Needed: Nutrient to deliver food and waste
protein
The nutrient responsible for delivering food and waste throughout the body is called blood. Blood is a fluid connective tissue that travels through a complex network of blood vessels, known as the circulatory system, to transport oxygen, nutrients, hormones, and waste products to and from various tissues and organs in the body.
The circulatory system consists of the heart, blood vessels (arteries, veins, and capillaries), and blood itself. The heart acts as a pump, pushing the blood through a network of arteries, which carry oxygenated blood away from the heart, and veins, which carry deoxygenated blood back toward the heart. Capillaries are tiny blood vessels that connect the arteries and veins, allowing for the exchange of oxygen, nutrients, and waste products with the body's cells.
As blood circulates through the body, it delivers nutrients, such as glucose, amino acids, vitamins, and minerals, to the cells for energy production, growth, and repair. It also carries away metabolic waste products, such as carbon dioxide and urea, which are produced by cells as byproducts of their normal functions.
Therefore, blood serves as the nutrient that transports food (nutrients) to cells and waste products away from cells, helping to maintain the overall functioning and balance of the body.
The nutrient that delivers food and removes waste in living organisms is called blood. Blood is a vital fluid found in humans and many other animals and performs several crucial functions, including the transportation of nutrients, oxygen, and waste products.
To understand how blood delivers food and removes waste, it's important to know the components of blood. Blood consists of red blood cells, white blood cells, platelets, and plasma. Red blood cells carry oxygen from the lungs to the body's tissues and organs, while also transporting carbon dioxide, a waste product, back to the lungs for removal.
The plasma, which makes up the largest portion of blood, serves as a medium for transporting various nutrients, including glucose, amino acids, and fats, to different parts of the body. These nutrients are absorbed from the digestive system and transported via blood to be utilized by cells for energy, growth, and repair.
Additionally, blood plays a crucial role in removing waste products generated by cellular metabolism. The waste products, such as carbon dioxide, urea, and other metabolic byproducts, are transported in the bloodstream to the organs responsible for their elimination. For example, the liver filters out toxins and converts them into less harmful substances, while the kidneys filter the blood, removing waste products and excess water to produce urine.
In summary, blood acts as the nutrient delivery system by transporting vital substances such as oxygen, nutrients, and hormones to cells and tissues. Simultaneously, it carries waste products away from cells and organs to the organs responsible for their elimination.
