Kidney Functions and Filtration
The kidneys perform specialized filtering functions to maintain blood composition. They remove waste products and excess substances while selectively reabsorbing essential molecules.
Highlight: The kidneys' primary function is to filter blood and produce urine, removing waste while preserving useful substances.
Example: Useful substances like specific ions are reabsorbed back into the bloodstream after initial filtration.
Deamination Process
The liver performs deamination to break down excess proteins that cannot be stored in the body. This process is crucial for protein metabolism and waste elimination.
Vocabulary: Deamination is the process of breaking down excess amino acids into ammonia, which is then converted to less toxic urea.
Highlight: The conversion of toxic ammonia to urea is essential as urea can be safely filtered by the kidneys and excreted in urine.
Ion Regulation
Ion balance is crucial for cellular function and is carefully regulated through kidney filtration processes.
Definition: Ions are electrically charged particles that must be maintained at specific concentrations in the blood for proper cell function.
Highlight: While some ions are lost through sweat, the kidneys provide precise regulation of ion levels through selective reabsorption.
Water Balance
Water regulation is essential for cellular health and function, with the kidneys playing a central role in maintaining proper fluid balance.
Example: Cellular damage can occur through crenation or cell lysis when water balance is disturbed.
Highlight: The kidneys regulate water balance through controlled filtration and reabsorption processes.
ADH and Urine Concentration
The concentration of urine is regulated by Anti-Diuretic Hormone , which responds to blood water levels.
Definition: ADH is a hormone produced by the pituitary gland that controls water reabsorption in the kidneys.
Highlight: When blood water levels are high, less ADH is released, resulting in more dilute urine production.
Dialysis Treatment
Dialysis serves as a crucial treatment option for patients with kidney failure, artificially filtering blood to remove waste products.
Definition: Dialysis is a medical procedure that uses a machine to filter blood when kidneys fail to function properly.
Highlight: While dialysis is life-sustaining, it comes with challenges including time commitment, expense, and potential complications.
Kidney Transplantation
Kidney transplantation offers a permanent solution for kidney failure, though it comes with its own set of challenges and considerations.
Highlight: Transplants provide a complete cure for kidney failure but require careful matching and ongoing immunosuppression.
Example: Organs can come from deceased donors on the organ donor register or living relatives who are compatible matches.
The Kidneys: Introduction
The kidneys are vital organs responsible for maintaining homeostasis through waste filtration and regulation of body fluids.
Definition: Kidneys are paired organs that filter blood and produce urine as a means of removing waste products from the body.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
