Animal Physiology: Circulation and Excretion
There is increase in blood urea when there is insufficient filtration in
The bunch of capillaries present in the Bowman's capsule are called
The glomerulus is a network of capillaries known as a tuft, located at the beginning of a nephron in the kidney. The blood is filtered across the capillary walls of this tuft through the glomerular filtration barrier, which yields its filtrate of water and soluble substances into Bowman's capsule. The filtrate then enters the renal tubule, of the nephron.
So, the correct option is 'glomerulus'.
There is increase in blood urea when there is insufficient filtration in
Which part of the nephron is impermeable to water?
A loop of capillary running parallel to the Henle's loop is known as
Compare the functioning of alveoli in the lungs and nephrons in the kidneys with respect to their structure and functioning.
Mark the wrong match from the following:
Which of the following statements is correct?
All Bowman's capsules of the kidney are found in
Statement 1: Small amount of urea enters the thick segment of Henle's loop which is transported back to interstitium by collecting tubules. Statement 2: Collecting tubules and the thick segment of Henle's loop are permeable to urea.
Select the correct statement.
Read the given statements regarding the human excretory system and select the correct ones. (i) Presence of glucose in urine is known as uremia. (ii) Distal convoluted tubule (DCT) selectively secretes hydrogen ions, ammonia and potassium ions into the filtrate. (iii) Macula densa formed bye cellular modifications in the distal convoluted tubule and the afferent arteriole at their contact location. (iv) Atrial natriuretic factor (ANF) can cause vasoconstriction when blood flow is low to the atria of the heart.
