Components of the Human Transport System:

The human transport system comprises of the following components:

1. Heart: The heart is a muscular organ that pumps blood throughout the body.

2. Blood vessels: Blood vessels are a network of tubes that carry blood throughout the body. There are three types of blood vessels: arteries, veins, and capillaries.

3. Blood: Blood is a fluid that carries oxygen, nutrients, and waste products throughout the body. It is composed of plasma, red blood cells, white blood cells, and platelets.

Functions of the Human Transport System:

1. Heart: The heart pumps blood throughout the body. It receives deoxygenated blood from the body and pumps it to the lungs, where it is oxygenated. The oxygenated blood is then pumped back to the heart and distributed to the rest of the body.

2. Blood vessels: Blood vessels transport blood throughout the body. Arteries carry oxygenated blood away from the heart to the rest of the body. Veins carry deoxygenated blood back to the heart. Capillaries are the smallest blood vessels and are responsible for exchanging nutrients, oxygen, and waste products between the blood and tissues.

3. Blood: Blood carries oxygen, nutrients, and waste products throughout the body. Plasma is the liquid component of blood that carries nutrients, hormones, and waste products. Red blood cells carry oxygen to the body's tissues. White blood cells help fight infection and disease. Platelets help the blood clot, which is important for stopping bleeding.

In summary, the human transport system is composed of the heart, blood vessels, and blood, which work together to transport oxygen, nutrients, and waste products throughout the body.
