What is the name of the tube that carries gases in and out of the lungs?
Bronchial tree The trachea is a tube that carries the air in and out of your lungs. Each lung has a tube called a bronchus that connects to the trachea. The trachea and bronchi airways form an upside-down “Y” in your chest.
What tube allows air in and out of the body?
Your trachea is divided into 2 air passages called bronchial tubes. One bronchial tube leads to the left lung, the other to the right lung. For the lungs to perform their best, the airways need to be open during inhalation and exhalation and need to be free from inflammation (swelling) and abnormal amounts of mucus.
What is the name of the process by which gases move in and out of the blood?
Every few seconds, with each inhalation, air fills a large portion of the millions of alveoli. In a process called diffusion, oxygen moves from the alveoli to the blood through the capillaries (tiny blood vessels) lining the alveolar walls.
What is hairlike tube?
The trachea splits into 2 bronchial tubes in your lungs. These are called the left bronchus and right bronchus. The bronchus tubes keep branching off into smaller and smaller tubes called bronchi. The tubes are lined with fine hair-like structures called cilia.
Where does exchange of gases between blood and tissue occur?
Exchange of Gases, Nutrients, and Waste Between Blood and Tissue Occurs in the Capillaries. Capillaries are tiny vessels that branch out from arterioles to form networks around body cells. In the lungs, capillaries absorb oxygen from inhaled air into the bloodstream and release carbon dioxide for exhalation.
Which is the blood vessel that carries oxygen?
A blood vessel is a tube that carries blood. Oxygen rich blood leaves the left side of the heart and enters the aorta. The aorta branches into arteries, which eventually branch into smaller arterioles. Arterioles carry blood and oxygen into the smallest blood vessels, the capillaries.
How are blood vessels transported throughout the body?
Blood vessels flow blood throughout the body. Arteries transport blood away from the heart. Veins return blood back toward the heart. Capillaries surround body cells and tissues to deliver and absorb oxygen, nutrients, and other substances. The capillaries also connect the branches of arteries and to the branches of veins.
What are the smallest tubes in the vascular system?
The arteries branch off into smaller and smaller tubes. These bring oxygen and other nutrients to the cells of the body’s tissues and organs. The smallest tubes are called capillaries. As blood moves through the capillaries, the oxygen and other nutrients move out into the cells.
