Coordinated Functions of Circulatory and Respiratory Systems

Match the following parts of the circulatory system to its specific function.

• site of nutrient and gas exchange

• aorta

• biggest artery

• capillary

• takes oxygenated blood to the body

• vein

• pumps blood throughout the body

• artery

• returns deoxygenated blood to the heart

• heart

Match the following parts of the respiratory to its specific function.

• conveys air into the body

• alveoli

• carries air to the lungs

• nose

• site of gas exchange

• lung

• moves air from nose to the bronchi

• trachea

• facilitates gas exchange

• bronchus

Blood Flow starts when it enters through the ​ ​ (a)   then it goes into the ​ ​ (b)   then passing through the ​ (c)   valve and into the ​ (d)   and out of the heart and into the lungs through the ​ (e)  

• superior and inferior vena cava
• right atrium
• tricuspid
• right ventricle
• pulmonary arteries

Blood then goes into the ​ ​ ​ (a)   to pick up oxygen. From there, oxygenated blood returns to the heart through the ​ ​ (b)   and then into the ​ (c)   . Blood then passes through the ​ mitral valve and into (d)   . Oxygenated blood then gets pumped through the aortic valve and out of the heart through the ​ ​ (e)  

• left atrium
• lungs
• pulmonary veins
• left ventricle
• aorta

Oxygen-rich blood from the heart travels through the ​ (a)   and gets distributed to the different parts of the body. When oxygen-rich blood reaches a tissue it travels into one-cell-thick blood vessels known as ​ ​ (b)   which are the sites of nutrient and gas exchange. ​ Oxygen-poor blood returns to the ​ (c)   through the ​ (d)   . This oxygen-poor blood enters the heart through the ​ (e)   and the cycle begins again.

• capillaries
• arteriess
• veins
• superior and inferior vena cava
• heart
