Blood
What do red blood cells do?
They carry oxygen from the lungs to the body tissue.
What does the right side of your heart do?
The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide.
What do veins do?
They collect blood with low oxygen and send it back to the heart to be reoxygenated.
What creates blood pressure?
The force with which ventricles of the heart contract.
The circulatory system involves blood transporting critical items throughout the body. What are some of these items that blood needs to transport?
Hormones, nutrients, and gases.
What do white blood cells do?
They fight infections by attacking pathogens.
What does the left side of your heart do?
The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.
What do arteries do?
They send oxygenated blood from the heart to all of the organs in the body.
What would happen without blood pressure?
Blood would not be able to reach all parts of your body.
How do nutrients and oxygen move through your body?
They move through vessels.
What are platelets and plasma?
Platelets are small cell fragments that help in blood clotting by forming clots at the site of injury. Plasma is the liquid component of blood, primarily composed of water, proteins (like albumin), electrolytes, hormones, and nutrients, in which the other blood cells are suspended.
What parts of the right side of your heart pump oxygen-poor blood returning from the body back to the lungs to be reoxygenated?
On the right side of the heart, the right atrium and right ventricle work to pump oxygen-poor blood returning from the body back to the lungs to be reoxygenated.
What do capillaries do?
They exchange substances between the blood and body cells.
What is blood pressure primarily caused by?
It is primarily caused by the beating of your heart.
What is a waste product your body makes during circulation of oxygen and blood?
You body produces and gets rid of carbon dioxide.
Blood moving through the vessels allows for the exchange of what?
It allows for the exchange of gases and it brings nutrients to all the cells.
How does the heart move blood?
It is a muscle that contracts and relaxes constantly to pump and receive blood.
Oxygen and other materials move through what walls by diffusion?
How do your ventricle walls move to pump blood?
They move in a rhythmic pattern with your beating heart.
How does your body get rid of carbon dioxide?
It breathes in oxygen and breathes out carbon dioxide.
Where does blood move from and to?
It moves from the heart to the lungs, then back to the heart again before being transported out to the body.
What is a double loop system?
A double loop system is a type of circulatory system that includes two separate circuits for blood flow that cause blood to pass through the heart twice.
What is a major function of coronary arteries and coronary veins?
To give the heart its own blood supply, containing oxygen and glucose.
What do you feel when you check your pulse or heartbeat?
You feel the pumping action of your heart.
What specific vessel are substances exchanged in?
They are exchanged in capillaries.
