Explain how the contraction and relaxation of the chamber walls move blood through he heart?
Contraction: 'eject' the blood out of the heart due to reduce in size of heart chamber. From left ventricle, the blood will be pushed into the systemic circulation whereas on the right ventricle, the dehydrogenated blood is pushed into the pulmonary circulation (ie: lung).
Relaxation: allow the heart to be filled with blood. Freshly oxygenated blood from the lung will move into left atrium and so thus the left ventricle whereas on the right side of the heart, blood now started to fill in the right atrium and the right ventricle again.

Describe the pumping action of the heart?
The pumping action involves the heart's chamber contracting and relaxing. The heart beat is one cycle of the heart going through this contraction and relaxation while pumping blood.
What is the difference between a heart beat and a pulse?
A heartbeat is the contraction and relaxation of the heart muscle, while a pulse is the rhythmic expansion and contraction of an artery as blood is pumped through it by the heart.
Active exercises-definition and its type?
Active exercise is the movement of a part of the body through voluntary contraction and relaxation of the muscles in the area.
What is the main function of the redum?
The main function of the rectum is to store feces until they can be eliminated from the body through the process of defecation. The rectum also helps to control the urge to defecate through the relaxation and contraction of its muscles.
The primary function of the myocardial working cell include a automaticit b regeneration contraction and relaxation impulse propagation?
The primary function of myocardial working cells in the heart is contraction and relaxation, which allows the heart to pump blood efficiently through the body. These cells also play a role in conducting electrical impulses to maintain the heart's rhythm. While these cells do not have the ability to regenerate significantly, they can adapt and hypertrophy in response to increased workload or damage.
What happens to the volume of blood in the ventricle during the period of isovolumetric contraction?
Both ventricular contraction and atrial diastole take place.
What moves food through the small intestine?
Peristalsis, which is the coordinated contraction and relaxation of muscles in the intestinal wall, moves food through the small intestine. This process helps to mix and propel the food along the digestive tract for absorption.
What is peristalsis's?
Peristalsis is a distinctive pattern of smooth muscle contractions that propels food through the esophagus and intestines.radially symmetrical contraction and relaxation of muscles which propagates in a wave down a muscular tube, in an anterograde fashion.
What is peristalsis for?
peristalsis is basically the contraction and relaxation of muscle in digestive system which moves food along. for example if you have a staw with a drop of liquid in it, and you squeeze the straw just behind the liquid (this representing the muscular contraction), then the liquid will move away from where you are squeezing. so by the continuous contraction and relaxation of muscles in the walls of the digestive tract, movement of the food occurs. hence, the purpose of peristalsis is the movement of food along the digestive tract.
What is parastalisis?
It seems there may be a spelling error in your question. "Peristalsis" is the rhythmic contraction and relaxation of muscles in the gastrointestinal tract that helps push food and waste through the digestive system. It is essential for proper digestion and bowel movements.
How does an egg travel through the oviducts?
An egg travels through the oviducts of a female reproductive system by a process known as peristalsis, which is the rhythmic contraction and relaxation of the muscles in the oviduct. The egg is moved along the oviducts by this muscular activity until it reaches the uterus or is expelled during menstruation.
How Do Wrigglers Move?
Wrigglers move through a process called peristalsis, which involves the contraction and relaxation of their muscles in a wave-like motion. This movement allows them to propel themselves forward by pushing against the ground or other surfaces.
