Muscles located in the walls of the small intestine help push digested material along. Muscles located in the walls of arteries help push blood along. Based on this information and your understanding of muscle types, which of the following statements is correct?

Both sets of muscles are involuntary and smooth.
Both sets of muscles are voluntary and smooth.
Both sets of muscles are smooth, although one set is voluntary, and the other set is involuntary.
Both sets of muscles are voluntary, although one set is striated, and the other set is smooth.

i think its A but can someone confirm?

The answers to the whole test are

D
B
A
A

yes, involuntary and smooth.

thanks

To confirm the correct answer, let's analyze the information provided. The question states that muscles located in the walls of the small intestine help push digested material along, and muscles located in the walls of arteries help push blood along.

Based on this information, we can conclude that both sets of muscles mentioned in the question are muscles of involuntary type, as they are not under conscious control.

Now let's consider the types of muscles that exist in the body. There are three types: smooth muscles, cardiac muscles, and skeletal muscles. Smooth muscles are non-striated, while cardiac and skeletal muscles are striated.

Applying this knowledge, we can rule out options C and D, as they mention voluntary muscles.

Option B states that both sets of muscles are voluntary and smooth, which contradicts the fact that the mentioned muscles are involuntary.

Therefore, the correct answer is option A: Both sets of muscles are involuntary and smooth. This aligns with the nature of the muscles described in the question.
