The blood transports oxygen (as oxyhaemoglobin) to the cells of the body, it contains the cells that are a part of our immune system (white blood cells).
It transports away from cells CO2 and urea, and it carries chemical signals such as hormones.
That's the potted version - try Wikipedia for more.
It comes from an artery. Arteries carry OXYGENATED blood away from heart. This oxygenated blood is bright red. The Arterial system is on the high pressure side of the heart. The pressure changes as the heart contracts and then expands and refills (a heartbeat). When an artery is punctured the blood will spurt with every heartbeat.
The circulatory system.
The blood transport system in the body is designed to remove waste from cells and to deliver oxygen to cells. This system is controlled by the brain and driven by the heart.
main organs of the circulatory system are the heart and veins. their purpose is to circulate blood in the body.
if the spine is completely severed, the electrical signals sent from the brain through the nervous system cannot reach anything below the point where the sinal cord was severed
The purpose of the excretory system is to eliminate waste and excess substances from the body, such as urea, salts, and water, to maintain proper balance of these substances in the blood and tissues. It also helps regulate blood pressure and pH levels in the body.
The main function of the systemic circulatory system is to carry oxygenated blood away from the heart and into the body. It then returns deoxygenated blood back to the heart.
The purpose of regulating the blood collection system is to ensure the safety and quality of blood products collected from donors. Regulations help prevent the transmission of infectious diseases, maintain accurate labeling and tracking of blood products, and ensure that collection practices adhere to high standards to protect both donors and recipients.
He arose from the blood that dripped from Medusa's severed head.
The purpose of the blood collection and distribution system is to help ensure an adequate supply of blood for accident victims, people needing surgery, and people suffering from certain diseases, as well as for medical research.
A blood type converter is used to determine the compatibility of blood types for transfusions. It works by converting blood types from one system (such as ABO) to another system (such as Rh factor) to ensure safe and successful transfusions.
A severed head can remain alive for a very short period after being detached from the body, typically only a few minutes. This is due to the brain's reliance on blood supply for oxygen, which is cut off when the head is severed. Some anecdotal accounts suggest that reflexive movements or facial expressions can occur for a brief time, but these are not signs of consciousness. Ultimately, without a functioning circulatory system, brain activity ceases quickly.
