Example? Because plant cells have tough cellulose cell walls and herbivore are not able to digest‚ they use micro- organisms that live symbiotically to break down cellulose in fermentation process into nutrients | Fore-

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 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

The cardiovascular system is the movement of blood being permitted around the body to vital organs and muscles with the components of the heart‚ blood‚ and blood vessels combining together to make the cardiovascular system work. The cardiovascular systems is vital in the human body as it promotes the body’s delivery system for blood being pumped around the entire body for survival. The respiratory system also has importance in the body as it is the system to transport air into the lungs to aid the

Human Digestive System The digestive tract is a series of hollow organs through which food passes: mouth‚ pharynx‚ esophagus‚ stomach‚ small intestine. Each portion is specialized for one or more aspect of the three major functions of the digestive system the secretion‚ digestion‚ and absorption. Accessory organs such as salivary glands‚ liver‚ gallbladder and pancreas have duct that lead into the digestive tract and thus support digestive function. Digestion is defined as the mechanical

Human Body May 30‚ 2010 The Cardiovascular and Muscular Systems Organ system is a group of organs that work together to perform a certain task. Humans have a variety of systems due to the complexity of the species’ organism. The human body consists of biological systems‚ that consist of organs‚ that consist of tissues‚ that consist of cells and connective tissue. Although an organ has a specific function‚ organs also function as part of a group. The organ system is the organizational unit
