M.A. Lung/PHYO2202/Respiration/13-14 VENTILATION ． Pulmonary Ventilation (V) It is the amount of air moved into or out of the lungs per minute; normal value is about 6 L/min. ． V = f x TV where f‚ frequency of breathing (breaths/min) TV‚ tidal volume (L) ． Alveolar Ventilation (VA) It is the amount of air reaching the functioning alveoli (exchange surface) per minute; normal value is about 4.2 L/min. ． VA = f x VA or f x (TV - VD) where VA‚ volume of air reaching the functioning

Exercise Physiology Responses To Steady-State Exercise Once an athlete has been performing continuous exercise for a period of around 20 minutes‚ their body reaches a steady-state. Continuous exercise includes all forms of exercise that have no stopping periods such as jogging‚ swimming or cycling. Examples of non-continuous exercise would be weight lifting‚ interval training and boxing. Steady state is when the body is working at a steady state it means that lactic acid removal is occurring

1/ What is the driving force in the diffusion? Randomness. As far as forces go i believe you can end up with a pressure if you have two different concentration on opposite sides of a membrane. Cells have been know to explode as a result of this effect.

INTRODUCTION Give a brief description in your own words of the objectives and aims of this practical. The aim of this practical was to understand how the autonomic nervous system has an effect In the ileum. Through this‚ we can delve deeper by understanding how nerves‚ through the actions Of various neurotransmitters affect the motility of the gastrointesital tract. Furthermore‚ we can investigate The effects of drugs‚ and their uses in replicating effects of autonomic neurotransmitters

There are three types of muscle skeletal which are voluntary‚ smooth muscle which are involuntary and cardiac muscle. Muscle is made up of protein filaments‚ myosin and actin. These filaments slide past each other to produce a contraction which changes both the length and shape of the cell. The primary function of the muscle is to produce both movement and force. Skeletal muscle is composed of bundles of muscle fibres containing myofibrils of thick and thin filaments (myosin and actin). Skeletal

Introduction:Spirometry is the classic pulmonary function test‚ which measures the volume of air inspired or expired as a function of time. It can monitor quiet breathing and thereby measure tidal volume‚ and also trace deep inspirations and expirations to give information about vital capacity. Spirometrymay also be used to measure forced expiration rates and volumes and to compute FEV1/FVC ratios. Spirometry provides an objective measurement of lung function. It will measure the Expiratory Vital

Christopher Couchell Muscle Physiology Purpose: The Purpose of this exercise is to understand how muscle twitch‚ contract and react to different activities. Exercise 1: Muscle Twitch A. What is a muscle twitch? A muscle twitch is the fasciculation ‚ or "muscle twitch"‚ is a small‚ local‚ involuntary muscle contraction and relaxation visible under the skin. B. According to the graphs‚ which muscle has the fastest twitch? Why? The lateral rectus eye muscle has the fastest twitch.
