- - - - . Another function of the cardiovascular system is also to transport carbon dioxide, a waste product, from the entire body to the heart and lungs to finally eliminate carbon dioxide through respiration
  - - - When it reaches the lungs, the cardiovascular system begins to function, since it is there where the non-oxygenated blood is oxygenated and returns to the heart
        
        It is then when in the cardiovascular system the heart pumps the blood rich in oxygen and in each beat it makes it flow through a network
        
        of blood vessels - the arteries - and branches until it reaches the tissues, including the organs. , muscles and nerves throughout the body
        
        the blood reaches the capillaries in the tissues, oxygen is released, which the cells use to produce energy
        
        These cells release waste products, such as carbon dioxide and water, which are absorbed and transported by the blood
        
        The used (or "deoxygenated") blood then travels the vascular system through the veins and back to the heart

  - - - is a pump that is divided into left and right sides. It has walls made of muscle that contracts to pump cardiovascular blood to the blood vessels throughout the body
        
        weighs approximately 300g and is located on the left side of the thoracic cavity of the human body, the heart is surrounded by a protective membrane called the pericardium
        
        pumps oxygenated blood and then returns and pumps the already deoxygenated blood to the lungs, normally that does it between 60 to 100 times per minute. For 24 hours a day
    - - It carries oxygen and nutrients and pumps the blood throughout the body
        
        is under pressure due to the pumping of the heart and the size and flexibility of the arteries
    - - They carry blood from the body's periphery to the heart
        
        . They are easily expandable and their function is reserve
        
        The veins of the systemic circulation carry little oxygen in the blood
        
        and those of pulmonary circulation, it is blood rich in oxygen.
    - - They carry blood from the heart to the rest of the body and the veins carry from the body to the heart
        
        the circulatory system carries oxygen, nutrients and molds to the cells and eliminates all waste such as carbon dioxide
- - - - It is made up of the body´s bones (which make up the skeleton), muscles, tendons, ligaments, joints, cartilage and other types of connective tissue
  - - - produces the movement
      - serves as protection
      - hold posture
      - provides heat, due to its abundant irrigation, friction and energy consumption
      - displacements
  - - - make up body mass are fast and strong acting but are no maintained over time
      - central nervous system and is of voluntary control
    - - forms the covers of the organs
      - they are slow acting and keep a rhythm
      - autonomic nervous system
      - lacks voluntary control
    - - heart muscle, autonomic nervous system
      - lacks voluntary control
- - - - NOSE
        
        filter, warm and moisten the air you breathe. Nose hairs and mucus produced by cells in the nose trap airborne particles and prevent them from entering the lungs
      - PHARYNX AND LARYNX
        
        Air passes through thin tissues in the larynx and produces sound
      - WINDPIPE
        
        long tube leading to the lungs, where it divides into the bronches
        
        right and left
      - BRONCHES
        
        branch into smaller bronchioles in each lung
      - DIAPHRAGM
        
        muscular sheet found across the bottom of the rib cage
        
        When it contracts, the volume of the chest increases and the lungs take in air
        
        When you relax, the volume of the chest decreases and the air is pushed out of the lungs.
      - EPIGLOTTIS
        
        covers your windpipe when you eat or drink. The muscle that controls the epiglottis is involuntary and prevents food from entering your lungs or windpipe
      - ALVEOLES
        
        small sacs found at the end of the bronchioles
        
        oxygen is exchanged for carbon dioxide
        
        oxygen enters the blood and carbon dioxide is removed from the blood
        
        Gases are exchanged between the blood and the alveoli through simple diffusion.
- - - - Sympathetic System:
        It is responsible for activating the body, so which increases energy expenditure and usually run during the day.
    - - Parasympathetic System:
        Produces the opposite effects to nice, relax the body, reduces the consumption of power and usually works at night.
  - - - The nervous system is divided into two large subsystems:
        
        nervous system central (CNS) composed of the brain and spinal cord.
        
        nervous system peripheral (PNS), within which are included all the nervous tissues located outside the central nervous system.
        
        The CNS is made up of the brain and spinal cord.
        
        In addition, the CNS is also the source of our thoughts, emotions and souvenirs. After integrating the information, through motor functions that travel through
        
        Nerves of the PNS execute an adequate response
