Circulatory System

The Heart, The Blood, and the Blood Vessels

Both of the systems are responsible for transporting nutrients to the difference parts of the organism. They differ in what they transfer and how. Plants use gravity and the cohesion of water to transfer nutrients. An animals circulatory system, on the other hand, uses pressure that is built up by the heart muscle to push the blood to all parts of the body. This is why people with low blood pressure often have cold hands and feet.

It runs throughout your body. The main part is the heart, which pumps blood through arteries that are in all parts of the body. Blood also goes to capillaries which are attached to organs and pass blood from the artery to the vein. Blood in these contain oxygen which is being brought to organs, and parts of the body. When they do not have oxygen anymore, they return to the heart in veins.
It is all over the whole body! The heart is only the pumping station!

Blood is pumped by the heart. Blood leaves the heart via the arteries and returns to the heart via the veins. Blood returning to the heart goes to the lungs where it is oxygenated then pumped around the arteries

Veins

^ wow, no. not at all.

The heart pumps the blood to the entire body.

If you mean carry , then it would be the circulatory system.

Respiration.

Lymphadenitis

In the circulatory system, the heart rate increases and blood flow increses to the exercising muscles, and lessens to the other parts of the body. Your respiratory system doesn't change except for the amount of air flow. By Zahra Naiem

The order of oxygen flow begin in the right atrium, to the right ventricle. Into the pulmonary artery to the lungs returning via the pulmonary veins to the left atrium. From the left atrium to the left ventricle to the aota then into the body.

The circulatory system, now generally referred to as the cardiovascular system, can be affected by a variety of diseases that can be broadly classified as infectious, inflammatory, degenerative or cancerous.

An example of an infectious disease of the cardiovascular system would be bacterial endocarditis. This is when a bacteria become attached to one or more valves of the heart and set up a localized infection.

An example of an inflammatory disease of the cardiovascular system would be athlerosclerosis. This is when inflammatory mediators cause the lining of the blood vessels to become "sticky", which allows cholesterol molecules to be deposited in the walls of the vessels. The cholesterol hardens the arteries, making them more likely to rupture or become blocked.

An example of a degenerative disease of the cardiovascular system would be endocardiosis. This is a chronic disease in which the valves of the heart slowly degenerate and become less competent at closing the openings between the heart chambers. Eventually this can lead to congestive heart failure if it becomes bad enough.

An example of a cancerous disease of the cardiovascular system would be hemangiosarcoma. This is a neoplasia that arises from the lining of the blood vessels and branches off from normal vessels to create very fragile pseudo-vessels. Unfortunately, one of the more common symptoms of this cancer is sudden death; thankfully in humans this cancer is relatively rare.

The heart is responsible for pumping blood.

The main organ of the circulatory system is the heart. Some consider the blood an organ as well, since it is basically liquid tissue. The third and final component of the circulatory system is the blood vessels - veins and arteries - that carry the blood throughout the body.

Systemic circulation begins and ends at the left side of the heart, in the left atrium and left ventricle.

Cytotoxic T cells and NK cells (natural killers)

The real function and purpose of the Circulatory system is to keep us alive (of course working in conjunction with the other systems of the body). The Circulatory system carries food and oxygen to all the cells of the body and then in response to that removes all waste products.

Generally we say that we inhale only oxygen and exhale only CO2. But actually it is not like that.

We hale air which has every gas in it.

But the greater % we take in is O2 and greater % we leave out is Co2.Other gases are insignificant in the process of respiration.at first air enter into the lungs specifically to say in the alvioli . then through the alveolar wall O2 enters into the blood by diffusion and similarly CO2 enters into the lungs from blood . thus this system works .

The main organs of the respiratory system are the lungs. The main organs of the circulatory system are the heart and blood vessels.

if you are dehydrated, the kidneys hold on to as much fluid as they can, which results in a decreased urine output.

Because of the decreased urine output, you are not excreting enough salt and water, which then causes increased volume fluid.

This increased water retension increases your blood pressure

The cardiovascular system consists of the heart, blood, and blood vessels, like veins and arteries. There is a related system to the cardiovascular system called the lymphatic system which moves lymphatic fluid through the spleen, lymphatic tissues, and lymphatic vessels. Some sources consider these two to be one system, the circulatory system, because they both "circulate" fluids in the body.

Purkinje fibers are located in the endocardium.

Endocardium: This is the inner layer of the heart that consists of epithelium and underlying connective tissue. The endocardium also contains bloods vessels and Purkinje fibers. The endocardium lines all of the heart chambers and covers structures, such as heart valves, that project into them. This inner lining is also continuous with the (endothelium) of the blood vessels attached to the heart and throughout the cardiovascular system.

The respiratory and circulatory system connect in the lungs. At the alveoli, the air sacs are wrapped closely by capillaries to facilitate gas exchange.

What is the difference between the digestive system of a camel and the digestive system of man?

Right so let's break the first task down; what is happening to her circulatory systemfirst of all.

When you exercise, or play football in this case, you are working your muscles and certain places in the body. When this happens, your muscles respire (burn the FOOD to produce ENERGY) more faster than they would normally, so the demand for OXYGEN and GLUCOSE is increased.

Because the muscles are performing cellular RESPIRATION quicker than the norm, they need oxygen and glucose to reach them faster (glucose and oxygen are the components for cellular respiration), and also they need to get rid of their C02 (products of cellular respiration are CARBON DIOXIDE and WATER) so the HEART is now pumping blood around the body at a faster rate in order to provide these cells with what they need. To summarize, the circulatory system has to work harder and faster during exercise to provide the cells at work with glucose and oxygen and to get rid of the waste carbon dioxide.

Right now the next part of the task asks what is happening to her breathing system (aka respiratory system).

This relates to the explanation I gave earlier; the requirement for oxygen is increased so now the respiratory system (in particular the LUNGS) have to work harder and faster to take in more oxygen and to exhale more C02, thus you begin to breathe faster. To summarize, oxygen is inhaled quicker and carbon dioxide is exhaled quicker, therefore the rate of DIFFUSION is increased.

Oh and for the diagrams you could draw a picture of a girl playing football, then next to that have a picture of her lungs and heart (including the arteries/veins) and show how they are working harder during exercise.

Lung cancer reduces lung function (just before it kills you). The reduced lung function means there would be less gas exchange taking place, which means less oxygen getting to the body.

nicotine is a dangerous "drug" that damages the respiratory system , specifically the lungs . So, If a person does not smokes , and does not inhale "secondhand smoke" , his/her respiratory system will be healthy...
