Krisha A. Aguilar Prof. Ivan Marcelo Duka G-7L BIO 2 RESPIRATORY SYSTEM The Respiratory system consists of organs and tissues that aid the oxygen to travel in the body and emits the waste gases out of the body. It is also called as the oxygen delivery system for it is the system responsible in delivering the oxygen to all parts of the body. The process of breathing‚ the inhalation of oxygen and exhalation of carbon dioxide‚ is called respiration. Respiration can be described
Premium Respiratory system Oxygen
The respiratory system is composed of the nasal cavity‚ nostril‚ oral cavity‚ pharynx‚ larynx‚ trachea‚ carina of trachea‚ right main bronchus‚ right lung‚ left main bronchus‚ left lung‚ and diaphragm. These major organs collectively work together to give the body oxygen and eliminate carbon dioxide as we breathe. In order for the respiratory system to be fully capable of function‚ four procedures (pulmonary ventilation‚ external respiration‚ transport of respiratory gases‚ internal respiration)

The Respiratory System The human respiratory system plays a very important part in our bodies. Without it‚ we wouldn’t be alive! We need air to move through our bodies at all times. Breathing‚ is a key necessity for life. Our respiratory system is made up of many organs that all work together. The goal of breathing is to deliver oxygen to the body and take away carbon dioxide. The respiratory system organs all work together‚ like a engine in a car‚ they all have a important role. Some

Respiration. *The respiratory system consists of tubes that filter incoming air and transport it into the microscopic alveoli where gases are exchanged the entire process of exchanging gases between the atmosphere and body cells is called respiration and consists of the following: ventilation‚ gas exchange between blood and lungs‚ gas transport in the bloodstream‚ gas exchange between the blood and body cells‚ and cellular respiration *The organs of the respiratory tract can be divided into two

Exercise No. Respiratory System I. Introduction Oxygen is a very important element which our body needs. Without oxygen life is not possible without oxygen which helps in producing energies that our body cells need. But‚ how do we acquire this oxygen needed by the body? It is by the process called Respiration. Respiration is a process of taking in and out of air from the body. There are two kinds of respiration called cellular respiration and external respiration. Cellular respiration

Complete information on the mechanism of Respiratory System in Man NIRMALA AGARWAL Respiratory organs are those which are concerned with the passage of the air to and from the lungs. The latter are‚ of course‚ mot important of all. The passage is also called respiratory tract. For the sake of convenience‚ the respiratory tract can be divided into upper and lower parts. The upper part extends from the external nostrils (external openings of nose) to the vocal sac present in the neck. The lower part

1. Why do we need a cardiovascular system? Because we need to get oxygen through our system. 2. Make sure you know which circuits the left and right heart pump into (pulmonary or systemic). Also know the status of blood (fully oxygenated or not) at -the aorta: Left‚systematic‚ and fully oxygenated. -a pulmonary vein: Left side‚ pulmonary‚ and fully oxygenated. Goes from the right side of the body(heart) into the (left) pulmonary veins then goes to the left atrium then to the left ventricle then

Respiratory system Asthma A chronic (long term) lung disease that inflames and narrows the airways‚ asthma causes recurring periods of wheezing ( a sound when you breathe)‚ chest tightness‚ shortness of breath‚ and coughing. The coughing often occurs at night or early in the morning. Asthma is characterized by inflammation of the bronchial tubes with increased production of sticky secretions inside the tubes. People with asthma experience symptoms when that airways tighten‚ inflame or fill with mucus

Anatomy of the Respiratory System Nose and Nasal Cavity The nose and nasal cavity form the main external opening for the respiratory system and are the first section of the body’s airway—the respiratory tract through which air moves. The nose is a structure of the face made of cartilage‚ bone‚ muscle‚ and skin that supports and protects the anterior portion of the nasal cavity. The nasal cavity is a hollow space within the nose and skull that is lined with hairs and mucus membrane. The function
