Aorta - ANSWER ✔✔Largest artery; carries oxygen-rich blood from
the left ventricle to the body.
Inferior Vena Cava - ANSWER ✔✔Brings deoxygenated blood from
the lower body back to the right atrium.
Left Atrium - ANSWER ✔✔Receives oxygen-rich blood from the lungs
and sends it to the left ventricle.
Left Ventricle - ANSWER ✔✔Pumps oxygen-rich blood out to the
whole body.
,Mitral Valve - ANSWER ✔✔Valve between left atrium and left
ventricle; keeps blood flowing in one direction.
Pulmonary Artery - ANSWER ✔✔Carries oxygen-poor blood from the
right ventricle to the lungs.
Pulmonary System (Pulmonary Circulation) - ANSWER ✔✔Moves
blood from the heart → lungs → back to the heart.
Pulmonary Valve - ANSWER ✔✔Valve in the right ventricle that
opens into the pulmonary artery; prevents backflow.
Right Atrium - ANSWER ✔✔Receives oxygen-poor blood from the
body and sends it to the right ventricle.
Right Ventricle - ANSWER ✔✔Pumps oxygen-poor blood to the lungs
through the pulmonary valve.
Superior Vena Cava - ANSWER ✔✔Carries deoxygenated blood
from the head, neck, and arms to the right atrium.
Systemic System (Systemic Circulation) - ANSWER ✔✔Sends
oxygen-rich blood from the heart to the body and returns it back.
Tricuspid Valve - ANSWER ✔✔Valve between right atrium and right
ventricle; opens to let blood flow into the ventricle.
,Arteries - ANSWER ✔✔Blood vessels that carry blood away from the
heart to the body.
Veins - ANSWER ✔✔Blood vessels that carry blood back to the heart
from the body.
Capillaries - ANSWER ✔✔Tiny vessels where exchange happens —
they deliver oxygen/nutrients to tissues and pick up carbon
dioxide/waste.
Plasma - ANSWER ✔✔The liquid part of blood that carries cells,
nutrients, and waste.
Red Blood Cells (Erythrocytes) - ANSWER ✔✔Blood cells with
hemoglobin that carry oxygen from the lungs to the body.
