Which is not a part of the respiratory system?

Which is not a part of the respiratory system?

Any other organ except the wind pipe, larynx, pharynx, trachea, lungs, bronchi, bronchioles, and the alveoli are not part of the respiratory system.

What are the 4 parts of the respiratory system?

Respiratory system

• Nose.
• Mouth.
• Throat (pharynx)
• Voice box (larynx)
• Windpipe (trachea)
• Large airways (bronchi)
• Lungs.

Which of the following are part of the respiratory system?

What Are the Parts of the Respiratory System? The respiratory system includes the nose, mouth, throat, voice box, windpipe, and lungs. Air enters the respiratory system through the nose or the mouth.

What is the anatomy of the respiratory system?

ANATOMY OF RESPIRATORY SYSTEM Anatomically, respiratory tract is divided into upper (organ outside thorax – nose, pharynx and larynx) and lower respiratory tract (organ within thorax – trachea, bronchi, bronchioles, alveolar duct and alveoli).

What is the anatomy and physiology of the lungs?

Gross Anatomy of the Lungs The lungs are pyramid-shaped, paired organs that are connected to the trachea by the right and left bronchi; on the inferior surface, the lungs are bordered by the diaphragm. The diaphragm is the flat, dome-shaped muscle located at the base of the lungs and thoracic cavity.

What is the physiology of the lungs?

The lungs are the foundational organs of the respiratory system, whose most basic function is to facilitate gas exchange from the environment into the bloodstream. Oxygen gets transported through the alveoli into the capillary network, where it can enter the arterial system, ultimately to perfuse tissue.

What is the basic structure of the lungs?

The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic.

What are the different parts of the lungs?

Summary Each lung is divided into lobes. The bronchial tree running through your lungs is made up of the windpipe, bronchi, bronchioles, and alveoli.

Which organs are located in the thoracic cavity?

The vertebrate thorax contains the chief organs of respiration and circulation—namely, the lungs, some air passages, the heart, and the largest blood vessels (see thoracic cavity). Below, it is bounded by the diaphragm. The bony framework is encased with muscles, fat, and cutaneous tissues (skin).

Where is the heart located in the thoracic cavity?

The heart is located within the thoracic cavity, medially between the lungs in the mediastinum. It is about the size of a fist, is broad at the top, and tapers toward the base.

What are the three parts of the thoracic cavity?

The thoracic cavity is divided into three main regions: (1) the right pleural cavity, (2) the left pleural cavity (the pleural cavities contain the lungs), and (3) the mediastinum, a midline structure that separates the right and left pleural cavities.

What structures are located in the abdominal cavity?

The abdominal cavity contains the greater part of the digestive tract, the liver and pancreas, the spleen, the kidneys, and the adrenal glands located above the kidneys.
