Where is urea removed from after it has passed through the blood?

The Kidneys, where the blood/urea thing takes place.


What is a system that supplies oxygen to the cells and removes carbon dioxide to the blood?

The respiratory system is responsible for supplying oxygen to the cells through breathing in, and removing carbon dioxide from the blood through breathing out. This process occurs in the lungs where gas exchange takes place between the air and blood in the pulmonary capillaries.


Where in the eye does the refraction take place?

light passes trough the cornea then through the pupil and opening created by the iris, then the light passes through the lens, then travels along the aqueous humerous then arrives at the retina; the retina changes teh light into electrical impulses and send them trough the optic nerve then to the brain where an image is perceived. HOPE THAT HELPS


When the acidic level of human blood increases how is homeostasis maintained?

The body has buffering systems in place, such as bicarbonate ions in the blood, to help regulate pH levels. The kidneys also play a role in maintaining pH balance by excreting excess acids or bases. Through these mechanisms, the body can maintain homeostasis despite changes in acidity levels.


The place where nutrients enters the blood?

Nutrients enter the blood primarily through the small intestine. After food is broken down in the stomach, nutrients are absorbed through the lining of the small intestine and into the bloodstream. From there, the blood carries these nutrients to different parts of the body where they are used for energy and growth.

Where does the blood move next after the veins?

after exchange takes place between the veins and the arteries at the capillaries, blood travels through venules to larger veins which all hook up the superior and inferior vena cava, which drain into the R atrium of the heart.

What is the difference between a thrombus and an embolus?

Thrombus: A fibrinous clot that forms in and obstructs a blood vessel, or that forms in one of the chambers of the heart. (It stays in one place) Embolus: A mass, such as an air bubble, a detached blood clot, or a foreign body, that travels through the bloodstream and lodges so as to obstruct or occlude a blood vessel


What changes in the composition of the blood take place in the lungs?

Oxygen levels go up while CO2 levels go down. In the lungs, oxygen is absorbed into the blood while carbon dioxide is eliminated through exhaling.

What is the final destination of the air breathed in?

I depends. There are two separate answers. In the lungs the final destination is the alveoli. This is where the gas exchange takes places to allow oxygen rich blood into the bloodstream and take out the carbon dioxide. In the body once the blood is oxygen rich in the bloodstream it travels through ateries and eventually to capillary beds where gas exchange takes place. The oxygen depleted blood travels back to the alveoli in the lungs and out into the atmosphere.


Place where blood changes from low CO2 to high CO2?

The blood changes from low CO2 to high CO2 in the tissues where oxygen is delivered and CO2 is produced as a byproduct of cellular metabolism.


How do you analyze the effects of exercise on the cardio respiratory system?

When we breathe in through our nose and mouth, the lungs bring in air and then oxygen into our blood, in our lungs there are billions of tiny sacs called the alveoli, it has a huge surface area and the walls are extremely thin, this is when the air in the lungs travels to get to the blood in the capillaries, which it is very small in the body's blood vessels, and it is a part of the microcirculation. The blood is oxygenated, which is carried by red blood cells; this then travels to the heart into the right atrium and down the right ventricle. The oxygenated blood then travels around the whole body to get rid of the waste product; this is known as respiration. When the respiration takes place the oxygenated blood uses energy to turn into carbon dioxide, which is the waste product. When the waste product is being removed, it is carrying out CO2, so this means the oxygenated blood turns in de-oxygenated blood. The de-oxygenated gets pumped through the left atrium, up to the left ventricle, through are lungs and then we breathe out the carbon dioxide; this is known as the gaseous exchange of oxygen into carbon dioxide.


How blood circulates through the body?

Let's start with deoxygenated blood at the heart. It enters the right atrium of the heart, then passes into the right ventricle. From here, it is pumped to the lungs where gaseous exchange takes place. After this, it returns to heart, the left atrium this time. It passes into the left ventricle and is pumped to all the other organs in the body. The deoxygenated blood returns to the heart to complete the circuit.
