Exploring Human Body Systems

What is the primary function of the circulatory system?

• To transport blood and nutrients throughout the body.

• To produce hormones for growth.

• To filter waste from the blood.

• To regulate body temperature.

Which organ is responsible for filtering blood in the human body?

• Kidneys

• Spleen

• Liver

• Pancreas

What system is responsible for transporting oxygen and carbon dioxide?

• The respiratory system

• The nervous system

• The circulatory system

• The digestive system

Name the largest organ in the human body.

• Skin

• Liver

• Lungs

• Heart

What is the role of the respiratory system?

• The role of the respiratory system is to facilitate gas exchange, providing oxygen to the body and removing carbon dioxide.

• To regulate body temperature

• To digest food and absorb nutrients

• To circulate blood throughout the body

Which system controls body movements and responses?

• Endocrine system

• Muscular system

• Nervous system

• Skeletal system

What is the function of the digestive system?

• The function of the digestive system is to process food for nutrient absorption and waste elimination.

• To circulate blood throughout the body.

• To regulate body temperature.

• To provide structural support to the body.

How do the nervous and endocrine systems work together?

• The nervous system only functions during sleep, while the endocrine system is active during the day.

• Both systems operate independently without any interaction.

• The nervous system provides quick responses, while the endocrine system offers longer-lasting hormonal regulation.

• The endocrine system controls muscle movements, while the nervous system regulates metabolism.

What are the main components of the immune system?

• Platelets

• Hormones

• Red blood cells

• White blood cells, antibodies, complement system, lymphatic system, spleen, thymus.

What is homeostasis and why is it important for the human body?

• Homeostasis is the process of breathing and is essential for oxygen intake.

• Homeostasis refers to the body's ability to grow and develop over time.

• Homeostasis is the regulation of body temperature only during exercise.

• Homeostasis is the maintenance of a stable internal environment in the body, and it is important for survival and proper functioning of biological systems.
