The Multifunctional Body Systems

By, Yamonie Jenkins

The Body Systems -  3 body systems: -  Circulatory -  Respiratory -  Digestive

Circulatory System -  Transports throughout the entire body

-  Moves nutrients, water, and oxygen to body cells

-  carries away wastes

Respiratory System -  Organs in the body that help breathe

-  Delivers oxygen to the body

-  Takes away carbon dioxide

Human Circulatory System -  4 chambered heart -  2 atria and 2 ventricles -  Transports blood to different

regions -  Arteries, Veins, and Capillaries -  Deoxygenated and Oxygenated

blood

Fish Circulatory System -  2 chambered heart -  1 atrium and 1 ventricle -  Small gill capillaries

increase flow resistance -  Low blood pressure

limits O2 intake

Frog Circulatory System -  3 chambered heart

-  2 atria and 1 ventricle -  Partially separate pulmonary and systemic circulations -  oxygenated blood and deoxygenated blood mix

Human Respiratory System -  Tidal ventilation of lungs -  Inhalation and exhalation -  Contraction of diaphragm -  Gas exchange -  Alveoli provides vast

surface

Fish Respiratory System -  Internal Gills -  High effort needed to

ventilate -  High density and viscosity

of water -  Unidirectional flow of

water -  Countercurrent exchange

Frog Respiratory System

-  Buoyancy while swimming

-  Throat sac

-  Breathes through nose

-  Diffusion through skin and

mucus glands
