1
,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.
White Blood Cells (Leukocytes) Answer: Cells of the immune system that fight infection and
disease.
What is the main function of monocytes? Answer: Clean debris.

, What do lymphocytes do? Answer: T & B cells provide immune support.
What is the role of eosinophils? Answer: Defend against allergic reactions.
What do basophils do? Answer: Promote inflammation, e.g., release histamine.
What is the function of neutrophils? Answer: Respond to infection.
Monkeys Like Eating Bees Naturally Answer: Monocyte, Lymphocyte, Eosinophil, Basophil,
Neutrophil
Agglutination Answer: Clumping of red blood cells when incompatible blood types mix
Antigen Answer: Marker on red blood cells that shows blood type
Antibody Answer: Protein in plasma that attaches to specific antigens
What is Hemolytic Disease of the Newborn (HDN)? Answer: When Rh antibodies attack fetal
blood
What determines blood type Answer: A and B antigens on red blood cells
What is Type A blood Answer: Has A antigen; fights B
What is Type B blood Answer: Has B antigen; fights A
What is Type AB blood Answer: Has A & B antigens; fights nothing
What is Type O blood Answer: Has no antigens; fights A & B
What happens if incompatible blood types mix Answer: Agglutination (clumping of blood)
The primary function of the ________________ is to deliver blood to the brain Answer:
Carotid
Which blood vessel delivers blood directly into the right atrium Answer: Vena Cava
One of the primary functions of blood is to deliver oxygen-rich blood to the body's tissues. This
is accomplished by ________________, which contain the oxygen-carrying protein called
___________________. Answer: Erythrocytes; hemoglobin
Which of the following comparisons between arteries and veins is true
- Veins have valves, and arteries do not.
- Veins carry freshly oxygenated blood from tissue back to the heart, while arteries carry
oxygen-depleted blood away from the heart.
-Veins have thick, muscular walls, while arteries have thin, more compliant walls.
-Veins have a smaller diameter than arteries. Answer: Veins have valves, and arteries do not.
A decrease in the amount of hemoglobin in the blood would result in Answer: Decreased
oxygen-carrying capacity
