coronary sinus

Thrombocytes are also called ________. Select one: a. white blood cells b. megakaryocytes c. red blood cells d. platelets

d. platelets

___________________ circulation is the system that carries low-oxygen blood from the heart to the lungs, then back to the heart after oxygenation occurs. Select one: a. lymphatic b. systemic c. cardiac d. pulmonary

d. pulmonary

The tricuspid valve is located between the ________________ & __________________. Select one: a. left atrium, left ventricle b. right atrium, superior vena cava c. right ventricle, pulmonary trunk d. right atrium, right ventricle

d. right atrium, right ventricle

Fill in the missing words to correctly trace blood flow through the right side of the heart. Low oxygen blood flow from the right atrium through the (tricuspid valve or semi-lunar valve), where it enters the (right ventricle or pulmonary valve). From there, it travels through the (semi-lunar valve or tricuspid valve) into the (lungs or legs), which becomes the pulmonary arteries. Then, the blood enters the (legs or lungs) to become oxygenated before returning back to the heart.

tricuspid valve right ventricle semi-lunar valve pulmonary trunk lungs

The pulmonary __________ carry oxygen-rich blood back to the heart.

veins
