The Correct Answer is D
Trabeculae: These are thin connective tissue strands that extend from the capsule of the lymph node into the interior. They help to divide the lymph node into distinct compartments or regions, which include the cortex (outer area) and medulla (inner area). This compartmentalization is important for the organization and function of the lymph node, allowing it to efficiently filter lymph and facilitate the immune response.

Correct Answer is C
Explanation
A. Parietal Cell: Parietal cells are responsible for secreting hydrochloric acid (HCl) and intrinsic factor, not pepsinogen. HCl activates pepsinogen into pepsin.
B. Mucous Neck Cell: Mucous neck cells secrete mucus to protect the gastric lining but do not secrete pepsinogen.
C. Chief Cell: Chief cells (also known as zymogenic cells) are specialized cells in the stomach that secrete pepsinogen, the inactive precursor of the digestive enzyme pepsin.
D. Enteroendocrine Cell: Enteroendocrine cells secrete hormones like gastrin, which regulates digestive processes, but they do not secrete pepsinogen.
Correct Answer is A
Explanation
A. Urinary Bladder: The urinary bladder is composed of smooth muscle, including the detrusor muscle, which contracts to expel urine during urination. The detrusor muscle allows the bladder to stretch as it fills with urine and contract when it's time to empty.
B. Ureter: The ureters are muscular tubes that transport urine from the kidneys to the bladder but do not contain detrusor muscle. They have a different type of smooth muscle that aids in peristalsis.
C. Renal Artery: The renal artery is a blood vessel that supplies blood to the kidneys and does not contain muscle tissue like the detrusor muscle.
D. Kidney: The kidneys are organs that filter blood to produce urine but do not contain detrusor muscle. They consist mainly of nephron structures for filtration and reabsorption.
