Circulatory System

This is to facilitate the exchange of materials between foetus and placenta.

The Blood vessels and arteries and the heart.

Also common is the cardiovascular system.

I may be guessing here but I am thinking with an increase in stroke volume you body is getting more volume per beat ... therefore it compensates by lowering the heart rate. if your pump is more efficient then you body doesn't need your heart to pump as often. That's the only rationale i can think would cause it!

The primary goal of the urinary system is the elimination of waste from the body processes. If these wastes are not removed, they may become toxic to the system. The circulatory system deposits the waste for the urinary system to remove.

When an individual suddenly collapses, the possibility of ventricular fibrillation should be considered immediately.

The blood plasma is the liquid part of the blood. It is the part of the circulatory system made up primarily of water, nutrients, and wastes.

Because the job of the white blood cells is to fight infection and diseases - in much the same way as a country sends its army to fight off invaders.

Smoking, lack of exercise, lack of attention to Asthma, and exposure to irritants such as dust can all affect the performance of the respiratory and circulatory systems.

blood pressure and your heart would be healthy

Unicellular: Exchanges occur directly with enviroment Multicellular: Diffusion is not possible unless diffusion across body surface. Transporting substances over long distance in animals.

Outputs would stop.

because they have a long tissues that the blood flows

In the circulatory system, when the body aquires oxygen diffusion takes place. In the capillaries, oxygen diffuses into the bloodstream, while carbon dioxide diffuses out. Without diffusion could not aquire for oxygen to got to the heart and circulate through out the body.

Yes, the circulatory system is constantly carrying oxygen to all the cells of the body. If it could no longer do so, either due to the heart no longer pumping efficiently or due to excessive blood loss, the cells of the body, particularly the brain, would start dying within minutes. (The amount of time cells can live after their oxygen supply is cut off can be extended somewhat by reducing the temperature of the cells, thereby slowing their metabolism.)

1. Blood carrying carbon dyoxide from all over your body enters the Right Atrium.
2. Blood enters the Right Ventricle.
3. Blood from the Right ventricle goes to the lungs.
4. Blood loses Carbon Dyoxide and receives oxygen from the lungs.
5. Blood leaves the lungs and enters the Left Atrium.
6. Blood leaves there and enters the Left Ventricle.
7. Blood goes through the Aorta artery and caradic artery, then goes to all over your body.

The most common ailments are: varicose veins, arteriosclerosis, atherosclerosis, angina, anemia, thrombosis, blood clots, strokes, aneurysms, etc.

Also there is Coronary Artery Disease (CAD) which is the most common and is the leading cause of death in the US. It is also called "hardening of the arteries", arteriosclerosis, atherosclerosis, can lead to angina pectoris and heart attack. The biggest contributor to its development is major depression, but also cigarette smoking, obesity, and lack of exercise also are known to be contributors.

Human blood has red color when oxygenated which is mainly because of red blood cells. Its color changes to purple when present in oxygen deprived circumstances. To restore the color the blood has to be placed in oxygen rich environment.

the role of the teeth is so that you can smash it to smaller pieces so that the stomach wont have to take longer than 10 hours to digest the food, and also so you would not choke

The cell membrane is the part of the cell that controls what enters and leaves the cell. It allows nutrients to come in and wastes to move out.

Even during gestation, fetal kittens have a closed circulatory system.

Blood group A can donate and receive blood from blood group A.

Blood group B can donate and receive blood from blood group B.

Blood group AB can donate only to blood group AB and receive from any other blood group (they are universal recipent)

Blood group O can donate to any other blood group ( they are universal donor) and can receive from only blood group O.

The Circulatory system is a busy system because it can never stop. Your circulatory system is what pumps your blood and gives your cells food water and oxygen and takes waste away from your cells. If your circulatory system ever stopped then you would die.
