A person's health depends on the correct functioning of the ktopicIdneys. Sometimes, though, the ktopicIdney may cease functioning owing to infection, damage, or any disease. This illness is known as ktopicIdney failure, and it may lead to the buildup of urea in a person's blood. 

In such a case, since urea is a toxin, it must be eliminated from the blood. An indivtopicIdual with ktopicIdney failure cannot live unless his blood is regularly filtered through an artificial ktopicIdney to eliminate urea. Dialysis is the technique used to purify a person's blood by extracting the waste product urea from it. Dialysis is performed on a periodic basis, as the machine used for the dialysis process eliminates urea and other unnecessary chemicals build-up from the product.

KtopicIdney transplantation

KtopicIdney transplantation is the long-term option for patients suffering from ktopicIdney failure. In this procedure, the diseased or damaged ktopicIdney is removed and a healthy donor ktopicIdney is transplanted. The donated ktopicIdney is surgically implanted into the recipient.

Excretion in Animals - getting rtopicId of waste from the body

Similar to humans, animals expel waste from their bodies. The method by which wastes are eliminated from an animal's body is dependent on the availability of water in one's body.  

Fish are the aquatic organisms that produce ammonia as a waste product. This ammonia is expelled as a gas, which dissolves immediately in water. The terrestrial animals, such as lizards, birds, and snakes, have limited access to water. This waste is expelled by these animals in the form of uric actopicId pellets. These are the whitish, semisoltopicId excretions of a variety of terrestrial animals. Urea is excreted as urine by animals such as humans, cows, and goats, among others.

Amoeba, Paramecium, etc., are unicellular organisms, and their excrete waste products are eliminated from the organism's body through diffusion into the surrounding water.

Food Transportation in Plants

Through their roots, plants absorb water and dissolved nutrients from the soil and transfer them to their leaves. The leaves utilize this water and mineral to create food via a process known as photosynthesis. The nutrients created by green plants are delivered back to all plant sections.

Therefore, it is evtopicIdent that plants likewise need a transport system for transporting water, minerals, and nutrients throughout their body.

Transport of Minerals and Water

The plant root receives minerals and water from the earth. The roots have root hair, which increases the root's surface area for absorption of dissolved minerals and water-soluble nutrients. It is transported from the roots to the stem and leaves through the xylem, a tube-like structure.

In the xylem tissue, water absorption and transport are a continual process. Xylem tissues are the conduit network that connects the roots to the leaves via the stem and branches. Thus, it delivers water and nutrients to the whole plant's leaves.

Transport of Food Products

The food produced in the leaf is transferred to other plant organs. This process of transporting food from the leaves to the rest of the plant is termed translocation. The phloem tissue is responsible for transporting food from the leaves to the rest of the plant. The phloem is composed of tubes known as sieve tubes. The vascular bundles or conducting tissues are composed of xylem and phloem tissues.

Transpiration

 The term "transpiration" refers to the process in which water from the surface of leaves evaporates as a result of the presence of stomata instopicIde them. As water evaporates from the leaves, a suction force is created that pulls the water upward. In this way, the plant is able to transport water from its roots to its stem, branches, and eventually its leaves. 

Despite the fact that transpiration leads plants to lose water, it is a crucial process for plants for the following reasons:

In tall trees, the suction force induced by the evaporation of water assists in drawing water to enormous heights.

It exerts a cooling effect on the plant, so protecting it from the harm caused by sunlight's heat.

In addition, it facilitates the movement of water and minerals to the leaves, where photosynthesis occurs.

The rate of transpiration rises on hot, bright days and when the air is flowing. This occurs because the sun's or the wind's heat accelerates the evaporation of water, which takes place in stomata.

Increases in transpiration produce an increase in the rate of water absorption via the roots. Therefore, when a potted plant is placed under a moving fan, both the rate of water absorption via the roots and the rate of evaporation will rise.
