Short questions
Q1.State any two functions of the human kidneys.
Q2.What is a nephron? Why is it called the functional unit of the kidney?
Q3.Differentiate between the renal artery and the renal vein.
Q4.During a school sports event, a student sweats heavily and drinks very little water. Explain how the kidneys help maintain water balance in this situation.
Q5.Name the main parts of the human excretory system and state the function of each.
Q6.Why is it important for the kidneys to continuously filter blood?
Q1.Describe the structure of the human kidney. Explain the location of the kidneys and the arrangement of the cortex, medulla, renal pelvis, and associated blood vessels.
Q2. Explain the structure of a nephron with the help of a labelled diagram. Mention the functions of its major parts.
Q3. A doctor advises people to drink enough clean water and avoid excessive consumption of junk food and soft drinks. Explain how these healthy habits help protect the kidneys and maintain an efficient excretory system.
Q1. Read the following case:
A patient visits a hospital after experiencing swelling in the legs and reduced urine output. The doctor recommends tests to examine kidney function.
Based on your understanding of the human excretory system:
Explain the role of the kidneys in maintaining the internal environment of the body.
Describe how blood reaches and leaves the kidneys.
Discuss why healthy kidneys are essential for normal body function.
Q2. A biology teacher prepares the following flow chart:
Renal Artery → Kidney → Ureter → Urinary Bladder → Urethra
Explain the role of each part shown in the flow chart and describe how they work together in the excretory system.
Q3. Read the following observations:
Blood enters the kidneys continuously.
Waste substances are removed from the blood.
Useful substances are retained in the body.
Urine is transported to the urinary bladder for temporary storage.
Using these observations, explain how the structure of the kidneys and nephrons supports efficient excretion and helps maintain homeostasis.
