Circulatory System

When we breathe from our mouth or nose, the air, which contains oxygen, nitrogen, and other types of gases, pass the larynx, where the vocal cords locate. When oxygen reaches the chest cavity, the bronchi divides itself so that the bronchi can direct the oxygen to the lungs. When the bronchial tubes direct the oxygen and air into the alveoli, it then reaches your bloodstream. When the respiratory system finishes its course, the diaphragm, which locates under the chest cavity, eliminates carbon dioxide. This explains why we have to exhale after we inhale.

The main purpose of the respiratory system is to supply oxygen for the blood and other organs such as the brain.

The path of blood from the heart to the kidneys is first from the abdominal aorta the blood enters the kidney through the renal artery. Then the renal artery divides into a number of segmental arteries. The segments arteries divide into lobar artery. The lobar arteries divide into inter-lobar arteries that travel between the renal pyramids. The inter-lobar arteries branch into arcuate arteries that travel between the cortex and medulla. From the arcuate arteries the blood is carried into the nephrons. In the nephron the blood enters through the afferent arteriole and into the glomerulus. The blood leaves the glomerulus by the way of the efferent arteriole, which the blood is carried to the peritubular capillaries, and finally to the vasa recta. When the blood reached the vasa recta that means that it had travelled through the whole nephron.

The blood travels back to the heart through the veins. First through the interlobular vain, then through the arcuate vein, then through the interlobar vain, then through the segmental vain, and finally exists the kidney by the way of renal vein, and into the inferior vena cava.

The circulatory system helps by pumping oxygen rich blood to the rest of the body (from the heart), being a source of travel for the blood so it can reach all parts of the body (blood vessels), removing carbon dioxide and other wastes from the cells in the body via the blood, and providing the various cells in the body with oxygen so that they can carry out various cell processes, such as cellular respiration, which keep a living organism alive. Without oxygen, and a means to be rid of carbon dioxide and wastes, humans and other organisms would not be able to survive.

The circulatory system play a key role in providing the body with the oxygen needed by cells. The circulating blood carries the oxygen replenished red cells through the arteries to all parts of the body.

This word can be broken down into two parts that will reveal the answer to your question. Myo is the medical term for muscle and cardio is the medical term for heart. Therefore, your answer would be the muscle that is the heart.

In the lungs,Blood is exchanged adn sent to different parts of the body.

• Yup. Here are some of the problems that can happen:
• Pulmonary edema (intensive-care patients on breathing machines at 30 hours or more exposure)
• Decreases in the rate of gas exchange across the alveoli (intensive-care patients on breathing machines at 30 hours of exposure)
• Chest pains that were worse during deep breathing (volunteers with 24 hours of exposure)
• Decrease in the total volume of exchangeable air in the lung (vital capacity) by 17 percent (volunteers with 24 hours of exposure)
• Local areas of collapsed alveoli when plugged by mucus, a condition called atelectasis (patients, volunteers). The oxygen entrapped in the plugged alveolus gets absorbed into the blood, no gas is left to keep the plugged alveolus inflated and it collapses. Mucus plugs happen normally but are cleared by coughing. Also, if alveoli become plugged during air breathing, the nitrogen entrapped in the alveoli keeps them inflated.
• blindness caused by inadequate development of the capillaries in the lens and retina of the eye (premature infants). Reducing the oxygen to 40 percent can prevent this blindness.

A Closed Circulatory system-Is a blood circulation system in which blood moves through the body in closed vessels.

In the closed circulatory system, the blood is confined to vessels. The heart pumps blood to vessels through smaller vessels which go to the organs. This system has a more efficient way of transporting blood then an open circulatory system.

Some animals that have this systems include earthworms, squids, octopus, and all vertebrates, like humans.

smoking: lung cancer, caused you to cough grossly and choke

smog: it will make you sick and it could give you cancer

pollen: allergies, sneezing, coughing, ichy eyes and nose, runny nose

The cardiovascular system transports liquid and nutrients throughout the body.

the three blood vessels are the Veins capillaries Arteries the arteries.

deoxygenated blood in the foot diffuses from tissues into capillaries--> venules--> veins

the veins carry the deoxygenated blood back to the heart against gravity by a series of valves

The deoxygenated blood enters the posterior venacava--> right atrium--> atrioventricular valve--> right ventricle--> pulmonary valve--> pulmonary artery--> capillaries in the lungs

After obtaining oxygen, the blood travels back to the heart in the pulmonary vein--> left atrium--> atrioventricular valve--> left ventrical--> aortic valve--> aorta

The aorta pumps the oxygenated blood back to the body through a series of arteries--> arterioles--> capillaries--> back into the tissue cells of the foot

Leukemia is a type of cancer that begins in the bone marrow and causes an abnormal high amount of white blood cells. The way in which leukemia affects you includes the fact that you will bruise easily and bleed excessively. You will also be more prone to infection, may feel sick and lose weight.

A system that can exchange matter with its surroundings

The major organ of the circulatory system is the heart. The three parts that are involved with the circulatory system are the blood, the heart, and the vessels.

There are various factors that may put a person at risk for developing cardiovascular diseases. A common one is smoking (clogs the arteries, can lead to atherosclerosis). Poor lifestyle, that is, lack of exercise and poor dietary or nutritional intake (high fat, high sodium). Stress is also another factor. Frequent alcohol drinking is also another risk factor. Generally, being male makes you more prone to developing cardiovascular diseases, due to males having a more unhealthy lifestyle.

At first I thought you were referring to the human circulatory system!

The Walker circulation or Thermohaline circulation is where cold, dense, salty water sinks in the arctic and Antarctic. This water flows along the sea floor, moving towards the poles. Warmer water from the equator then replaces this.

In terms of global warming, more ice is melting in the summer. Icebergs don't contain as much salt, and do they dilute the oceans at both poles. This reduces the density of the water, meaning it doesn't sink as efficiently. This in turn can slow or even stop ocean flows such as The Gulf Stream. the circulation is very significant- research it online for more info.

When exercising you Tial Volume increase because your breathing at a faster rate and your muscles are using up the oxygen at a quicker rate hense a need for more oxygen hense you body increasing the Tidal Volume to allow more oxygen to be consumed and meet the muscles oxygen demands.

Yes, in a major way. Half of your heart (the right side) is devoted to taking the blood collected from your body and pumping it to the lungs where it releases its carbon dioxide and picks up fresh oxygen. The other half of your heart (the left side) is devoted to collecting this blood from the lungs and pumping it out to the body.

The brain can survive without oxygen for about 3 minutes before it is permanently damaged. After 3 minutes there is likely to be severe brain damge which usually leads to a coma. If you survive the coma you will probably have very limited brain function i.e. not being able to walk or talk. After 10 minutes, (without special measures such as freezing) the brain will most likely be dead.

The circulatory system transports blood throughout your body passing through your heart where it is pumped throught the rest of your body to give energy and oxygen to cells and muscles. That's why you can see the veins in your wrist. blood is being pumped to every part of your body right now.

Circulating Nurses are responsible for the safety of a person undergoing invasive and minimally invasive surgical procedures. The Registered Nurse is the professional in the role of circulator. The RN interviews the patient, establishes a rapport with the patient and attends the patient through the surgical procedure. Some tasks: assisting with induction of anesthesia, proper patient positioning, prepping the surgical site, maintaining sterility in the OR, monitoring the surgical procedure for continuity of sterility, patient safety and completing the legal medical record of the procedure. At the completion of the procedure, the RN accompanies the patient to the Post Anesthesia Care Unit and hands care of the client to the Nurse in that department.
