to live‚ they take the necessary O2 from the atmospheric air. The O2 is transferred from the blood to all cells of the body and serves for oxidation of nutrients for example glucose. By oxidize the nutrients released energy‚ which is necessary for the functions of the human body. During oxidation produces CO2‚ which in high concentrations is harmful to the human body. CO2 is transferred from the blood to the lungs‚ where is exhales. The intake O2 and the parallel elimination of CO2 in the lungs

Cell: The cell is the basic structural‚ functional and biological unit of all known living organisms. Cells are the smallest unit of life that is classified as a living thing‚ and are often called the "building blocks of life". Discoverer: The cell was discovered by Robert Hooke in 1665. The cell theory‚ first developed in 1839 by Matthias Jakob Schleiden andTheodor Schwann‚ states that all organisms are composed of one or more cells‚ that all cells come from preexisting cells‚ that vital functions

Introduction The purpose of this experiment was to demonstrate osmosis. Osmosis is the diffusion of water across a selectively permeable membrane (Bell et al 2004). Osmosis is the movement of water molecules from an area of high concentration to an area of low concentration (Brown 1999). Hypertonic is the solution with a higher salt concentration. Hypotonic solution is the solution with the lower salt concentration. My hypothesis is that the potato core will increase in size. When the solution is

The Red Panda comes from the family of Ailuridae and its scientific name is Ailurus Fulgens. The Red Fox‚ whose scientific name is Vulpes Vulpes‚ is from the Canidae family. They are both mammals and are the same size. However‚ the Red Panda and the Red Fox share similarities and differences in their appearance‚ habitat‚ diet‚ behaviour‚ reproduction and status of population. First of all‚ the Red Panda and the Red Fox are quite similar but a little different in their appearance. Like the Red

The Blood Circulatory System The Circulatory system is a system in the bodies of all organisms that moves the nutrients that are needed as well as gases and wastes to and from cells and helps fight unwanted bacteria and other diseases. It also helps alleviate the body temperature to maintain homeostasis‚ which is the property of either an open system or a closed system in a living organism. It brings the body’s cells what they need in order to survive – oxygen and nutrients. The center of the circulatory

Risk factors for cellulitis include: • Cracks or peeling skin between the toes • History of peripheral vascular disease • Injury or trauma with a break in the skin (skin wounds) • Insect bites and stings‚ animal bites‚ or human bites • Ulcers from diabetes or a blockage in the blood supply (ischemia) • Use of corticosteroid medications or medications that

Desalination of Seawater Project Paper The main concept of this Desalination process is reverse osmosis‚ but we will get into that later. Right now what is probably running through your head is what exactly is desalination. To put it simply desalination is the process to make seawater or otherwise undrinkable water safe to consume. This can be accomplished through a variety of methods such as the simplest but one of the ones that requires a lot of money would be distillation. Distillation is commonly

Tell Me About Blood 1.) What is the significance of lower-than-normal hematocrit? Lower-than-normal hematocrit indicates anemia. People with anemia do not have enough hemoglobin‚ which is the oxygen-carrying protein in red blood cells. Iron‚ B12‚ and folic acid deficiencies‚ some medications‚ and pregnancy can cause anemia. There are also more serious causes such as problems with the immune system that cause destruction of red blood cells earlier than normal‚ chronic diseases including
