Q

Cardiovascular system

Defense

A

Blood components help defend against disease and mend damaged blood vessels

  • white blood cells defend us against disease and invading pathogens
  • clotting: blood clotting cells mend damaged blood cells

Q

Muscle action

Origin

A

Origin or head of the muscle is the beginning of the muscle

The origin of a muscle is the proximal or inferior attachment and is usually fixed/stable.

19
Q

Muscle action

Insertion

A

Insertion or end of muscle

The insertion of a muscle is the distal or superior attachment and moves toward the origin during contraction

20
Q

Muscle action

Belly

A

The portion of muscle between the attachments

Contractile portion of the muscle

21
Q

Muscle action

Action of the muscle

A

The movement that occurs when the belly pulls the insertion toward the origin.
