are lungs a part of the circulatory system?

The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic). The system is responsible for the flow of blood, nutrients, oxygen and other gases, and as well as hormones to and from cells.

The blood vessels are the components of the circulatory system that transport blood throughout the human body. These vessels transport blood cells, nutrients, and oxygen to the tissues of the body. They also take waste and carbon dioxide away from the tissues.

Lungs are sacks of tissue located just below the rib cage and above the diaphragm. They are an important part of the respiratory system and waste management for the body.

The lungs are housed in the chest cavity, a space that also includes the mediastinum. (See also Overview of the Respiratory System.) The mediastinum is in the center of the chest and contains the heart, thymus, and lymph nodes, along with portions of the aorta, vena cava, trachea, esophagus, and various nerves.

The essential components of the human cardiovascular system are the heart, blood and blood vessels. It includes the pulmonary circulation, a "loop" through the lungs where blood is oxygenated; and the systemic circulation, a "loop" through the rest of the body to provide oxygenated blood.

Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart. Systemic circulation moves blood between the heart and the rest of the body.

The liver is involved in the digestion system while lungs are involved in the respiration system. There is one liver in our body. On the other hand, there are two lungs, the right, and the left lung in every human body. Liver stores glucose and fat while lungs do not perform any storage function as such.

The four main parts of the circulatory system are the heart, arteries, veins and blood. Let's have a closer look at how they operate in the body.

Lung tissue consists mainly of alveoli (Figure 16.2.6). These tiny air sacs are the functional units of the lungs where gas exchange takes place. The two lungs may contain as many as 700 million alveoli, providing a huge total surface area for gas exchange to take place.

Lungs are a pair of highly elastic and spongy organs in the chest. They are the main organs involved in breathing. They take in air from the atmosphere and provide a place for oxygen to enter the blood and for carbon dioxide to leave the blood.

The secret role of the lungs – a healthy immune system. The lungs are not only essential oxygenating the body, but they also play a role in immune health. Naturopath Jodi Van Dyk explains. The lungs are a very important organ, as they enable us to breathe and obtain oxygen to fuel our bodies.

The lungs are located on either side of the breastbone in the chest cavity and are divided into five main sections (lobes). The lungs are responsible for removing carbon dioxide from the blood and adding oxygen to it. The heart and lungs work together to do this.

The circulatory system of the blood is seen as having two components, a systemic circulation and a pulmonary circulation.

The vascular system, also called the circulatory system, is made up of the vessels that carry blood and lymph through the body. The arteries and veins carry blood throughout the body, delivering oxygen and nutrients to the body tissues and taking away tissue waste matter.

The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs. The blood here passes through capillaries adjacent to alveoli and becomes oxygenated as part of the process of respiration. In contrast to the pulmonary arteries, the bronchial arteries supply nutrition to the lungs themselves.

Blood reaches from the pulmonary circulation into the lungs for gas exchange to oxygenate the rest of the body tissues. But bronchial circulation supplies fully oxygenated arterial blood to the lung tissues themselves.
