What does L&H mean in PHYSIOLOGY

The lungs bring oxygen into our body via inhalation and remove carbon dioxide from our body via exhalation. This process is known as respiration.

Oxygen is a critical component of human life because it helps to provide energy to cells in the body, which are necessary for proper functioning. Without oxygen, cells cannot produce energy and many bodily functions become impaired or stop altogether.

The heart pumps blood throughout the body, including to vital organs like the brain, lungs, kidneys, liver, etc., delivering oxygen as well as nutrients that support life functions. When not operating efficiently, these vital processes can be compromised leading to organ damage or failure.

Poor lifestyle choices such as smoking cigarettes or eating an unhealthy diet high in saturated fats can lead to higher risk of cardiovascular disease affecting both your lung and heart health over time. Additionally, certain illnesses such as respiratory diseases or diabetes can exacerbate existing conditions such as high blood pressure or coronary artery disease leading to reduced lung or heart capacity respectively.

There are several steps people can take to reduce their risk of developing chronic cardiopulmonary diseases. Eating a balanced diet low in fat with plenty of fruits and vegetables; exercising regularly; avoiding tobacco use; keeping stress levels under control; getting regular screenings for early detection of potential problems; managing chronic conditions like hypertension or diabetes; quitting smoking if you currently smoke - all these steps help keep your lungs and heart working optimally for longer.
