Circulatory System
Circulatory System is the category for questions about the human circulatory system, including questions about the human heart, arteries, and veins.
2,116 Questions
Which function involves the circulatory system working with the respiratory system?
enabling cellular respiration
How the circulatory system works with the nervous system?
The sinoatrial (SA) node of the heart serves as its pacemaker, and receives nerve input from the nervous system in order to initiate the "pumping" activity that controls the circulatory system.
In addition, muscles of blood vessels can expand and contract from signals from the autonomic (sympathetic and parasympathetic) nervous system in order to control blood pressure.
What chambers are filled with oxygen poor blood?
The superior vena cava and inferior vena cava are the two vessels that return oxygen-poor blood to the heart. Both empty into the heart's right atrium.
Does aids infect the circulatory system?
HIV infects the circulatory system (is carried in the blood and other bodily fluids). It weakens the immune system when the person develops full blown AIDS (as a result of contracting the HIV virus).
How the heart compared to a mechanical pump?
Because technically-- a heart is a pump. Not a single one, but a double pump.
The right side of the body collects the deoxygenated blood (dirty sewer water), starting from the superior and inferior venae cavae (small pipes) and drain it into the right atrium. The right atrium drains the deox blood into the right ventricle, which pumps it into the pulmonary trunk.
The pulmonary trunk takes the blood to the lungs where gas exchange will occur (changing of dirty water into clean water) and returned back to the LEFT atrium via the pulmonary veins (clean pipes).
The left atrium pumps the now-oxygenated blood into the left ventricle which pumps it to the aorta (the MAIN pipe).
Through arteries (pipes) the oxygenated blood will be distributed to the whole body as needed (the clean water will be distributed to the houses as needed--some areas won't have that man people living there or those people don't use much water, therefore they won't need that much water).
At the same time, this double pump has its own deoxygenated blood (dirty water) which it needs to get oxygenated (cleaned). This cleaning is done via the coronary sinus and its tributaries (bring in deoxygenated blood into the right atrium).
The oxygenated blood comes out of the aorta via the coronary arteries.
What is the The upper part of the heart is called?
The upper quadrants of the heart are called atria. The right atrium receives the deoxygenated blood that has been circulated throughout the body. This blood then moves through the right ventricle and to the lungs to be oxygenated. This blood then returns to the left atrium, goes through the left ventricle, and into the aorta. The aorta then branches off and circulates through the entire body to bring oxygen to the cells and tissues.
How can you keep circulatory system in good condition?
You Have to exercise and diet. Whole grain foods are healty for the Circulatory system and also, foods that are low in fat.
By exercising everyday and eating fruits and vegetables.
the circulatory system is a system that
How is respiratory system and digestive system related to the circulatory system?
The respiratory system provides oxygen so the body can "burn" (oxidize) the food that is brought into the body through the digestive system. The circulatory system brings nourishment to all cells of the body. The circulatory system exchanges critical gases with the respiratory system; unneeded carbon dioxide is exchanged for much needed oxygen.
What are three major functions of circulatory system?
1. It transports gases (from the respiratory system), nutrient molecules, and waste
materials (from the digestive system).
2. It regulates internal temperature and transports chemical substances that are
vital to health from one part of the body to the other.
3. It protects against blood loss from injury and against disease-causing microbes
or toxic substances introduced into the body.
Does the circulatory system deliver oxygen to cells?
to what tissue? The pulmonary artery carries oxygen depleted blood to the lungs, where the red blood cells exchange carbon dioxide for oxygen. The pulmonary vein carries oxygen enriched blood from the lungs back to the heart. All other tissue requires other arteries to carry oxygen rich blood to them.
Where do veins carry blood to?
First let me start by saying that the are 2 vena cava's the superior and the inferior. the inferior vena cava carries deoxygenated blood from the bodies lower half to the hearts right atrium and the superior vena cava carries deoxygenated blood from the bodies upper half to the hearts right atrium.
When the heart contracts what receives its blood supply?
Blood pressure is the force of blood against the inner walls of arterial blood vessels. Blood pressure rises when the ventricles contract and falls when the ventricles relax. Systolic pressure is the maximum pressure and diastolic pressure is the minimum pressure.
The circulatory system does all this but the blood and plasma are the "part" that you are talking about. The hemoglobin carries the oxygen and some of the waste gas called carbon dioxide but the plasma carries the rest. The plasma is the liquid part of the blood.
How does the blood change in the 3 systems of circulation?
Its as follows
1. respiratory system
2. digestive system
3. excretery system
etc
all the the body internal systems are related to blood circulation.
It is conducted by nerves
What are the three components in the circulatory system?
Depending on the depth of your question, I would say
1) The Heart
2) Arteries
3) Veins
a little more in depth might say
1) Heart
2) Arteries & Veins
3) Capilleries
but I'd probably go with the first three (especially if you don't know what capilleries are).
What is earth considered a closed system?
A system that never be self-contained regardless of matter.
What role does the respiratory and circulatory systems play in the human body?
they are both part of the heart
What allows blood to enter the right atrium?
The vena cava allows blood to enter the right atrium. Unlike the rest of the heart, there are no valves separated the vena cava and right atrium. However blood backflow is not an issue because the pressure difference between the right atrium and the vena cava is not great, and when the heart pumps it partially compresses the vena cava.
How many seconds does it take to circulate blood through the body?
Approximately 23 seconds
I believe this response to be wrong and based on the movie "The Number 23", which is fictional and bases it's theme around the 23 enigma which is selection bias at it's best! To the original person who answered, please research your answers before posting. It is people who post without thought and research who destroy the internet's unique use as an overall research tool and make finding the correct answer for something much harder.
The actual answer is that every body is different and therefore as such each individual has a different time for blood to circulate the whole body. For example, someone who has had their legs amputated would have a quicker circulation time than an average healthy adult. Other factors to be considered are age, weight, health, sex, height, activity, anxiety and stress etc. For an average adult at rest it takes almost 1 minute for a red blood cell to travel the circulatory system.
