Transportation in human beings is a complex process that involves the movement of various substances throughout the body. This process is facilitated by the circulatory system, which comprises the heart, blood vessels, and blood.

Circulatory System

The circulatory system is responsible for the transportation of oxygen, nutrients, hormones, and other substances to different parts of the body. It is composed of three main components:

- The heart: This is a muscular organ that pumps blood throughout the body.
- Blood vessels: These are tubes that carry blood to and from the heart.
- Blood: This is a fluid that carries oxygen, nutrients, and other substances to different parts of the body.

Blood

Blood is composed of plasma, red blood cells, white blood cells, and platelets. Plasma is a yellowish fluid that carries nutrients, hormones, and waste products. Red blood cells contain hemoglobin, a protein that carries oxygen. White blood cells are responsible for fighting infections. Platelets are involved in blood clotting.

Transportation of Oxygen and Nutrients

The transportation of oxygen and nutrients is facilitated by the red blood cells. Oxygen is transported from the lungs to the cells of the body by the red blood cells. Nutrients such as glucose, amino acids, and fatty acids are also transported throughout the body by the blood.

Transportation of Waste Products

The circulatory system is also responsible for the removal of waste products from the body. Carbon dioxide, a waste product of cellular respiration, is transported from the cells to the lungs for elimination. Other waste products such as urea and uric acid are transported from the cells to the kidneys for elimination.

Conclusion

In conclusion, transportation in human beings is a complex process that involves the circulatory system. The heart, blood vessels, and blood work together to transport oxygen, nutrients, hormones, and waste products throughout the body. It is essential for maintaining a healthy body and ensuring proper functioning of all organs.

The main component of the transport system in human being are the Heart,blood and blood vessel.*Heart pump oxygenated blood throughout the body.It recieives deoxgenated blood from the various body parts and send this impure blood to the lungs for oxygenation.*Blood help in the transport of oxygen , nutrition , carbon dioxide and nitrogenous waste.*The blood vessel (arteries,vein and capillaries)carry blood either away from heart to various organ or from various organ back of the heart.
