Biology TEKS 10A - Animal System Interactions

How do the circulatory system and immune system work together to respond to an injury?

• Increased blood flow kills healthy cells which prevents infection at the site of the injury.

• Increased blood flow removes infected cells from the body at the site of the injury.

• Increased blood flow carries white blood cells to the site of the injury.

• Increased blood flow allows for an increase in the exchange of O₂ and CO₂ at the site of the injury.

Which two body systems must directly interact for vertebrate organisms to exchange gases?

• Skeletal system and muscular system

• Excretory system and reproductive system

• Circulatory system and respiratory system

• Digestive system and immune system

Kidneys are part of the excretory system in a human body. They purify the impure blood and send it back to the rest of the body. Which system is mainly responsible for the transport of plasma to the kidneys?

• Respiratory system

• Circulatory system

• Muscular system

• Nervous system

During the process of nutrient absorption in animals, which two body systems are most responsible for breaking down food into smaller pieces and distributing the nutrients to body cells?

• Endocrine system and immune system
• Digestive system and circulatory system
• Nervous system and digestive system
• Muscular system and digestive system

As a runner begins to run a race, his or her respiration rate will increase. The runner begins to breathe deeper and at a rapid rate. In addition, the heart beats more quickly. This will result in more oxygen delivered to the muscle cells. Which two body systems are working together to help out the muscle cells?

• Immune system and lymphatic system
• Respiratory system and circulatory system
• Digestive system and integumentary system
• Lymphatic system and immune system

Dialysis is a medical treatment used when a person’s kidneys are no longer able to function. During this process, a machine uses an artificial membrane to remove waste products from the blood. Which body system below is not functioning properly in a person who requires dialysis?

• Endocrine system
• Integumentary system
• Excretory system
• Circulatory system

The two body systems that work together to protect you from foreign pathogens are...

• Integumentary and immune
• Reproductive and muscular
• Endocrine and digestive
• Respiratory and circulatory

In humans, the gases oxygen and carbon dioxide must be exchanged between the environment and cells. During this exchange, oxygen is delivered to the red blood cells so that they can function properly in the blood stream. Which two body systems are working together to achieve this goal?

• Endocrine and Reproductive

• Skeletal and Muscular

• Respiratory and Circulatory

• Digestive and Excretory

David has diabetes. His sugar level is often rising and lowering. Which body system is in charge of regulating his sugar levels?

• Excretory
• Endocrine
• Circulatory
• Nervous
