Excretory products and their elimination practice · Mixed difficulty

The living steady state has a self-regulatory mechanism which is known as

Marine teleost fishes excrete

Metabolic wastes containing nitrogen in our body are due to

Choose the correct option from given statement I. Glomerular filtrationrate is 125 mL/min II. Ultrafiltration is opposed by colloidal osmotic pressure of plasma III. Tubular secretion takes place in loop in Henle IV. Tubular secretion takes place in glomerulus V. Aldosterone induces greater sodium reabsorption . The correct option is

The waste products produced in man which need excretion are?

Assertion: Uraemia is harmful condition
Reason: Uraemia may lead to kidney failure

Which one of the following statements is correct with respect to kidney function regulation?

All Bowman’s capsules of the kidney are found in

Creatinine is a nitrogenous waste, formed during
muscular activity. If ‘X’ amount of creatinine is
present in blood but its amount in urine is greater
than X. Which of the steps of urine formation
does it undergo?

(a) Ultrafiltration

(b) Selective reabsorption

(c) Tubular secretion

Which of the following features activates the JG cells?  I. Fall in GBR,  II. Fall in GBF,  III. Fall in GFR.  Choose the correct option

Due to insufficient filtration in the Bowman's capsule, all are likely to happen except:

Assertion: PCT reabsorbs 70 – 80% electrolytes & water
Reason: PCT is lined with brush bordered cuboidal epithelium

The neural mechanism of micturition is called

Vasa recta is minute vessel of Peritubular capillaries network, which is

The outline of principal event of urination is given below in unorder manne :  I. Stretch receptors on the wall of urinary bladder send signal to the CNS,  II. The bladder fills with urine and becomes distended,  III. Micturition, IV. CNS passes on motor messenger to initiate the contraction smooth muscles of bladder and simultaneous relaxation of urethral sphincter. The correct order of steps for urination is

Green glands present in some arthropods help in

Which one of the following correctly explains the function of a specific part of a human nephron?

If Henle’s loop were absent from mammalian nephron, which of the following is to be expected?

I. Reabsorption of water occurs passively in the initial segment of nephron,  II. Nitrogenous waste are absorbed by active transport,  III. Conditional reabsorption of $N{a^ + }$ and water takes place in DCT,  IV. DCT reabsorbs glucose,  V. DCT is capable of selective secretion of ${H^ + }$,${K^ + }$ and $N{H_3}$ to maintain pH and $N{a^ + }$ - ${K^ + }$ balance in blood, VI. Substances like glucose, amino acids, $N{a^ + }$, etc, in the filtrate are reabsorbed actively.   Choose the option with incorrect statements

Select the right option

How many layers do filtration membrane consist of

Which of the following is uricotelic

Complete the analogy. Increases blood pressure : Renin :: Decreases blood pressure : ________

Excretion means

ADH is also called

Assertion: Filtration is a selective process performed by the glomerulus using the glomerular capillary blood
pressure.
Reason: Blood is filtered through fine pores present in PCT

Juxta glomerular apparatus is modification in the

The first step in urine formation is the filtration of blood which is carried out by the

Malpighian tubules are the excretory structures of

Assertion: Urine produced (1 to 1.5 L) per day is far less than the volume of filtrate occur per day (180 L)
Reason: 99% of filtrate is reabsorbed by the renal tubules
