Take my breath away.

There are many ways to change a person's breathing rate, and the easiest way to change your respiratory rate is to exercise and get physical. This process would drain your energy and cause your heart to beat faster, thus, having you to crave more air. Second way is by coughing or choking. This would also have you desperate for air. Lastly, people who have asthma may cause their breathing rate to change. Asthma is a chronic disease involving the respiratory system, which constricts the airways and makes it more difficult to breathe.

The confusion of cardiovascular system

Based on my own knowledge, the circulatory system is what helps fight off diseases and help maintain appropriate temperature. This part also distributes blood throughout the body. Although what confuses me is how can someone encounter a cardiovascular disease, and what should that person do when this happens. This surprises me because this helps the body by fighting unwanted diseases from the body.
