The components of Human Transport System comprises the heart, blood, Blood Vessels, and the lymphatic system. The Heart circulates blood throughout the body.The blood carries oxygen, carbon dioxide, nutrients, hormones and wastes. Blood Vessels are the network of tubes that carry blood.Arteries carry oxygenated blood, capillaries that facilitate material exchange and Veins return deoxygenated blood to the Heart. The lymphatic system transports lymphocytes and defends the body against pathogens, absorbs lipids and eliminates waste.

Saliva plays a crucial role in the digestion of food by lubricating and binding food, breaking down complex carbohydrates, maintaining oral hygiene and preventing the growth of bacteria. Saliva also contains enzymes that help initiate the digestive process by breaking down starch into simpler sugars. Saliva is an important part of the digestive process, facilitating the breakdown and absorption of nutrients from food.

Digestive enzymes, such as salivary amylase and lipase, play an important role in the breakdown of carbohydrates, proteins, fats and nucleic acids. They are secreted at various points in the digestive system, including the mouth, stomach and small intestine. These enzymes facilitate the digestion of complex food molecules into simpler forms that can be absorbed by the body. Without digestive enzymes, nutrient absorption would be compromised
