What is the difference between pulmonary circulation and systemic circulation

Pulmonary Circulation: Pulmonary circulation carries oxygenated blood from the lungs to the left atrium of the heart by the pulmonary vein. Systemic Circulation: Systemic circulation carries deoxygenated blood from the body to the right atrium of the heart by the superior and inferior vena cava. Pulmonary Circulation: Pulmonary circulation is composed of pulmonary artery and pulmonary vein.

Systemic Circulation: Systemic circulation is composed of inferior and superior vena cava, aorta, and other small blood vessels.

Pulmonary Circulation: Pulmonary circulation carries blood to the lungs. Systemic Circulation: Systemic circulation carries blood throughout the body. Pulmonary Circulation: Pulmonary circulation helps to release carbon dioxide from the blood while dissolving oxygen in the blood.

Systemic Circulation: Systemic circulation helps to provide nutrients and oxygen to the metabolizing cells in the body. Pulmonary and systemic circulation are two types of circulations that maintain the homeostasis in the body of many mammals. The pulmonary circulation carries deoxygenated blood from the heart to the lungs and returns to the heart.

The systemic circulation carries that oxygenated blood from the heart to the rest of the body and returns the deoxygenated blood back to the heart. The main function of the pulmonary circulation is to oxygenate the blood while the main function of the systemic circulation is to distribute oxygen and nutrients throughout the body while removing the metabolic wastes.

On the basis of this, the following summary table was constructed. It incorporates elements from the chapters on pulmonary vascular anatomy and physiology as well as corresponding chapters regarding the systemic circulation. Vessels are dependent on alveolar pressure surrounted by intrathoracic air , and expand by radial traction as the lung expands.

Filtration of arterial blood in the renal and heptic vascular beds results in the clearance of metabolic wastes and particles. Where would you find a reliable peer-reviewed resource for something like this? Nowhere, that's where. In the pulmonary circulation, the blood is circulated between the heart and the lungs, and further, transportation of deoxygenated blood to the lungs for absorption of oxygen and release of carbon dioxide is also done.

On the other hand, in systemic circulation, the blood is circulated between the heart and the rest of the body. The process of blood circulation from the heart to the lungs in order to absorb oxygen and release carbon dioxide by transporting deoxygenated blood to the lungs is known as pulmonary circulation.

In this process of blood circulation, a closed circuit is formed between the heart and the lungs because of the formation of the system of the blood vessels. The process of blood circulation from the heart to all the parts of the body is known as systemic circulation. Blood is supplied to all the tissues of the body during this circulation. It also supplies oxygen and other necessary nutrients to the body cells and drains out the carbon dioxide along with other waste products. It is found on the evolutionary cycle that pulmonary circulation first occurred in lungfishes.

The lungfishes were also the first animals to acquire a heart that had three chambers. However, the pulmonary circulation is different in mammals, crocodiles, and birds.
