Difference Between Systemic Circulation and Pulmonary Circulation

Systemic Circulation vs. Pulmonary Circulation

The function of the circulatory system in the human body is to supply nutrients and oxygen to the tissues, but also carry away waste products to the lungs and the kidneys for excretion. This system is known to cooperatively circulate all over the body. The blood flows in a succession of blood vessels filled with blood cells and plasma. The components of plasma and blood cells will depend on the direction they are flowing. The blood coming from the heart carries oxygenated blood throughout the body, and the blood that comes back to the heart is deoxygenated.

The circulation of these systems is composed of veins and arteries. In both pulmonary and systemic circulation, the artery that branches from the heart carries blood to other parts of the body. Veins are the blood vessels that carry back blood to the heart. The purpose of the whole system relies on the pulmonary circulation. Any disturbance in its comparatively short course can create disruptions in the systemic circulation, a sequela condition. The pulmonary blood vessels transport blood between the lungs and the heart. The lungs are the only structure that gas exchanges can come about. Without this mechanism, the systemic circulation cannot function properly.

These two systems are blocked arrangements in which the flow of blood from the heart comes back to the heart. The communication between veins and arteries in these two systems are the capillaries. These are thin-walled blood vessels with a width of a single RBC or red blood cell. The composition of capillaries allows the passageway of blood cells and a trouble-free exchange of oxygen and nutrients. Inside the lungs, the capillary beds are adjoined to the thin-walled air sacs called alveoli which allow a competent gas exchange.

There were identified major disparities between the pulmonary and systemic circulations. The systemic circulation comprises different forms of blood vessels, such as muscular tissues, that branch into much smaller sizes throughout the body. The pulmonary circulation comprises two main vessels which branch to the lungs. The systemic circulation composes arteries transporting oxygenated blood to other tissues commencing in the heart’s left ventricle. The pulmonary circulation has the pulmonary artery as its main structure. This artery transports deoxygenated blood towards the lungs through the right ventricle.

Systemic circulation has veins that transport deoxygenated blood towards the heart. The blood then empties into the heart’s right atrium. Pulmonary circulation has the pulmonary vein that transports oxygenated blood towards the heart infilling the heart’s left atrium. The systemic structures bring oxygen and transport away carbon dioxide. Inside the lungs, there would be an exchange of oxygen and carbon dioxide within the blood.

These two systems of the circulatory component of the body work together in harmony or symbiotically to attain the most fundamental level of equilibrium or homeostasis (a stable organism that results in good mental and physical health). The circulatory system in general transmits oxygenated blood to other parts of the body. This system as well collects waste substances, such as carbon dioxide, from every tissue and cell and brings back the blood to the lungs where they are barred. This system is an incessant circuit and is essential for life.

Summary:

1.The circulation of these systems composes veins and arteries. In both pulmonary and systemic circulation, the artery that branches from the heart carries blood to other parts of the body. Veins are the blood vessels that carry back blood to the heart.

2.The purpose of the whole system relies on the pulmonary circulation. Any disturbance in its comparatively short course can create disruptions in the systemic circulation, a sequela condition.

3.The pulmonary blood vessels transport blood between the lungs and the heart. The lungs are the only structure that gas exchanges can come about. Without this mechanism, the systemic circulation cannot function properly.
4.Systemic circulation has veins that transports deoxygenated blood towards the heart. The blood then empties into the heart’s right atrium. Pulmonary circulation has the pulmonary vein that transports oxygenated blood towards the heart infilling the heart’s left atrium.
