The heart and kidney are both classified as vital organs necessary for human survival [1], [2]. They are functionally linked through their roles in blood pressure regulation [3], [4], [5] and are frequently compared in studies regarding physiological evolution [6], biological sex differences [7], [8], and pathological responses like fibrosis [9].

A Copernican Approach to Brain Advancement: The Paradigm of ... frontiersin.org 5 facts
claimBlood pressure regulation is a physiological phenomenon studied under the homeostatic paradigm, involving the heart (as a pump), blood vessels (which constrict and relax), and kidneys (which manage blood volume by filtering fluid and conserving sodium).
claimHomeostasis models the cause of hypertension by pointing to abnormal functionality of the heart, blood vessels, kidneys, or molecular signaling, whereas allostasis explains that the brain deliberately directs these organs on an anticipatory basis to elevate blood pressure for the delivery of resources like glucose and oxygen to large muscle groups.
claimIn scientific research, the brain is considered the organ of behavior, analogous to how the heart, vascular system, and kidneys are considered the organs of blood pressure.
claimHomeostatic schematics of blood pressure regulation typically highlight the brainstem centers of the autonomic nervous system, direct neural control and afferent signaling between the brain, heart, and blood vessels, and neural ganglia at the kidneys.
claimThe adrenal glands, lungs, and liver are recognized as playing roles in the regulation of blood pressure alongside the heart, vessels, and kidneys.

Is There a Male Brain and a Female Brain? | Child & Family Blog childandfamilyblog.com 2 facts
claimResearch indicates that there are far more similarities between female and male brains than there are differences, and brains are more comparable to organs like the heart and kidney than to reproductive organs.
measurementWhile the average size of women's and men's brains differs by 11%, the size of other human organs differs by larger percentages: hearts by 17%, lungs by 23%, livers by 14%, pancreases by 18%, kidneys by 19%, and thyroids by 25%, with all these organs being larger in men.
The Center for Inflammation Science and Systems Medicine wertheim.scripps.ufl.edu 1 fact
claimThe body's response to persistent inflammation in a specific organ is the development of scar tissue or fibrosis, which can occur in the heart, lung, liver, kidneys, or bowel and reduce organ function.
Systems and organs | Anatomy and Physiology | Research Starters ebsco.com 1 fact
claimThe brain regulates blood pressure by monitoring sensors in the body and signaling the cardiovascular system to slow the heart and open blood vessels, and signaling the kidneys to excrete fluid when pressure is too high.
Homeostasis: The Underappreciated and Far Too Often ... - Frontiers frontiersin.org 1 fact
referenceThe cardiorespiratory response to exercise demonstrates hierarchical control of homeostatic regulation: the first level consists of tissues and organs of the cardiovascular and respiratory systems (heart, lung, blood vessels, kidneys, and endocrine glands); the second level consists of the baroreceptor and cardiorenal reflexes; and the third level of regulation occurs within the medulla (NTS) of the central nervous system where sensory information is processed and efferent responses are initiated.
The battle of the sexes: Whose brain comes out on top? pennneuroknow.com 1 fact
measurementMen's internal organs are, on average, larger than women's: hearts are 17% larger, lungs are 23% larger, livers are 14% larger, the pancreas is 18% larger, and kidneys are 19% larger.
Evolutionary psychology - Wikipedia en.wikipedia.org 1 fact
claimEvolutionary psychologists argue that the mind possesses modularity, meaning different psychological mechanisms evolved to solve distinct adaptive problems, similar to how physiological organs like the heart, liver, and kidneys evolved to perform specific functions.
