Circulatory System

Carbon dioxide- Breathing

Lactic Acid- Excersize burns off lactic acid. ( The reason your muscles cramp after you work out is due to a build up of lactic acid, it may be painful, but if you run more or stretch it gets rid of the spare lactic acid.

People who do a lot of exercise can have larger hearts because the heart muscle like any other muscle grows the more it is used. An enlarged heart can also be a sign that there is some other problem with the circulatory system, which means that the heart is having to work harder than normal to compensate, and the heart muscle will grow for the same reasons as when it works harder in exercise.

The cells of the heart are supplied with blood through the hearts own artery. The artery that supplies the heart blood is known as the coronary artery.

This system contains the heart, arteries, veins and capillaries.

Firstly Are u sensible enough to understand the answer of this question?

If yes then open ur Biology book and go through the respective chapters.

Then use your common sense to connect the dots.

ta dah! There you go now you the answer to your question.

p.s. If u are not in the possession of a biology book, jst use your younger siblings, better yet ask them this question. Surely they'll know d answer.

His major original contribution of great significance was his discovery of the blood's circulatory system, which was discovered again by modern science after a lapse of three centuries. He was the first to correctly describe the constitution of the lungs and gave a description of the bronchi and the interaction between the human body's vessels for air and blood. Also, he elaborated the function of the coronary arteries as feeding the cardiac muscle. Hope this helps.

The atria are a part of your heart which is in the circulatory system

The jet pump should have a 3/8" plug at the top of the pump,, where the water comes in from the well. Remove plug, and fill that port up as much as you can, turn pump on,,and keep filling with clean water,,[any dirt that gets caught in side the venturi it will not archive priming],,once the port is full the motor will start singing a different tune,, you will know when it starts pulling water because you will hear the load on the motor,,and water will start to come gushing out the port,,quickly install the 3/8 plug, [make sure the plug has pipe dope on it before you install it] at that time it should start pulling water,and once the pump reaches 50 or 60 lbs. The pump will shut off. If it does not hold the prime the 1st time repeat by removing the 3/8" plug again . It may take a few times before the pump holds its prime.

The "dub" sound in the heartbeat is produced by the closure of the semilunar valves (the aortic and pulmonary valves) at the end of ventricular contraction (systole). This sound follows the "lub," which is caused by the closure of the atrioventricular valves (mitral and tricuspid). The "dub" signifies the beginning of ventricular relaxation (diastole) as the blood flow shifts from the ventricles to the arteries.

By the vagus nerve.

The respiratory system works directly with the circulatory system when to oxygenate blood.

To provide a way for immune cells to reach targets ie infection

To allow the transfer of oxygen and carbon dioxide between cells in the body and the atmosphere

To allow transport of hormones and nutrients from site of production/absorption to the rest of the body (which allows differentation of cells so they all don't have to be making the same hormones)

-var,const,uses declaration part

could start with uses in case of a declaration for a libr ex. (uses crt)

var,const refers to those used in the main probram

-functions,procedures declaration part

declaration of the function/procedure + content ex.

(function one(x:integer):integer;

var y:integer;

begin

......

one=....(integer expresion for return value);

......

end;)

the procedures don't have any return value (:integer)

-main program

Turtles have a three-chambered heart, consisting of two atria and one ventricle, which allows for some mixing of oxygenated and deoxygenated blood. In contrast, humans have a four-chambered heart that completely separates oxygen-rich blood from oxygen-poor blood, making their circulatory system more efficient. Turtles also have a lower metabolic rate and can tolerate longer periods without oxygen, adapting their circulatory function to their aquatic lifestyle. Overall, the differences reflect the distinct physiological needs and environments of each species.

yes it has

the circulatory system transport all the blood to the whole body.
