Roots Seeds Food molecules Hormones Carbon dioxide Oxygen This warrior needs to arrive to the human circulatory system, what are the ways he can take and why?
“ River of the life” transports everything within the body Blood is the only liquid tissue, it´s because of a protein- rich called plasma There are red blood cells: carry oxygen from the lungs to all cells of body, also carry carbon dioxide from cells back to the lungs to be exhaled, hemoglobin (blood color). There are white blood cells, they defend the body against bacteria, viruses or any foreign cells. And there are platelets, they help repair damaged blood vessels, for example when you cut your finger, it works, it creates a clot and stop the bleeding
The circulatory system carries blood and dissolved substances to and from different places in the body. The Heart has the job of pumping these things around the body. The Heart pumps blood and substances around the body in tubes called blood vessels. The Heart and blood vessels together make up the Circulatory System. What is the circulatory system?

This means it has two parts. Lungs Body cells the right side of the system deals with deoxygenated blood. the left side of the system deals with oxygenated blood.
The Heart These are arteries. They carry blood away from the heart. This is a vein. It brings blood from the body, except the lungs. Coronary arteries, the hearts own blood supply The heart has four chambers 2 atria 2 ventricles
blood from the heart gets around the body through blood vessels ARTERY Arteries carry blood away from the heart. VEIN Veins carry blood towards from the heart. CAPILLARY Capillaries link Arteries with Veins capillary bed A collection of capillaries is known as a capillary bed.
