Assessing Blood Pressure Anatomy of the Heart The heart is located in the thoracic cavity between the lungs within the mediastinum. It is a hollow‚ cone-shaped‚ muscular organ about the size of a fist. Functions of the Heart keeps O2-poor blood separate from O2-rich blood; keeps the blood flowing in one direction—blood flows away from and then back to the heart in each circuit; creates blood pressure‚ which moves the blood through the circuits; Regulates the blood supply based on

constancy of alveolar gas tensions. Firstly it is important to understand what the anatomical dead space and FRC actually are. The anatomical dead space refers to the gas in the conducting areas of the respiratory system where air does not come into contact with alveoli. Examples of places in the respiratory system where anatomical dead space is present are the mouth and trachea. The functional residual capacity is the amount of air that remains in the lungs after a normal and passive expiration. It is usually

Inspiration/ inhalation is the first half of the respiratory cycle where breath is drawn. Several muscles in the respiratory system contribute to the process of inhalation. However‚ the diaphragm and the external and internal intercostals are the primary muscles of inhalation. The diaphragm originates at ribs 7 through 12‚ the xiphoid process‚ and the first 3 lumbar vertebrae. The diaphragm inserts on its’ central tendon which it pulls down and forwards through contraction in order to increase the

Energy and Metabolism P4:.2. Explain the role of the respiratory system in energy metabolism by referring to- a) Inhalation and exhalation. b) Gaseous exchange between alveoli and blood. The respiratory system takes oxygen (O2) into the body and eliminates carbon dioxide (CO2). It also enables speech production. Our bodies need energy for movement‚ growth and reproduction. This energy can only be obtained from the food we eat. By the process of respiration‚ chemicals of food are eliminated

A. I am going to talk about bronchitis. This condition is related to chapter 23‚ the respiratory system. B. Bronchitis is an illness related to the respiratory system in which our ability to breath gets affected because of an inflammation of the mucous membrane in the bronchial tubes. Two different stages of the disease can be presented; the acute‚ which is a short-term chest cold‚ or the chronic‚ in which the inflammation persist and remains as a daily chough becoming a more serious condition that

It includes the nasal passages or nostrils‚ the pharynx‚ the larynx‚ the bronchi and the lungs. The respiratory system starts with the nose that encloses the nasal cavity. The nasal cavity opens outside through the openings called the nostrils. The nasal
