In human excretory system :i. kidneys and ureters are paired structure...
Both the statements are correct
kidney and ureter are paired structure whereas urinary bladder is a single structure
and kidneys typically extend from T12 to L3, although the right kidney is often situated slightly lower due to the presence of the liver. Each kidney is approximately three vertebrae in length.
In human excretory system :i. kidneys and ureters are paired structure...
Explanation:
- The human excretory system consists of several organs, including the kidneys, ureters, and urinary bladder. These organs work together to remove waste products from the body and maintain fluid balance.
i. kidneys and ureters are paired structures but urinary bladder is single:
- The kidneys are a pair of bean-shaped organs located in the back of the abdominal cavity, one on each side of the spine. They are responsible for filtering waste products from the blood and producing urine. Each kidney is connected to the urinary bladder by a tube called the ureter.
- The ureters are paired tubes that transport urine from the kidneys to the urinary bladder. There is one ureter connected to each kidney.
- The urinary bladder, on the other hand, is a single organ that stores urine until it is expelled from the body. It is located in the pelvic cavity.
ii. Kidneys are situated between the levels of the last thoracic and third lumbar vertebra:
- The position of the kidneys within the body is important for their functioning. The kidneys are situated in the retroperitoneal space, which means they are located behind the peritoneum (the lining of the abdominal cavity) and against the back muscles.
- The kidneys are positioned between the last thoracic and third lumbar vertebrae of the spine. This places them in the lower part of the back, just above the waist.
Conclusion:
- Based on the above explanation, it is clear that both statements i and ii are correct.
- The kidneys and ureters are paired structures, while the urinary bladder is a single organ.
- The kidneys are situated between the levels of the last thoracic and third lumbar vertebrae.
