what are the two functions of the respiratory system?

['Allows you to talk and to smell.', 'Brings air to body temperature and moisturizes it to the humidity level your body needs.', 'Delivers oxygen to the cells in your body.', 'Removes waste gases, including carbon dioxide, from the body when you exhale.']

The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

Gas exchange: The primary function of the lungs involving the transfer of oxygen from inhaled air into the blood and the transfer of carbon dioxide from the blood into the exhaled air.

['Regulates body temperature.', 'Moistens tissues in the eyes, nose and mouth.', 'Protects body organs and tissues.', 'Carries nutrients and oxygen to cells.', 'Lubricates joints.', 'Lessens burden the on kidneys and liver by flushing out waste products.']

The nose detects odor molecules and helps filter and warm the air we inhale. The upper respiratory system, or upper respiratory tract, consists of the nose and nasal cavity, the pharynx, and the larynx. These structures allow us to breathe and speak.

The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood. A reduced lung function means that the ability of lungs to exchange gases is reduced.

The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are the lungs, which carry out this exchange of gases as we breathe.

The respiratory tract performs the crucial function of gas exchange that is necessary for life. The immune system that operates within the respiratory tract must therefore be compatible with this vital function in maintaining open airways at all times.

The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.

The Role of the Respiratory System is to breathe in oxygen and breathe out carbon dioxide. This is known as respiration. The cells of the body use oxygen to perform functions that keep us alive. The waste product created by the cells once they have performed these functions is carbon dioxide.

The cardiovascular system has three main functions: transport of oxygen, carbon dioxide and nutrients. clotting of open wounds. regulation of body temperature.

['To pick up oxygen from the lungs and deliver it to tissues elsewhere.', 'To pick up carbon dioxide from other tissues and unload it in the lungs.']

Anatomy & Physiology of the Respiratory System Air is taken in via the upper airways (the nasal cavity, pharynx and larynx) through the lower airways (trachea, primary bronchi and bronchial tree) and into the small bronchioles and alveoli within the lung tissue.

The chest wall consists of the muscles of respiration—such as the diaphragm, the intercostal muscles, and the abdominal muscles—and the rib cage. The functions of the respiratory system include gas exchange, acid-base balance, phonation, pulmonary defense and metabolism, and the handling of bioactive materials.

Erythrocytes or Red Blood Cells (RBCs) have two principal functions. What are they? 1. To pick up oxygen from the lungs and deliver it to tissues elsewhere and 2. to pick carbon dioxide from tissues and unload it in the lungs.

Through breathing, inhalation and exhalation, the respiratory system facilitates the exchange of gases between the air and the blood and between the blood and the body's cells.
