What is a group of similar tissues that work together?

Índice Show

A group of tissues performing a particular function in the body forms a/an(a) Cell(b) Tissue(c) Organ(d) Organ system
The correct option is A Organ systemLiving organisms can be unicellular or multicellular based on the number of cells in an organism. In muticellular organisms, several cells come together to form tissues. For example, epithelial tissue, connective tissue, etc. Tissues come together to form organs. For example, lungs, trachea, etc. Several organs in the body come together to perform a common body function and it is known as organ system. For example lungs, bronchi, pharynx, trachea, etc. come together to form the respiratory system in human body. All these organs facilitate and perform the common function of exchange of gases.
The correct option is AtissueTissues are groups of cells that have a similar structure and act together to perform a specific function. Different tissues make up organs. Different organs work together to form an organ system.

Answer

Verified

Hint: Tissues are a group of similar cells that have a common function which further associate to form a more complex structure.

Complete answer:
The Group of tissues performing particular functions in the body is called an organ or an organ is a structure composed of at least two or more tissue types. Each tissue performs a specific function of the body. Several organs together constitute an organ system.

Additional information:
1. Cells are the basic unit of life. A group of cells having the same structure and performing the same function forms a tissue.
2. All tissues consist of cells and extracellular materials.
3. Cells of the specific categories have similar functions, although some cells of nervous tissues and epithelium overlap.
4. Organs are of two types: parenchyma (tissue which forms various organs) and stroma (tissues having various functions including support, connection, and structure)
5. A group of organs that work together to maintain a stable internal environment and perform a particular function is called an organ system.
6. In humans and other multicellular animals, cells are made up of four basic tissue types – epithelial cells, connective tissue, muscle tissue, and nervous tissue.
7. The whole body constitutes muscles whereas the heart also is made up of specialized muscle cells. The outer layer of the skin is called epithelial tissue.

So, the correct answer is ‘Organ’.

Note: The English word “organ “ dates back to the twelfth century about any musical instrument. At the same time, a second meaning arose, about a “body part adapted to a certain function “. Human anatomy was first studied and discovered by Andreas Vesalius, he studied various organs of the human body. Recently, a new organ called mysentry was discovered by scientists which results in a total of 79 body organs.

The human body is organized at several levels of scale that can each be examined.

Learning Objectives

Characterize where tissues fall in levels of organization

Key Points

The human body has many levels of structural organization: atoms, cells, tissues, organs, and organ system.
The simplest level is the chemical level, which includes tiny building blocks such as atoms.
Cells are the smallest functional units of life.
Tissues are groups of similar cells that have a common function.
An organ is a structure that is composed of at least two or more tissue types and performs a specific set of functions for the body.
Many organs working together to accomplish a common purpose is called an organ system.

Tissues in the Human Body

The human body has many levels of structural organization. The simplest level is the chemical level, which includes tiny building blocks such as atoms. Cells are the smallest functional units of life. The simplest living creatures are single cell creatures, but in complex life forms, such as human beings, cells also exist in the tissue level.

Tissues are groups of similar cells that have a common function. The four basic tissue types are epithelial, muscle, connective, and nervous tissue. Each tissue type has a characteristic role in the body:

Epithelium covers the body surface and lines body cavities.
Muscle provides movement.
Connective tissue supports and protects body organs.
Nervous tissue provides a means of rapid internal communication by transmitting electrical impulses.

Organs: Made of Tissues

An organ is a structure that is composed of at least two or more tissue types and performs a specific set of functions for the body. The liver, stomach, brain, and blood are all different organs and perform different functions. Each organ is a specialized functional center responsible for a specific function of the body.

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.
