explain circulatory system
Answers
Answer:
Hi there !
see,
the circulatory system consists of heart, veins, arteries, capillaries.
heart is pumping organ
veins carries deoxygenated blood (except pulmonary vein.)
arteries carries oxygenated blood (except pulmonary artery)
capillaries are the link between veins and arteries. They are the thinnest among all because they have to transport blood into each and every cell of the body.
Explanation:
all the deoxygenated blood from the body is carried by Vena Cava to right auricular heart.
this is transferred to the right ventrical.
this deoxygenated blood is carried to the lungs for oxygenation by pulmonary artery.
the blood gets oxygenated in lungs and comes back to left aurical of heart by pulmonary vein.
the blood is transferred to left ventrical then.
and at last the blood is carried to all the parts of the body by aorta.
In humans double circulation takes place as the blood comes two times to the heart at a time.
That was the complete circular system
Hope it helps :)

Explanation:
The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis.
Circulatory system
Circulatory System
The human circulatory system (simplified). Red indicates oxygenated blood carried in arteries. Blue indicates deoxygenated blood carried in veins. Capillaries, which join the arteries and veins, and the lymphatic vessels
The circulatory system includes the lymphatic system, which circulates lymph.The passage of lymph takes much longer than that of blood.Blood is a fluid consisting of plasma, red blood cells, white blood cells, and platelets that is circulated by the heart through the vertebrate vascular system, carrying oxygen and nutrients to and waste materials away from all body tissues. Lymph is essentially recycled excess blood plasma after it has been filtered from the interstitial fluid (between cells) and returned to the lymphatic system. The cardiovascular (from Latin words meaning "heart" and "vessel") system comprises the blood, heart, and blood vessels. The lymph, lymph nodes, and lymph vessels form the lymphatic system, which returns filtered blood plasma from the interstitial fluid (between cells) as lymph.
The circulatory system of the blood is seen as having two components, a systemic circulation and a pulmonary circulation.
While humans, as well as other vertebrates, have a closed cardiovascular system (meaning that the blood never leaves the network of arteries, veins and capillaries), some invertebrate groups have an open cardiovascular system. The lymphatic system, on the other hand, is an open system providing an accessory route for excess interstitial fluid to be returned to the blood.The more primitive, diploblastic animal phyla lack circulatory systems.
