The circulatory system is one of the most important body systems. There are two main types of circulation in the body – systemic and pulmonary. The difference between these two types of circulation is how the blood is pumped throughout the body. In the systemic circulation, the heart pumps blood out to all parts of the body. In pulmonary circulation, the heart pumps blood to the lungs first, where it picks up oxygen. Then, the blood is pumped back out to all parts of the body. Let’s take a closer look at each type of circulation.”
What is Systemic Circulation?
Systemic circulation is the movement of blood through the body, away from the heart. The blood carries oxygen and nutrients to the tissues, and carbon dioxide and other waste products back to the heart. Systemic circulation is a key part of the circulatory system, which also includes the lungs (pulmonary circulation) and the heart (coronary circulation).
Systemic circulation is often divided into two parts: the arterial system and the venous system. The arterial system carries blood away from the heart, while the venous system returns blood to the heart. Systemic circulation is necessary for survival; without it, tissues would not receive the oxygen and nutrients they need to function.
What is Pulmonary Circulation?
Pulmonary circulation is the movement of blood from the heart, to the lungs, and back to the heart again. The Pulmonary veins return oxygenated blood from the lungs to the left atrium of the heart. Pulmonary arteries carry deoxygenated blood from the right ventricle of the heart to the lungs. In the lungs, pulmonary capillaries supply deoxygenated blood, which then picks up oxygen and carbon dioxide is removed.
This process is known as gas exchange. After gas exchange takes place in the alveoli of the lungs, oxygenated blood is carried back to the heart through pulmonary veins, and the cycle repeats. Pulmonary circulation is a vital part of keeping our bodies supplied with oxygenated blood. Without it, we would not be able to survive.
Difference between Systemic Circulation and Pulmonary Circulation
Systemic circulation is the circulation of blood from the left ventricle of the heart throughout the body and back to the right atrium of the heart. Systemic circulation carries oxygenated blood to all parts of the body except for the lungs.
- Pulmonary circulation is the circulation of blood from the right ventricle of the heart to the lungs and back to the left atrium of the heart. Pulmonary circulation carries deoxygenated blood to and from the lungs. Systemic circulation and pulmonary circulation are two types of circulatory systems in animals.
- Systemic circulation is responsible for delivering oxygenated blood to tissues, while pulmonary circulation is responsible for delivering deoxygenated blood to and from lungs. Both types of circulations are vital for life.
- Systemic circulation would not be possible without pulmonary circulation, and vice versa. Systemic and pulmonary circulations work together to ensure that oxygenated blood is delivered to tissues and that carbon dioxide is removed from tissues. Systemic and pulmonary circulations are two essential circulatory systems in animals.
The two circulations, systemic and pulmonary, have different purposes. The systemic circulation distributes blood throughout the entire body, while the pulmonary circulation only distributes blood to the lungs. Understanding these differences can help you better care for your patients.
