Urinary Flashcards
What is the primary function of the kidneys?
Processing and excreting body fluids
This includes filtering blood and producing urine.
What are the primary organs involved in fluid processing in the body?
Kidneys
The kidneys are essential for filtering blood and forming urine.
What is urine?
Waste that is not reabsorbed
Urine consists of substances that the body does not need, which are excreted.
What is the role of blood vessels in relation to the kidneys?
Bring blood to and from the kidneys
Blood vessels play a crucial role in kidney function by supplying blood for filtration.
What are the structural and functional units of the kidneys?
Microscopic nephrons
Nephrons are the basic working units of the kidney that filter blood.
What are the two major regions of the kidney?
- Renal Cortex
- Renal Medulla
These regions have distinct roles in the kidney’s function.
What surrounds the renal medulla?
Renal Cortex
The renal cortex is the outer region of the kidney.
What is contained in the renal cortex?
Glomerulus of the nephron
The glomerulus is a network of capillaries involved in filtration.
What is the glomerulus?
Network of capillaries
It plays a key role in filtering blood in the kidneys.
What does blood pressure do in the glomerulus?
Pushes water, salt, glucose, amino acids, and urea from blood
This process is essential for filtration in the kidneys.
What is filtrate?
Material leaving the blood through walls of glomerular capillaries
Filtrate contains substances that are processed to form urine.
What collects the filtrate in the nephron?
Bowman’s Capsule
Bowman’s Capsule surrounds the glomerulus and collects the filtered material.
Where is Bowman’s Capsule located?
Surrounds the glomerulus
It is the first part of the nephron where filtration occurs.
What occurs in the proximal tubule of the nephron?
Glucose is reabsorbed back into blood
This reabsorption is vital for maintaining energy levels in the body.
What is tubular reabsorption?
Movement of filtrate back into bloodstream
This process ensures that essential substances are not lost in urine.
