Animal Physiology: Circulation and Excretion
There is increase in blood urea when there is insufficient filtration in
All Bowman's capsules of the kidney are found in
Bowman's capsule is a cup-like sack at the beginning of the tubular component of a nephron. A glomerulus is enclosed in the sac. Fluids from blood in the glomerulus are collected in the Bowman's capsule (i.e., glomerular filtrate) and further processed along the nephron to form urine. This process is known as ultrafiltration. All glomeruli are located in the renal cortex.
Thus, the correct answer is 'cortex.'
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:
The bunch of capillaries present in the Bowman's capsule are called
Which of the following statements is correct?
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.
