The kidneys are bean shaped organs, which help the body produce urine to get rid of unwanted waste substances. When urine is formed, tubes called ureters transport it to the urinary bladder, where it is stored and excreted via the urethra.

What else can I help you with?
Is peritubular fluid is same with interstitial fluid?
Peritubular fluid refers specifically to the fluid found in the renal tubules of the kidney, while interstitial fluid is found in the spaces surrounding cells throughout the body, including the kidney. While they both play a role in transporting substances and maintaining homeostasis, they are located in different anatomical compartments.
What is the effect of ANP in the distal tubule?
Atrial natriuretic peptide (ANP) acts on the distal tubule of the kidney to inhibit sodium reabsorption and increase sodium excretion. This leads to increased urine production and ultimately helps regulate blood pressure and fluid balance in the body.
What are the parts of the proximal tubule?
The parts of the proximal tubule in the nephron are the proximal convoluted tubule (PCT) and the proximal straight tubule (PST). The PCT is the first segment after the Bowman's capsule and is responsible for reabsorbing nutrients, ions, and water. The PST continues the reabsorption process and plays a role in maintaining the body's fluid and electrolyte balance.
What does pct reabsorb?
The proximal convoluted tubule (PCT) in the kidney reabsorbs nutrients such as glucose, amino acids, and ions like sodium and chloride. It also reabsorbs water to adjust the body's fluid balance.
What is that bundles that filter waste from blood?
The bundles that filter waste from blood are called nephrons, which are the functional units of the kidneys. Each kidney contains approximately one million nephrons, which consist of a glomerulus and a renal tubule. The glomerulus filters blood, allowing waste products and excess substances to pass into the tubule, where they are further processed to form urine. This filtration process is crucial for maintaining the body's fluid and electrolyte balance.
What organelle is abundant in kidney tububle cells?
Mitochondria are abundant in kidney tubule cells due to their high energy demands for active transport and metabolic processes involved in regulating fluid and electrolyte balance. Mitochondria generate ATP through aerobic respiration to fuel these energy-demanding cellular functions in kidney tubule cells.
What is the function of the nephrons in the excretory process?
The nephron is the functional unit of the kidney, responsible for the actual purification and filtration of the blood. About five thousand nephrons are in each kidney, and each one consists of a renal corpuscle and a renal tubule which carry out the functions of the nephron. The renal tubule consists of the convoluted tubule and the loop of Heinle.
Is peritubular fluid is same with interstitial fluid?
Peritubular fluid refers specifically to the fluid found in the renal tubules of the kidney, while interstitial fluid is found in the spaces surrounding cells throughout the body, including the kidney. While they both play a role in transporting substances and maintaining homeostasis, they are located in different anatomical compartments.
What are nephrons made up of?
Each one consists of a renal corpuscle and a renal tubule which carry out the functions of the nephron. The renal tubule consists of the convoluted tubule and the loop of Heinle http://coe.fgcu.edu/Faculty/GreeneP/kidney/nephron.html.

The PST continues the reabsorption process and plays a role in maintaining the body's fluid and electrolyte balance.
What fluid passes through the renal tubule?
A renal tubule passes most of the fluids it processes into the bloodstream
Where does glucose reabsorption occur in the nephron?
Glucose reabsorption takes place in the proximal renal tubule. This tubule is a portion of the nephron that contains fluid. The functions of the nephron include the reabsorption and secretion of various substances like ions, glucose, and amino acids.
The Macula Densa cells respond to what?
The Macula Densa cells in the kidney respond mainly to changes in the sodium chloride (NaCl) concentration in the tubular fluid. They help regulate the body's blood pressure and fluid balance by sensing NaCl levels and signaling for adjustments in kidney function.
What does pct reabsorb?
The proximal convoluted tubule (PCT) in the kidney reabsorbs nutrients such as glucose, amino acids, and ions like sodium and chloride. It also reabsorbs water to adjust the body's fluid balance.

How do you describe a nephron?
A nephron is the functional unit of the kidney responsible for filtering blood and producing urine. It consists of a glomerulus, Bowman's capsule, proximal tubule, loop of Henle, and distal tubule. Nephrons play a crucial role in regulating electrolyte balance, fluid volume, and maintaining overall homeostasis in the body.
