It receives deoxygenated blood from the body
Explication
The right atrium's primary role is to receive deoxygenated blood from the body via the superior and inferior vena cavae, acting as the entry chamber for blood returning to the heart from systemic circulation.
Left Atrium
Explication
The Left Atrium is responsible for receiving oxygen-rich blood from the lungs via the pulmonary veins, which is critical for systemic circulation.
1866
Explication
Mendel published his work on inheritance patterns in 1866, which is a well-documented historical fact. The other dates are either before or after his publication and are plausible distractors but incorrect.
It circulates blood to the entire body requiring higher pressure.
Explication
The left ventricle has a thicker wall because it must generate higher pressure to pump blood through the systemic circulation to the entire body.
1865
Explication
Gregor Mendel published his work on inheritance patterns in 1865, laying the foundation for genetics.
Two different alleles for a gene
Explication
Heterozygous means having two different alleles for a gene, one dominant and one recessive, which influences trait expression.
Prevent backflow of blood between chambers
Explication
Valves prevent backflow of blood between chambers and ensure unidirectional flow, maintaining efficient circulation.
Recessive inheritance
Explication
Recessive inheritance requires both alleles to be recessive (homozygous) for the trait to be expressed.

Heart chambers — roles?
Atria receive, ventricles pump blood.
Right Atrium — role?
Receives deoxygenated blood from body.
Alleles — dominant vs recessive?
Dominant masks recessive; expressed in heterozygotes.
