gas exchange

the lungs are able to expand to breathe in more air but able to condense to let the carbon dioxide out.
difference between oxygenated blood and deoxygenated blood is that oxygenated blood is composed of more oxygen whereas deoxygenated blood is composed of less oxygen. The oxygenated blood goes into the heart by the left atrium while the deoxygenated blood enters through the right atrium.
Circulatory system
Blood contains plasma,red blood cells, white blood cells and platelets

Plasma-Transporting dissolved carbon dioxide, digested food molecules, urea and hormones
valves-valves stop backwards blood flow as they work in pairs to keep the blood flowing forward. When one valves opens the other one shuts so the blood doesn't go backwards
Veins- carries blood towards the heart(thinner walls)
arteries- carries blood away from the heart.(thick muscular walls)
Capillaries-Allows diffusion of gases and nutrients from blood into the body cells(one cell thick walls)
Gas exchange and circulatory system work together as the alveoli transfers the oxygen into to blood stream as they have one cell walls making itquick and easy. The blood gives the alveoli the waste called carbon dioxide to breathe out.
vaccinations

They insert the weakened or dead disease into your body so that the lymphocyte can create matching antibodies to the diseases antigens.
Therefore if the disease comes back the lymphocyte already has matching memory cells meaning that they can kill the disease quickly.
