Essay On Human Body

The food that cannot be broken down is called feces. Feces is stored in the rectum until it is expelled through the

The fact that it has a large surface area allows the water to be efficiently absorbed. Salts are released from the partially digested food. The omasum moves food from the reticulorumen to the true stomach (abomasum) where acid digestion takes

The food then travels into the oesophagus. Your oesophagus is located near your trachea (windpipe). The epiglottis separates the nasal cavity and the lower airway from the passage of food whilst swallowing. The contractions of the muscles in your oesophagus push the food down your oesophagus and into your stomach. Your stomach is a hollow organ that holds food whilst it is being broken down by the enzymes.

Connective tissue varies widely in appearance and function, but all forms share three basic components which are extracellular protein fibers, specialized cells, and a fluid known as ground substance. The combination of the extracellular fiber and ground substances produces the matrix that surrounds the cells. The functions of connective tissue are to establish a structural framework for the body. Secondly, it transport fluids and dissolved materials.

The diet requires a large consumption of carbs and protein so it is typical for bodybuilders and wrestlers to comply with IIFYM; however, all athletes could follow IIFYM. The key concepts to remember are, knowing how many calories your body burns in an average day (TDEE), eating 10-20% less calories than your TDEE, and splitting the calories between carbs, protein, and fats in a way that encourages fat loss with no loss of daily energy. However, the IIFYM diet does not take heart or brain health into consideration. The casual effect of flexible eating foods such as fast foods could potentially cause health risks for your body.

In every cell there are three main parts: the nucleus, the cytoplasm, and the cell membrane. The nucleus is a spherical body usually located near the center of the cell that contains the genetic code of the cell and its purpose is to serve as the control center. Cytoplasm is the fluid medium for the many molecules and organelles the cell has. The cell membrane is the outer layer that separates the cell from its environment and controls what enters and leaves the cell.

Digested molecules of food, as well as water and minerals from the diet, are absorbed from the cavity of the upper small intestine. Most absorbed materials cross the mucosa into the blood and are carried off in the bloodstream to other parts of the body for storage or further chemical change. As already noted, this part of the process varies with different types of nutrients. 5. 2) Page B13, and #1-4 1.

Unlike the human digestion system, crayfish have a rather simple system. Starting with the mouth, food is ingested and passed into the cardiac stomach via the esophagus. In this first stomach food is stored until it is passed into the pyloric stomach; filled with small “teeth” like structures. Once ground the food is handed out to the intestine, where nutrient is absorbed into the blood vessels and taken around the body. After the intestine, the excess waste is removed through the anus.

In this section I will explain how two of the body systems interrelate to perform a function. My two body systems are the cardiovascular system and the digestive system and how they work together to enable food to be digested. First of all, the digestive system works by passing food through the human system, whilst breaking it down and absorbing nutrients. The circulatory system transports the oxygen and other compounds through our bodies. These two work together to process and circulate nutrients so our cells can use them for fuel.

The digestive tract also produces a protective mucus that lines the stomach. The stomach stores food and begins digestion of proteins. During digestion, the stomach

The mitochondria do this by taking the energy from food that the cell takes in or creates. After they collect the chemical energy the mitochondria convert it into a more accessible energy source, ATP. Golgi Complex: The Golgi complex prepares, packages and distributes substances out of the cell. The reason for this is the cell wants to stay even with the entire body. If 60% of the water is in the cell, the Golgi complex is going to get rid of 10% of the water to even it out.

The stomach is a very important part of the digestive system. It is a j- shaped muscular organ that acts as a bag or sac to collect churn food with digestive juices. When the stomach is filled with food the rugae stretch out, and disappear. The food mixes with hydrochloric acid and other gastric juices to form a liquid mixture called chyme, which then passes through the remaining portion of the digestive system. So this means to me that when you eat something it goes to the stomach and is mixed with acids that breaks it down and dissolves the food.

What are Tissues? Tissues are comprised of individual cells and are one of the main building blocks of an organism. All the cells in a tissue do the same job.

Unit 5 Anatomy and Physiology for Health and Social Care P4 Explain the physiology of two named body systems in relation to energy metabolism in the body The two body systems selected in relation to energy metabolism in the body are the digestive system and cardiovascular system. The digestive system breaks down foods and the cardiovascular system enables absorption and usage of the food. The term energy metabolism in the body relates to chemical reactions that that maintain cells and organisms. It is divided into two categories: catabolism is the breakdown of molecules to obtain energy and anabolism the synthesis of all compounds needed by the cells.

Introduction: Dissections are performed on preserved animals donated specifically for science education in order to provide a hands-on experience to observe and study anatomy of an animal in three dimension, unlike a textbook, and how the organ systems are interconnected. In this particular dissection a fetal pig was used because the organs present in a pig, and their position in the body are similar to those of humans which provides insight on how human organs systems work overall and why they are essential to life. The purpose of our experiment was to focus on the external, digestive, cardiovascular, respiratory, and excretory systems of the fetal pig to understand how theses system work together in order to sustain life.
