Red and White Blood Cells

Oxygen transport in humans involves the bonding of oxygen with

• white blood cells

• platelets

• hormones

• hemoglobin molecules

Which part of the blood is correctly paired with its function?

• red blood cells - fight infection

• plasma - transports wastes and hormones

• platelets - produce antibodies

• white blood cells - carry oxygen

Which statement correctly describes the activities of the components of human blood shown in the diagram?

• Both A and B function in immune responses, and C transports oxygen

• A, B, and C are able to synthesize hemoglobin

• Both B and C provide immunity, and A transports nutrients

• A transports oxygen, B starts clots, and C functions in immune response to fight infections

Bleeding from a small cut soon stops due to the release of enzymes from

• platelets

• activated antibodies

• hemoglobin

• white blood cells

The diagram below represents several human blood cells as observed through a compound microscope. Which function is associated with cell X?

• antibody production

• oxygen transport

• phagocytosis

• peristalsis

A function of the white blood cells is to

• transport oxygen to body cells

• produce hormones that regulate cell communication

• carry glucose to body cells

• protect the body against pathogens
