Respiratory physiology

Experiment 14.1 The Histology of the Lung Introduction: This experiment will give you a change to see an alveolus, a capillary, and the respiratory membrane. Procedure: I studied a slide of a lung tissue and observed the various structures, mainly the alveoli, capillaries, and the respiratory membrane. I then drew pictures of the structures in different microscope powers. Summary: Very briefly, we will discuss how air travels to the lungs. First, air travels down your larynx, and then into…

ASTHMA Asthma is a condition that influences a relaxing. Inside the lungs is soaring direction Star called breathing tubes or bronchial tubes. With asthma, a portion of the little road that can fabulous and limited, making it harder for air to get past. We should discuss relaxing. When you take in, air enters your nose or mouth, then goes into the windpipe, likewise called the trachea from that point, the air goes into the lungs through the breathing tubes. These flying leads gaps like…

nutrition, mobility, and fatigue. Acid-Base Balance is affected in a variety of different ways by gas exchange. For example, with chronic respiratory conditions such as COPD it causes respiratory acidosis which is essentially an increase in carbonic acid and a decrease in pH. Then the opposite would be when you breathe off too much carbon dioxide, this causes respiratory alkalosis because it is a decrease in carbonic acid and an increases in pH. The next interrelated concept is perfusion;…

Coughing is one of the most common health problems. When there is a blockage or irritant in your throat or upper air passages, your brain thinks a foreign element is present and tells your body to cough to remove that element. dry cough diagram Coughing can also be due to a viral infection, common cold, flu, and smoking or health problems such as asthma, tuberculosis, and lung cancer. Some of the symptoms of a cough are itchy throat, chest pain, and congestion. Instead of using…

The Pleural Cavity is a very important cavity in the body, simply because it consists of how a person breathes. It includes an intrapulmonary pressure, atmospheric pressure and airflow within the lungs. “Intrapulmonary pressure is the pressure within the lungs, atmospheric pressure is the pressure used in all directions at any given point by the weight of the atmosphere and air flow is simply the motion of air. Intrapulmonary pressure and atmospheric pressure are usually measured in units of…

Asthma is a disease that affects your lungs. Your air passages inflame and it causes a temporary narrowing of the airways that carry oxygen to your lungs. An asthma attack is a sudden worsening of asthma symptoms caused by the tightening of muscles around your airways. During the asthma attack, the lining of the airways also becomes swollen or inflamed and thicker mucus is produced. It can be triggered by allergens, exercise, smoke, pollution, or airway infections. If your asthma is severe it…

The process of oxygen and carbon dioxide moving in opposite directions across respiratory membranes is referred to as gas exchange. To extract energy from the sugars and acids in our body, oxygen is needed. During the process of extracting energy carbon dioxide is produced and the body must rid its self of this toxin. Movement of the cellular molecules in the human body in a manner that is not directional is called diffusion. Net diffusion occurs when there is a directed movement and…

Chronic inflammation in the airways limits the amount of airflow to the lungs. It is progressive and relates to abnormal inflammatory response in the lungs that affects gas exchange. “This is caused by loss of elastic recoil and airflow obstruction caused by mucosal hypersecretion, mucosal edema, and bronchospasm”. One of the two Chronic Obstructive Pulmonary Disease (COPD) is chronic bronchitis. It is caused when the bronchi and bronchioles become inflamed by exposure to smoke or environmental…

Respiratory systems vary from species to species but the basic anatomy for Serpentes suborder is straightforward. The average Serpentes respiratory system has two external nares, two internal nares, and a nasal cavity. While Serpentes have a nose, their nose is only meant to be another pathway for respiration. They are not used to smell like a human nose is used for. Serpentes have a glottis that is a vertical slit because it is always closed. The glottis is situated right behind the tongue and…

Breathe in People breathe deeply to live others hold in to live longer. Breathe in, and out, feels normal right? Well, what’s not normal is what you may have taken in. It is well known that we all need air to keep the machine that we call our body alive. Cleaner air is essential to maintaining a healthy life, and you may not know that until you take in the problem through nose and mouth. This problem has begun to take its toll on many of our elderly, people with asthma and children; often…
