what is transportation in life process
Answers
Answer:
Transportation is a life process where substances synthesized or absorbed in one part of the body are carried to other parts of the body . ... It also transports waste material which is to be excreted out from the body.
Circulatory System and its Components
In human beings, the various organs associated with this system include the heart, lungs, blood vessels, capillaries, and blood. The heart is the pumping organ that squirts out blood. The heart does this with so much pressure that it is capable of squirting blood up to 9 meters high. It never stops and beats continuously so that blood can travel to all parts of the body.
Your blood travels through these blood vessels transporting oxygen, carbon dioxide, digested food, hormones and even waste products. It is amazing to see how transportation in human beings is carried out by the circulatory system, with the heart and the vast network of blood vessels.
Blood
Blood is an important fluid connective tissue. It is mainly composed of plasma and blood cells. There are three types of blood cells, namely, red blood cells, white blood cells, and blood platelets. The RBCs have haemoglobin, an iron-containing complex protein. The WBCs are the cells that help in fighting diseases and attack any foreign bodies in the blood. The blood platelets are the ones that help in clotting of blood.
Blood Vessels
In human beings, there is a phenomenon called double circulation that occurs, which is an efficient way. The heart pumps the blood, and through the various blood vessels, it travels to different organs and then comes back again to the heart. Now, this flow of blood in humans occurs in two pathways called the pulmonary pathway and the systemic pathway.
This system ensures that the deoxygenated blood (blood carrying carbon dioxide) from the right side of the heart goes to the lungs, where gaseous exchange occurs. Blood gets filled with oxygen from the lungs and carbon dioxide is given out to the lungs(from where it leaves the body). The oxygenated blood then travels from the left side of the heart to all other parts of the body.
The double circulation seen here ensures that there is no mixing of oxygenated blood and deoxygenated blood. There is also an efficient supply of oxygen to the body cells and a greater rate of blood flow in the body.
Heart
Heart and Blood Vessels
How do the oxygenated blood and the deoxygenated blood not get mixed? Firstly, they travel in different blood vessels. Secondly, in the heart, there are four chambers. The blood without oxygen and the blood with oxygen flow into different chambers.
The human heart is a muscular organ, which has four chambers. The two upper chambers called the right atrium and the left atrium, and the two lower chambers called the right ventricle and left ventricle. The right atrium and the right ventricle together may be called the right heart. The left atrium with the left ventricle together can be called as the left heart. All the chambers of the heart are separated by muscular walls called septum.
Blood Vessels
Arteries and veins are the main blood vessels. These are interconnected by a network of smaller vessels called capillaries. Veins carry deoxygenated blood to the right side of the heart whereas arteries carry oxygenated blood away from the heart to different parts of the body.
Lymphatic system
In human beings and vertebrates, the lymphatic system acts as a subsystem of the circulatory system. It also has a role to play in the transportation in human beings. Lymph is a special fluid called the tissue fluid. It plays a role in the exchange process of nutrients and gases that occurs through blood. Any excess fluid remaining in the cells and tissues is collected by the lymph and is drained into the veins, which carry blood.
Plants
The plant body is generally divided into roots, stem, and leaves. The roots are in the soil, which is the major source of nutrients in plants. Water and other nutrients enter the plant through the roots. The leaves are the food production centres. Using the sunlight and Carbon dioxide they synthesize food through photosynthesis in the chloroplasts.
Answer:
Transportation can be defined as the movement of any substance from one place to another. Water and nutrients required for all metabolic activities should be transported in the body of plants and animals. The waste material or excretory products should also move to the region of excretion.
