where is the diagram .
Pulmonary circulation and Systematic circulation are the two functions represented here.
1) Pulmonary artery
3) Pulmonary vein
6) Systemic vein.
b) Pulmonary artery carrier deoxygenated blood from right ventricle to lungs.
Pulmonary vein carrier oxygenated blood from lungs to left auricle.

Given image is the diagrammatic representation of double circulation.

(ii) Functions shown in the figure -Pulmonary circulation - movement of deoxygenated blood from the heart to the lungs and return of oxygenated blood to the heart again. Systemic circulation - movement of oxygenated blood from the heart to the body tissues and return of deoxygenated blood to the heart again.
it is heart
makes blood pure
removes carbon dioxide from our body
makes it possible for other cell to live .
Vertebrates, and a few invertebrates, have a closed circulatory system, shown in Figure 2. Closed circulatory systems (evolved in echinoderms and vertebrates) have the blood closed at all times within vessels of different size and wall thickness. In this type of system, blood is pumped by a heart through vessels, and does not normally fill body cavities. Blood flow is not sluggish. Hemoglobin causes vertebrate blood to turn red in the presence of oxygen; but more importantly hemoglobin molecules in blood cells transport oxygen. The human closed circulatory system is sometimes called the cardiovascular system. A secondary circulatory system, the lymphatic circulation, collects fluid and cells and returns them to the cardiovascular system.Living things must be capable of transporting nutrients, wastes and gases to and from cells. Single-celled organisms use their cell surface as a point of exchange with the outside environment. Multicellular organisms have developed transport and circulatory systems to deliver oxygen and food to cells and remove carbon dioxide and metabolic wastes. Sponges are the simplest animals, yet even they have a transport system. Seawater is the medium of transport and is propelled in and out of the sponge by ciliary action. Simple animals, such as the hydra and planaria (shown in Figure 1), lack specialized organs such as hearts and blood vessels, instead using their skin as an exchange point for materials. This, however, limits the size an animal can attain. To become larger, they need specialized organs and organ systems.Multicellular animals do not have most of their cells in contact with the external environment and so have developed circulatory systems to transport nutrients, oxygen, carbon dioxide and metabolic wastes. Components of the circulatory system include
blood: a connective tissue of liquid plasma and cells
heart: a muscular pump to move the blood
blood vessels: arteries, capillaries and veins that deliver blood to all tissues
There are several types of circulatory systems. The open circulatory system, examples of which are diagrammed in Figure 2, is common to molluscs and arthropods. Open circulatory systems (evolved in insects, mollusks and other invertebrates) pump blood into a hemocoel with the blood diffusing back to the circulatory system between cells. Blood is pumped by a heart into the body cavities, where tissues are surrounded by the blood. The resulting blood flow is sluggish.
1. Pulmonary artery to lungs
2. Lung capillaries
3. Pulmonary vein from lungs
4. Aorta to body
5. Capillaries in body organs
6. Vena cava from body
(b) The two functions represented are:-
1. Transport of Oxygen and Carbon dioxide.
2. Exchange of Oxygen and Carbon dioxide.
It is depicting the proper functioning of these organs which is known as the pulmonary circulation.
Blood circles through the heart, which pumps it to the lungs where it picks up oxygen - this is the pulmonary
Pulmonary circulation is when blood circles through the heart that pumps it to lungs where it acquires fresh oxygen. The ventricle has two chambers and there is a four-chambered heart.
The circuit begins when right ventricle pumps de-oxygenated blood through the pulmonary artery. This artery gets divided into the left and right lungs. Here they get subdivided into small branches till they reach capillaries in the alveoli.
Here, the blood takes up fresh oxygen from the air sacs and releases carbon dioxide. It then needs to flow back into large vessels reaching the pulmonary veins. These vein open into the left atrium of heart. The heart then pumps the oxygen-rich blood to the rest of the body - this is which is known as the systemic circulation.
