Question 1

Ligaments connect which two structures?

Accepted Answer

Bone to bone

Answer

Ligaments are strong, fibrous bands of connective tissue that primarily connect bones to other bones. Their main function is to stabilize joints, limit excessive movement, and prevent dislocations. In contrast, tendons connect muscles to bones.

Question 2

A person with AB- blood should not receive blood from which other blood type?

Accepted Answer

AB+

Answer

A person with AB- blood has A and B antigens but lacks the Rh factor. They can safely receive blood from A-, B-, O-, and AB- donors. However, they cannot receive AB+ blood because it contains the Rh antigen, which their immune system would recognize as foreign and attack, leading to a severe transfusion reaction.

Question 3

Accepted Answer

Pulmonary vein

Answer

The pulmonary veins return oxygen-rich blood from the lungs to the left atrium.

Question 4

Which of the following is not produced by an exocrine gland?

Accepted Answer

Adrenaline

Answer

Exocrine glands secrete their products, such as milk, digestive enzymes, or saliva, into ducts that lead to an external surface or internal cavity. Adrenaline (epinephrine) is a hormone produced by the adrenal glands, which are endocrine glands. Endocrine glands release their secretions (hormones) directly into the bloodstream, without using ducts.
