Question 11 Mark
Arrange and Rewrite :
Loop of Henle, Distal convoluted tubule, Bowman's Capsule, Proximal convoluted tubule.
Answer
Proximal Convoluted Tubule $\rightarrow$ reabsorption of nutrients $\rightarrow$ Loop of Henle $\rightarrow$ distal convoluted tubule $\rightarrow$ secretion of wastes
Explanation:
Bowman's capsule, Proximal convoluted tubule, Loop of Henley, Distal convoluted tubule: This is the sequence of parts of nephron in sequence as the filtrate passes through.

Question 101 Mark
Arrange and Rewrite :
Reabsorption in the renal tubules $\rightarrow$ Excretion through the urethra $\rightarrow$ Filtration in the kidneys $\rightarrow$ Urine storage in the bladder
Answer
Filtration in the kidneys $\rightarrow$ Reabsorption in the renal tubules $\rightarrow$ Urine storage in the bladder $\rightarrow$ Excretion through the urethra
Explanation:
The first step is filtration in the kidneys, where waste and excess substances are filtered from the blood. The filtrate then moves to the renal tubules, where reabsorption of water and necessary solutes occurs. The resulting urine is stored in the bladder before finally being excreted through the urethra.

Question 111 Mark
Arrange and Rewrite :
Filtration in glomerulus $\rightarrow$ Blood Plasma $\rightarrow$ Addition of wastes $\rightarrow$ reabsorption in tubules $\rightarrow$ Formation of urine
Answer
Blood Plasma $\rightarrow$ filtration in glomerulus $\rightarrow$ reabsorption in tubules $\rightarrow$ addition of wastes $\rightarrow$ formation of urine
Explanation:
Blood plasma is first filtered in the glomerulus. Then, as it moves through the tubules of the nephron, essential substances are reabsorbed, and wastes are added, leading to the formation of urine.

Question 121 Mark
Arrange and Rewrite :
Evaporation from skin surface $\rightarrow$ Sweat Gland Secretion $\rightarrow$ Sweat duct transport $\rightarrow$ Sweat pore opening
Answer
Sweat Gland Secretion $\rightarrow$ Sweat duct transport $\rightarrow$ Sweat pore opening $\rightarrow$ Evaporation from skin surface
Explanation:
The sequence begins with the secretion of sweat by the sweat glands, followed by its transport through sweat ducts. The sweat then reaches the skin surface via sweat pore openings, and finally, it evaporates from the skin surface, aiding in thermoregulation and waste excretion.

Question 131 Mark
Arrange and Rewrite :
Tubular secretion in the distal convoluted tubule $\rightarrow$ Selective reabsorption in the proximal convoluted tubule $\rightarrow$ Concentration of urine in the collecting duct $\rightarrow$ Filtrate formation in Bowman's capsule
Answer
Filtrate formation in Bowman's capsule $\rightarrow$ Selective reabsorption in the proximal convoluted tubule $\rightarrow$ Tubular secretion in the distal convoluted tubule $\rightarrow$ Concentration of urine in the collecting duct
Explanation:
The process starts with filtrate formation in Bowman's capsule, followed by selective reabsorption in the proximal convoluted tubule. Next, the distal convoluted tubule conducts tubular secretion, adding waste to the filtrate. Finally, the collecting duct concentrates urine, determining its final volume and concentration.

Question 141 Mark
Arrange and Rewrite :
Urinary bladder $\rightarrow$ Urethra $\rightarrow$ Kidneys $\rightarrow$ Ureters $\rightarrow$ Nephrons
Answer
Nephrons $\rightarrow$ Kidneys $\rightarrow$ Ureters $\rightarrow$ Urinary bladder $\rightarrow$ Urethra
Explanation:
The sequence starts with Nephrons, where urine formation occurs. It then flows to the Kidneys for further processing. From there, urine moves through the Ureters to the Urinary bladder for storage, and finally, it is expelled via the Urethra.

Question 151 Mark
Arrange and Rewrite :
Reabsorption of nutrients $\rightarrow$ distal convoluted tubule $\rightarrow$ Loop of Henle $\rightarrow$ Proximal Convoluted Tubule $\rightarrow$ secretion of wastes
Answer
Proximal Convoluted Tubule $\rightarrow$ reabsorption of nutrients $\rightarrow$ Loop of Henle $\rightarrow$ distal convoluted tubule $\rightarrow$ secretion of wastes
Explanation:
In the Proximal Convoluted Tubule, essential nutrients are reabsorbed. The Loop of Henle continues this process, while in the distal convoluted tubule, additional wastes are secreted, refining the composition of urine.

Question 161 Mark
Arrange and Rewrite :
Glomerulus $\rightarrow$ filtration of blood $\rightarrow$ Malpighian Capsule $\rightarrow$ formation of glomerular filtrate $\rightarrow$ Bowman's capsule
Answer
Malpighian Capsule $\rightarrow$ Bowman's capsule $\rightarrow$ glomerulus $\rightarrow$ filtration of blood $\rightarrow$ formation of glomerular filtrate
Explanation:
The Malpighian Capsule, which includes Bowman's capsule, encloses the glomerulus. The glomerulus filters blood, and the filtration process results in the formation of glomerular filtrate within the Bowman's capsule.
