When cells work together to perform a specific function What is this called?

When specialized cells work together to perform a specific function, they are known as a tissue. There are four basic types of tissues: muscle, epithelial, connective, and nervous tissue.

What do we call a group of cells that are working together for a combined function?

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.

What is a group of cells that work together to perform a certain function in a plant known as?

A tissue is a group of similar cells that work together to carry out a particular function. A group of differentiated cells forms a tissue. A tissue is a group of similar cells that work together to do a particular job.

What organs work together to perform a specific function?

In an organ, different tissues work together to carry out a particular function. The brain controls thoughts, memory and other organs. The heart pumps blood around the body. The lungs separate oxygen from the air and remove carbon dioxide from the blood.

What’s a group of organs that work together called?

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.

What is the combined primary function of the respiratory and circulatory systems?

KEY CONCEPT The respiratory and circulatory systems bring oxygen and nutrients to the cells. The respiratory and circulatory systems work together to maintain homeostasis. The respiratory system moves gases into and out of the blood. The lungs contain the bronchi, bronchioles, and alveoli.

Which two body systems work together to help remove waste products from blood?

more human body questions

Question Answer
Two body systems work together to help remove waste products from blood. What are these two systems? circulatory and excretory
One of the functions of the endocrine system in the body is to — produce enzymes to help digest food

What two systems work together for vertebrates to exchange?

Gas exchange between tissues and the blood is an essential function of the circulatory system. In humans, other mammals, and birds, blood absorbs oxygen and releases carbon dioxide in the lungs. Thus the circulatory and respiratory system, whose function is to obtain oxygen and discharge carbon dioxide, work in tandem.

How does gas exchange occur in animals?

In animals, gas exchange follows the same general pattern as in plants. Oxygen and carbon dioxide move by diffusion across moist membranes. In simple animals, the exchange occurs directly with the environment. Hemoglobin binds loosely to oxygen and carries it through the animal’s bloodstream.

What is human gas exchange?

During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

Is ventilation a gas exchange?

Ventilation: The exchange of air between the atmosphere and the lungs – achieved by the physical act of breathing. Gas Exchange: The exchange of oxygen and carbon dioxide between the alveoli and bloodstream (via passive diffusion)

What factors affect the rate of gas exchange?

Fick’s law gives us a number of factors that affect the diffusion rate of a gas through fluid:

  • The partial pressure difference across the diffusion barrier.
  • The solubility of the gas.
  • The cross-sectional area of the fluid.
  • The distance molecules need to diffuse.
  • The molecular weight of the gas.

How does exercise improve gas exchange?

When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute (12 litres of air) when you are resting, up to about 40–60 times a minute (100 litres of air) during exercise.
