What chamber in a frog's heart contains both oxygenated and deoxygenated blood?
The right heart chambers (atrium and ventricle) contain deoxygenated blood. The left heart chambers contain oxygenated blood, since this blood has already been through the pulmonary system.
What is a hypokinetic disease?
Charactirized by associated with, or caused by, decreased motor activity.
AnswerDiseases caused by lack of activity.How does a coronary heart attack occur?
A heart attack or myocardial infarction occurs in areas of the heart that lack blood flow. Blood, carried by coronary arteries around the heart, would normally provide oxygen & nutrition while taking away carbon dioxide. Without oxygen, the area would become necrotic & myocardial cells would die.
Angina, or chest pain, is usually a precursor to a heart attack. Patients that experience chest pain should see their health care provider to possibly undergo a stress test. A cardiac catheterization may be needed to determine which coronary vessel(s), also called coronary arteries, is occluded or blocked. Occlusion occurs due to years of atherosclerosis, or buildup of lipids from diet & hereditary factors. If the left main coronary artery is blocked, usually a CABG (coronary artery bypass graft) is needed. If other arteries are involved, a coronary stent might be another option. If minimal occlusion is found during catheterization, a patient may just require an antiplatelet agent, such as aspirin or clopidogrel.
How is pulse related to heart beat?
Because they're the same. Every time the heart beats it pushes an amount of blood around the body, and that push is what you can feel in the wrists, by the throat or where you prefer to monitor the pulse.
How is the human heart related to te circulatory system?
the heart is related to the circulatory system because the circulatory and the heart sirculate blood through the veins and the whole entire body
Why are the two valves on the left side of the heart where there is high pressure?
It depends on the viewpoint of the observer ! Looking at the heart as if you're standing in front of the patient - the left ventricle and left atrium are on the right of the heart. If you're looking at the heart as if you're standing behind the patient - the chambers are correctly placed.
What Carries deoxygenated blood to the lungs from the heart?
The pulmonary artery Carries blood containing Oxygen From your lungs to your Heart. So the answer you are seeking is Pulmonary Artery.
What does blood circulate that the body needs?
Blood circulates to provide nutrients and remove wastes in body tissues.
What is a list of heart diseases?
There are many different types of heart disease and therefore there are many causes.
A few examples:
Cardiomopathy - an infection of the heart muscle can be caused by a virus
Bacterial endocarditis is infection of the heart by bacteria.
Coronary heart disease, however, is caused by blockage of the arteries that give the heart muscle its blood supply. This can lead to a heart attack. This type of heart disease develops over time especially if you have high cholesterol.
Congenital heart defect is when you are born with a defective heart.
What prevents the blood from flowing in the wrong direction through the heart?
Heart move blood by pumping action mechanism so also called pumping organ of body. Wall of heart is histologically form of cardiac muscles fibers, while internally the heart is formed of a number of chambers interconnected to one another. Human heart which is also called myogenic heart in whcih the cardiac impulse originates in the cardiac muscle fibers and is not broght to the heart by the nerve fiber. In heart a node known as SA node originate the effectve impulse and these impulse travel throughout the heart through bundle of hiss i.e. the network of impulse carring fibers which allow heart to contract and expand in rhythymic manner so the heart cause pulpating sound and also allow the blood to enter and leave out.
Can the heart contain smooth muscle?
No, they are not. Cardiac muscle is a type of involuntary striated muscle found only in the walls of the heart.
This is a specialized muscle that, while similar in some fundamental ways to smooth muscle and skeletal muscle, has a unique structure and with an ability not possessed by muscle tissue elsewhere in the body. Cardiac muscle, like other muscles, can contract, but some of the cells have the ability to generate an action potential, known as cardiac muscle automaticity. Meaning that some of the cells can beat on their own without any nerve stimulation.
What does Heart Foundation do to help?
The purpose of the Heart and Stroke Foundation is to reduce the impact of, and ultimately to eliminate, heard disease and strokes. It does this largely through advancing research and promoting healthy living.
How does sneezing affect heart beat?
That is a myth - no. However, if you are prone to having a heart attack anyway - then doing so could be enough pressure on the circulatory system to trigger one.
Where does the left side of your heart pump blood to?
The left side of the heart receives blood from the lungs before pumping it through the aorta and out to the rest of your body. This is referred to as the systemic circuit. After the body is nourished and oxygenated, the blood returns to the right side of the heart carrying waste and carbon dioxide to the lungs. This begins the pulmonary circuit that ends when the blood, once again, returns to the left side of the heart.
Well think of the heart and blood vessles as a race track. It start at the heart goes all they way around then back to the start so the heart pumps blood to the heart, but also ateries have a layer of smooth muscle that automatically contracts to help the movement of blood.
What does aerobic exercise do to the heart?
The heart is aerobic, and takes up a large amount of oxygen from the passing blood supply. Under anaerobic conditions, such as a blockage of one of the coronary arteries, the heart muscle which loses it's blood supply dies. This is a heart attack.
Where is the ventricles located?
A ventricle is a cavity in an organ. It usually refers to the two lower cavities in the heart, that pump blood into the body and the lungs. It is also used in connection to the series of chambers inside the brain, which are filled with cerebrospinal fluid.
What valve exits the right ventricle?
The pulmonary or pulmonic valve (a semilunar valve) controls blood flow from the right ventricle to the "pulmonary trunk" that branches into the two pulmonary arteries carrying blood to the lungs.
What is the role of the tricuspid valve?
The tricuspid valve is located on the right side of the heart between the right atrium and ventricle. The purpose of the valve is to close when the ventricle pumps blood into the pulmorary arteries that lead to the lungs. The bicuspid valve, or mitral valve, functions similarly to maintain blood flow in one direction only. The bicuspid valve is located on the right side of the heart. Oxygenated blood from the left ventricle is pumped throughout the body as the mitral valve stays closed during compression.
How long in hospital after a heart attack?
My dad just had a massive heart attack 6 days ago. It was as bad as it gets and they told us the whole time that he was probably going to die. It's a miracle that he survived! And now he's been awake for almost 4 days. His short term memory was initially very, very bad and he would forget things minutes after you told him. We see small improvements now, but we are told it will likely take at least a few months to get better, but there is no guarantee that it will come back completely. I am having a hard time finding much solid information about this on the internet, and every nurse I talk to seems to have a little different idea about if he's showing enough improvement for us to feel that he will recover his short term memory loss completely. From what I understand, it is a case by case situation... some people will recover their short term memory, some not at all, and some anywhere in between.
