The three terms that refer to the passage of urine from the body or the emptying of the bladder are A. Micturition, urination, and voiding. These terms describe the process where the urinary bladder releases urine through the urethra to the outside of the body.
Step-by-step explanation:
Terms for the Passage of Urine
The correct answer to the question “What are three terms that all refer to the passage of urine from the body or the emptying of the bladder?” is A. Micturition, urination, voiding. These terms describe the process by which urine is expelled from the urinary bladder through the urethra to the outside of the body.
Micturition Reflex
Micturition is a term that specifically refers to the process whereby the bladder discharges urine, which involves a reflex arc and voluntary control over the internal and external urethral sphincters. As the bladder becomes filled, sensory nerves send signals to the brain indicating the need to urinate, and when appropriate, the brain signals the bladder to contract, allowing urine to be expelled.
Urinary Excretion Process
In the urinary system, urine formation follows several steps: glomerular filtration, tubular reabsorption, and tubular secretion. After urine is formed, it is then collected in the kidneys' collecting ducts. From there, it travels through the ureters to the bladder for storage until it is ready to be voided from the body during urination. Urination is a common term for this process used in everyday language.
The Act of Voiding
Voiding is another term that is equivalent to urination and refers to the act of emptying the bladder. It is an intentional release of urine out of the urethra to eliminate waste fluids from the body.
