Why does the heartbeat increase after a vigorous exercise?
If your heart rate increases AFTER running, there is something wrong and you need to see your doctor. Heart rate increases WHILE you are running, and should start to come down after the running stops.
What are some congenital conditions classed as congenital myopathies?
Congenital myopathies are a group of myopathies, usually present from birth, that display structural changes in the skeletal muscles. The list of diseases defined as congenital myopathies varies.
How does the body maintain homoestasis?
The body maintains homeostasis through regulation of external events that would impact internal affairs. Sweating, drinking water, breathing deeper are all example of external events impacting on internal reactions.
Why is the circulatory system called a double loop?
There are two loops to the human heart, a pulmonary loop and a systemic loop. All of the oxygen-poor blood returns to the heart via the right atrium and flows into the right ventricle. When the right ventricle contracts blood is forced into the pulmonary arteries to the lungs to receive fresh oxygenation before returning to the heart. That is called the pulmonary loop, pulmonary referring to the lungs. When the freshly oxygenated blood returns to the heart it will flow into the left atrium and then the left ventricle. The left ventricle will squeeze blood into the aorta which delivers the oxygenated blood to the rest of the body. That is known as the systemic loop, as in the body systems. When the deoxygenated blood drains from the body tissues back through the venous system, it will empty into the right atrium of the heart beginning the process all over again.
Do amphibians have a single loop circulatory system?
no they have double loop circulatory system but the difference is that they have single ventricle.
How does the circulatory system transport and distribute nutrients?
The circulatory system is like a train, bringing different things to different places. The circulatory system transports and distributes nutrients through arteries and veins.

What system do blood vessels belong to?
blood vessels are a part of the circulatory system along with the blood and heart
What are the two differences in both the plant and human transport system?
Plants depend on photosynthesis to convert the energy from the sun into nutrients.
These nutrients are transported by means of sap to the parts of the plants where they are needed to encourage and nurture growth.
Humans depend on the vitamins and other nourishment in food for growth. These nutrients are transported by means of blood, which is pumped by the heart through the arteries and veins to those parts of the body where it is required.
How does the circulatory system do its job?
You have things called arteries that carry the blood full of oxygen throughout your body. Right below your jaw you can feel your pulse. This is one of your arteries pumping blood to your brain. Once the blood has used up all of its oxygen, it is pumped back to your heart through your veins to receive more oxygen.
What is the decrease of platelets in the circulatory system called?
Thrombocytopenia which occurs in multiple diseases such as Dengue Fever.
Is blood a tissue in the circulatory system?
Blood vessels can be termed as organs, since an organ is a group of http://wiki.answers.com/dictionary/Tissuesthat perform a specific http://wiki.answers.com/dictionary/Functionor group of functions.
The function of blood vessels is to circulate blood to various parts of the body.
The tissues that make up blood vessels(arteries and veins) are- endothelial tissue(endothelium)-tunica intima, smooth muscle or muscular tissue- tunica media and connective tissue- tunica externa, while capillaries only contain endothilial tissue.
How is the work of the respiratory system related to the respiratory system?
It is related to the Circulatory system, because the blood travels to the lungs to receive oxygen for oxygenation.
Also, it is related to the nervous system because the nervous system controls the breathing rate.
What is the medical term meaning pressure against the arterial walls when the heart is at rest?
Blood pressure (abbreviated BP) is the pressure of blood against the walls of a vessel. The rhythmic beating nature of that pressure, caused by the alternating ventricular contraction and relaxation in the heart, is the pulse (abbreviated P).
Blood pressure has two values - the systolic blood pressure and the diastolic blood pressure.
When the heart beats, it pushes blood through the arteries to all of the tissues in the body. It is at this point that the pressure from the blood against the artery walls is at its highest and this value is the systolic blood pressure.
When the heart is at rest, in between beats, the pressure on the artery walls is much lower and this value is known as the diastolic blood pressure.
- blood pressure
Circulatory system consist of what liquid?
The liquid organ of the circulatory system is blood. The liquid portion of the blood, minus the formed elements, is the plasma.
Do the valves keep the blood flowing in the right direction?
Each flap is called a cusp,and forms a portion of a heart or venous valve.
Related Information:
Bicuspid, or mitral valves are comprised of two cusps. Tricuspid valves are comprised of three cusps. These cusp structuresare called valves.
The arteries and veins around the body have valves too, and they work in more or less the same way - stopping blood from going backwards.
Usually the aorta doesn't rupture without prior weakening. Either the artery has a weak wall to start with (due to genetic defects in connective tissue and the like) or it has a normal wall but acquired factors such as cholesterol deposition may weaken them. Once the wall is weak, the artery dilates into what is known as an aneurysm, which then ruptures under high blood pressure or slight physical trauma such as a punch to the chest or the abdomen.
What are the parts of the circulatory system where oxygen-poor blood is found?
In the circulatory system, deoxygenated blood is found on the right side of the heart, in the pulmonary artery, and in the systemic veins. The pulmonary artery brings low-oxygen blood to the lungs. The systemic vein carry deoxygenated blood from the body tissues to the right atrium.
What is the over all function on the Circulatory System?
The overall function on the Circulatory System is to pump blood all over the body. The heart is the main part of the system.
People consume nicotine by smoking tobacco products, using snuff or chewing tobacco, chewing nicotine gum or using a nicotine patch. Nicotine gum and the nicotine patch are made to be used in an effort to quit smoking. Snuff can be taken orally or sniffed through the nose, although the latter is an outdated practice.
Why is earth system resemble a closed system?
The state of the Earth's climate is dependent on the amount of energy stored by the entire system, and in particular the balance between the amount of energy Earth receives from the Sun, in the form of light and ultraviolet waves, and the amount of energy the Earth releases back to space, in the form of infrared heat energy.
