Circulatory System

The Vein does not bring blood to the Heart.

blood first enters the heart through the right atrium.

The liver, aside from producing bile, is where most of the metabolic processesof the organism take place. It synthethizes a great ammount of proteins such as albumin and coagulating factors, it also metabolizes nitrogenated compounds such as urea and creatinin. Most drugs also get modified or neutralized in the liver.

So, if the liver wasn't there, firstly, the loss of albumin would produce from localized edema to anasarca; loss of coagulation factors would hinder coagulation and injuries would take a lot to heal, and you'd bleed a lot in the process; accumulation of nitrogenated compounds is called azoemia, and it can produce severe brain damage: haepatic encephalopathy. Drugs would remain in your blood stream a lot longer and can be toxic even in normal doses. Indirect bilirrubin would accumulate as well, inducing jaundice (yellow coloration of skin and mucuses).

If your heartbeat speeds up slightly then this is respiratory sinus arrhythmia - this is normal, healthy heart-rate variation and is nothing to worry about. It is an indicator of health.

The circulatory helps medicenes work because it helps transport blood throught the whole body.SO when the medicene get in your blood it flows through and then gets to the lymphatic system.Which cleans out all the bad things in our body and where white blood cells kill germs and etc.

The muscular system uses the bones for their action. Without bones muscles would be useless at distance. Bones act like lever arms to increase the force produced by muscles. The digestive system gives nutrients to the muscles.

The human circulatory system moves blood through the body similar to the hydraulic system which moves liquid water.

You have lesser circulation or the pulmonary circulation. Blood goes to lungs in this system from the right side of heart. You have greater circulation or the systemic circulation. Blood goes to all over the rest of body through this circulation. The amount of blood that flows is same in both the systems. You have about 25/15 mm of Hg pressure in pulmonary circulation. You have about 120/80 mm of Hg pressure in systemic circulation.

Your question is not quite clear, but if you are asking "does the circulatory system help maintain body temperature?" then I would the answer is yes. It moves blood throughout the body which regulates the body temperature. Doing so also supplies supplies oxygen and nutrients for the cells in your body.

The circulatory system!

The small oval structures that cluster along the lymph vessels are called lymph nodes. The nodes that can be palpated are the cervical, axillary and inguinal nodes.

The aorta artery which carries blood to the rest of your body is located on the top right ventricle of the heart.

The fluids of the lymph system are carried into the circulatory system because they contain plasma proteins. The vessels of the lymphatic system provide a way for interstitial fluid to move through the circulatory system.

If there was no muscle tissue, the cell would build up different body air and eventually would not be used to it and the cell would be gone and die.

The capillaries are there at tissue level. They are very tiny. The diameter of the capillary is about 8 micro meter only. They are present in very large number. The total cross sectional area is estimated to be 2400 square cm. They are there every where in your body. Nobody probably know about the three dimensional orientation of the capillaries.

A double circulatory system is also known as a double-loop circulatory system. This system contains two distinct pathways for blood to flow through the body. In most creatures, this consists of the loop between the lungs and heart, and the loop between the heart and body.

The sinoatrial (SA) node of the heart serves as its pacemaker, and receives nerve input from the nervous system in order to initiate the "pumping" activity that controls the circulatory system.

In addition, muscles of blood vessels can expand and contract from signals from the autonomic (sympathetic and parasympathetic) nervous system in order to control blood pressure.

The superior vena cava and inferior vena cava are the two vessels that return oxygen-poor blood to the heart. Both empty into the heart's right atrium.

Annelids have a closed circulatory system.

HIV infects the circulatory system (is carried in the blood and other bodily fluids). It weakens the immune system when the person develops full blown AIDS (as a result of contracting the HIV virus).
