Describe The Main Functions Of The Cardiovascular System – Your circulatory system, also known as the cardiovascular system or vascular system, stores energy; Oxygen in your body to use for growth and repair. It transports nutrients and hormones to your body’s cells. Your circulatory system removes carbon dioxide and other waste products that your cells don’t need.

Key components of your circulatory system keep blood flowing to all the cells in your body so you can live:

Describe The Main Functions Of The Cardiovascular System

Low-oxygen blood collects in the right atrium of your heart, one of the heart’s 4 chambers. It moves to the right ventricle where your red blood cells pick up oxygen and pump this blood to your lungs to remove carbon dioxide. Then exhale the carbon dioxide.

Cardiac Cycle: Video, Anatomy, Definition & Function

Oxygen-rich blood returns to the left atrium of your heart; back into your left ventricle. The left ventricle pumps oxygen-rich blood through your aorta. into your veins; Then it absorbs all parts of your body. Along the way, the blood collects nutrients from your small intestine.

As it enters the capillaries, your blood comes into contact with tissues and cells. It transports oxygen and nutrients and removes carbon dioxide and waste products. Now less oxygenated, the blood travels through the veins and returns to the right atrium of your heart, where the cycle begins all over again.

Most CVD occurs when a fatty substance called plaque or atheroma builds up inside the arteries. This causes the blood vessels to narrow over time. Then the blood decreases. This process is called atherosclerosis.

Atherosclerosis can lead to coronary heart disease and ischemic heart disease. Decreased blood supply means less oxygen and nutrients to the heart muscle. This can cause angina or a heart attack that requires emergency medical attention. The most common symptom of a heart attack or angina is chest pain.

When a blocked or ruptured artery cuts off the blood supply to part of the brain, it causes a stroke. A stroke is also an emergency and will require immediate medical attention.

When blood is pumped into the heart’s arteries, Blood pushes against the artery walls. This gives you a reading of your blood pressure. Blood pressure is measured in units called ‘millimeters of mercury’ (written as mmHg). Most doctors consider healthy blood pressure to be between 90/60mmHg and less than 140/90mmHg.

High blood pressure, also known as hypertension, can increase the risk of cardiovascular disease. It is the most common health problem of the circulatory system.

Low blood pressure, also known as hypotension, is a sign of good health for some people, but can be a problem for others. Symptoms of low blood pressure include dizziness or fainting.

The Cardiovascular System (heart And Blood)

The best way to find out how healthy your circulatory system is is to see your doctor and get a heart health check. The heart health exam takes about 20 minutes and is covered by Medicare if you qualify.

The earlier cardiovascular disease is detected, the earlier it can be treated. If you have high blood pressure, it’s especially important to have regular heart health checkups with your doctor.

Low blood pressure is only a problem if it has negative effects on how your body works or how you feel. For example, if you feel See your doctor if you have symptoms.

Growing old There are certain risks that cannot be changed when it comes to cardiovascular health, such as family history or ethnic background. But it can improve your heart health and reduce your risk of cardiovascular disease.

Blood circulates through a network of blood vessels throughout the body to deliver oxygen and nutrients to individual cells and to help remove metabolic waste products. The heart pumps blood around the arteries.

Blood is made up of 45% solids (cells) and 55% liquid (plasma). proteins in plasma; nutrients, hormones, Plasma is mostly water, containing antibodies and dissolved impurities.

(red cells) are small red disc-shaped cells. They contain HAEMOGLOBIN, which combines with oxygen in the lungs and transports it to the body’s cells. The hemoglobin then transports the carbon dioxide waste products back to the lungs. Erythrocytes are formed in the bone marrow in the nodules of bone.
