Page 24 Excretory Organ Function Superior vena cava Inferior vena cava Right atrium Right ventricle pulmonary arteries pulmonary veins Left atrium Left ventricle Aorta Valves Septum Large Vein, carries deoxygenated blood from the upper half of the body to the heart's right atrium. Large Vein, carries deoxygenated blood from the lower half of the body to the heart’s right atrium. Right upper chamber that receives deoxygenated blood Right lower chamber that pumps deoxygenated blood to lungs Carries blood from the heart to the lungs Carries blood from the lungs to the heart Left upper chamber that receives oxygenated blood Left lower chamber that pumps oxygenated blood to the body Main artery coming directly out of the left side of the heart Structures in the heart that control the flow of blood (one-way) Wall dividing the left and right sides of the heart

Poor Gills Oxygen Yes The chambers are not separated

2 1 3 Frog Salamanders Newt

Poor R. Atrium Oxygen Yes Only 1 ventricle, blood from body and lungs mixes

2 1 3 Snake Lizard Turtle Poor Oxygen Yes Partial septum

Septum Keeps the blood partially separated B/c of the partial septum valve

2 2 4 Robin Dove Finch Human Whale Dogs

Septum Left b/c it pumps a greater distance Both sides are pumping simultaneously

Efficient design of heart- separates oxygen rich and oxygen poor blood Prevents backflow of blood

ACE BDF It supplies the heart muscle with oxygen and nutrients for cellular respiration Prevents backflow of blood

Left ventricle- pumps to entire body No, pulmonary artery carries oxygen poor blood Increase blood pressure The oxygen poor blood and oxygen rich blood would mix, circulating poor blood to body cells and rich blood to lungs
