Q

Function of the Circulatory System

A

The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

Q

Trachea

A

It is a long, U-shaped tube that connects your larynx (voice box) to your lungs. It’s main function is to carry air in and out of your lungs. Because it’s a stiff, flexible tube, it provides a reliable pathway for oxygen to enter your body.

Q

Bronchi

A

The bronchi are the large tubes that connect to your trachea (windpipe) and direct the air you breathe to your right and left lungs. They are in your chest. At the end of the bronchi, the bronchioles carry air to small sacs in your lungs called alveoli.

Q

Alveoli

A

The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out. They look a bit like a bunch of grapes at the end of the bronchial branches.

Q

Artery

A

Arteries, a critical part of your cardiovascular system, are blood vessels that distribute oxygen-rich blood to your entire body. These tube-like vessels and the muscles inside them ensure your organs and tissues have the oxygen and nutrients they need to function.

Q

Vein

A

Veins are blood vessels that carry oxygen-poor blood to your heart. They are part of your circulatory system. They work together with other blood vessels and your heart to keep your blood moving.

Q

Capillaries

A

They are delicate blood vessels that exist throughout your body. They transport blood, nutrients and oxygen to cells in your organs and body systems. Capillaries are the smallest blood vessels in your vascular system.

Q

Pulmonary Veins

A

Pulmonary veins are blood vessels that carry oxygen-rich blood from your lungs to your heart. They are a part of the body’s pulmonary circuits that is a system of blood vessels that moves blood between your heart and your lungs.

Q

What is the difference between veins and arteries?

A

Arteries carry blood away from the heart, and veins carry blood towards the heart. With the exception of pulmonary blood vessels, arteries carry oxygenated blood and veins carry deoxygenated blood. Arteries have thick walls with muscle tissue. Veins have thinner walls and use valves to keep your blood flowing.

Q

How does oxygen move through the respiratory system?

A

Air that is breathed in moves down the trachea, into the lungs, through the bronchi then bronchioles then into the alveoli (Air sacs)

Q

Describe the movement of oxygen and carbon dioxide to and away from cells

A

During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

Q

What is the pharynx

A

The pharynx (throat) is the passageway leading from the mouth and nose to the esophagus and larynx. The pharynx permits the passage of swallowed solids and liquids into the esophagus, or gullet, and conducts air to and from the trachea, or windpipe, during respiration.

Q

What is the larynx

A

Your larynx is a hollow tube that connects your throat (pharynx) to the rest of your respiratory system. It helps you swallow safely and contains the vocal cords, so it’s often called the voice box.

17
Q

What is the epiglottis

A

The flap that covers the trachea during swallowing so that food does not enter the lungs

17
Q

What is the nasal cavity

A

The nasal passages filter and warm the air, and make it moist before it goes into the lungs.

18
Q

What is arterioles

A

Small blood vessels that carry blood away from your heart, are connectors between your arteries and capillaries. They control your blood pressure and blood flow throughout your body

19
Q

What are venules

A

After blood passes through the capillaries, it enters the smallest veins, called venules. From the venules, it flows into progressively larger and larger veins until it reaches the heart.
