The main job of systemic circulation in our bodies is to carry oxygen-rich blood from the heart to all our organs and tissues. It also brings deoxygenated blood back to the heart.
Oxygen Delivery: When we breathe in, our lungs grab oxygen. This oxygen travels through the left side of the heart and is then pumped into a big artery called the aorta. The oxygen-filled blood goes all over the body to keep us alive.
Nutrient Distribution: Besides oxygen, systemic circulation also carries important nutrients from our food. These nutrients are sent to our cells to help them use energy and heal when needed.
Waste Removal: As blood flows through our body, it picks up waste products like carbon dioxide and urea. This waste is then sent to the kidneys and lungs so our body can get rid of it.
Direction of Blood Flow: Systemic circulation sends blood away from the heart to the rest of the body. On the other hand, pulmonary circulation takes blood from the heart to the lungs to get more oxygen.
Oxygen Content: Blood in systemic circulation is usually bright red since it has a lot of oxygen. Blood in pulmonary circulation is dark red because it doesn’t have much oxygen.
Pressure Levels: Systemic circulation works under higher pressure than pulmonary circulation. This is because blood has to travel further and face more resistance in the body.
In short, systemic circulation is really important for keeping our bodies stable and making sure that every cell gets the oxygen and nutrients it needs to work well. It’s amazing to think about how our heart and blood vessels team up to help us stay healthy!
