The human anatomy is the scientific study of the morphology of the adult human. A digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. The main functions of the mouth include mastication, tasting foods, and speech. The salivary glands are accessory organs that produce a watery secretion known as saliva.The body also uses saliva to lubricate food as it passes through the mouth, pharynx, and esophagus. The esophagus carries food, liquids, and saliva from the mouth to the stomach. Partial digestion takes place in the stomach. The main function of the small intestine is an absorption of nutrients and minerals. The major function of the large intestine is to absorb water from the remaining indigestible food matter and transmit the useless waste material from the body.
The excretory system maintains water, ion, and nitrogen balance within the body and eliminates wastes. The reproductive system creates new individuals of a species. Both the excretory and reproductive systems are under endocrine control but are also influenced by the external environment. The kidneys extract waste from blood, balance body fluids and form urine. The kidneys filter the blood to remove wastes and produce urine.

The function of the nasal cavity is to warm, moisturize, and filter air entering the body before it reaches the lungs. The pharynx connects the nasal and oral cavities with the larynx and esophagus. The larynx houses the vocal cords and manipulates pitch and volume, which is essential for phonation. The trachea has the vital function of providing air flow to and from the lungs for respiration. The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled. The diaphragm is the primary muscle used in the process of inspiration or
It also helps provide oxygen to the body. External respirations is when you breathe in through your lungs and carbon dioxide exhaled out. Internal respirations is what you inhales goes from the lungs back to the heart. 4. Describe eight signs and/or symptoms of the respiratory system.
The kidneys of the fetal pig can be located on both sides of the spine behind the abdominal organs. The kidneys’ are a vital part in the process of removing urine from the body. The path that urine takes to exit the body is very specific. First, the urine is in the kidney. Next, the urine goes into the ureters, followed by the bladder and urethra before exiting.
Hyaline membranes help to the development of fibrosis and atelectasis (collapse) essential to decrease in gas exchange capability and lung dysfunction. These changes cause the lungs to become stiff, patient work hard to inspire. Hypoxemia and the stimulation of juxtacapillary receptors in the stiff lung parenchyma leading to increase respiratory rate and decrease in tidal volume. Breathing irregular increase carbon dioxide removal,
The proper functioning of one system relies on the proper functioning of the other system. In other words, the digestive system needs to be in good working order to support the functions of the cardiovascular system. An example of the digestive and cardiovascular systems interrelating is: the first step in digestion of fat is to dissolve it into the intestine where bile acids produced by the liver dissolve the fat into fatty acids and cholesterol. The bile acids join with the fatty acids and cholesterol and vessels then carry the changed fat to the veins of the chest, and the blood carries the fat to storage in different parts of the body.
This organs help get rid of the wastes from the body as either urine or
Homeostasis is the body's method of keeping internal stability no matter what external influence disturbs its normal functioning (Anna, 2011). And the respiratory system is one of the systems in the body that helps to maintain homeostasis by maintaining pH and regulating gas exchange. The main function of this system is take in oxygen and get rid of carbon dioxide. This system has external respiration and internal respiration. External respiration is a mechanical process that exchange of gases in and out of the body, while internal respiration is the chemical process that breaking down nutrients with oxygen to produce energy.
The first three organs listed are used to move and/or absorb food,
The potential space between the instinctive and parietal pleurae is known as the intrapleural space. The intrapleural and intrapulmonary pressures fluctuate amid ventilation. The intrapulmonary pressure is subatmospheric amid inspiration and more prominent than the atmospheric pressure amid expiration. Pressure changes in the lungs are delivered by varieties in lung volume, as per the opposite relationship between the volume and pressure of a gas portrayed by Boyle's law. The mechanics of ventilation are affected by the physical properties of the lungs.
The digestive system is responsible for chemically and mechanically breaking down food and includes organs such as, mouth, esophagus, stomach, small intestine, rectum, anus, and additional accessory organs. These organs all aid in the breakdown of food. Food is broken down mechanically by chewing and churning in the stomach, and chemically by acidic enzymes in the stomach and in the small intestine which receives enzymes from the pancreas that are specifically designed for the breakdown of nutrients. Once the food and nutrients are broken down, the excretory system removes whatever the body decides is waste by filtering blood in the nephrons of the kidneys and turning it into urine which is then collected in the bladder and removed from the body when the bladder is
The Digestive System The digestive system is a system consisting of the mouth, oesophagus, stomach, gallbladder, small intestine, large intestine, the rectum and the anus. The functions of the digestive system are: • To break down food particles into molecules for digestion • To absorb into the bloodstream the small molecules produced by digestion • To eliminate un digested and unabsorbed foodstuffs and other waste products from the body The full digestive process begins at the mouth. The food enters the mouth and is chewed.
“The esophagus is a muscular tube that connects to the mouth, to the stomach that makes food easier to swallow and move along. The stomach is a j-shaped muscular pouch holds all the food that the body swallows. The gallbladder is an organ that stores bile passing through a tube from the gallbladder to the small intestines. Bile a
Now the digestive system is what helps us get some of the energy we need but the muscular system is what moves the food around our digestive track an out of our bodies. One of the biggest diseases that the muscular system has to deal with is the Iron Maid diseases. This malfunction is where the makeup of your muscles is remade and when they are impacted in a forceful way they turn to bone. This make the patient unable to move and it very slowly creates a pressure on their chest and stomach and makes them unable to do anything ever again.
The heart may have the sinoatrial node (SA node) to trigger contraction, but in order for us to breath our nervous system has to signal for us to begin the process of ventilation (breathing). Our brain stem has three parts to it, but only the pons and medulla oblongata play a key role in breathing. The medulla helps set the respiratory rhythm by receiving and sending impulses to a bundle of neurons called the ventral respiratory group to the phrenic nerve to bring about contraction in the diaphragm and external intercostal muscles. All this only happens though due to the sensors of the chemoreceptors. The chemoreceptors located in the medulla and carotid and aortic bodies detect a rise in carbon dioxide (CO2).
The digestive system is located around the stomach area. Along with the digestive system, many other organ systems all work together to create an organism. An example of this would be if a person eats a sandwich and then goes for a run. During the run, the circulatory system helps the body breathe, the muscle system helps the bones move, and all the while the digestive system digests the food. Later on, the excretory system gets rid of the waste, or food that the body can’t use for nourishment.
The nerve supply also comes from her celiac plexus innervating the liver mixture of sympathetic and parasympathetic fibers. These ribs reach the liver by the hepatic artery. Liver Physiology The liver performs many functions in the body such as: • Production of bile: The liver excretes bile to the bile duct and thence to the duodenum. Bile is necessary for digestion of food.
