Circulatory System Basics
System that transports nutrients and oxygen to cells.
A: What is the circulatory system?
Gas that is removed from the body by the circulatory system.
What is carbon dioxide?
Energy-related process creates heat in the body.
What is respiration?
Red blood cell part that carries oxygen.
What is haemoglobin?
Number of chambers in the human heart.
What is four?
Nutrients are absorbed in this system before being transported by the circulatory system.
What is the digestive system?
Carbon dioxide is removed from the body after being collected by the circulatory system via
What is exhaled via the lungs?
What the circulatory system does with the heat from respiration.
What is distribute it around the body?
The part of blood that helps to fight infection.
What are white blood cells?
The name of the blood vessels that carry blood away from the heart.
What are arteries?
System that supplies the oxygen that the circulatory system carries to the cells.
What is the respiratory system?
Besides carbon dioxide, this is removed from the cells via the circulatory system.
What are other waste products?
A chemical reaction caused by cells releasing energy.
What is respiration?
The part of blood that helps it to clot when you get a cut.
What are platelets?
The name of the blood vessels that carry blood to the heart.
What are veins?
This component of blood is mostly made of water and transports nutrients, hormones and waste.
What is plasma?

What are capillaries?
This type of circulation that moves blood between the heart and lungs.
What is pulmonary circulation?
Here is where most blood cells produced in the body.
What is the bone marrow?
During this phase the heart pushes blood from the atria into the ventricles
What is when the atria contract?
The function of red blood cells besides carrying oxygen
What is removing carbon dioxide from cells and transporting it to the lungs?
Veins have valves, but arteries do not because...
What is because veins have lower pressure and need valves to prevent backflow?
This type of circulation moves blood between the heart and the rest of the body.
What is systemic circulation?
This is the shape of a mature red blood cell and why is it important.
What is biconcave, to increase surface area for oxygen exchange?
This happens to the heart between contractions.
What is it relaxes and fills with blood?
