Which of the following is the anatomical structure of the kidney located immediately before the ureter?
Minor calyx
Renal pyramid
Major calyx
Renal pelvis
The Correct Answer is D
A. The minor calyx collects urine from the renal papillae (tips of the renal pyramids), but it is not the structure immediately before the ureter. It connects to the major calyx.
B. Renal pyramids are structures within the kidney that contain the renal tubules and are involved in the filtration and excretion process. However, they do not directly connect to the ureter.
C. The major calyx is a larger collecting area formed by the union of several minor calyces. It channels urine into the renal pelvis but is not directly before the ureter.
D. The renal pelvis is the funnel-shaped structure that collects urine from the major calyces and funnels it into the ureter. It is the anatomical structure immediately before the ureter, which then carries urine to the bladder.

B. Elevated cholesterol levels may result from metabolic conditions, but they are not a primary consequence of pancreatic dysfunction.
C. Elevated blood sugar is a primary result of pancreatic dysfunction, especially in cases like diabetes mellitus, where the pancreas does not produce enough insulin or the body becomes resistant to insulin.
D. Suppressed immune system is not a direct result of pancreatic dysfunction. However, chronic conditions such as diabetes can affect immune function over time, but it is not the primary effect.
Correct Answer is A
Explanation
A. Dense regular connective tissue consists of fibroblasts arranged tightly between parallel arrays of collagen fibers. This structure provides tensile strength in one direction, which is found in tendons and ligaments.
B. Dense irregular connective tissue also contains collagen fibers, but these fibers are arranged in an irregular, non-parallel pattern, allowing the tissue to withstand tension from multiple directions, such as in the dermis of the skin.
C. Elastic connective tissue contains a higher proportion of elastin fibers, which provide stretch and recoil. It is found in structures like the walls of large arteries, but not in parallel arrays of collagen fibers.
D. Reticular connective tissue consists of a network of thin, branching collagen fibers, providing structural support in organs like the spleen and lymph nodes, but it does not have tightly packed fibroblasts between parallel collagen fibers.
