BLOOD AND CIRCULATION!

Right Atrium - recieves deoxygenated blood from the great veins (venae cavae)

Great Viens - return deoxygenated blood to the heart from the body.

Large valve (triculspid) - prevents backflow of blood into the atrium which the ventricle contracts.

Right ventricle - less muscular chamber which pumps deoxygenated blood to the lungs through the pulmonary artery.

Semilunar valve - prevents backflow of blood into the ventricle when the heart relaxes (also in the aorta)

Aorta - Great Artery carrying oxygenated blood to all parts of the body.

Left Atrium - Receives oxygenated blood prom the pulmonary veins.

Left Ventricle - Very muscular chamber which pumps oxygenated blood to the rest of the body.

Pulmonary veins - Carry oxygenated blood back from the lungs to the heart

Large Valve (Bicuspid) - prevents backflow of blood into Atrium when the ventricle contracts.

Heart Muscle - Contracts rhythmically and whithout fatiguing to pump blood.



THE BLOOD!

  • Plasma: yellow liquid which transports dissolved food molecules, carbon dioxide and urea as well as blood cells. made up mainly of water.
  • Red blood cells:  are made in the bone marrow, have no nucleus for maximum oxygen
