Which of the following is the process of voluntary urination?
Reabsorption
Incontinence
Micturition
Filtration
The Correct Answer is C
a. Reabsorption: Reabsorption is the process by which the kidneys reabsorb water and other needed solutes from the filtrate back into the bloodstream.
b. Incontinence: Incontinence is the involuntary loss of urine.
c. Micturition: Micturition is the voluntary process of emptying the urinary bladder. Urine is produced by the kidneys, stored in the bladder, and released through the urethra when the bladder muscles contract and the sphincter relaxes.

Correct Answer is B
Explanation
a: Cerebellum - The cerebellum is responsible for coordination and balance but is not where the medulla, pons, and midbrain are located.
b. Brainstem-The brainstem is composed of the medulla oblongata, pons, and midbrain. It regulates many basic physiological functions such as heart rate, breathing, and sleep.
c: Ventricles - The ventricles are fluid-filled cavities within the brain, not regions containing the medulla, pons, and midbrain.
d: Choroid plexus - The choroid plexus produces cerebrospinal fluid (CSF) within the ventricles of the brain, but it is not where the medulla, pons, and midbrain are located.
Correct Answer is A
Explanation
a. Secretes fluid to reduce friction between layers: This is correct. The pleural membranes secrete pleural fluid, which reduces friction between the visceral and parietal layers during breathing.
b. Secretes a substance that reduces surface tension of alveoli: This describes the function of surfactant, which is secreted by alveolar cells, not pleural membranes.
c. Secretes a substance to keep epithelial cells wet: This is a general description that doesn't specifically apply to pleural membranes.
d. Secretes fluid involved in protection from infections: While pleural fluid may have some protective roles, its primary function is to reduce friction, not directly to protect from infections.
