Because of a thing call osmosis. If you place a permeable (one which will allow the slow leackage of water but not solids) membrane between two containers and fill one with pure water and the other with salty water so that they were both up to the same level. Then with time the salty container would fill up more at the expense of the fresh water side. Nature likes equal concentrations of saltyness and as the salt can not move acriss the membrane, fresh water leaks form the fresh water side to try and make the salty side more dilute.
Blood is slightly saline (salty) and in balance with the saltiness of the tissues and cells in the body. If you were to dilute the blood by injecting pure water, then the cells would start to to fill up with more water (because of osmosis) and they would burst, causing alot of damage to the body. That is why intravenous water is a slaine solution made to be the same osmotic salinity as blood.
Rabbits have a closed circulatory system, meaning that their blood flows through a series of vessels and the heart pumps it continuously around the body. This system allows for efficient transport of oxygen, nutrients, and waste products throughout the rabbit's body.
Bacteria do not have a circulatory system like humans. Instead, they rely on diffusion to transport nutrients and waste products across their cell membranes. This process is efficient for small, single-celled organisms without complex body structures.
The respiratory system is most directly involved in the transport of oxygen in humans. Oxygen enters the body through the lungs during inhalation and is then transported by the circulatory system via red blood cells to tissues and organs where it is needed for cellular respiration.
The perch has a single circulatory system that consists of a two-chambered heart and blood vessels, while humans have a double circulatory system with a four-chambered heart. In the perch, blood flows from the heart to the gills for oxygenation and then to the body tissues, while in humans, blood circulates from the heart to the lungs for oxygenation and then back to the heart before being pumped to the rest of the body.
In humans, the heart, lungs, liver, and kidneys are part of the larger organ system known as the circulatory system, respiratory system, digestive system, and urinary system respectively. These systems work together to maintain the body's functions and overall health.
Both are close circulatory system.
mammals have closed circulatory system and further double circulatory system.
circulatory system
Their circulartion system is very similar to humans (closed circulatory system)
Humans have a closed circulatory system, in which blood is pumped by the heart through dedicated vessels, where it stays contained, as opposed to an open circulatory system (usually found in invertebrates) where blood is pumped out of the heart and vessels.
YES.
The circulatory system is important to humans because the main components are the heart, the blood, and blood vessels.
each and every moment.
yes areteries and veins
Humans have the most advanced blood and fluid circulatory system.
Humans are mammals so yes you idiot!
The purpose is basically the same as a humans
