How Do You Spell ARTERIAL SYSTOLE?

Pronunciation: [ɑːtˈi͡əɹɪə͡l sˈɪstə͡ʊl] (IPA)

Arterial systole refers to the contraction of the heart's ventricles, resulting in the ejection of blood into the arteries. The spelling of this term is as follows [ahr-teer-ee-uh l sis-toh-lee], with the emphasis on the second syllable "teer". The "ar" sound is pronounced like "air," the "ee" is pronounced like "eee," and the "oh" is pronounced like "oh" in "note." The final "e" in "systole" is silent. The correct spelling of medical terms is crucial to ensure clear communication between healthcare professionals.

ARTERIAL SYSTOLE Meaning and Definition

1. Arterial systole refers to the phase of the cardiac cycle in which the ventricles of the heart contract and pump blood out into the arteries. It is a crucial component of the overall circulatory process that ensures the efficient delivery of oxygen and nutrients to various tissues and organs throughout the body.

   During arterial systole, the ventricles forcefully contract, generating pressure that propels blood out of the heart and into the arterial system. This contraction is stimulated by electrical impulses originating in the sinoatrial (SA) node, which is the natural pacemaker of the heart. As the ventricles contract, the pressure within them rises, causing the semilunar valves leading into the arteries to open and allowing blood to be ejected.

   The blood that is ejected during arterial systole is rich in oxygen, having previously undergone oxygenation in the lungs, and it also contains essential nutrients derived from digestion. This oxygenated and nutrient-rich blood is propelled through the arteries, which branch out extensively to reach every tissue and organ in the body.

   Arterial systole is a vital stage of the cardiac cycle that ensures the continuous circulation of blood and proper oxygenation of tissues. It is followed by ventricular diastole, the relaxation phase of the cardiac cycle when the ventricles refill with blood. The alternation between systole and diastole helps maintain blood flow and enables the body to perform necessary physiological functions.

2. The contraction of an artery following its dilatation by the pulse wave.

Etymology of ARTERIAL SYSTOLE

The word "arterial systole" is a combination of two terms: "arterial" and "systole".

1. Arterial: The term "arterial" comes from the Latin word "arteria", which means "air tube" or "windpipe". In ancient times, arteries were thought to carry air and not blood. Over time, the term "arteria" evolved to refer to the tubes that carry blood away from the heart.

2. Systole: The term "systole" comes from the Greek word "sustolḗ", meaning "contraction" or "puling together". In medical context, systole refers to the phase of the cardiac cycle when the heart muscle contracts to pump blood out of the chambers.

When combined, "arterial systole" refers to the contraction phase of the cardiac cycle specifically in the arteries.
