Question

How does filtration occur during the formation of urine?
A. Pressure causes water and dissolved substances to filter through capillary walls of the glomerulus.
B. Nephron tubes filter waste products and transfer them into the collecting tubules.
C. Bowman's capsules collect dissolved substances and transfer them to the peritubular capillaries.
D. Gravity forces large particles to filter through capillary walls of the glomerulus.
Don't Give Me Straight Answer Please Explain.
Thank You;)

Answer 1

Waste Ions and Hydrogen Ions Secreted from the Blood Complete the Formation of Urine. The filtrate absorbed inthe glomerulus flows through the renal tubule, where nutrients and water are reabsorbed into capillaries. ... This process iscalled secretion.

Answer 2

Answer:

Nephron tubes filter waste products and transfer them into the collecting tubules is the correct answer.

Explanation:

• The process of making urine starts when blood enters the kidneys to support filtration, reabsorption, and secretion.
• The glomerulus in the kidney filters the material, which is then transported through Bowman's capsule. The afferent arteriole allows filtrate, also known as pre-pre pee, to reach the kidney.
• Reabsorption is in charge of drawing molecules, ions, and water from the glomerulus and returning them to the bloodstream.
• The filtrate enters the proximal tubules of the kidney's nephron, travels via the loop of Henle and collecting ducts, and is subsequently transported to the ureter for excretion.
• The proximal tubule reabsorbs salts, vitamins, glucose, and amino acids during the procedure (pre-urine).
• Secretion is the step in urine formation responsible for transferring hydrogen ions, drugs, urea, and creatinine to the collecting duct for removal. The filtrate passes from the peritubular capillaries through the loop of Henle and into the distal tubule. It will then be excreted through the ureters as urine.
• Secretion removes harmful substances from the blood such as potassium ions, hydrogen ions, ammonium ions, urea, certain hormones, and drugs/medications.
• Filtrate and fluid pass through the lumen of a tube or capillary. The lumen refers to the central aspect of the tubular structure. Blood flows within the lumen of an artery or vein.

Hence, option (B) is correct.
