The Circulatory System
The circulatory system is made up of Blood, Blood Vessels and the Heart
The Blood vessels are the veins, arteries and capillaries.
- Capillaries are one cell thick and allow diffusion to happen between oxygen and carbon dioxide at the lungs.
- Arteries carry oxygenated blood away from the heart to the body. They have thick walls in order to carry high volumes of blood to vital organs and muscles.
- Veins carry deoxygenated blood from the body to the heart veins are thin and have backflow valves to stop blood going backwards and potentially ending in a clot.
Blood is made up of Red Blood Cells, White Blood Cells, Platelets and Plasma.
- Red Blood Cells carry oxygen and are dome shaped.
- White Blood Cells fight infections and kill pathogens.
- Platelets help blood clot and stop infections entering in to open wounds
- Plasma is a fluid that helps the blood flow.
