Category 1: Blood Pathway
This chamber of the heart receives deoxygenated blood from the body.
right atrium
These vessels carry blood away from the heart.
arteries
The cells responsible for carrying oxygen.
red blood cells (erythrocytes)
right side
oxygenated blood
What is the pulmonary artery?
Blood leaving the right ventricle travels through this artery to reach the lungs.
capillaries
Cells that fight infection in the body.
white blood cells (leukocytes)
The blood circulation is _______, thanks to the valves that prevent its back flow.
unidirectional
poor oxygen blood is called this.
deoxygenated blood
Oxygenated blood returns from the lungs to the heart via this vessel.
pulmonary vein
veins
These fragments help blood clot.
platelets
Valves prevent this in the heart.
backflow of blood
The systemic circulation carries blood between the heart and ________________.
the body
After leaving the left ventricle, blood enters this largest artery in the body.
aorta
This vein carries blood from the lower body to the heart.
inferior vena cava
The liquid portion of blood that carries nutrients, hormones, and waste.
plasma
The valves on the right side of the heart is:
pulmonary valve and tricuspid valve
Pulmonary circulation moves blood between the heart and this organ.
the lungs
Name the full path of blood circulation starting from the right atrium and ending back there.
right atrium → right ventricle → pulmonary artery → lungs → pulmonary vein → left atrium → left ventricle → aorta → body → superior/inferior vena cava → right atrium
____________ have thick walls to handle oxygenated blood.
arteries
This protein helps to rebuild tissue when an injury occurs.
fibrinogen
The whitish strings in the ventricles observed in the pig heart, were the_______
valves of the heart
Coronary arteries flow only within this organ
the heart
