cardiovascular system study guide

What is the function of the cardiovascular system?

Transport blood to and from

What are five things your blood delivers to your cells

Oxygen, nutrients, water, hormones, white blood cells

What are two things your blood delivers away from yourselves

Water and CO2

What type of tissue is the heart made out of?

Cardiac muscle

Which origin of the body puts oxygen in the blood and move CO2 from the blood

Lungs

How many times does the average healthy heartbeat per minute

72

What are the three functions of your blood?

Clot, fight, infection, infections, transportation

Arteries

Carry oxygenated blood away from the heart

Capillaries

Tiny blood vessels that connect arteries and veins

veins

Carry the deoxygenated blood back to the heart

Carries dark red blood

Veins

Carries bright red blood

Arteries

What color is blood when it enters the lungs

Dark red

What color is blood when it leaves the lungs

Bright red

What color is blue when enters your body cells

Bright red

What color is blood when it leaves your body cells

Dark red

What type of blood is pumped by the right side of the heart?

Deoxygenated

What type of blood is pumped by the left side of the heart?

Oxygenated

What does the right side of the heart pump blood to?

Lungs

What does the left side of the heart pump blood to?

Heart

The human heart is composed of blank chambers

4

Remove CO2 from the blood and adds oxygen to the blood

Lungs

Pulmonary arteries

Carry deoxygenated blood from the heart to the lungs

Systemic veins

Carries deoxygenated blood from the tissue back to the heart

Pulmonary veins

Carries oxygenated blood from the lungs to the heart

Systemic arteries

Carries oxygen in blood from the heart of the tissue

The loop of blood vessels that carries blood to and from the body tissue is known as

Systemic circuit

The loop of blood vessels that carries blood to him from the lungs is known as

Pulmonary circuit

Remove oxygen from the blood and add CO2 to the blood

Body tissue

sinoatrial node

Located in the right atrium wall. Generates impulses 60 to 100x per min. Pacemaker. Triggers the atria to contract. Passed to AV node.

Atrioventricular node

Located between the atria and ventricles. Causes delay in the condition of the heart, allowing the atria to fully empty and close their valves. Send impulses to the AV bundle.

Atrioventricular bundle

Located in the septum. Bundle of his. sends impulses to bundle branches.

Right and left bundle branch

Right branch equals right ventricle. Left branch equals left ventricle. Send impulses to the purkiniji fibers

Purkinje fibers

Spread through the ventricle muscle tissue. Carries impulses through the ventricle and causes them to contract.

Why is the left ventricle thicker than the right ventricle?

The left ventricle pumps blood to the entire body, the right only pumps to the lungs.
