REPSIRATORY DEPTH Depth- amplitude of each respiratory movement The depth of ventilation refers to the amount of air that is inhaled and exhaled. The amount of air inhaled and exhaled in one cycle is called the tidal volume. The more the chest cavity expands‚ the greater the depth of the ventilation. Full expansion of the chest wall with full relaxation on exhalation is a good indicator of adequate depth of breathing and adequate tidal volume. Many books will try and apply numbers in milliliters

Anatomy and Physiology of Respiratory System Overview Cells in the body require oxygen to survive. Vital functions of the body are carried out as the body is continuously supplied with oxygen. Without the respiratory system exchange of gases in the alveoli will not be made possible and systemic distribution of oxygen will not be made possible. Thetransportation of oxygen in the different parts of the body is accomplished by the blood of the cardiovascular system. However‚ it is the respiratory system
Free Respiratory system
ANATOMY AND PHYSIOLOGY OF THE RESPIRATORY SYSTEM The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe‚ we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system’s means of getting oxygen to the blood. Respiration is achieved through the mouth‚ nose‚ trachea‚ lungs‚ and diaphragm. Oxygen enters the

Comparative anatomy and physiology Horses Horses are obligate nasal breathers which means that they are different from many other mammals because they do not have the option of breathing through their mouths and must take in oxygen through their noses. Elephants The elephant is the only animal known to have no pleural space. Rather‚ the parietal and visceral pleura are both composed of dense connective tissue and joined to each other via loose connective tissue.[3] This lack of a pleural space

Latin systema respiratorium The respiratory system (or ventilatory system) is the biological system that introduces respiratory gases to the interior and performs gas exchange. In humans and other mammals‚ the anatomical features of the respiratory system include airways‚ lungs‚ and the respiratory
