Answer 1

Here are the answers to your questions:

1. Which component of blood allows oxygen from the air to move from the lungs to cells of the body?

   • Red blood cells – they contain hemoglobin, which binds to oxygen and transports it to cells.

2. Ventricles pump blood out of the heart. Which types of vessels will be the first to contact the blood from the ventricles?

   • Arteries – they carry blood away from the heart.

3. Which best describes carbon dioxide’s path out of the body?

   • Alveoli → bronchus → trachea → larynx → pharynx → nose – this is the correct path for CO2 to exit.

4. Which structure is also called the windpipe?

   • The trachea – it is commonly referred to as the windpipe.

5. Which is located inside the lung?

   • The alveoli – these are small air sacs where gas exchange occurs.

6. Which is the next structure to contact air after it passes from the nose to the nasal cavity?

   • The pharynx – it is the next part of the pathway for air.

7. The picture represents the respiratory system. The respiratory system. X points to the windpipe. Which structure is represented by the X?

   • The trachea – as noted earlier, the windpipe is the trachea.

8. Which statement explains blood pressure?

   • Blood pressure is highest in the arteries near the heart. – this is true as blood is pumped forcefully by the heart into the arteries.

9. At the site of gas exchange in the lungs, where does the oxygen move?

   • O2 moves from the alveoli to the red blood cells. – oxygen diffuses into the blood in the alveoli.

10. Which gases are carried by red blood cells? Select two options.

• Oxygen and carbon dioxide – red blood cells transport both of these gases in the bloodstream.

Answer 2

9. O2 moves from the alveoli to the red blood cells.

Answer 3

Yes, that's correct!

At the site of gas exchange in the lungs, oxygen (O2) moves from the alveoli (the tiny air sacs in the lungs where gas exchange occurs) into the red blood cells. This process allows the oxygen to be transported throughout the body to the cells where it is needed.

Answer 4

Which statement correctly describes organs?

An organ is a group of cells that work together to perform a common function.
An organ is a group of systems that work together to perform a common function.
An organ is a group of tissues that work together to perform a common function.

Answer 5

The correct statement is:

An organ is a group of tissues that work together to perform a common function.

Organs are made up of different types of tissues working in coordination to carry out specific functions within an organism. For example, the heart is an organ composed of muscle tissue, connective tissue, and epithelial tissue, all working together to pump blood.
