Question

The vena cava brings blood loaded with co2 to the (a)________________, that delivers the blood to the (b)______________. this chamber pumps the co2 loaded blood through the (c)_____to the d)____________ where co2 is released and red blood cells take on (e)_________________. blood then returns to the heart through the (f)________________ and enters the (g) ___________ . this chamber delivers blood into the (h)_____ that pumps it through the (i)______________________ to all parts of the body. the walls of the (j)_____are much thicker than the walls of the (k)___________. this thick, muscular wall allows for effective circulation of blood through the (l) _____circuit.

Answer 1

The vena cava brings blood loaded with CO2 to the right atrium, that delivers the blood to the right ventricle. This chamber pumps the co2 loaded blood through the pulmonary artery to the lungs where co2 is released and red blood cells take on oxygen. Blood then returns to the heart through the pulmonary vein and enters the left atrium. This chamber delivers blood into the left ventricle that pumps it through aorta to all parts of the body.

The walls of the left ventricle are much thicker than the walls of the right ventricle. This thick, muscular walls allows for effective circulation of blood through the cardiac circuit.
