Circulatory Vs Mechanical Digestion Research Paper

The digestive system absorbs the minerals and nutrients from the foods that have been eaten. The break down of food beings in the mouth, where the

The esophagus receives food from the mouth after swallowing and then delivers it to the stomach. The stomach holds food which it is being mixed with enzymes which continue the process of breaking down the food into a useable form. When the contents of the stomach are processed they are released into the small intestine. In the small intestine food is broken down by enzymes released from the pancreas and bile from the liver, the food is moved through and mixed with digestive secretions. The small intestine is made up of three segments the duodenum, jejunum and the ileum, the jejunum and the ileum are mainly responsible from the absorption of nutrients in to the bloodstream. These contents start out semi-solid and end in a liquid form after passing through the organ. Water, bile, enzymes and mucous change its consistency, one the nutrients have been absorbed it then moves onto the large intestine. The large intestine connects to the rectum and is specialised in processing water so that emptying the bowels is easy.

When food is ingested it travel along the digestive track in to the stomach. where it is broken down in to nutrients in order to be absorbed by the small intestine and inters the blood stream to travel through the circulation to all body cells. One of the nutrients is glucose. When the glucose concentration rise it get detected by the beta cells in the pancreas

First the air that’s breathed in travels down the trachea, into the lungs, through the bronchioles and into tiny air sacs called alveoli. The oxygen in the alveoli diffuses into the capillaries, where there’s a lower concentration of oxygen. The thin walls of the capillaries allow the oxygen to diffuse through into the blood. The circulatory system then carries the blood around the body, supplying cells with the oxygen required for energy; allowing them to function. Glucose is also needed, which comes from the digestive system. Glucose is made from the sugary or starchy foods consumed. It start off in the mouth where the salivary glands produce saliva, which contains amylase which breaks down the sugars and starch. It then travels to the stomach, where it’s mixed with other enzymes and fluids, becoming a mixture known as chyme. Chyme, then travels to the small intestine where there are tiny, finger-like structures called villi on the surface walls of the intestine. Villi, are one cell thick making it easy to absorb particles, such as glucose, into the blood from the chyme which is passing through the small intestine. Once in the bloodstream, the circulatory system transports the glucose to cells to be used for energy.

The circulatory system and the respiratory system work closely together to ensure that organ tissues and systems receive enough oxygen. Oxygen is required for cellular functions such as cell respiration. This is so the body’s organs and cells can work at fully; it is done by releasing chemical energy with in stored foods. The air breathed in and held in the lungs is transferred to the blood. The blood is circulated by the heart, which pumps the oxygenated blood from the lungs to the body organs and returns with deoxygenated blood.

Digestion starts in mouth and it is going through several steps. Teeth which are a Mechanical digestion start tearing and crushing the food down into small pieces so that the food will smoothly run down our throat. The salivary glands are located underneath the back of our tongues and that’s what is creating our saliva. The saliva is the Chemical Digestion is helping soften the food in the mouth so it is easy to swallow. Also saliva is the first out of several chemicals that is breaking the food into smaller bits. The tongue is the muscle that works with the food and saliva to form something similar to balls that can be swallowed. Also tongue contains taste buds so that we know if the food is salt, sweet, sour or bitter. Esophangus is a simple transportation tube that is joining the throat with stomach. When swallowing we are closing a trap door in our throats called the epiglottis. By closing this trap we are preventing the food prom going to trachea and into our lungs. Also Food moves down the esophangus using muscles not gravity. Stomach is the first stop after the Esophangus. When the food gets into stomach the stomach uses chemicals to try to make the food smaller. These chemicals are called gastric juices and they include hydrochloric acid and enzymes. (Enzymes are

Your body requires energy in order to be able to perform tasks. Energy comes in many different forms. They are chemical, light, sound, heat and mechanical. You can get energy from different food substances i.e. glucose, fatty acids, sugars and amino acids. To be able to get the energy from these food substances energy needs to be released with oxygen. This is known as aerobic respiration. The role that energy plays in our body is the process of moving molecules in and out of our cells while breaking down the larger molecules and building new molecules. The cardiovascular system transports oxygenated blood around the body and to the cells. It will then collect the deoxygenated blood which is ready for the excretion from the cells. The cardiovascular system will deliver the nutrients oxygen and glucose via the blood stream. Oxygen is need for aerobic respiration to occur. The cardiovascular system will pump oxygen and nutrients carrying blood throughout the body. The glucose molecules that are carried by the blood are transported into the cells. Along with the oxygen that is diffused into the cells they are used in respiration to produce ATP. The respiratory system is responsible for bringing in oxygen as well as using it to burn the nutrients that we need for energy. The respiratory system contains alveoli which allow the diffusion of oxygen into the blood stream

Answer 2: The respiratory system functions in the exchange of gases with the outside environment. Oxygen is inhaled through the nasal cavity or the mouth, and it travels to the alveoli in the lungs. There, the capillaries exchange the oxygen for carbon dioxide. The oxygenated blood flows back to the heart from the lungs. It enters the left side of the heart and is delivered to all the body tissues via the aorta. In the capillaries of the body tissues, oxygen is exchanged for carbon dioxide. This deoxygenated blood flows back to the right side of the heart and then to the lung. In the capillaries that run across the alveoli, carbon dioxide is exchanged for oxygen that has recently been inhaled. The carbon dioxide will then be exhaled through the mouth and nasal cavity.

Cells depend on the oxygen and nutrients supplied by the blood to do their various jobs-from the heart muscle cells that keep your heart pumping to the brains cells that keep you thinking and coordinating your countless activities.

The respiratory system is a complex organ structure of the human body anatomy, and the primary purpose of this system is to supply the blood with oxygen in order for the blood vessels to carry the precious gaseous element to all parts of the body to accomplish cell respiration. The respiratory system completes this important function of breathing throughout inspiration. In the breathing process inhaling oxygen is essential for cells to metabolize nutrients and carry out some other tasks, but it must occur simultaneously with exhaling when the carbon dioxide is excreted, this exchange of gases is the respiratory system's means of getting oxygen to the blood (McGowan, Jefferies & Turley, 2004).

Most sugar digestion happens in the intestines. Intestinal enzymes complete the sugar breakdown and then it is absorbed into the bloodstream, providing us with energy. Before watching the video, I had dinner. I got chicken breast, marinated Brussel sprouts, two small red baked potatoes, and apple juice.

The digestive system is very important in digesting food and breaking it down so it can be digested easily. The digestive system turns food into energy. Throughout the process there are nutrients which are absorbed. There are many things that contributed to the digestive system such as the mouth which produces saliva which helps to break down food and nutrients such as carbohydrates with the help of an enzyme called amylase. The major food groups which are called macro nutrients include carbohydrates, proteins and fats. All of these nutrients play an important role in the body. There are also many micro-nutrients which include vitamins and minerals which provide the body with health and well-being. The digestive system is made up of the mouth, which includes the teeth (the teeth are used to cut and grind food into smaller pieces, they contain blood vessels and nerves), tongue (the tongue is a muscle that has a rough surface including the taste buds), salvia glands (they produce salvia which moistens the food to make is easier to digest), the pharynx (this helps the food travel to the stomach, the pharynx also plays an important role in the respiratory system. It also contains 2 different flaps to separate the 2 functions), esophagus (this connects the pharynx to the stomach and transports chewed food to the stomach), stomach (this is a muscle that is

The Respiratory System is designed to get oxygen into the body and carbon dioxide out. Once external respiration takes place exchanges of gases between outside air (atmosphere), to inside blood and cells takes place. Internal respiration continues from this exchanging of gases from blood and tissue fluids. Cellular respiration further continues the process and helps fuel the production of ATP which is the body’s essential energy source. (Johnson 2010 Chp.15)

The mechanical digestion also known as the physical process of breaking down the food with no introduction of chemical. The teeth chews and break down the food in the mouth and is the first step in the digestion process known as ingestion. The food is moves from the mouth down into the alimentary cannel as soon as the surface area of the food is for a swallowing process and is ready for mobility. Inside the mouth carbohydrates starts digestion through the salivary amylase which also incorporates the mechanical and chemical digestion,

The digestion starts here as soon as you take a bite of your food. By chewing your food it breaks the food into pieces so that is easy to digest, and the saliva mixes with food to begin the process of breaking it down into a form that your body can take. The throat also known as the (pharynx) is the next stop and from here; the food goes to the esophagus or swallowing tube. The esophagus is a muscular tube extending from the pharynx to the stomach. By means of a series of contractions, called peristalsis, the esophagus delivers food to the stomach.
