How does the digestive system and the circulatory system work in conjunction during digestion?
First, with the help of digestive system the food is broken down into smaller pieces which we eat and nutrients are separated which are further transported with the help of blood circulatory system.
Where does most absorption of the end products of digestion into the circulatory system?
In the small intestine
What are the factors that affect hemoglobin's affinity for oxygen?
The primary factor that determines how much oxygen is actually bound to hemoglobin is the partial pressure of oxygen (pO2) in the hemoglobin solution.
Where must blood go to get a fresh supply of oxygen?
The alveoli, or air sacs, of the lungs. Blood is returned by veins to the vena cava, and to the right atrium of the heart. The blood is pumped by the heart's right ventricle to the lungs through the pulmonary arteries. The pulmonary veins return the oxygenated blood to the left atrium, where it is pumped by the left ventricle into the body's arteries through the expanded artery called the aorta.
What do your body's cells do with the oxygen they receive?
The oxygen diffuses into the Red Blood Cells (RBCs) in the lungs. The blood goes to the heart and is pumped to the rest of the body. When the blood reaches oxygen deprived tissues, the oxygen moves from the RBCs to the tissues.
What statement correctly describes an interaction of the respiratory and circulatory systems?
The most direct stament that links the two organ systems is simple. When breathing, the oxygen travels down your trachea and into your lungs where it reaches tiny sponge like cells (avioli) covered with very small veins. Once the oxygen recahes there, transfussion occurs where the oxygen goes into the bloodstream and is replaced by carbon dioxide, which you breathe out
Why do you need your circulatory system to keep tissues all over your body alive?
as this gives oxygen to your lungs as you need air to breathe!
Oxygen is transfered into the blood at alveoli. Oxygen travels along the pulmonary vein into the left ventricle of the heart. It then travels along the aorta to the body tissues, gathering impure blood (CO2) along the way. Travels back to the heart via the Vena Cava and all impure blood is emptied into the right atrium of the heart, before it travels back to the lungs via the pulmonary artery.
What is a circulatory system doctor called?
Doctors who deal with the circulatory system are called Cardiologists or Vascular Surgeons, depending on the condition.
What material does the circulatory system transport through out the body?
The heart, lungs, veins, and arteries. The heart pumps oxegen rich blood into the arteries through the aorta. These arteries travel through out your body. After the O2 has been exchanged in the tissue (muscles, skin) it is passed into the veins. The veins carry the oxegen poor blood to the pulmonary vein. The pulmonary vein carries this "used" blood to the lungs. When you inhale, oxegen is mixed into the blood again. When you exhale, the lungs push the rich blood into the heart through the pulmonary artery and the cycle begins again.
How does smoking affect your circulatory system?
Smoking harms the Cardiovascular system by reducing levels of high-density lipoproteins ("good" cholesterol"), and raising levels of triglycerides and low-density lipoproteins ("bad" cholesterol"). It also increases blood pressure and heart rate, while reducing the amount of oxygen available to the body. It makes the platelets in blood become sticky, promoting clotting, and permanently accelerates the rate at which fatty deposits are laid down in arteries.

JOINT STATEMENT ON THE RE-ASSESSMENT OF THE TOXICOLOGICAL TESTING OF TOBACCO PRODUCTS"
7 October, the COT meeting on 26 October and the COC meeting on 18
November 2004.
"5. The Committees commented that tobacco smoke was a highly complex chemical mixture and that the causative agents for smoke induced diseases (such as cardiovascular disease, cancer, effects on reproduction and on offspring) was unknown. The mechanisms by which tobacco induced adverse effects were not established. The best information related to tobacco smoke - induced lung cancer, but even in this instance a detailed mechanism was not available. The Committees therefore agreed that on the basis of current knowledge it would be very difficult to identify a toxicological testing strategy or a biomonitoring approach for use in volunteer studies with smokers where the end-points determined or biomarkers measured were predictive of the overall burden of tobacco-induced adverse disease."
In other words ... our first hand smoke theory is so lame we can't even design a bogus lab experiment to prove it. In fact ... we don't even know how tobacco does all of the magical things we claim it does.
The greatest threat to the second hand theory is the weakness of the first hand theory.
Why do larger organisms need a circulatory system and amoeba do not?
We are eukaryote which means are cells are more advanced than there's. And since we have more cells than a amoeba. Our cells carry oxygen to the brain and other organs in the body. A amoeba dose not have a brain. So it doesn't need a circulatory system.
Do butterflies have closed circulatory systems?
The butterfly's circulatory system consists of a long tubular heart and hemocoel (spaces between organsfor blood to move). The blood is pumped out to tissues through the hemocoel, but it simply seeps back through the tissue, and it doesn't carry oxygen, just nourishment. Air enters through pores called spiracles and moves through tubes through the body, with gas exchange occurring at the ends of those tubes (tracheae).

Closed or open circulatory system in crab?
Frogs have a double circulatory system, which means that circulation goes from the heart to the lungs (where it becomes oxygenated), then returns to the heart, then is pumped to the rest of the body (which takes the oxygen), and then returns to the heart. They have a closed circulatory system, which means that the blood travels through the body in vessels. Frogs have a three-chambered heart.
What is a respiratory system pigment that carries oxygen?
Hemoglobin is an oxygen-carrying pigment in human blood. It includes iron in its makeup.
What does too much fat do to the circulatory system?
As you probably already now, fat (if too much) can easily clog up major arteries, Your body requires energy in order for bodily processes to function. If your body does not have enough calories in a day (this can be through diet and exercise where your forcing your body to burn storage fat) it will turn to your storage fat supply. The first source the body turns to is glycogen. When those sources are nearly depleted, the body begins lipolysis, the mobilisation and catabolism of fat stores for energy. In this process, fats, obtained from fat cells, are broken down into glycerol and fatty acids, which are then used to make energy. The primary by-products of metabolism are carbon dioxide and water; carbon dioxide is expelled through the respiratory system. The heart need blood to function properly, and with all that fat... Your heart is going to have major problems
The recommended intake of fats in the most countries diet is to limit fats to below 30 percent of the total daily caloric intake. One-third of fats should come from saturated fats, with the other two-thirds split evenly between monounsaturated and polyunsaturated fat. It is estimated that in the average American diet (as of 2002), fats make up 42 percent of calories, with saturated fat making up between a third and a half of that amount.
The effect of this excess intake of dietary fat has some well-established implications for the health of overweight Americans. For instance, the consumption of excess amounts of saturated fats has been recognized as the most important dietary factor to increase levels of cholesterol. A high cholesterol level is detrimental to health and leads to a condition known as atherosclerosis. Atherosclerosis is the build-up of cholesterol on the walls of arteries , which may eventually result in the blocking of blood flow. When this occurs in the arteries of the heart, it is called coronary artery disease. When this process occurs in the heart, a myocardial infarction, or heart attack , may occur.
Besides the cholesterol implications due to high fat intake, obesity is a factor in the causation of disease. Being overweight or obese is highly associated with increasing the risk of type II diabetes, gallbladder disease, cardiovascular disease, hypertension , and osteoarthritis .
Do cells use the circulatory or excretory system to get rid of wastes?
Cells use the circulatory system to help get rid of wastes. Diffusion occurs at the tissues, allowing for nutrients and oxygen to enter the cells, and for carbon dioxide and other wastes to be removes from the cells.
The excretory system is a close partner with the circulatory system because they both remove wastes from the body. The excretory system removes excess, unnecessary materials from the body(as opposed to individual cells) so as to help maintain homeostasis within the body. It is responsible for the elimination of the waste products of metabolism as well as other liquid and wastes, such as urine and feces.
So to simplify, individual cells use the circulatory system to remove wastes, while the excretory system removes wastes from the circulatory system.
What is the structure of the cardiovascular system?
The cardiovascular system is a complex structure consisting of the heart as the main pump. The heart pumps blood to the lungs to be oxygenated. Oxygenated blood flows through arteries to areas around the body. De-oxygenated blood travels through veins back to the heart where it is pumped back to the lungs. Its a basic cycle.
Why it is important to circulate blood through the body?
It is important to circulate blood through body. It transfer oxygen and digested food to body cells. From body cells it transfer carbon bi oxide and waste products of metabolism to lungs and kidney respectively. It also circulates the hormones to there target organs.
What system of the human body is made of blood?
Well,circulatory system is made up of BLOOD and heart.
