Answer:
4 functions of blood are:
1) the blood carries digested food with it to all parts of the body
2) It has haemoglobin which insures that blood is of red colour
3) It has also white blood cells which fight against various infections and diseases
4) it has platelets which ensure blood clotting
the blood looks red due to the presence of RBC in it. the RBC have hemoglobin which make sure that the blood is of red colour only.
the left atrium transfers oxygenated blood from lungs to heart. the left ventricle further transports this blood to the the rest of the body
