The monosaccharides are them absorbed into the bloodstream. From blood, the monosaccharides are carried to the liver and converted into glucose and then stored in the liver or sent back out to feed the individual cells. Any fiber continues to the large intestine where some is metabolized by bacteria, but most is excreted. Fat From the mouth, chewing food breaks it down to a degree. The lingual lipase, found in saliva, plays a minor role in breaking down fat.
The diaphragm is essential for the gas exchange process. The diaphragm pumps carbon dioxide out to the lungs and pumps oxygen in the lungs. When the diaphragm relaxes, carbon dioxide releases from the lungs. When the diaphragm contracts, oxygen is pulled into the lungs. (Essentials of Anatomy & Physiology, Chapter 15, 514, 518-521) 3.
Stomach The stomach holds food while it is being mixed with enzymes that continue the process of breaking down food. Cells in the lining of the stomach secrete a strong acid and powerful enzyme that are responsible for the breakdown process. When the contents of the stomach are successfully processed, they are released into the small intestine. Small intestine The small intestine has 3 parts; the duodenum, jejunum, and ileum — the small intestine breaks down food using enzymes released by the pancreas and bile from the liver. It moves food through and mixing it with digestive secretions from the pancreas and liver.
Diffusion helps to remove dissolved carbon dioxide from the blood and into the expelled air from lungs. Diffusion is the molecules (gas or liquid) moving from high concentration to low concentration. M1: Discuss the role of energy in the body. Our bodies need energy to work properly. The energy we need and use comes from the type of foods we eat.
Support the absorption of carbohydrates and proteins B. accept chyme from the stomach and complete digestion C. Absorbs B12,bile salts, fluids and electrolytes and secretes enzyemes that further break down carbohydrates and proteins 14. Slow the passage of food along the intestines and increase surface for absorption 15. A. Absorbs B12,bile salts, fluids and electrolytes and secretes enzyemes that further break down carbohydrates and proteins B. Creates a space for liquids to empty into C. Move waste up and out of the body D. Absorbs water from stool E. Absorbs water from stool and stores food that will be emptied into the rectumlts F. Moves stool into rectum 16. Secretes pancreatic juice, insulin, glucagon, duodenum, and somatostatin into the bloodstream.
Produces essential proteins and clotting factors for the blood and regulates metabolism and cholesterol. Gall Bladder – Stores bile secreted by liver. Bile is used to help dissolve fats in the small intestine. Pancreas – Functions both as an exocrine gland and an endocrine gland. Exocrine portion secretes digestive enzymes carried to the duodenum.
Unit 5- Anatomy and Physiology for Health and Social care P2-Outline the structure of the main tissues of the body The stomach- The stomach is a muscular organ that is located on the left side of the upper abdomen. The stomach receives all the food from the esophagus, when the food reaches the end of the oesophagus it enters the stomach through a muscular valve which is known as the lower esophagus sphincter. The stomach muscles contract periodically, churning the food to enhance digestion. Phloric sphincter is a muscular valve which opens to allow food to pass from the stomach to the small intestine. Non-striated- There is non striated muscle in the stomach, it helps the digestive system in the process of digestion of food by causing mechanical digestion due to churning action as muscles contract.
The saliva which is contained in the mouth which is produces by the salivary glands begins to digest the food before the food is even swallowed. Saliva and the other chemicals which are produced along the way help speed up the digestive process which is called digestive enzymes. The mouth which is also known as the oral cavity is a specialized organ which receives food and breaks it into smaller pieces. The mouth is changed mechanically when biting and chewing food. In a humans mouth there are teeth and within a human they are four types of teeth which are used for different functions such as the incisor teeth are for biting and are found are the front of the mouth.
The difference is internal respiration happens at the cellular level while external respiration is the actual breaths. 2. What are the key functions overall of the respiratory system? The key functions of the respiratory system is to bring air and blood into the alveolar air sacs so that the air can enter into the bloodstream while the carbon dioxide exits. It also maintains the body’s pH levels and body temperature.
The two body systems I will write about are the respiratory system and the digestive system. Respiratory system: The respiratory system comprises of the nose, mouth, throat, larynx, trachea, bronchi and lungs. The function of the respiratory system is to facilitate gaseous exchange to take place in the lungs and tissue of the body. Oxygen is required by cells to allow various metabolic reactions to take place and to produce energy which is essential to life. Internal respiration involves chemical activities that take place in every living cell requiring oxygen and glycogen to combine to release energy, water and carbon dioxide.
