In all likelihood you would die as calcium is essential for both muscle contraction and nervous system communication.
Although the heart pumps blood with the ions of calcium necessary for the contraction and the brain sends the electrical signals for contraction the muscular systems mainly needs calcium ions for contraction and that the proteins that make up its cell work properly (myosin and actin and other filaments in the sarcomeres.
Calcium is important for your health because it contains an element that helps to strengthen your bones, fingernails and teeth and makes you less prone to getting chipped teeth and broken bones.
Lead intoxication affects many systems of the body including the cardiovascular, renal, and reproductive systems. Its most detrimental effects occur in the nervous system, where lead blocks the receptor know as N-methyl-D-aspartate, an effective receptor involved in the maturation of brain plasticity.The toxicity of lead plays a major role in the communication between astrocytes and endothelial cells.By disrupting the blood-brain barrier, it causes encephalopathy and edema that primarily affects the cerebellum.Intracellularly, lead replaces calcium as a second messenger, binding with calmodulin more readily than calcium, resulting in an alteration in protein conformation.Intracellularly, lead replaces calcium as a second messenger, binding with calmodulin more readily than calcium, resulting in an alteration in protein conformation.
There's more than one chemical that causes contraction. The neurotransmitter (usually acetylcholine) is released from the nerve and excites the muscle. There is a change in calcium, sodium and potassium ion concentrations. ATP is used. All of these work together to produce a muscle contraction.
Yes, temp. regulation is a function of the Cardiovascular system but also the Integumentary system. The blood distributes heat created by muscle contraction to the rest of the body. Blood vessels in the skin dilate when body temperature rises and constrict when heat needs to be conserved. In this way, the integumentary system plays a key role in regulating body temperature.
Calcium is an important part of our diets. It's found in dairy products, sardines, bread, watercress and cabbage. It is required for healthy bone structure as well as nerve function and muscle contraction. If calcium is not obtained in a diet, rickets and soft bones are the deficiency diseases. This is why calcium is so important.
Extrinsic regulation
The US legal system plays a crucial role in business regulation by setting the rules and standards that businesses must follow to operate legally. It provides a framework for resolving disputes, enforcing contracts, and ensuring fair competition. The legal system also helps protect consumers, employees, and the environment by holding businesses accountable for their actions.
