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.
What tissue Flows through the heart and blood vessels?
Connective tissue flows through the heart and blood vessels.
What can you get if the circulatory system doesn't work properly?
If the circulatory system "breaks down", a person could have a fatal heart attack or stroke. Depending on what happened to cause the collapse, a person may feel numbness anywhere in the body, look pail, or go unconscious. If it does not kill a person right away, they should be immediatly taken to the hospital.
How does the circulatory system circulate nutrients?
Most nutrients are just dissolved in the plasma of the blood. They are transported to the cells when the heart pumps the blood through arteries, arterioles and capillaries. Nutrients diffuse through the walls of capillaries and enter cells.
How does an animal's respiratory system depend on its circulatory system?
Both are dependent on each other. The circulatory system is primarily blood flowing through your entire body carrying oxygen, nutrients and healing agents to the body especially vital organs like the brain. The oxygen being carried to and fro is collected via the respiratory system through the lungs. oxygenated blood is then distributed via circulating blood. An example of these two working together would be a patient with no heartbeat and barely breathing. Administering 1st aid would include reviving the heart (which is responsible for circulation) and also artificial breathing (which would assist the respiratory system to carry oxygenated blood to the brain) without the other, none of the aforementioned two would sustain human life.
Discuss the process of respiration?
Respiration involves the processes of inhalation and exhalation. It is used to control breathing through the exchanges of gases and distribution of oxygen.
What happens to a bacterium after it has been ingested by a white blood cell?
They are attacked by the cells lymphocytes
What organs does asthma affect?
Asthma is a condition of the lungs.
The nerves coating the inside of the lungs and the windpipe become sensitive and often restrict for short periods leaving a smaller hole for the air to pass through causing the sufferer to "wheeze".
As a result, the lungs struggle to breath in enough air to maintain the boday and certain organs can become deprived of oxygen for a short period of time, affecting mostly the heart and brain.
Long time sufferers will have scarring on their lungs from past attacks. You will also find their stomach muscles and diaphragm may be enlarged as these muscles are unnaturally used to force air in and out of the lungs during an attack.
(asthma is a long term condition)
The circulatory system provides support for the skeleton?
The veins and arteries are able to wrap tightly around the skeleton, so they will not dislodge.
How does the brain work with the circulatory system?
Answer 1
The limbic system (top of the brain stem including the medulla and pons which is located at the base of the brain) deals with (or regulates) breathing and heart rate.
Answer 2
No doubt. I agree with the medulla oblongata.
Answer 3
It's the Medulla.
What you feel in your wrist is a pulse. The pulse is caused by the heart pumping blood round your body.
What does the digestive system and circulatory system have in common?
The nervous and muscular system are synchronized to respond to each other. The nervous system creates some impulses which make the muscular system respond in order for them to move.
The circulatory system transports waste to which organs?
circulatory system is the trasport system of the body-distributes food nutrients and oxygen,collects and eliminates carbon dioxide and wastes from the different parts of the body
Why doesnt a bacterium need a circulatory system?
The bacterium has very simple life style. Most of them are non pathogenic. It is unicellular. It is very small in size. Every thing that bacterium needs is available in the same cell. So they do not need the circulatory system. That is why the number of bacteria on the earth is estimated to be 5,000,000,000,000,000,000,000,000,000,000. The man is most complicated of all the animals, specially due to his brain. (Although most of them work as per basic instincts!) He needs circulatory system to to have oxygen and nutrients and to carry away the carbon bi oxide and waste products of metabolism. The number of human being is about 7,000,000,000 only.
What is an example of a cell in the circulatory system?
someone please answer this question i need it for homework like now!
