Medullary Respiratory Center Analysis
Furthermore, the regulation of the respiratory center can be modified in response to inputs from other brain regions, receptors in the peripheral nervous system, and other factors (chemoreceptors, voluntary control, etc.) in order to preserve the homeostasis of breathing. The respiratory center comprises of dispersed clusters of neurons located near the brain stem that modify the breathing muscles of the thorax by transmitting nerve impulses from centers in the brain which signals either contraction or relaxation (absence of nerve impulses). The respiratory center can be divided into two sections: the medullary respiratory center in the medulla oblongata and the pontine respiratory group (or pneumotaxic area) in the pons. The medullary respiratory

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.
President And CEO Of Ventria Bioscience
760 Words | 4 PagesScott Deeter was the president and CEO of Ventria Bioscience, a Sacramento, California-based biotechnology firm that developed an innovative process to produce pharmaceutical proteins in the seeds of genetically modified rice, which was used to create a medicine to lessen the severity of childhood diarrhea. However, Scott Deeter and Ventria faced many problems. One being that the company was unsuccesful in getting the California Secretary if Agriculture to grant them the necessary permits in order to plant the 120 acres of bioengineered rice to begin commercial-scale production. Another being that many different organizations opposed what they were doing, such as, environmentalists, food safety activists, consumer advocates, and rice farmers. There is also a risk of contamination, and genetically altered plant possibly cross-breeding with wild plants.
How To Maintain Homeostasis
1856 Words | 8 PagesHomeostasis 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.

Background Information Cell Respiration refers to the biochemical process conducted by the cells of an organism that combines glucose and oxygen to produce energy in the form of ATP, along with two by-products, water and carbon dioxide. The equation representing this chemical reaction is shown below. C6H12O6 + 6 O2 6 CO2 + 6 H2O
Respiratory Therapy
2352 Words | 10 PagesKaitlyn Finney Respiratory therapy 150 RESPIRATORY DISTRESS AND IT 'S AFFECT ON INFANTS Respiratory distress of the newborn is a very fatal but curable disease. It is a vicious series of events that all lead to severe impairment of the respiratory function. Although it is primarily due to immature lungs the reason the lung maturity is so important is because of the growth of surfactant. Surfactant replacement and mechanical ventilation are both very helpful therapies for infants with Respiratory distress syndrome however the best method is the prevention of prematurity. The purpose of this paper is to enlighten the reader about this devastating disease and the successful therapies we respiratory therapists use to reverse and care
Spirometry Lab Report
367 Words | 2 PagesSpirometry is one method that we used to measure the volumes difference in amount of air breathed in or out and how quickly the air is inhaled and exhaled from the mouth while breathing through a mouthpiece. In this present study, we measured the lungs volumes during normal breathing and with the maximum forced expiratory flow rates. For this experiment, we use the Phipps and bird wet spirometer to measured Tidal Volume (TV), Inspiratory Reserve Volume (IRV), Expiratory Reserve Volume (ERV), and Vital Capacity (VC). The purpose of this experiment is to determine various lung volumes for an individual and to compare them to average lung volumes. Participant (n=1) breathed into the Phipps & bird wet spirometer.
Breathing And Cellular Respiration Essay
808 Words | 4 PagesBreathing is the transportation of oxygen across from the air in the lungs to circulating red blood cells (erythrocytes) which pass on the oxygen onto cells which require and utilise the oxygen, during aerobic respiration, to produce energy in the form of ATP. This biochemical reaction produces carbon dioxide as a waste product, and it is transported, using the red blood cells (RBCs), back to the lungs and exhaled. Figure 1 shows the relationship between breathing and cellular respiration, with the two connected by the gas carrying red blood cells. Notice the requirement for oxygen by the cells to produce energy in the equation at the top – breathing is how this requirement is fulfilled, whilst venting the waste products from respiration

In humans, two of these sensors are the subfornical organ (SFO) and the vascular organ of the lateral terminalis (OVLT), both located near the hypothalamus. These clusters of neurons contain specialized surface proteins called osmoreceptors capable of sensing changes in the concentration of sodium and chloride ions. If the blood becomes too concentrated, the SFO and OVLT activate hypothalamic neurons, ultimately culminating in the sensation of
Nervous System Research Paper
973 Words | 4 PagesIt consists of bundles of nerve fibers that join the lower parts of the brainstem and the spinal cord with the higher parts of the brain. The midbrain is the center for auditory and visual reflexes and plays a role in controlling wakefulness of the brain. The pons means ‘bridge’ in Latin, therefore it connects the midbrain to the medulla and cerebrum. It plays as an important role in controlling the rate and length of respiration. The medulla oblongata is an extension of the spinal cord as it lies just inside the cranial cavity above the large hole in the occipital bone called the foramen magnum.
The Lungs: A Short Story
287 Words | 2 PagesAs soon as she woke up, Max felt a triggering pain through her head. She instantly tried to move her hands to her forehead, but quickly found out they were tied to the chair she was sitting in. “What the…” she thought out loud as she was finally looking around, only to recognize the place a few moments later. Multiple lights were directed at her, and she could see the same camera she had seen Mr. Jefferson use so many times on the table that was facing her. Almost like he liked the idea of sitting on the couch and just staring at his poor victims.
Breathing Rate Lab Report
203 Words | 1 PagesYour breathing rate is regulated by neural and chemical mechanisms. Respiration is controlled by neural messages from the brain to nerves that stimulate respiratory muscles. The main respiratory muscle is the diaphragm, which is controlled by the phrenic nerve. The rate, at which the nerves are sent messages from the brain, is controlled by the level of oxygen and carbon dioxide in the blood. There are chemoreceptors in the brain and the heart that sense the amount of oxygen, carbon dioxide and acid present in the body.
Mammal Gas Exchange
917 Words | 4 PagesDiffusion rates across the membranes occur at rapid rates because the gas exchange membranes are only 0.5µm thick, and because the lung capillaries are situated very closely to the alveoli which also allows diffusion of gases back and forth to occur across a tiny space. To prevent the lungs from collapsing as a result of the atmospheric pressure, the lungs are protected by a rib cage which provides protection from injury and allows for differences in the internal and external air pressures to be
Total Lung Capacity Essay
785 Words | 4 PagesThe 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).
