Respiratory physiology

indirect calorimetry (Westerterp, 2013). Oxygen consumed during postexercise recovery period and during exercise above resting level contribute to calorie expenditure. The physiology of upperbody exercise and lower body exercise has been thoroughly researched and reviewed in so many research…

Our body functions and consumes gas (O2) differently at rest and in motion. Energy requirement to maintain the body’s condition at rest is very different than the energy requirement during maximal exercise. At rest, the muscle intake of gas is very little, but during activity, oxygen consumption is multiples due to the intense oxygen demands of the muscles. Other parameters that are expected to change during exercise are metabolic rate, heart rate and blood pressure, stroke volume, cardiac…

Neurophysiology plays an important role in terms of physical strength and sporting performance. Fatigue among sportspersons is a major limiter of performance. Therefore, the mechanism and the nature of the exercise associated fatigue should be well understood. The paper will touch on the some theories that attempt to explain the nature of fatigue. Brief Background and Findings of Previous Literature Several physiologists have attempted to explain the complex associations between fatigue and…

What are the primary functions of the respiratory system? The human respiratory system is made up of several organs (nose, pharynx, larynx, trachea, bronchi, and lungs). They are responsible in receiving oxygen and expelling carbon dioxide. However, the exchange of gases takes place in the lungs making them an important organ of the breathing process. RBC’s gather oxygen from the lungs transferring it to other parts of the body. During this process the RBC’s gather carbon dioxide and transfers…

Introduction: The Litoria caerulea (Green tree frog) has a very unique respiratory system that is very different to the Homo sapiens (Humans). The respiratory system is made up of organs in your body to help you breath by delivering oxygen to the body and expelling carbon dioxide. The respiratory system consists of Lungs, Diaphragm, Bronchi and Trachea along with others. These organs have crucial roles in the process of respiration (the act of breathing) (Hillendale Health, Hes.ucfsd.org, 2014)…

Blood is the only liquid in the body that is classified as connective tissue. Its function is to transport oxygen, metabolic wastes such as carbon dioxide and nitrogenous waste from the kidneys. Regulation of the body’s pH, body temperature, and maintenance of the liquid volume in the circulatory system. Lastly, protection by way of Leukocyte activation and preventing blood loss by way of the platelets in the blood. Blood is composed of 55% plasma (water, salts, plasma proteins, and other…

The resonatory system includes the nasal cavity and soft palate and portions of the anatomically defined respiratory and digestive systems. (Seikel, King, & Drumright, 2010). One disorder that may affect a person’s ability to use the resonatory system to produce sufficient speech is velopharyngeal insufficiency, or VPI. This is a disorder which results in the improper closure of the velopharyngeal sphincter (soft palate muscle in the mouth) during speech, allowing air to escape through the nose…

The respiratory system is responsible for the balance of oxygen and carbon dioxide in the body to meet metabolic demands. The way a person’s breathe can be affected is by emotions and/or changes in the internal environment. The breathing process is mainly controlled by the brainstem and peripheral system. The brainstem controls several important functions of the body like arousal, breathing, and blood pressure, among other functions. In the brainstem, the medullary respiratory center consists of…

It test how well you inhale and exhale, and it also test how much air your lungs take in with each breath. To perform this test, an instrument called a spirometer is used which measures the volume of air moving in and out of the lungs during pulmonary ventilation. When given this test a person can be standing up or sitting down but whichever one that person must remain in that position throughout the whole test. The person cannot change positions because that will mess of the results from the…
