during the filtration process?
-During filtration, blood flows through the glomerulus, where water, salts, glucose, urea, and other small molecules pass through the porous capillaries, while larger molecules like red blood cells and proteins are retained.
What is the role of the glomerulus in the filtration process?
-The glomerulus is a cluster of capillaries with high pressure and porous walls, which allows small molecules to pass through while filtering out larger molecules.
Where is the filtrate collected after the filtration process?
-The filtrate is collected in Bowman's capsule after the filtration process and is referred to as glomerular filtrate or primary urine.
How much filtrate is produced per minute under normal conditions?
-Under normal conditions, about 125 cc (milliliters) of filtrate is produced per minute by both kidneys.
What happens during the reabsorption process?
-During reabsorption, useful substances like glucose, salts, amino acids, and water are reabsorbed from the primary urine into the bloodstream to be used by the body.
Where does reabsorption occur in the kidney?
-Reabsorption occurs as the filtrate passes through the tubules of the nephron, which are surrounded by blood vessels.
What is the purpose of the augmentation process?
-The purpose of augmentation is to expel waste molecules that are no longer needed by the body, maintaining fluid homeostasis by excreting them as urine.
How does urine travel from the kidneys to the outside of the body?
-Urine is transported from the kidneys through the ureter to the urinary bladder, and eventually expelled through the urethra.

👋 Introduction to the Urine Formation Process
In this video, Azi Oktaviani introduces the topic of urine formation and explains that the process occurs in each nephron of the kidneys. The main steps discussed are filtration, reabsorption, and augmentation. She emphasizes that the kidneys play a critical role in filtering toxins from the body and maintaining overall health.
🩸 Filtration: The First Step in Urine Formation
The first stage of urine formation is filtration. This process occurs in the glomerulus, a cluster of capillaries with high blood pressure. The pressure forces water, salts, glucose, urea, and other small molecules through the porous glomerulus, while larger molecules like red blood cells and proteins are retained. The filtrate is collected in Bowman's capsule and is called glomerular filtrate or primary urine. Under normal conditions, the kidneys produce 125 cc of filtrate per minute.
🔄 Reabsorption: Reclaiming Useful Substances
Reabsorption is the second phase of urine formation, where useful substances like glucose, salts, amino acids, and water are reabsorbed into the bloodstream. Although the filtrate still contains these beneficial materials, they must be reabsorbed through the nephron tubules to ensure the body retains what it needs for proper function. This phase is essential for maintaining the body's nutrient balance.
🚰 Augmentation: Expelling Waste Through Urine
The final stage is augmentation, where waste molecules that are no longer needed by the body are expelled. This occurs as the urine flows through the collective tubules of the kidney, passes into the ureter, then reaches the bladder (vesica urinaria), and is finally excreted through the urethra. This process ensures the removal of excess waste, maintaining fluid balance and homeostasis in the body.
🛑 Conclusion: The Importance of Kidney Health
In conclusion, Azi wraps up the discussion by summarizing the three stages of urine formation and the importance of kidney function. The journey of urine formation may seem complex, but it is vital for filtering and expelling waste. Azi reminds viewers to take care of their kidneys and bids farewell until the next video.

Highlights
The process of urine formation occurs in each nephron of the kidneys.
Urine formation involves three main stages: filtration, reabsorption, and augmentation.
The kidneys act as the body's waste processing plant by filtering toxins from the blood.
Filtration is the first step in urine formation, occurring in the glomerulus, a bundle of porous capillaries.
The glomerulus filters water, salts, glucose, urea, and other small molecules, but retains larger molecules like blood cells and proteins.
The filtrate collected in Bowman's capsule is called glomerular filtrate or primary urine.
Normally, the kidneys produce around 125 cc of filtrate per minute.
Reabsorption is the second stage, where useful substances in the primary urine, such as glucose, salts, amino acids, and water, are reabsorbed back into the blood.
Reabsorption occurs as the filtrate passes through the tubules surrounded by nephrons.
Augmentation is the third step, where waste molecules are removed from the blood and filtered by the kidneys to maintain fluid homeostasis.
Urine is carried from the kidneys through the ureters to the urinary bladder.
The final stage of urine elimination occurs through the urethra, which is part of the reproductive system.
The video emphasizes the importance of keeping the kidneys healthy to support proper urine formation.
The journey of urine formation is more complex and detailed than most people realize.
The speaker encourages viewers to take care of their kidney health.

I Max Hi everyone Welcome to my video
kembali lagi di video saya Azi Oktaviani
kali ini kita akan membahas tentang
proses pembentukan urine Oh ya proses
pembentukan urine terjadi di tiap-tiap
nefron pada ginjal proses ini meliputi
filtrasi atau penyaringan reabsorpsi
atau penyerapan kembali dan augmentasi
Hai yang perlu kita ketahui guys Organ
utama sistem kemih kita adalah ginjal
atau pabrik pengolahan limbah tubuh kita
gunanya untuk menyaring racun keluar
dari tubuh kita Oke kita masuk ketahap
yang pertama yaitu filtrasi atau
penyaringan
Hai filtrasi merupakan langkah pertama
dalam proses pembentukan urine dua
faktor utama yang memungkinkan
terjadinya filtrasi adalah struktur
glomerulus atau kumpulan kapiler darah
yang sangat berpori dan tekanan darah di
glomerulus yang jauh lebih tinggi
dibanding dengan tekanan di
kapiler-kapiler tubuh lainnya dalam
proses filtrasi ini darah dalam
glomerulus yang mengandung air garam
gula Urea dan zat-zat lain akan melewati
Polri glomerulus kecuali yang bermolekul
besar seperti sel darah merah dan
protein hasil penyaringan atau filtrasi
ditampung dalam kapsul Bowman dan
disebut Filtrat glomerulus atau Urine
primer Oh ya dalam keadaan normal akan
diproduksi 125 cc per menit cairan
Filtrat dari kedua ginjal
Hai Wah hebat banget ya yuk kita kenali
tahap yang kedua yaitu reabsorpsi atau
penyerapan kembali reabsorpsi ini
merupakan proses penyerapan kembali
zat-zat yang masih berguna yang terdapat
pada urine primer Filtrat glomerulus
atau Urine primer yang dihasilkan dari
proses filtrasi masih mengandung
bahan-bahan yang berguna bagi tubuh loh
contohnya ada glukosa garam-garam asam
amino dan air oleh karena itu
bahan-bahan tersebut harus diserap
kembali ke dalam darah untuk dapat
digunakan oleh tubuh proses reabsorpsi
terjadi selama Filtrat melalui tubulus
yang dikelilingi oleh nefron
Hai tahap yang ketiga yaitu augmentasi
atau pengeluaran zat ekskresi urin
diperlukan untuk membuang
molekul-molekul sisa dalam darah yang
tidak lagi dipakai dan disaring oleh
ginjal untuk menjaga homeostasis cairan
tubuh proses jalannya pengeluaran urine
dalam tubulus kolektivus yang berada
dalam ginjal Diteruskan oleh ureter
menuju vesika urinaria dan terakhir
adalah organ uretra dalam alat kelamin
nah kira-kira seperti itu proses
pembentukan urine yang terjadi pada
tubuh kita gimana guys ternyata panjang
ya perjalanannya
hai hai
Hai Cukup sekian pembahasan kita kali
ini Terima kasih jaga kesehatan ginjalmu
ya sampai jumpa di video selanjutnya
