what is the relationship between cells tissues and organs and organ systems?

The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs.

Organs are the body's recognizable structures (for example, the heart, lungs, liver, eyes, and stomach) that perform specific functions. An organ is made of several types of tissue and therefore several types of cells.

The main difference between organ and organelle is that organ is a large part of an organism, composed of tissues which perform similar functions whereas organelle is a specialized structure found inside cells, which carries out a specific life process. Organelles form cells.

The human heart is an organ that pumps blood throughout the body via the circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes. "The tissues of the body need a constant supply of nutrition in order to be active," said Dr.

Cells are the basic units of structure and function of all organisms. These cells are grouped together to form more complex structures: tissues, organs, and organs systems. Animals and plants are very different organisms and yet, they are both made up of parts that are organized similarly.

Although there are many types of cells in the human body, they are organized into four broad categories of tissues: epithelial, connective, muscle, and nervous. Each of these categories is characterized by specific functions that contribute to the overall health and maintenance of the body.

Organ systems. Organs are grouped into organ systems, in which they work together to carry out a particular function for the organism. For example, the heart and the blood vessels make up the cardiovascular system.

Some examples of organs are the heart, lungs, skin, and stomach. When organs work together, they are called systems. For example, your heart, lungs, blood, and blood vessels work together. They make up the circulatory system.

Tissues are groups of cells that perform a common function, such as skeletal muscle tissue or fat tissue. They are therefore larger than cells. Organisms are made up of organs which are made up of tissues, and are therefore larger than tissues. ... Population, organism, tissue, cell, organelle, molecule.

They are therefore smaller than cells. ... Tissues are groups of cells that perform a common function, such as skeletal muscle tissue or fat tissue. They are therefore larger than cells. Organisms are made up of organs which are made up of tissues, and are therefore larger than tissues.

Every organ belongs to a single organ system. All organs and organ systems are interdependent. If an organ in one system fails, other systems will not be affected. An organ system consists of only one organ.

Organ, in biology, a group of tissues in a living organism that have been adapted to perform a specific function. In higher animals, organs are grouped into organ systems; e.g., the esophagus, stomach, and liver are organs of the digestive system.

Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.

Aging changes in organs, tissues, and cells. All vital organs begin to lose some function as you age during adulthood. Aging changes occur in all of the body's cells, tissues, and organs, and these changes affect the functioning of all body systems. Living tissue is made up of cells.

The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.

Vital organs These are the brain, heart, kidneys, liver and lungs. The human brain is the body's control center, receiving and sending signals to other organs through the nervous system and through secreted hormones.
