What is the Cardiovascular System

The cardiovascular system contains of the heart, blood vessels, and the blood.

The main purpose is to supply the whole body with blood and oxygen.

The Heart

The heart is a muscular organ which provides blood with oxygen around the whole body through the blood vessels.

The right half pumps blood to the lungs through the pulmonary arteries to the lungs.

When it returns to the left side of the heart, it is pumped into the aorta, which is the large artery connected to arteries throughout the body.

Chambers of the Heart There are four chambers in the heart: Right

ventricle, left ventricle, right atrium, and left atrium Ventricles-The right ventricle receives oxygen

depleted blood and the left ventricle pumps blood with oxygen.

Aorta- The aorta arises from the left ventricle of the heart, then flows down to the abdomen,

where it goes into two smaller arteries.

Blood

The blood in the cardiovascular system carries gases, hormones, nutrients, and wastes.

Oxygen, nutrients, and certain hormones are carried to the cells; and carbon dioxide, wastes, and certain hormones are carried away from the cells

Different Types of Blood

There are two types of blood cells: red blood cells: Blood cells that carry transport

oxygen throughout the body and get rid of harmful carbon dioxide.

White blood cells: Blood cells that protect the body from viruses and bacteria that can infect the body and can also help in an allergic response.

The Blood Vessels

Blood flows through your body in a complex system of tubes called blood vessels.

Blood vessels carry blood to every part of your body. At each tissue or organ in your body, blood makes an exchange—it "drops off" oxygen and nutrients and "picks up" waste products that were produced after osmosis.(toxins and carbon dioxide).

After the exchange, blood returns to your heart.

What carries the Blood

There are many streams of blood flow throughout the body including veins, arteries, and capillaries.

Veins- carrying mainly oxygen-depleted blood toward the heart.

Arteries- carries oxygen rich blood away from the heart

Capillaries- connect the arteries and the veins where the nutrients and gases gets exchanged

Disorders

The cardiovascular system can be faulty and many disorders involved with the heart, the blood, and other things can affect one's health.

One Major disease is Sickle Cell Anemia Sickle Cell is when your body produces blood

cells that are crescent shaped and the blood gets clogged in the capillaries
