Human respiratory system , the system in humans that takes up oxygen and expels carbon dioxide. The human gas-exchanging organ, the lung , is located in the thorax, where its delicate tissues are protected by the bony and muscular thoracic cage.

5.01 Respiratory System Function

The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide. The respiratory system has many functions. Besides helping you inhale breathe in and exhale breathe out , it:.

Respiratory system (pulmonary system) anatomy

Place your hand over your chest, take a deep breath, and then let it out. Of course you already know that your lungs fill with air when you breathe, but did you know that your respiratory system does more than simply move oxygen into and out of your lungs? The structures of the respiratory system interact with structures of the skeletal, circulatory, and muscular systems to help you smell, speak, and move oxygen into your bloodstream and waste out of it.

If you look in the image below, you'll see a treelike structure in each lung.

Anatomy and Physiology: The Relationships of the Respiratory System

The respiratory system also helps us to smell and create sound. The following are the five key functions of the respiratory system. The respiratory system aids in breathing, also called pulmonary ventilation. In pulmonary ventilation, air is inhaled through the nasal and oral cavities the nose and mouth. It moves through the pharynx, larynx, and trachea into the lungs.

The lungs are the primary organs of the respiratory system in humans and many other animals including a few fish and some snails. In mammals and most other vertebrates , two lungs are located near the backbone on either side of the heart. Their function in the respiratory system is to extract oxygen from the atmosphere and transfer it into the bloodstream , and to release carbon dioxide from the bloodstream into the atmosphere, in a process of gas exchange. Respiration is driven by different muscular systems in different species. Mammals, reptiles and birds use their different muscles to support and foster breathing.

What is respiration?

The respiratory system also respiratory apparatus , ventilatory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history. In land animals the respiratory surface is internalized as linings of the lungs. These microscopic air sacs have a very rich blood supply, thus bringing the air into close contact with the blood. These enter the lungs where they branch into progressively narrower secondary and tertiary bronchi that branch into numerous smaller tubes, the bronchioles. In birds the bronchioles are termed parabronchi.

Human respiratory system , the system in humans that takes up oxygen and expels carbon dioxide. The human gas-exchanging organ, the lung , is located in the thorax, where its delicate tissues are protected by the bony and muscular thoracic cage. The lung provides the tissues of the human body with a continuous flow of oxygen and clears the blood of the gaseous waste product, carbon dioxide. Atmospheric air is pumped in and out regularly through a system of pipes, called conducting airways, which join the gas-exchange region with the outside of the body. The airways can be divided into upper and lower airway systems. The transition between the two systems is located where the pathways of the respiratory and digestive systems cross, just at the top of the larynx. The upper airway system comprises the nose and the paranasal cavities or sinuses , the pharynx or throat , and partly also the oral cavity , since it may be used for breathing.

Он стал ждать, когда его компьютер разогреется, и Сьюзан занервничала. Что, если Хейл захочет взглянуть на включенный монитор ТРАНСТЕКСТА. Вообще-то ему это ни к чему, но Сьюзан знала, что его не удовлетворит скороспелая ложь о диагностической программе, над которой машина бьется уже шестнадцать часов.

Сьюзан на секунду задумалась. - ARA обслуживает в основном американских клиентов. Вы полагаете, что Северная Дакота может быть где-то. - Возможно.  - Стратмор пожал плечами.

Если Меган продала кольцо и улетела, нет никакой возможности узнать, где оно. Беккер закрыл глаза и попытался сосредоточиться. Итак, каков следующий шаг. Он решил подумать об этом через минуту. Сейчас ему надо было совершить давно уже откладываемую прогулку в туалетную комнату.

Смит поднял брови. - Выходит, выбор оружия был идеальным. Сьюзан смотрела, как Танкадо повалился на бок и, наконец, на спину.
