Biology Quiz: Homeostasis and the Human Urinary System

What does homeostasis mean?

• Maintenance of cell structure

• Regulation of internal environment

• Control of external factors

• Breakdown of external environment

How are body temperature, blood sugar level, the partial pressure of carbon dioxide, and blood pressure regulated?

• Integumentary system, nervous system, and muscle system

• Circulatory system, nervous system, and muscle system

• Endocrine system, circulatory system, and digestive system

• Respiratory system, circulatory system, and nervous system

What is the structure and function of the kidney?

• Excretion of nitrogenous wastes

• Regulation of blood sugar

• Excretion of oxygen

• Regulation of body temperature

How is urine formed?

• Filtration, digestion, and absorption

• Secretion, assimilation, and excretion

• Digestion, absorption, and assimilation

• Ultrafiltration, reabsorption, and secretion

How does the negative feedback mechanism in homeostasis happen?

• By increasing the deviation from normal range

• By maintaining the deviation from normal range

• By ignoring the deviation from normal range

• By returning the factor's value to the normal range

What are the health issues related to the urinary system?

• Urinary tract infections

• Cardiovascular diseases

• Musculoskeletal disorders

• Respiratory disorders

Explain the meaning of homeostasis.

• Control of external factors

• Regulation of internal environment

• Breakdown of external environment

• Maintenance of cell structure

Justify the necessity to maintain physical and chemical factors in the internal environment.

• To disrupt cell function

• To optimize cell metabolism

• To increase external changes

• To decrease cell activity

Describe the involvement of various organ systems in maintaining an optimal internal environment.

• Endocrine system only

• Multiple organ systems

• Circulatory system only

• Nervous system only

Apply the knowledge of homeostasis concept in regulation of body temperature.

• Endocrine system

• Integumentary system

• Respiratory system

• Muscle system
