Question

which two systems work together to deliver oxygen to the body’s cells and remove carbon dioxide?
a. nervous and muscular systems
b. circulatory and respiratory systems
c. digestive and skeletal systems
d. endocrine and immune systems

question 2
match each pair of systems with their interaction:

• digestive and circulatory systems
• integumentary and immune systems
• integumentary and lymphatic systems
• skeletal and muscular systems

Explanation:

1. For the first question: The respiratory system takes in oxygen and removes carbon dioxide, while the circulatory system transports these gases to and from body cells, working together to fulfill this gas exchange function.
2. For the matching question (Question 2):

• The digestive system breaks down food into nutrients, and the circulatory system carries these nutrients to body cells.
• The nervous system sends signals to control muscle contractions, and the muscular system carries out the movement/response.
• The immune system uses lymphatic vessels to transport immune cells and fluid, and the lymphatic system supports immune function by filtering pathogens.
• The skeletal system provides a framework for muscles to attach to, and the muscular system moves the skeleton.

Answer:

First question:
C. Circulatory and Respiratory Systems

Question 2 (matches):

• Digestive and Circulatory Systems: Transport nutrients to cells
• Nervous and Muscular Systems: Control muscle movement
• Immune and Lymphatic Systems: Support immune response/fluid transport
• Skeletal and Muscular Systems: Enable body movement
