What Are The Parts Of The Heart
The heart has four chambers two on top and two on bottom:
- The two bottom chambers are the right ventricle and the left ventricle. These pump blood out of the heart. A wall called the interventricular septum is between the two ventricles.
- The two top chambers are the right atrium and the left atrium. They receive the blood entering the heart. A wall called the interatrial septum is between the atria.
The atria are separated from the ventricles by the atrioventricular valves:
- The tricuspid valve separates the right atrium from the right ventricle.
- The mitral valve separates the left atrium from the left ventricle.
Two valves also separate the ventricles from the large blood vessels that carry blood leaving the heart:
- The pulmonic valve is between the right ventricle and the pulmonary artery, which carries blood to the lungs.
- The aortic valve is between the left ventricle and the aorta, which carries blood to the body.
What If Fasting Sugar Is Normal But Postprandial High
A high 2 hr pp blood sugar combined with a normal fasting blood sugar is a condition called pre-diabetes or impaired glucose tolerance. No need to bother with a HbAiC. Look for associated atherothrombotic disease risk factors such as cigarette smoking, dyslipidemia, and hypertension and treat those.
What Are Blood Vessels
Blood vessels carry blood around the body. The 3 main types of blood vessels are:
- arteries that carry blood pumped from the heart these are the largest and strongest
- veins that return blood to the heart
- capillaries, which are tiny vessels that connect arteries and veins, and allow blood to come into close contact with tissues for the oxygen, carbon dioxide, food and waste
Blood leaves the heart in large arteries, then moves through progressively smaller ones to the capillaries in tissues. The blood then leaves the tissues in veins that get larger as they get closer to the heart.
The arteries can expand and contract to lower or increase blood pressure, according to your needs.

The Kidneys And Urinary System
Over time, high blood sugar levels can damage blood vessels in the kidneys. This damage prevents the kidneys from filtering waste out of the blood. In time, kidney failure can result.
The NIDDK describe diabetes as one of the main causes of kidney disease. It affects 1 in 4 people with diabetes.
Diabetic nephropathy is kidney disease that affects people with diabetes. Learn more here.
Diabetes increases the risk of a number of eye problems, some of which can lead to vision loss.
Short-term problems include blurred vision, due to high blood sugar. Long-term complications include:
What Does The Heart Do
The heart is a pump, usually beating about 60 to 100 times per minute. With each heartbeat, the heart sends blood throughout our bodies, carrying oxygen to every cell. After delivering the oxygen, the blood returns to the heart. The heart then sends the blood to the lungs to pick up more oxygen. This cycle repeats over and over again.

Where Does Sugar Leave The Body
After your body has used the energy it needs, the leftover glucose is stored in little bundles called glycogen in the liver and muscles. Your body can store enough to fuel you for about a day. After you havent eaten for a few hours, your blood glucose level drops. Your pancreas stops churning out insulin.

How Does Blood Enter The Heart
Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle.
Diseases Of Blood And Blood Vessels
The blood can be affected by trauma or diseases in other parts of the body leading to anaemia, a lack of red blood cells that reduces supply of oxygen to tissues, or polycythaemia, in which there are too many red blood cells. Also, there are cancers of blood cells like leukaemia.
Problems with blood vessels can also lead to high blood pressure, heart attack andstroke.

Sexual Health And Fertility
Diabetes-related damage to blood vessels and the autonomic nervous system may have a negative effect on sexual function and the bodyâs ability to send and respond to sexual stimuli.
Erectile dysfunction is more than three times more likely to develop in men with diabetes, and it can appear 10â15 years earlier than in those without the condition.
Other ways in which diabetes can affect peopleâs confidence in their sex life include:
- the conditionâs impact on mental health
- worry that sex may lower glucose levels, leading to hypoglycemia
- uncertainty about what to do with an insulin pump
However, there are ways of overcoming all of these problems.

Where Does Sugar Enter The Blood Conclusion
Now, as we know the prime reasons where sugar enters the blood, we must keep a track of our daily habits. It is not difficult to control blood sugar, yet willing to have a healthy body will help you even if you are a diabetic patient. Sugar in our blood is necessary to do our daily chores but there should not be excessive sugar.
Success is of no use if you do not possess a healthy body. Why earn money, if there is no peace in your mind, and your relationships only offer you great stress. Eat honestly, exercise regularly, meditate, stay active either way and surround yourself with happy people. Let not the disease take away your happiness or your right to live happily. Your health is precious and hence needs your proper attention and care.

Blood And Blood Vessels
Blood, the heart and the vessels that carry blood around the body together make up the cardiovascular system. They are vital for carrying nutrients, oxygen and waste around the body.
Blood is made of cells and plasma. There are 3 main types of blood cells red cells, white cells and platelets. All are made in the marrow found in many bones.
Red blood cells deliver oxygen from the lungs to the rest of the body, and carry waste products to be released by the lungs or the kidneys. Red blood cells contain haemoglobin, which is the protein that binds and releases oxygen.
White blood cells are part of the immune system. They detect and fight infections or foreign molecules that enter the body.
Platelets are small cells that help the blood clot.
Plasma is the clearish fluid that carries the cells. It also carries the nutrients from our diet such as sugars, fats, proteins, vitamins and minerals.
As well as carrying cells, nutrients, oxygen and waste, blood also helps to regulate body temperature.
How Does The Heart Beat
The heart gets messages from the body that tell it when to pump more or less blood depending on a person’s needs. For example, when you’re sleeping, it pumps just enough to provide for the lower amounts of oxygen needed by your body at rest. But when you’re exercising, the heart pumps faster so that your muscles get more oxygen and can work harder.
How the heart beats is controlled by a system of electrical signals in the heart. The sinus node is a small area of tissue in the wall of the right atrium. It sends out an electrical signal to start the contracting of the heart muscle. This node is called the pacemaker of the heart because it sets the rate of the heartbeat and causes the rest of the heart to contract in its rhythm.
These electrical impulses make the atria contract first. Then the impulses travel down to the atrioventricular node, which acts as a kind of relay station. From here, the electrical signal travels through the right and left ventricles, making them contract.
One complete heartbeat is made up of two phases:

Where Is Sugar Removed From The Blood
Those who monitor their blood sugar levels know the importance of glucose.
Glucose is an important source of energy for your body. Think of it as the gasoline that fuels the engine of the human body.
Your body turns carbohydrates naturally present in the foods you eat and converts them into glucose.
So now we know how glucose gets into your system. But where is sugar removed from the blood?
In addition to your blood cells consuming glucose for energy, your liver plays an important role in the production and healthy removal of sugars from the blood. In this post, we will examine the process.
If you are one of the millions of people who monitor their blood sugar levels, you likely understand the important role glucose plays in overall health. But you might not understand exactly where sugar is removed from the blood.
Your liver is the train station where a lot of the action takes place. Your liver produces glucose from carbohydrates found in the foods you eat, then stores the carbohydrates and releases them when energy is needed by your body.
If this sounds like a very scientific process, thats because it is. But dont worry! Well break down the process so that it is easily understandable.
Check out some common questions and their answers below.
How does blood sugar work?
After you eat foods with carbohydrates, fats or proteins, your body converts these foods into sugars or glucose that your bodys cells can then use for energy. This work is done primarily by the liver.

What Do You Think Causes Heartbeat Sounds Quizlet
Why does the heart make a lub-dub sound? Closure of the valves causes the characteristic sound of the heartbeat: lub-dub. When the valves close it causes turbulence of the blood. As the turbulent blood knocks against the walls of the ventricle they vibrate and the sound waves created by the vibration can be heard.

- Stress: The Most Ignored Reason
Shocked? Yes, its not the sugar in the food you have consumed, but sugar caused by stress. Feeling stress is the reason behind where does glucose comes from and is affecting our health badly. Unfortunately, we tend to feel stress very often. Anxiety about our work at the office, finances, our family, and other reasons lead to stress that in turn interrupts the working of the insulin and thus causes diabetes. According to various studies, we encounter hundreds of reasons which cause stress.
Now, if you are suffering from varying blood sugar levels, then it is your prime responsibility to stay away from it. Do practice yoga, meditation, cardio to keep yourself healthy.
- Food: Main Culprit For The Abnormal Blood Sugar
A very famous saying says, You will be what you eat.
It is right as if you consume food with too much calories you will gain weight and may suffer from diabetes, heart problems, etc. We all are aware that whatever we eat, the carbohydrates inside that food turn into glucose. The stomach and the intestine absorb the glucose that gets mixed with blood. Hence, that is how and where does sugar enters the blood in the form of glucose.
Here, we must know that not all food are bad. Mostly junk food like pizza, burgers, cold drinks, alcohol, cakes, cookies are responsible for the increasing and decreasing levels of blood sugar in your body. One must care for the food ones taking in.

A. How is the blood in the pulmonary arteries different from blood in other arteries?
What Are The Parts Of The Circulatory System
Two pathways come from the heart:
- The pulmonary circulation is a short loop from the heart to the lungs and back again.
- The systemic circulation carries blood from the heart to all the other parts of the body and back again.
In pulmonary circulation:
- The pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide. The blood then returns to the heart through the pulmonary veins.
In systemic circulation:

What Does The Circulatory System Do
The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart.
The circulatory system carries oxygen, nutrients, and to cells, and removes waste products, like carbon dioxide. These roadways travel in one direction only, to keep things going where they should.
