Answers
jjjjjjjjjjjjjjjjjjf09urfnciedh1) In Autotrophic mode of nutrition, food is prepared from inorganic raw material whereas in Heterotrophic mode of nutrition the food is taken from the autotrophs and is then broken down in simpler form.
2) Breathing is a physical process where oxygen is inhaled and carbon dioxide is exhaled whereas Respiration is a chemical process in which glucose is broken down into simpler form in the presence of oxygen.
3) Arteries and Veins both have same function of carrying blood but the main difference is that Arteries carry oxygenated blood from heart to other parts of the body whereas veins carry de-oxygenated blood from other parts of the body to the heart.
4) Blood contains RBC's, WBC's, platelets and other components whereas Lymph is mainly composed of White Blood cells and Blood flows through the circulatory system whereas Lymph flows through the Lymphatic system.
5) Auricular systole occurs when Atria contracts to force the blood into Ventricles whereas Ventricular systole is the contraction of ventricles which forces the blood into Aorta and Pulmonary artery.
