Human Body Systems Challenge

What is the primary function of the muscular system?

• Storing nutrients and energy.

• Facilitating movement of the body.

• Regulating body temperature.

• Producing hormones for growth.

Name the three types of muscles found in the human body.

• Epithelial muscle, connective muscle, neural muscle

• Tendons, ligaments, cartilage

• Skeletal muscle, smooth muscle, cardiac muscle

• Voluntary muscle, involuntary muscle, reflex muscle

What is the role of red blood cells in the circulatory system?

• Red blood cells help in digestion and nutrient absorption.

• Red blood cells are responsible for blood clotting.

• Red blood cells produce hormones in the circulatory system.

• Red blood cells transport oxygen and carbon dioxide in the circulatory system.

How does the heart contribute to the circulatory system?

• The heart filters toxins from the blood.

• The heart stores excess nutrients for later use.

• The heart acts as a pump to circulate blood throughout the body, facilitating the transport of oxygen, nutrients, and waste removal.

• The heart produces hormones that regulate blood pressure.

What are the main organs involved in the respiratory system?

• Eyes, ears, mouth, teeth

• Skin, muscles, bones, brain

• Nose, pharynx, larynx, trachea, bronchi, lungs

• Heart, liver, kidneys, stomach

Explain the process of gas exchange in the lungs.

• Gas exchange in the lungs occurs in the alveoli, where oxygen is absorbed into the blood and carbon dioxide is released.

• Gas exchange happens in the diaphragm, which regulates breathing and oxygen intake.

• Gas exchange occurs in the trachea, where oxygen is filtered from the air.

• Carbon dioxide is absorbed into the blood while oxygen is released in the bronchi.

What is the significance of the diaphragm in respiration?

• The diaphragm only helps with swallowing food.

• The diaphragm is responsible for blood circulation.

• The diaphragm has no role in the respiratory process.

• The diaphragm is crucial for inhalation and exhalation, facilitating airflow in and out of the lungs.

How do the circulatory and respiratory systems work together?

• The circulatory and respiratory systems work together to exchange oxygen and carbon dioxide, facilitating respiration and cellular metabolism.

• The circulatory system transports nutrients to the lungs.

• The respiratory system pumps blood throughout the body.

• The circulatory system filters toxins from the air.
