What else can I help you with?
How does contraction of the muscles of the esophagus stomach and intestines help in digestion?
no
Why would the stomach take a long time to digest food without the muscles?
Muscles cause contraction. Contraction aides in moving the food along.
What is the process that the stomach muscles contract to propel food?
The process by which stomach muscles contract to propel food is called peristalsis. This rhythmic contraction of the smooth muscles in the stomach walls mixes food with gastric juices and pushes it toward the small intestine. The contractions are coordinated by the enteric nervous system and occur in waves, ensuring that the food is thoroughly processed before moving on for further digestion.
Muscles found only in the walls of your heart?
Cardiac muscles are found only in the walls of the heart. They are specialized muscles that contract and relax to pump blood throughout the body, and they are involuntary, meaning we cannot control their contraction.
What is vasomotor tone?
Constant level of nervous stimulation to the muscles in the blood vessel walls. This gives the muscles a resting level of contraction.
What nerve innervates the visceral muscles of the stomach causing contraction and hence motility?
The Vagus Nerve.
Why does contraction of the muscles of the esophagus stomach and intestines help in digestion?
These muscles push down the food. the stomach turns the proteins into amino acids and carbs into sugars and fats into glycerol and fatty acids
Do all muscle cells contain striations?
Skeletal and cardiac muscles are striated. Smooth muscles found in the walls of hollow organs such as the stomach and in the walls of blood vessels are unstriated.
If Ivan flexes his stomach muscles without moving them for 30 seconds he is performing an?
If Ivan flexes his stomach muscles without moving them for 30 seconds, he is performing an isometric contraction. This type of contraction involves tensing the muscles without changing their length or causing any joint movement. Isometric exercises can help improve muscle strength and endurance.
How do smooth muscles and sphincters keep food moving in one direction throughout the digestive system?
by peristalsis which is the rhythmic, involuntary contraction of the smooth muscles in the walls of digestive organs.
What muscles are same as stomach muscles?
Stomach muscles
Blood vessels are what type of muscles?
The walls of blood vessels have smooth muscle, which allow contraction and dilation (for example, in response to temperature changes.
