The answer your looking for is muscles however these do activly stretch they can only contract. They are increaset in length by the contraction of a counteracting muscle.
Muscles.
Yes, our organs can move within the body, such as the lungs expanding and contracting during breathing, the heart beating, and the stomach and intestines contracting to help with digestion and moving food along the digestive tract. However, for the most part, organs have specific locations and are held in place by connective tissue to maintain their position within the body.
The skeletal system provides structure and support, protects internal organs, and produces blood cells. The muscular system allows for movement by contracting and relaxing muscles. The circulatory system transports oxygen, nutrients, and hormones throughout the body and removes waste products.
Sea slugs move by contracting and relaxing their muscles in a wave-like motion, known as peristalsis, which propels them forward. Some sea slugs also use cilia or small appendages on their body to help them glide or crawl along surfaces.
A muscle is a soft tissue that contracts to produce force and generate movement in the body. Muscles are made up of muscle fibers that are capable of contracting and relaxing in response to nerve signals. They are responsible for various functions such as movement, stability, posture, and heat production.
Muscle tissue is responsible for allowing the body to move by stretching and contracting. Muscles are made up of muscle fibers that can shorten (contract) and lengthen (stretch) to produce movement. Skeletal muscles, smooth muscles, and cardiac muscles are the three main types of muscle tissue in the body.
By contracting muscles in their body.
They allow your body to move.
A leech moves by extending and contracting its body in a wave-like motion, using its suckers to grip onto surfaces. On land, a leech can use its muscular body to inch forward and navigate uneven terrain by contracting and stretching its body segments. They move slowly and rely on moisture to prevent dehydration.
signals from the brain to the area and the muscle contracting.
Muscle tissue is the type of tissue that makes parts of the body move by contracting or shortening. It is composed of muscle fibers that have the ability to generate force and produce movement.
it allows you to move your body.... .... :)
A jellyfish swims by contracting and relaxing its bell-shaped body, pushing water out to propel itself forward. This movement is called pulsing, and allows the jellyfish to move through the water.
The muscular system allows you to move by contracting and relaxing muscles to generate motion. The skeletal system provides structure and support to the body, allowing muscles to pull on bones to create movement.
Muscles move an animal's skeleton by contracting and relaxing. When a muscle contracts, it pulls on the bones to create movement at the joints. Relaxing the muscle allows the skeleton to return to its original position.
Although the worm has not bones, it does have a hydro scleten which is basicly water and it allows the worm to move by contracting muscle's.
When stretching, you should not move quickly, norcomplete as many stretches as you can in a 5-minute period. These both defeat the purposes of stretching.
