The Human Circulatory System

The Heart

The heart is an organ about the size of your fist that pumps blood through your body. It is made up of multiple layers of tissue. Your heart is in the center of your chest, near your lungs. It has four hollow chambers surrounded by muscle and other heart tissue. The chambers are separated by heart valves, which make sure that the blood keeps flowing in the right direction. 


What Is Angina?

Pain and discomfort are the main symptoms of angina. Angina is often described as pressure, squeezing, burning, indigestion, or tightness in the chest. The pain or discomfort usually starts behind the breastbone. Some people say that angina pain is hard to describe or that they cannot tell exactly where the pain is coming from.

Alpha-1 antitrypsin (AAT) deficiency

What is alpha-1 antitrypsin deficiency?

AAT is a protein made in your liver to help protect the lungs. If your body does not make enough AAT, your lungs are more easily damaged from smoking, pollution, or dust from the environment. This can lead to COPD. AAT deficiency may also cause a liver disease called cirrhosis. This is more common in children who have AAT deficiency.

Acute Respiratory Distress Syndrome

What Is Acute Respiratory Distress Syndrome?

Acute respiratory distress syndrome (ARDS) is a serious lung condition that causes low blood oxygen. In ARDS, fluid builds up inside the tiny air sacs of the lungs, and surfactant breaks down. Surfactant is a foamy substance made by your body that keeps your lungs fully expanded so you can breathe. The fluid buildup and lack of surfactant that happen because of ARDS prevent the lungs from properly filling with air and moving enough oxygen into the bloodstream and throughout the body.
