Question

Two kidneys of human beings lie (a) At the level of ovaries (b) At the same level (c) Left kidney at a higher level than the right one (d) Right kidney at a higher level than the left one

Short answer

The correct answer is (c) Left kidney is at a higher level than the right one.

Step-by-step solution

Understand the question

The first step involves understanding what the question is asking. The question is asking about the positioning of the kidneys in the human body, and giving multiple choices as possible answers.

Recall kidney anatomy

From knowledge of human anatomy, we know that the kidneys are two bean-shaped organs located in the back of the abdomen, on both the left and right side of the body.

Analyzing the options

Given the options, we can rule out 'At the level of ovaries' and 'At the same level', because kidneys are not at the same level as ovaries, and they are also not situated at the same level.

Select the correct answer

Upon comparison, the correct answer is option 'c' which states that the left kidney is at a higher level than the right one. This is corroborated by the fact that the right kidney is slightly lower due to the large size of the liver on the right side of the body.

Key concepts

Understanding Human Anatomy

Grasping the fundamentals of human anatomy is critical for students preparing for medical exams like NEET. A clear concept of the location, structure, and function of organs is foundational knowledge for future medical professionals.
In particular, knowledge of the kidneys, their shape, and positioning is integral. The kidneys are retroperitoneal organs, meaning they are located behind the peritoneum, a lining of the abdominal cavity. Each kidney, resuming a bean-like shape, plays a vital role in functions such as filtering waste products, balancing electrolytes, and regulating blood pressure.

Part of understanding kidney anatomy is recognizing how other organs can affect their position. For instance, the presence of the liver causes the right kidney to sit slightly lower than the left. This precise detail is not just academic trivia—it has practical implications for procedures like kidney transplants, radiological exams, and understanding the pathways of diseases.

Kidney Positioning in the Body

Diving deeper into the anatomy of the kidneys, let's consider their distinct vertical alignment. A common misconception is that both kidneys are symmetrically placed at the same level within the body. However, as we've learned, this is not the case. The right kidney is typically positioned slightly lower than the left one.
This asymmetry is due to the liver, a massive organ occupying substantial space on the right side of the abdominal cavity, pushing the right kidney downward. Moreover, the kidney's location—wrapped by layers of fat and other tissues—helps it stay cushioned within the body, protecting it from physical damage.

Understanding this asymmetry is essential not only for identifying organs in imaging tests but also for aspiring medical students to correctly interpret symptoms and apply their knowledge in clinical practice.

NEET Biology Preparation

For students preparing for the National Eligibility cum Entrance Test (NEET), mastering biology is a major part of the journey. NEET assesses knowledge across a wide range of biological concepts, including human anatomy.
A well-structured study plan emphasizing conceptual clarity can help students excel in biology. Regular revision of key topics, understanding the interrelations between systems, and applying facts to practical scenarios are all vital study strategies. Furthermore, using mnemonic devices to remember specific details like the asymmetrical positioning of the kidneys can be immensely helpful. Visual aids such as diagrams also play a crucial role in retaining complex information. With consistent effort and smart preparation tactics, students can navigate the rigorous NEET syllabus and perform strongly in the biology section of the exam.
