During a biology class, the teacher asked the students, 'Where are the kidneys located in the human body?'

• Between the first and second lumbar vertebra

• Between the second and third thoracic vertebra

• Between the last thoracic to third lumbar vertebra

• Between the third and fourth lumbar vertebra

Answer explanation

The kidneys are located between the last thoracic and third lumbar vertebra. This is the correct choice.

What are the dimensions of the kidney?

• Length – 5cm, Breath- 3cm, Thickness- 2cm

• Length – 10cm, Breath- 5cm, Thickness- 4cm

• Length – 15cm, Breath- 7cm, Thickness- 5cm

• Length – 8cm, Breath- 4cm, Thickness- 3cm

Answer explanation

The dimensions of the kidney are Length – 10cm, Breath- 5cm, Thickness- 4cm. This is the correct choice.

What are the histological components of the kidney?

• Outer layer and inner layer

• Outer cortex and inner medulla

• Outer tissue and inner tissue

• Outer membrane and inner membrane

Answer explanation

The histological components of the kidney are the outer cortex and inner medulla. These components are responsible for the filtration and reabsorption of waste products and the production of urine.

During a biology class, the teacher asked the students, 'From where does the kidney receive blood?' What would be the correct answer?

• Renal vein

• Pulmonary artery

• Renal artery
