Circulatory System

the digestive system breaks down what we eat the the circulatory system delivers the nutrients to cells for metabolism

thrombosis... rheumatic heart disease... congenital heart disease... atherosclerosis... arteriosclerosis... sepsis.... hope that helps... :D

Elongated superficial dilated veins, are called Varicose veins.

The circulatory system is comprised of the cardiovascular system and the lymphatic system. It is the lymphatic system and its network of lymphatic capillaries, lymph nodes, thymus gland. and the spleen that make up our immune system. It protects the body from pathogens; bacteria, viruses, and fungi.

Oxygen and carbon dioxide are exchanged by way of the circulatory system. Cells use oxygen for energy and produce carbon dioxide as a waste. Capillaries are where this exchange occurs. Veins carry this product back to the heart. This blood goes to the lungs were you blow off the carbon dioxide and take in oxygen. So the circulatory system and lungs work together to exchange gases.

Yes. Blood is made up of 45% formed elements: 1. Red Blood Cells, 2. White blood cells, and 3. Platelets. Plus 55% plasma which is mostly liquid with some plasma proteins and clotting factors.

Leukemia is the name of the disease described.

The human heart is positioned under the left lung, in the center, slightly to the left in the chest cavity.

That depends on the type of heart disease. Some times the arteries are affected. Some times the venous system is affected. Some times both the systems are affected.

• Pulmonary circuit ,, Systemic circuit ,, Portal circuit ,, Venal circuit ,, and i dont know the other one, heeeehhe :T

It depends which disease it is because there are many different diseases in the Circulatory System.

The cardiovascular system pumps blood throughout the body.
The Nervous System of course.

YES

the heart is the main circulatory organ of the frog

erythropoiesis is triggered by low oxygen levels.

You can not name the technology, that does not harm your circulatory system. The technology makes your life easier. The easier life tend to damage your circulatory system. I have never seen the heart attack in a person, who is working himself, in the agriculture farms. Most of the population around me work in farms. These people does not have any much subcutaneous fat in body, although they consume lot of food, as compared to you. People with sedentary life style only die of heart attack. It is the gift of nature that people with sedentary life style live longer than expected.

The circulatory and respiratory systems work together to get oxygen to cells. Oxygen transfers from the respiratory to the circulatory system at the capillaries surrounding the alveoli.

There is no way except exercise to get more blood to the knees. You heart has to pump blood to every part of the body and since the legs are lower, you already get a lot.

The 'lub' is the S1 sound. It occurs due to normal closure of the mitral and tricuspid (atrioventricular) valves. With these valves closed, systole commences and blood is actively squeezed from the ventricles. The second sound is the 'dub' or S2 sound. It occurs as the aortic (to LV) and pulmonary (to RV) valves close to prevent backflow from the blood ejected from the ventricles and marks the beginning of diastole (or filling) of the heart.

I'm not sure I understand the question- if you want a list of respiratory diseases for an assignment for your science class, here are a few: Asthma Pulmonary Disease (something smokers get) Croup (something children get) Common cold bronchitis Hope that helps! Heather (an MD from Canada)

The blood from the body tissues arrives at the heart in vessels called the inferior and superior Vena Cavas. It enters the right atrium of the heart and is pumped passed the tricuspid valve into the right ventricle. Then a second, delayed contraction, pushes the blood through another valve, the pulmonary semilunar valve into the pulmonary trunk. From here the blood moves through the left and right pulmonary arteries and enters the left and right lungs where gas exchange takes place. Carbon dioxide is dropped off and oxygen is picked up by the hemoglobin of the blood by a process known as diffusion. Then oxygenated blood moves through the pulmonary veins to the heart and enter into the left atrium. This completes the pulmonary circuit of the cardiovascular system.

The respiratory and circulatory systems interact within the alveoli in a simultaneous manner. When you breathe in the oxygen in diffused in the alveoli which is then carried by the blood to the heart and pumped to the rest of the body.

the circulatory system helps other systems function because it circulates blood to the other systems in your body and that helps the other systems function because the other systems have to pass that through that system
