The functional unit of the kidney is [C] Nephron. Nephrons are complex microscopic structures responsible for the filtration of blood and the formation of urine in the kidneys. Each kidney contains millions of nephrons. Each nephron consists of a renal corpuscle, comprising the glomerulus and Bowman’s capsule, and a renal tubule. The renal tubule further includes the proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting duct. Blood is filtered in the renal corpuscle, where waste products and excess substances are removed from the blood and converted into urine.
The renal tubule then processes this filtrate, reabsorbing essential substances such as water, glucose, and electrolytes, and secreting waste products into the urine. The nephron’s intricate structure and physiological functions play a crucial role in maintaining electrolyte balance, regulating blood pressure, and eliminating waste products from the body.
The yellow color of urine is due to the presence of [D] Urochrome. Urochrome, also known as urobilin, is a pigment resulting from the breakdown of hemoglobin during the normal metabolic processes in the liver.

The yellow color of urine is due to the presence of [D] Urochrome. Urochrome, also known as urobilin, is a pigment resulting from the breakdown of hemoglobin during the normal metabolic processes in the liver. After hemoglobin is broken down, bilirubin is produced, which is further processed and excreted in bile. Some of the bilirubin is converted into urobilinogen in the intestines, which is then oxidized by intestinal bacteria to form urochrome.
Urochrome is filtered from the blood by the kidneys and excreted in urine, giving it a yellow color. The intensity of the yellow color can vary depending on factors such as hydration levels, diet, and certain medications. Therefore, the presence of urochrome is responsible for the typical yellow hue observed in urine.
In humans, blood is filtered in [B] Bowman's capsule. Bowman's capsule is a key component of the renal corpuscle, which is part of the nephron, the functional unit of the kidney. Blood enters the glomerulus, a network of capillaries, where filtration occurs under pressure. This filtered fluid, knownRead more
In humans, blood is filtered in [B] Bowman’s capsule. Bowman’s capsule is a key component of the renal corpuscle, which is part of the nephron, the functional unit of the kidney. Blood enters the glomerulus, a network of capillaries, where filtration occurs under pressure. This filtered fluid, known as filtrate, enters Bowman’s capsule. Bowman’s capsule surrounds the glomerulus and collects the filtrate, which then moves through the renal tubules, where reabsorption and secretion processes occur to regulate the composition of urine.
The filtrate eventually exits the nephron and enters the collecting duct system, where further adjustments may be made before the urine is transported to the ureter and subsequently expelled from the body through the urinary bladder. Bowman’s capsule plays a crucial role in the initial filtration step of urine formation, allowing waste products and excess substances to be removed from the blood.
The smallest endocrine gland in the human body is the [C] Pituitary gland.

The smallest endocrine gland in the human body is the [C] Pituitary gland. Despite its small size, the pituitary gland, also known as the master gland, plays a vital role in regulating numerous physiological processes. It is located at the base of the brain, nestled within a bony structure called the sella turcica. Despite its small size, the pituitary gland exerts significant control over the endocrine system by secreting various hormones that regulate growth, reproduction, metabolism, stress response, and other essential functions.
The pituitary gland consists of two main parts: the anterior pituitary (adenohypophysis) and the posterior pituitary (neurohypophysis), each responsible for producing distinct hormones. Despite its diminutive size compared to other endocrine glands like the thyroid or pancreas, the pituitary gland’s regulatory functions are indispensable for maintaining homeostasis and overall health.

Mammals make urea in the [A] Liver. Urea synthesis primarily occurs in the liver as a result of the deamination of amino acids during protein metabolism. The liver contains enzymes necessary for this process, converting ammonia, a toxic byproduct of protein breakdown, into urea, a less toxic compound. Once synthesized, urea is released into the bloodstream and transported to the kidneys for excretion. In the kidneys, urea is filtered out of the blood and excreted in urine, contributing to the body’s waste removal process.
The spleen is primarily involved in immune function and does not play a direct role in urea synthesis. The bladder, often colloquially referred to as a “bag,” is an organ involved in urine storage and does not produce urea but rather temporarily stores urine before elimination from the body.
