What is true about human kidneys?

The kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, one on each side of your spine. Healthy kidneys filter about a half cup of blood every minute, removing wastes and extra water to make urine.

Which of the following statement about kidney structure and function is true?

Which of the following statements about kidney structure and function is true? Explanation: Cells and large proteins are too large to cross the capillary membranes of the glomerulus, and cannot be filtered into Bowman’s capsule. Finally, each kidney is composed of about one million nephrons.

Which one of the following statements in regard to the excretion by the human kidneys is correct ascending limb of loop of Henle is impermeable to electrolytes?

The descending limb of the loop of Henle is permeable to water but impermeable to electrolytes. The ascending limb is impermeable to water but allows transport of electrolytes. Reabsorption of sodium ions and water takes place in the distal convoluted tubule. Also, it is capable of reabsorption of HCO₃.

Which of the following is correct for human kidney?

It is cylindrical.

Which of the following kidney function is not true?

Option D: Kidneys are not involved in secretion of antibiotics. Antibiotics are basically a range of medicines which are used to inhibit the growth and also kill microorganisms. Therefore, this is the incorrect option. Thus, the correct option is A) Regulation of blood pressure.

Which one of the following statements in Regardto the excretion by the human kidneys is correct?

S0, the correct answer is ‘Option B’.

Which of the following statement is correct regarding urine formation?

So, the correct answer is ‘To prevent diuresis, ADH facilitates water reabsorption from the later parts of the tubule’.

Is structural and functional units of kidney?

Nephron, functional unit of the kidney, the structure that actually produces urine in the process of removing waste and excess substances from the blood. There are about 1,000,000 nephrons in each human kidney.

What is the functional unit of kidneys?

The functional unit of the kidney is called the nephron. It comprises of a coiled renal tubule and a vascular network of peritubular capillaries. The tubule consists of different regions, each with their own important function.

Which of the following is not reabsorbed by kidney?

Sodium is actively pumped out, while potassium and chloride diffuse down their electrochemical gradients through channels in the tubule wall and into the bloodstream. The walls of the thick ascending limb are impermeable to water, so in this section of the nephron water is not reabsorbed along with sodium.

Which statement is correct about the function of the renal tubule?

Question : Identily the correct statements wrt to functions of renal tubules. “Identily the correct statements wrt to functions of renal tubules.” All essential nutrients, 70-80% of electrolyses and water-prosimal convoluted tobules. Maintenance of high osmolarity of the medullary intestinal fluid-Collecting Duct.

Which is not a correct statement regarding nephron?

Answer: option B) is not correct b’coz cortical nephrons have Vasa recta.

Why is it called ultrafiltration?

-The process of glomerular filtration is known as ultrafiltration because blood is filtered very finely through all the membranes such that all the components of the blood plasma are passed on except proteins.
