Describe the excretory system of man giving the structure of a nephron?
Understand the Problem
The question is asking for descriptions of biological systems: the excretory system in men, including the structure of a nephron, and the female reproductive system with a labeled diagram. This requires knowledge of human anatomy and physiology.
Answer
The human excretory system comprises kidneys, ureters, bladder, and urethra. Nephrons, the filtration units, consist of a glomerulus and renal tubule.
The human excretory system includes two kidneys, two ureters, a urinary bladder, and a urethra. Each kidney contains numerous nephrons, the functional units which filter blood. A nephron consists of a glomerulus (a cluster of capillaries) and a renal tubule. Blood is filtered in the glomerulus, and the renal tubule processes the filtrate into urine.

A nephron consists of a glomerulus (a cluster of capillaries) and a renal tubule. Blood is filtered in the glomerulus, and the renal tubule processes the filtrate into urine.
More Information
Nephrons are located in the renal cortex of each kidney. They perform filtration, reabsorption, and secretion, which are essential for maintaining body fluid balance.
Tips
A common mistake is confusing the renal artery and vein with the glomerulus. Remember that the glomerulus is part of the nephron within the renal cortex.
