... a higher concentration to a lower concentration through a semi- permeable membrane until the molecules are evenly distributed. One example of osmosis in our body is absorption of nutrient in our digestive system through osmosis. When the digestive system breaks down the food osmosis helps to absorb the nutrients into the intestine and individual cells. This process occurs in both small and large intestine. However, majority of ... intestine with the lack of salt due to osmosis. The high concentration of the particles in the blood than in the large intestine, water diffuses towards the p...

... as tissues. A tissue is a group of similar cells that preform similar functions. Different tissues form many different tasks. For example, a kind of tissue is made up of cells that produce digestive enzymes in the pancreas, and the cells in an eye respond to light. Most multicellular organisms have four main types of tissues: muscle, epithelial, nerve, and connective. Some tasks in ... a group of organs that work together to preform one function. There are many organ systems in our body. We have a muscular system, skeletal system, nervous system, and circulatory system. Multicellular Or...

... around the matrix. Carbohydrates are a main source and store of energy for plants and animals. They are the best energy source we have and keep the digestive system fit and provide nutrients for the brain and nervous system. They exist in three main forms; mono, di and polysaccharides. However, polysaccharides are the most useful. Glucose is the universal fuel for respiration but cannot ... ...
