Question

Explain how the biceps and triceps muscles work as a pair to bend and straighten the arm at the elbow.


can someone help me answer this?????????

Answer 1

Give an example of the ways in which organ systems work together to maintain the human body. Draw connections between at least three organ systems.

Identify a joint in the body that serves as the fulcrum of a first-class lever, and explain why it is classified this way.

please someone help??????????

Answer 2

For the first one,
as the bicep contracts it pulls your forearm upwards
as the tricep contracts it pulls the forearm downwards

there is no pushing involved as the only foreceful movement done is in the form of pulling as contraction occurs.
And for the second one,
Digestive system breaks down food into glucose
Circulatory system transports glucose around the body so it can be made into ATP
Muscles use ATP to move.
I hope that somewhat helps you. c:
