What is the difference between tissues organs and cells

An organ is an incorporation of several types of tissue. There are five main organs in the animal body, which performs vital functions for the survival of an animal. They are brain, heart, lungs, liver, and kidney.

The brain is a component of the central nervous system of an animal, which coordinate body functions depending on the internal and external stimuli. Heart is the pump of the circulatory system of an animal, which transports both oxygen and nutrients to the cells in the body.

Lungs serve as an interface that allows the exchange of respiratory gases between the blood and external environment. Within the lungs, the blood is saturated with oxygen while carbon dioxide is removed from the blood.

Liver serves as the main storage organ in the animal body. It stores glucose as glycogen. Kidney is the main excretory organ in the body, allowing the removal of metabolic wastes and the excess fluid from the circulation. Organs in the animal body are organized into organ systems.

The primary organs in plants are stem, root, and leaves. Flowers, seeds, and spores are considered as reproductive organs in plants. The structures in a flower are shown in figure 2. Tissue: Tissue is any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products. Organ: An organ is a part of an organism, typically self-contained and has a specific vital function in the body.

Tissue: A tissue is composed of similar types of cells. Organ: An organ is composed of several types of tissues. Tissue: Tissue is involved in performing a single function in the body. Organ: An organ is capable of performing several functions in the body. It's a great example of layers of tissue working together to do several functions:. The organization of the anatomy starts with these three building blocks. Whether your talking about delicate tissue of the brain or the hardness of bone, it's still made of cells banded together into tissue and organized into organs.

At the organ level, complex functions become possible because of the specialized activities of various tissues.

Most organs contain more than one tissue type. For example, the stomach consists of smooth muscle tissue for churning movement while it is innervated, but it is also supplied by blood, which is a connective tissue.

The next level is the organ system level. Many organs working together to accomplish a common purpose create an organ system. For example, the heart and the blood vessels of the cardiovascular system circulate blood and transport oxygen and nutrients to all the body cells. Levels of Organization : Molecules form cells. Cells form tissues, and tissues form organs. Organs that fulfill related functions are called organ systems. An organism is made up of interconnected organ systems.
