The connection is: your heart is dependent on oxygen from your respiratory system, and it is delivered by the circulatory system.

The connection between the heart's dependency on oxygen from the respiratory system and its delivery is through the circulatory system. The circulatory system is responsible for transporting oxygen-rich blood from the lungs, where it is acquired through respiration, to the heart. From the heart, the circulatory system then distributes this oxygenated blood to all the body's tissues and organs, including the heart itself. Therefore, the correct answer is the circulatory system.

The correct answer is the circulatory system.

To understand why, let's break it down step by step:

1. The heart is a vital organ responsible for pumping blood throughout the body.

2. Oxygen is necessary for the proper functioning of the cells in the body, including the cells in the heart.

3. The respiratory system, specifically the lungs, play a crucial role in delivering oxygen to the body. When you inhale, oxygen is taken in through the air and transported to the lungs.

4. However, simply having oxygen in the lungs is not enough. It needs to be delivered to the cells in the body, including the heart.

5. This is where the circulatory system comes into play. The circulatory system, which consists of the heart, blood vessels, and blood, carries oxygen-rich blood from the lungs and distributes it to the different parts of the body.

6. The heart pumps oxygen-rich blood throughout the circulatory system, ensuring that all the cells, including the heart itself, receive oxygen.

So, in summary, while the respiratory system is responsible for taking in oxygen, it is the circulatory system that delivers this oxygen to the heart and other organs in the body.
