Air enters the respiratory system through the nostrils and mouth (External nares) Then the air goes through the larynx and trachea, which is a tube that enters the chest cavity. Then the trachea splits into two tubes, bronchi, which split further into bronchial tubes. Bronchial tubes lead further to the lungs, where they divide in many smaller tubes which connect to tiny sacs called alveoli. The trachea and surfactant perform there function of preparing the air to enter the lungs through cleaning the air and warming it up. (Essentials of Anatomy & Physiology, Chapter 15, 504-511) 2.
Who knew that the pharynx is part of the respiratory and the digestive system? That’s right! The part of the trachea we are using to exit from is called the nasal pharynx. The flap of tissue we can all see ahead of me is called the epiglottis. This piece of tissue either flaps over the trachea or the esophagus, depending upon if we are eating, drinking, or breathing.
Plasma carries food from the stomach to cells but carries waste from the cells to the kidneys and intestine. The body needs lots of haemoglobin because it will combine with the gases; oxygen and carbon dioxide. The red cells carry the oxygen in the arteries and capillaries to cells of the body. One function of the blood is to transport materials within plasma and hemoglobin around the body. Plasma contains hormones, nutrients and waste substances.
Identify three mechanical digestion activities. a. Chewing b. Mixing of food with saliva by tongue c. Churning food in the stomach and segmentation of the intestines 3. Name two feedback loops that regulate digestive system smooth muscle responsible for propulsive and mixing movements. Hormonal feedback loops and neural feedback loops. Neural Regulation of Mechanical Digestion 4.
The food and drink goes into our stomach and from there it is digested, absorbed, then either stored or converted into energy by chemical reactions in our body, therefore food is chemical energy. https://uk.answers.yahoo.com/question Glucose + Oxygen = Carbon Dioxide + Water + Energy In other words, glucose and oxygen are turned into carbon dioxide and water releasing energy. http://purchon.com/chemistry/?page_id=223 The sum of all chemical reactions within a living organism is known as metabolism. The two body systems I am going to explain in detail are Respiratory and Circulatory and their role in producing energy: Respiration Respiration involves breathing. External respiration which is also known as breathing refers to the inhalation of oxygen from the air into the lungs and expelling carbon dioxide from the lungs to the air.
http://www.healthline.com/human-body-maps/tricuspid-valve The Pulmonic Valve: This valve is found between the right ventricle and the lungs. As the deoxygenated blood continues on its journey through the heart from the right ventricle, it makes its exit by way of the pulmonic valve. This structure is a one-way valve with prevents the flow of blood back into the right ventricle once it leaves the heart. http://www.healthline.com/human-body-maps/pulmonary-valve The mitral valve: This valve is located between the left atrium and the left ventricle. As the now oxygenated blood flows back through the left atrium, it does so under increased pressure.
The respiratory and circulatory systems work together to deliver oxygen to cells of the body (the lungs through air exchange, and the circulatory system by delivery of hemoglobin containing red cells to the capillaries where oxygen is released into the tissues) and removal of carbon dioxide. The circulatory system delivers nutrients absorbed through the walls of the small intestine to other organs (such as the liver, muscles, brain, heart), and delivers oxygenated blood to the digestive system. You breathe in oxygen into your lungs. The oxygen diffuses across the thin walls of the alveoli in the lungs and the thin walls of the blood vessels in the lungs into the blood stream. Here it attaches to the hemoglobin molecules inside red blood cells.

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. Haemoglobin is a protein in red blood cells that enables the cells to carry oxygen, and Myoglobin is an oxygen-binding protein found in heart and skeletal muscles. The metabolism is tied to the respiratory system because it is responsible for providing the oxygen to cells around the body. Digestive system: The digestive system is a group of organs consisting of the mouth, pharynx, oesophagus, stomach, liver, gall, bladder, / ileum and colon; that aid in ingestion, digestion, absorption and defection. The digestive system breaks down the chemical components of food, with fluid, into tiny nutrients which can be absorbed to generate energy.
Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use. * Esophagus Located in your throat near your trachea .and it is a long tube that runs from the mouth to the stomach It uses rhythmic, wave-like muscle movements (called peristalsis) to force food from the throat into the stomach. This muscle movement gives us the ability to eat or drink even when we're upside-down. * Stomach The stomach is a hollow organ, or "container," that holds food while it is being mixed with enzymes that continue the process of breaking down food into a usable form. Cells in the lining of the
