The Circulatory System The Circulatory System is designed to deliver oxygen and nutrients to all parts of the body and pick up waste materials and toxins for elimination. This system is made up of the heart‚ the veins‚ the arteries‚ and the capillaries. Circulation is achieved by a continuous one-way movement of blood throughout the body. The network of blood vessels that flow through the body is so extensive that blood flows within close proximity to almost every cell. Heart The heart

What are the shapes and designations of the f orbitals? The exotic‚ complex f orbital shapes are rarely shown in textbooks. General (and organic) chemistry traditionally focuses on the lighter elements‚ but the forbitals aren’t occupied in the ground state until element 58 (cerium). Even for elements beyond cerium‚ the f orbitals are deeply buried beneath the valence shell and they rarely play an important role in chemical change or bonding. However‚ the orbital shapes can be useful in interpreting

Each step in digestion requires energy‚ and thus imposes an “overhead charge” on the energy made available from absorbed substances The major part of digestion takes place in the

Digestive System: As with any system we are learning in this course‚ the structural anatomy and functions of each are the basis of your learning. Otherwise known as the alimentary canal‚ the best way to learn the digestive system structures and their functions is to follow some food through the process from beginning to end. Where does the food go? As food enters the mouth‚ both mechanical and chemical digestion begins. First the food is physically broken down by the mechanical process

The purpose of this essay is to research and evaluate the digestive system effectively and extensively. Then describe the differences and indifferences of three different organisms in relation to their digestive system. The three organisms that have been chosen are the human‚ for comparative purposes‚ the Goliath Bird Eating Spider and the Cobra Lily carnivorous plant. The Human Digestive System Digestion is the breaking down of substance in the body‚ into an easier form of which it can be absorbed

Digestive system disorders Digestive system disorders can cause a lot of discomfort. Symptoms can include gas‚ diarrhea‚ constipation‚ cramps‚ nausea and vomiting. These common symptoms can have very different causes. These kinds of symptoms can make digestive disorders hard to diagnose. Celiac disease Celiac disease occurs when the body’s immune system reacts to a type of protein called gluten. If a person eats food that contains gluten‚ the immune system will gradually damage the lining of

Biology Mammals Grazing Herbivore: Herbivores digestive systems can consist of one of two types of insides‚ it can be a foregut fermenter where the Foregut Fermeters has two parts (a tubiform and a sacciform fore stomach) containing lots of microbes. The stomach is bigger than that of a hindgut fermenter considering its usually a bigger animal‚ the stomach has an extra chamber to help devour glucose from the cellulose (the herbivores diet is largely cellulose and is broken down by the microbes)
