The Circulatory System The Circulatory System consists of the heart‚ blood and blood vessels. It performs many vital functions. It plays an important role in respiration. The circulatory system is also important in nutrition‚ in the removal of wastes and poisons‚ and in several other body processes. The functions are; Transport gases‚ like oxygen from the lungs to cells around the body and carbon dioxide from the cells to the lungs. Transport nutrients like glucose. Transport wastes from cells

Circulatory System SCIE 206-1004A12 April Nixon 9/19/2010 The heart and lungs are both found in the circulatory system. There are also blood vessels which play an important part in the human body’s circulatory system. The heart serves as a pump; the blood vessels‚ which carry the blood throughout the body; and lastly‚ the blood‚ which is a vital component for the basic functioning of the human body‚ and which is processed after the intake into the human lungs from the atmosphere.

Circulatory System Composition of Blood Red Cells -These are tiny‚ disc-like cells which do not have nuclei. -In their cytoplasm is the haemoglobin‚ a protein combined with iron. Haemoglobin combines with oxygen in places where there is a high concentration of oxygen‚ to form oxyhaemoglobin. -Oxyhagemoglobin is unstable compound. It breaks down and releases its oxygen in places where oxygen contentration is low. White Cells -They undergo a process of matruation and development in the

The Evolution of Fish: Vertebrates Begin If you were to look at the oceans 530 million years ago‚ you would be amazed by the wild array of creatures thriving in the waters. The seas abound with robust rainbows of corals and starfish. Huge schools of jellyfish pump through the waters while the sea floor is alive with a variety of mollusks and crustaceans. Life would likely have appeared to be as diverse as it could get. Then in the waters off the coast of China appeared a new‚ tiny little creature:

1. Within the circulatory system the liver has a unique anatomic location in that it effectively filters all blood coming from the intestinal tract by way of the portal vein before it is pumped to the general circulation. The liver often sees drugs at their highest concentrations‚ since it is the first organ perfused by blood containing the drug after absorption from the intestinal tract. Approximately 10-15% of total blood volume can be presented to the liver at any given time. The entire absorbed

About the circulatory system The circulatory system is an organ system; the main purpose of the circulatory system is to deliver nutrients such as amino acids and electrolytes. Move gases‚ hormones‚ blood cells‚ etc to and from cells in the body to fight diseases. Lastly it removes waste products. What helps to control the flow of the blood around the body are the vessels and muscles made up of the circulatory system. This process is called circulation. The heart‚ arteries‚ capillaries and veins

closed circulatory system of some mollusks and all higher invertebrates and the vertebrates is a much more efficient system. Here blood is pumped through a closed system of arteries‚ veins‚ and capillaries. Capillaries surround the organs‚ making sure that all cells have an equal opportunity for nourishment and removal of their waste products. However‚ even closed circulatory systems differ as we move further up the evolutionary tree. One of the simplest types of closed circulatory systems is found
