The process of continuously passing through a closed system, returning to the original point while repeating the journey.
A repeated series of changes or movements, such as the natural processes involving natural elements like water or air.
The movement and distribution of fluids within an organism, specifically referring to how blood and lymph circulate to nourish body organs and remove waste.
Example:
血液は体内を循環する。
A situation in which two or more negatively interacting elements perpetually reinforce each other, creating a continuous cycle of unfavorable outcomes.
A state where one adverse condition leads to another, which in turn causes the original situation to worsen, resulting in an endless loop of detrimental effects.
An interconnected series of problems where each issue contributes to the persistence and escalation of the others, making it difficult to break free from the cycle.
A feedback loop of negative consequences where each element influences and exacerbates the others, leading to an ongoing pattern of decline or dysfunction.
Example:
賃金と物価の悪循環を断ち切ることは困難だ。
The process by which blood continuously moves through the vascular system in a specific direction, ensuring the delivery of oxygen and nutrients to tissues while removing waste products.
A physiological mechanism in which blood flows through a closed circulatory system, characterized by two main circuits: one that brings oxygenated blood from the heart to the body (systemic circulation) and another that carries deoxygenated blood to the lungs for reoxygenation (pulmonary circulation).
The dynamic and regulated movement of blood within the body, involving a network of vessels that connect the heart, lungs, and other organs, vital for maintaining bodily functions and homeostasis.
An organ system responsible for the transportation of nutrients and oxygen to various parts of the body while also removing waste products generated by the body's tissues. This includes structures such as the heart, blood vessels, and lymphatic system.
A complex network within the body that functions to ensure that essential substances are evenly distributed to organs and tissues, while simultaneously facilitating the removal of metabolic byproducts, thereby maintaining homeostasis.
The collective term for organs that work together to regulate blood flow and lymphatic circulation, playing a vital role in overall health by supporting various physiological processes through continuous movement of fluids.
