Spitting in the context of Hinko Smrekar

Fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges. The core principle of fluid balance is that the amount of water lost from the body must equal the amount of water taken in; for example, in humans, the output (via respiration, perspiration, urination, defecation, and expectoration) must equal the input (via eating and drinking, or by parenteral intake). Euvolemia is the state of normal body fluid volume, including blood volume, interstitial fluid volume, and intracellular fluid volume; hypovolemia and hypervolemia are imbalances. Water is necessary for all life on Earth. Humans can survive for 4 to 6 weeks without food but only for a few days without water.

Profuse sweating can increase the need for electrolyte replacement. Water-electrolyte imbalance produces headache and fatigue if mild; illness if moderate, and sometimes even death if severe. For example, water intoxication (which results in hyponatremia), the process of consuming too much water too quickly, can be fatal. Deficits to body water result in volume contraction and dehydration. Diarrhea is a threat to both body water volume and electrolyte levels, which is why diseases that cause diarrhea are great threats to fluid balance.

Ancient Egyptian creation myths are the ancient Egyptian accounts of the creation of the world. The Pyramid Texts, tomb wall decorations, and writings, dating back to the Old Kingdom (c. 2700–2200 BC) have provided the majority of information regarding ancient Egyptian creation myths. These myths also form the earliest recorded religious compilations in the world.

The ancient Egyptians had many creator gods and associated legends. Thus, the world or more specifically Egypt was created in diverse ways according to different parts of ancient Egypt. Some versions of the myth indicate spitting, others masturbation, as the act of creation. The earliest god, Ra and/or Atum (both being creator/sun gods), emerged from a chaotic state of the world and gave rise to Shu (air) and Tefnut (moisture), from whose union came Geb (earth) and Nut (sky), who in turn created Osiris, Isis, Set, and Nephthys. An extension to this basic framework was the Osiris myth involving Osiris, his consort Isis, and their son Horus. The murder of Osiris by Set, and the resulting struggle for power, won by Horus, provided a powerful narrative linking the ancient Egyptian ideology of kingship with the creation of the cosmos.

Throwing is a physical action that consists of mechanically accelerating a projectile and then releasing it into a ballistic trajectory, usually with the aim of impacting a distant target. Throwing typically refers to hand-throwing by animals with prehensile forelimbs, in which the projectile is grasped in a hand and the proximal limb segments move through compounded kinematic chains to impart a mechanically advantaged swinging motion. For other animals, the definition of throwing is somewhat unclear, as other actions such as spitting or spraying may or may not be included.

Primates are the most proliferative throwers in the animal kingdom, and they typically throw feces as a form of agonistic behavior. Of all primates, humans are by far the most capable throwers, able to throw a large variety of projectiles with great force and accuracy. Throughout human evolution, humans (especially Homo sapiens) have used hand-thrown projectiles for hunting and in warfare — first through rock-throwing, then refined weapon-throwing (e.g. spear, axe or dart), and into modern day with payload-carrying devices such as hand grenades, flashbangs and tear gas canisters.

A spittoon (or spitoon) is a receptacle made for spitting into, especially by users of chewing and dipping tobacco. It is also known as a cuspidor (which is the Portuguese word for "spitter" or "spittoon", from the verb "cuspir" meaning "to spit"), although that term is also used for a type of spitting sink used in dentistry.

A surgical mask, also known by other names such as a medical face mask or procedure mask, is a personal protective equipment used by healthcare professionals that serves as a mechanical barrier that interferes with direct airflow in and out of respiratory orifices (i.e. nose and mouth). This helps reduce airborne transmission of pathogens and other aerosolized contaminants between the wearer and nearby people via respiratory droplets ejected when sneezing, coughing, forceful expiration or unintentionally spitting when talking, etc. Surgical masks may be labeled as surgical, isolation, dental or medical procedure masks.

Although the material of which surgical masks are made will filter out some viruses and bacteria by trapping the aerosol suspended in breathed air, they only provide partial protection from airborne diseases because of the typically loose fit between the mask edges and the wearer's face. Surgical masks are distinct from filtering respirators, such as those made to the American N95 standard, which are more airtight and purposefully designed to protect against finer airborne particles.

Chewing tobacco is a type of smokeless tobacco product that is placed between the cheek and lower gum to draw out its flavor. It consists of coarsely chopped aged tobacco that is flavored and often sweetened; it is not ground fine like dipping tobacco. Unwanted juices are spat while chewing.

Chewing tobacco is a source of nicotine and therefore highly addictive. Quitting chewing tobacco use is as challenging as smoking cessation.
