- The circulatory system comprises of the heart, the lungs and the  blood vessels. The main objective of the circulatory system is  transporting oxygenated (rich saturation of oxygen) blood around  the body. The de-oxygenated blood enters through the vena cava and  into the right atrium of the heart.

THE CIRCULATORY SYSTEM Closed circulatory system Vertebrates, and a few invertebrates, have a closed circulatory system. Closed circulatory systems 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. Open circulatory system The open circulatory system is common to molluscs and arthropods.Open circulatory systems (evolved in crustaceans, insects, mollusks and other invertebrates) pump blood into a hemocoel with the blood diffusing back to the circulatory system between cells.n this type of system, blood is pumped by a heart through vessels, and does not normally fill body cavities. Open circulatory system The open circulatory system is common to molluscs and arthropods.

Diagram of the Human Circulatory System (Infographic) 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.he systemic circulation is a major portion of the circulatory system. The network of veins, arteries and blood vessels transports oxygenated blood from the heart, delivers oxygen and nutrients to the body's cells and then returns deoxygenated blood back to the heart.

Circulatory system All cells in the body need to have oxygen and nutrients, and they need their wastes removed. These are the main roles of the circulatory system. The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.

What is the role of the circulatory system? The role of the circulatory system is to transport oxygen and other necessary nutrients all throughout the body. The main part of the circulatory system is the heart. The heart is the organ responsible for pumping blood throughout the body. This system has three types of blood vessels: The largest are arteries which go away from the heart. Next are veins which lead to the heart and are the second largest vessel.

The Human Body The Circulatory System by David. The Circulatory system pumps nutrients and other essential materials to the cells,and removes waste products from the cells through a system of vessels. It includes the blood, heart, and blood vessels of the body. For the circulatory system to function properly, movement has to take place between cells.

Circulatory System: Facts, Function & Diseases The systemic circulation is the portion of the circulatory system is the network of veins, arteries and blood vessels that transports blood from heart, services the body's cells and then re-enters the heart, the Mayo Clinic noted.n average adult has 5 to 6 quarts (4.7 to 5.6 liters) of blood, which is made up of plasma, red blood cells, white blood cells and platelets. In addition to blood, the circulatory system moves lymph, which is a clear fluid that helps rid the body of unwanted material.

Circulatory system The circulatory system of the lungs is the portion of the cardiovascular system in which oxygen-depleted blood is pumped away from the heart, via the pulmonary artery, to the lungs and returned, oxygenated, to the heart via the pulmonary vein.he circulatory system is often seen to comprise both the cardiovascular system, which distributes blood, and the lymphatic system, which circulates lymph. These are two separate systems. The passage of lymph for example takes a lot longer than that of blood.

Circulatory System Circulatory System - Anterior View. The circulatory system is responsible for transporting blood throughout the body. The circulatory system includes the heart, arteries, arterioles, capillaries, venules and veins. The system is responsible for delivering oxygen and nutrients to organs, tissues and cells of the body, and for removing carbon dioxide and other waste products. The heart is the central pump for the system.

Volvox (Protists) The phylum Chlorophyta (green protists) includes colonial and singular species that help recycle the carbon of aquatic ecosystems, and like plants, can convert carbon dioxide, water and solar energy into carbohydrates and dissolved oxygen. Also in similarity to plants, the chlorophytes, including Volvox, feature cellulose cell walls and chloroplasts.

- Solar Covers are a complete waste of time and money. They are good for retaining the heat and preventing evaporation which happens to be the number one cause of heat loss for a pool. But for raising the temperature of the pool, they are a watse of money and not worth the cost.y pool is an L shape so it was always a hassle winding it up. Like JohnT says-Solar covers are very very good for keeping heat in a pool! During the last couple of weeks you could see the pool water evaporating causing both heat loss and water loss.

- The circulatory system comprises of the heart, the lungs and the  blood vessels. The main objective of the circulatory system is  transporting oxygenated (rich saturation of oxygen) blood around  the body.he  blood then travels to the left atrium by the pulmonary artery and  then to the left ventricle. The blood leaves the heart by the aorta  to the other parts of the body.. The circulatory system is the organ system that carries substances around our body. There is no such thing as a circulary system.

An average adult has 5 to 6 quarts (4.7 to 5.6 liters) of blood, which is made up of plasma, red blood cells, white blood cells and platelets. The heart is a muscular organ with four chambers. Located just behind and slightly left of the breastbone, it pumps blood through the network of arteries and veins called the cardiovas- cular system. The systemic circulation is a major portion of the circulatory system. The network of veins, arteries and blood vessels transports oxygenated blood from the heart, delivers oxygen and nutrients to the body's cells and then returns deoxygenated blood back to the heart.

Respiratory and circulatory systems Circulatory system. The circulatory system contains the heart and the blood vessels and moves blood throughout the body. Our body has about five litres of blood continually travelling through the circulatory system. All our circulatory organs work together, forming a very efficient pipe network for our bodies.
