The Excretory System Test Quiz! Trivia

2.

Name 4 parts used in the excretory system.

Explanation
The excretory system is responsible for eliminating waste products from the body. The skin plays a role in excretion by releasing sweat, which contains waste products such as urea and salt. The bladder is a part of the urinary system and stores urine before it is eliminated from the body. The kidneys filter waste products from the blood and produce urine. The liver is involved in the excretory system by breaking down toxins and producing bile, which is then eliminated through the digestive system. These four parts work together to remove waste and maintain the body's homeostasis.

The second layer in the skin is called the

Explanation
The second layer in the skin is called the dermis. The dermis is located beneath the epidermis and is responsible for providing strength, elasticity, and structural support to the skin. It contains various structures such as blood vessels, hair follicles, sweat glands, and nerve endings. The dermis also plays a crucial role in regulating body temperature and protecting the body from external factors. Overall, the dermis is essential for maintaining the integrity and functionality of the skin.

4.

What does the bladder hold?

Explanation
The bladder holds unnecessary wastes for storage. This means that the bladder is responsible for storing waste materials, such as urine, until it is ready to be expelled from the body. The bladder acts as a reservoir, allowing the body to control the release of waste at appropriate times.

5.

What three parts make up a kidney?

Explanation
The kidney is made up of three main parts: the renal cortex, renal medulla, and renal pelvis. The renal cortex is the outer layer of the kidney and contains the glomeruli and renal tubules. The renal medulla is the inner region of the kidney and consists of renal pyramids and collecting ducts. The renal pelvis is the central collecting region of the kidney where urine is collected before it is passed to the bladder. These three parts work together to filter waste products from the blood and produce urine.

6.

The bladder filters out nitrogenous waste from the body.

True
False

Correct Answer

A. False

Explanation

The bladder does not filter out nitrogenous waste from the body. The bladder is responsible for storing urine that has already been filtered by the kidneys. The kidneys are the organs that filter waste products, including nitrogenous waste, from the bloodstream and produce urine. The urine then travels from the kidneys to the bladder for storage until it is eliminated from the body. Therefore, the statement that the bladder filters out nitrogenous waste is false.

7.

The liver is only part of the excretory system.

True
False

Correct Answer

A. False

Explanation

The liver is not part of the excretory system. While it does play a role in detoxification and metabolism, its primary function is to produce bile, which aids in digestion. The excretory system, on the other hand, is responsible for eliminating waste products from the body, primarily through the kidneys, urinary bladder, and urethra. Therefore, the statement that the liver is only part of the excretory system is false.

8.

The liver holds unnecessary wastes for storage.

True
False

Correct Answer

A. False

Explanation

The liver does not hold unnecessary wastes for storage. Instead, it plays a crucial role in detoxifying the blood, metabolizing drugs and toxins, and producing bile to aid in digestion. The liver also stores important substances such as vitamins, minerals, and glycogen. Therefore, the given statement is false.

9.

The skin's role in the excretory system is to produce sweat.

True
False

Correct Answer

A. True

Explanation

The skin plays a crucial role in the excretory system by producing sweat. Sweat contains waste products like urea, salts, and water, which are excreted through the skin's sweat glands. This process helps regulate body temperature and remove toxins from the body. Therefore, the statement "The skin's role in the excretory system is to produce sweat" is true.

What are the three layers of the skin in order?

Hypodermis,Dermis,and Epidermis
Dermis,Hypodermis,and Epidermis
Epidermis,Dermis,and Hypodermis
Epidermis,Hypodermis,and Dermis

Correct Answer

A. Epidermis,Dermis,and Hypodermis

Explanation

The correct order of the three layers of the skin is epidermis, dermis, and hypodermis. The epidermis is the outermost layer of the skin, providing protection and serving as a barrier against external factors. The dermis is the middle layer, containing blood vessels, nerves, hair follicles, and sweat glands. It provides structural support and elasticity to the skin. The hypodermis is the innermost layer, consisting of fat and connective tissue. It acts as insulation and cushioning for the body.
