(9/25/25) formative assessment assignment: chapter 6 the muscular system part 1 (suggested
6 of 16
muscle functions
all muscle types produce movement, but skeletal muscle plays three other important roles in the body as well. it maintains posture and body position,
stabilizes joints, and ( 1 ) heat. lets take a look.
produce movement
skeletal muscles are responsible for our bodys mobility, including all locomotion (walking, swimming, and cross - country skiing, for instance) and
manipulating things with your agile upper limbs. they enable us to respond quickly to changes in the ( 2 ) environment. for example, their
speed and power enable us to jump out of the way of a runaway car and then follow its flight with our eyes. they also allow us to express our emotions with
the silent language of smiles and frowns
they are distinct from the smooth muscle of blood vessel walls and ( 3 ) muscle of the heart, which work together to circulate blood and
maintain blood pressure, and the smooth muscle of other hollow organs, which forces fluids (urine, bile) and other substances (food, a baby) through ( 4
) body channels. maintain posture and body position we are rarely aware of the workings of the skeletal muscles that maintain body posture. yet
they function almost continuously, making one tiny ( 5 ) after another so that we maintain an erect or seated posture, even when we slouch,
despite the never - ending downward pull of gravity.

o 1. generates 2. external 3. cardiac 4. internal 5. adjustment

Explanation:

1. Muscles generate heat as a function, so "generates" is correct for (1).
2. Skeletal muscles help respond to the external environment, so "external" for (2).
3. The heart muscle is cardiac muscle, so "cardiac" for (3).
4. Smooth muscles in hollow organs force substances through internal body channels, so "internal" for (4).
5. Skeletal muscles make tiny adjustments to maintain posture, so "adjustment" for (5).

Answer:

1. generates 2. external 3. cardiac 4. internal 5. adjustment
