he pharynx join the nasal depression and the mouth to the larynx and throat. The pharynx dividers are skeletal muscles. The pharynx is at the base of the skull down to the sixth cervical vertebra. The structure of the pharynx helps when playing O2 touch, as we take full breaths amid activity, air experiences in mouth increasingly and afterward goes to the lungs to be transported to the muscles. Nasal depression The nose is the main outer part of the respiratory framework and the inner part is the nasal depression. Amid motivation air races through the nostrils and the hairs in the maritime cavity channels the dust and dust particles. The nasal hole has two mucous films which traps microscopic organisms and after that secretes antibacterial …show more content…

Gases exchange by diffusion across the respiratory membrane. Oxygen diffuses into the blood and carbon dioxide diffuses from the blood into the lungs. alveoli Diaphragm When breathing in, the diaphragm contracts causing the thoracic cavity volume to increase, which makes air rush into the lungs. When breathing out, the diaphragm relaxes decreasing the volume of the thoracic cavity pushing the air out. This is an important part of respiration during exercise (O2 touch) as more air is needed in the body and carbon dioxide needs to be breathed out. Intercostal muscles The intercostal muscles are found between the ribs; these muscles contract and extend helping with breathing in and out. These muscles are important for when playing sport (O2 touch) as breathing in and out is assential when trying to get more oxygen to supply the muscles and to breath Co2 out. The external intercostals increase the volume of the thoracic cavity drawing air into the lungs when breathing in as the ribs are pulled upwards and outwards. External intercostal muscles Rib external intercostal …show more content…

Function - transport Oxygen is breathed into the lungs and is diffused into the blood via the surface of the aveoli in the capillaries and combines with haemoglobin which are in the red blood cells, then forming oxyhaemoglobin. Depending on the concentration of the blood results in the amount of oxygen taken up by the blood to reach equilibrium. Carbon dioxide is carried to the veins via the cardiovascular system where it is diffused into the lungs and then breathed out as a waste product of aerobic processes. Haemoglobin is the component which carries oxygen in red blood cells. It is a protein which can combine with oxygen to form oxyhaemoglobin. Oxyhaemoglobin is formed when oxygen combines with haemoglobin. It is then carried in the blood to body tissues/muscles where the oxygen is released by tissue respiration. Mechanisms of breathing Mechanisms of breathing Tidal volume Inspiratory reserve volume Expiratory reserve volume Respiratory volumes This is the volume of air inhaled and exhaled per

Bronchioles constrict from the increased pressure in the lungs from exhalation. Inhalation is easier because it relieves the pressure.

The trading of gasses in the middle of air and blood happens cross the dividers of respiratory alveoli. Alveoli are microscopic flimsy walled air sacs that give a colossal surface zone to gas dispersion. The locale of the lungs where gas trade with the blood happens is known as the respiratory zone. The trachea, bronchi, and bronchioles that convey air to the respiratory zone include the leading zone. The thoracic cavity is constrained by the mid-section divider and diaphragm.

The next system I dissected was the respiratory system. My first task was to find the trachea as well as the esophagus. My goal was to compare the structure of each. I found the trachea to be wider, stronger, and it had a bumpy surface. The structure of the esophagus is small, but versatile which allows it to move easily.

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,

From these questions that were given out by Dr. Frander, many students should have a great understanding what to expect to the mid-term exam. Dr. Frander really encouraged us to study because most of these questions are difficult. For instance, she gave us an example in a patient who has COPD/ emphysema. What we have concluded from this question what they are looking for the emphysema patients don’t have a problem of taking air in rather they have a problem of taking the air out. The main problem of the emphysema, they have a lot of mucus, and the alveoli which where the gas exchange takes is impaired.

Physiological Processes Gas exchange occurs because of the body’s involuntary response to breathe in response to: exchange carbon dioxide and oxygen, deliver oxygen to tissues and to regulate acid-base concentrations in the bloodstream. The air travels into the nose, down the trachea, bronchi, bronchioles, alveolar sacs then to the pulmonary capillaries. Froom the pulmonary capillaries hemoglobin picks up the oxygen molecules and travels through the arteries in the body to deliver the oxygen while picking up carbon dioxide and delivering it to the lungs through the veins and the process repeats. Since my patient has asthma along with a smaller diameter for air to pass through it causes severe inability to oxygenate the body during an asthma

The pharynx is a muscular tube that extends supero-inferiorly from the base of the cranium to the level of the inferior surface of the body of the sixth cervical vertebra. The pharynx lies dorsal to the nasal cavity, the oral cavity and the larynx. The nasal portion of the nasopharynx has bony elements in its wall and thus it is rigid, whereas the pharyngeal portion is contractile as a result of the muscular nature of its wall.4 The relationship between craniofacial morphology and respiratory function has been studied extensively since the beginning of 20th century54. Some authors claim that patients with deficient respiratory functions present with lip incompetency, increased anterior face height, maxillary constriction, protruded maxillary

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).

At the dynamic exercise onset, oxygen consumption starts to increase, continues to rise through the initial time of sustained exercise, but then flattens as transport and uptake are increased adequately so that the consumption is matched to the demand (Laughlin S245). In the recovery stage, oxygen uptake will eventually surpass oxygen supply to a point at which oxygen consumption rate exceeds aerobic capacity resulting in oxygen

The walls of the alveoli actually share a membrane with the capillaries in which oxygen and carbon dioxide move freely between the respiratory system and the bloodstream. Oxygen molecules attach to red blood cells, which travel back to the heart. At the same time, the carbon dioxide molecules in the alveoli are blown out of the body with the next exhalation." (Dugdale, 2012) Ventilation is another fact because if this not happen our body will be full of carbon dioxide and the oxygen will be down. Many times when the people here ventilation they get confused and think that they are talking about respiration that is not correct, is correct say that ventilation is similar to breathing but no to respiration, they are different "Movements of the ribs, rib muscles and diaphragm allow air into and out of the lungs.

While the external features are only for the passage of air, its primary job is to breathe and smell. Human nose has the capacity to recognize up to 10,000 separate odors. Odor needs to be volatile which is capable of entering nose as a gaseous state. Inside the nose there are olfactory epithelium (mucous membranes) located on the roof and upper part of both walls of the nasal cavity. Epithelium has some 5 million olfactory neurons and their support
