Factors That Affect Respiration Rate

The brain is the primary controller of respiratory rate. It receives input from sensors that detect oxygen and carbon dioxide levels in the blood. Blood pH -- a reflection of its relative acidity or alkalinity -- also influences respiratory rate.

Factors of Body Equilibrium & Balance

Factors that affect equilibrium and balance in the body include breathing, vision, vestibular function, musculoskeletal alignment and proprioception. The eyes, vestibular system and proprioceptors of the neck read and adjust head placement in relation to the environment.

How Does the Cardiovascular System Work With the Respiratory System?

An understanding of how the respiratory and cardiovascular systems interact requires knowledge of how each of the systems function independently. The cardiovascular system in the human body is made up of the heart and blood vessels, which are divided into arteries, veins and capillaries.

Ingredients in an Asthma Inhaler

Asthma is a chronic lung disease characterized by increased mucus production and airway narrowing due to swelling and tightening of the airway muscles. Inhalers are frequently used to manage asthma and treat attacks. They deliver medication directly into the lungs rather than traveling through the bloodstream.
