The urinary system contributes to homeostasis through several roles which include: (Select all that apply)
A. Final synthesis step of vitamin K production
Final synthesis step of vitamin K production: The final (and major) synthesis of vitamin K is by gut bacteria and liver processes; the urinary system (kidneys) is not the final synthesis site for vitamin K .
B. Filters the blood, removing wastes
Filters the blood, removing wastes: The kidneys filter blood plasma (glomerular filtration) to remove metabolic wastes and excess substances .
C. Regulates the pH of the body
Regulates the pH of the body: The kidneys conserve or excrete H⁺ and bicarbonate and so play a central role in acid–base balance .
D. Excretion of wastes
Excretion of wastes: By forming urine and eliminating nitrogenous wastes and excess electrolytes/fluid, the urinary system excretes metabolic wastes .

Similar Questions
Select the structures that are part of the larynx. (Select all that apply)
A. Vocal cords
Vocal cords: The vocal cords (vocal folds) are mucosal folds that lie within the larynx and produce sound when they vibrate
B. Thyroid cartilage
Thyroid cartilage: The thyroid cartilage is the largest laryngeal cartilage (forms the “Adam’s apple”) and provides structural support to the larynx
C. Cricoid cartilage
Cricoid cartilage: The cricoid cartilage is a complete ring of cartilage inferior to the thyroid cartilage that forms part of the laryngeal skeleton
D. Laryngopharynx
Laryngopharynx: The laryngopharynx is the lower part of the pharynx (shared passageway for food and air) that lies posterior to the larynx; it is pharyngeal tissue, not a structural component of the larynx itself
E. Epiglottis
Epiglottis: The epiglottis is a flap of elastic cartilage attached to the entrance of the larynx that prevents aspiration during swallowing
F. C- rings
C-rings: “C-rings” typically refer to the incomplete C-shaped cartilaginous rings of the trachea, not the larynx

The
Full Explanation
A. Gallbladder: The gallbladder stores and releases bile into the duodenum via the common bile duct when stimulated (e.g., by CCK). It does release a secretion into the duodenum, but it primarily stores bile produced by the liver.
B. Liver: The liver produces bile, which drains via hepatic ducts into the common bile duct and empties into the duodenum -the liver is a primary secretor whose products reach the duodenum.
C. Spleen: The spleen is a lymphoid/hematologic organ (filters blood, immune functions) and does not release digestive secretions into the duodenum.
D. Gastric glands: Gastric glands secrete gastric juice into the stomach lumen (not the duodenum), so they do not release secretions into the duodenum.
E. Pancreas: The exocrine pancreas secretes digestive enzymes and bicarbonate into the duodenum via the pancreatic duct.
F. Intestinal glands: Intestinal glands (crypts of Lieberkühn) secrete intestinal juice directly into the intestinal lumen (including the duodenum), but the most commonly tested paired organs that "release secretions into the duodenum" are the liver (bile) and pancreas (pancreatic juice).
Which test helps in the early detection of cervical cancer?
A. Pap Smear
Pap Smear: The Papanicolaou (Pap) smear screens cervical cells for precancerous changes (dysplasia) and is the standard test for early detection of cervical cancer.
B. BRCA test
BRCA test: BRCA genetic tests assess hereditary breast/ovarian cancer risk (BRCA1/2), not cervical cancer screening.
C. ELISA test
ELISA test: ELISA is a lab technique for detecting antibodies/antigens (used in many contexts, e.g., HIV testing) but is not a routine screening test for cervical cancer.
D. Mammogram
Mammogram: A mammogram is an imaging test used to screen for breast cancer, not cervical cancer.
