3. TRANSPORTATION IN ANIMALS
Answers
Answer:
The transportation of animals is the intentional movement of animals by transport. Common categories of animals which are transported include livestock destined for sale or slaughter; zoological specimens; laboratory animals; race horses; pets; and wild animals being rescued or relocated. Methods of transporting animals vary greatly from species to species.
Explanation:
Plants and animals are the two major classifications of living things. All species under these two kingdoms require proper functioning of their body processes to survive. Among the most important of the body processes is the transport system, which enables all other body systems to function smoothly and -- by supplying sufficient nutrients -- allows members of the species to go about their normal activities .
Animals' Circulatory System
Animals are more complex creatures and require more food and nutrients because they are able to move about. Nutrients, together with oxygen and water, are necessary for proper survival of the organism. Once nutrients are broken down by the digestive system and are absorbed, they need to be distributed to various organs and tissues in the body to replace energy being expended. Oxygen is also needed by the animal body for various cellular processes and activities. An animal's circulatory system is the main transport system in the body and is one of the keys that make all other bodily functions possible.
Circulatory System Process
An animal's circulatory system consists of the heart, blood vessels -- arteries, veins and capillaries -- and the blood. The heart is the pump that pushes the blood to move along the arteries and veins. Blood from the heart and lungs usually passes through the arteries and carries with it oxygen and nutrients to be distributed into the many organs and cells via smaller blood vessels called the capillaries. After distribution of these nutrients, the blood goes into the veins and takes with it waste products, like carbon dioxide and other chemical wastes, to be eliminated via the organs responsible for proper waste excretion.
