Question

Which of the following structures stores waste before it is released from the body?

a. kidney
b. urethra
c. ureters
d. urinary bladder

Answer 1

The correct option is :

d. Urinary bladder

Step-by-step explanation:

The urinary bladder, represented by option d, functions as the organ responsible for storing waste before its elimination from the body. Once the kidneys filter waste and excess fluids from the blood, this waste, in the form of urine, travels through the ureters and accumulates in the urinary bladder. The bladder serves as a reservoir, storing urine until the body signals the need for elimination.

The bladder's capacity varies among individuals but typically holds around 400-600 milliliters of urine. As the bladder fills, nerve signals indicate the need to urinate, initiating the sensation of urgency. When the bladder reaches its capacity or an appropriate time for elimination arises, the muscular walls contract, allowing urine to pass through the urethra and exit the body.

Understanding the role of the urinary bladder in storing waste underscores its importance in the urinary system's function. Its ability to temporarily retain urine allows for controlled and timely elimination, contributing to the body's waste removal process while maintaining continence and control over urination. Dysfunction or issues with the bladder can lead to various urinary problems, emphasizing the significance of this organ in maintaining overall health and homeostasis.

Answer 2

The urinary bladder is the structure that stores waste before it is released from the body.The correct option is d. urinary bladder

Explanation:

The urinary system is responsible for filtering waste products from the blood and eliminating them from the body. The kidneys, ureters, bladder, and urethra are the four main structures that make up this system. While the kidneys filter waste and excess water, the ureters transport urine to the bladder, and the urethra carries urine out of the body.

The urinary bladder is a muscular sac located in the pelvis that stores urine until it is eliminated. When the bladder is empty, it is flaccid and holds only a small amount of urine. As more urine is produced by the kidneys, it fills the bladder, causing it to expand and contract as needed. The bladder has a capacity of about 500 milliliters (ml) in adults, although this can vary depending on factors such as age and gender.

When it is time to eliminate urine, signals are sent to the brain, which triggers a reflex that causes the bladder to contract and push urine out through the urethra. This process is known as micturition or urination. The ability to control this reflex is learned during childhood and allows individuals to delay urination until an appropriate time and place.

In summary, the urinary bladder is a muscular sac that stores urine until it is eliminated from the body through micturition. Its ability to expand and contract allows it to hold large volumes of urine without causing discomfort or overflow incontinence. Understanding how this structure functions is important for maintaining overall health and preventing urinary tract disorders such as overactive bladder or urinary retention.

Therefore, The correct option is d. urinary bladder
