Which structure conducts urine from the kidney to the urinary bladder?
Ureter
Urethra
Renal column
Renal pelvis
The Correct Answer is A
The ureters are long, narrow tubes that transport urine from the kidneys to the urinary bladder. Each kidney has one ureter, which emerges from the renal pelvis (a funnel-shaped cavity in the kidney) and descends downward, passing behind the peritoneum and along the back of the abdominal cavity. The ureters then enter the bladder through small openings at the base of the bladder, where they join with the urethra, a tube that carries urine out of the body.

Correct Answer is C
Explanation
Blood then carries them to target cells or organs throughout the body. Hormones are chemical messengers that help to regulate various physiological processes such as growth, metabolism, and reproduction. Unlike exocrine glands (option a), which secrete their products into ducts that carry them to external surfaces such as the skin or digestive tract, endocrine glands have no ducts and release their secretions directly into the circulatory system. Salivary glands (option d) are exocrine glands that secrete saliva into ducts leading to the mouth. Option b is also incorrect as it does not accurately describe endocrine glands.
Correct Answer is D
Explanation
A ball and socket joint is a type of synovial joint where the rounded head of one bone fits into the concave socket of another bone, allowing movement in multiple directions. The shoulder joint is a classic example of a ball and socket joint, where the rounded head of the humerus bone fits into the shallow socket of the scapula bone, allowing for a wide range of movements such as flexion, extension, abduction, adduction, and rotation. The ankle joint is a hinge joint, the elbow joint is a hinge joint, and the knee joint is a complex hinge joint.
