Chapter 17 Blood flow through the heart EASY

Step 8, left side of the heart

Blood then enters in the LEFT ATRIUM

Step 12, last step left side of the heart

Blood travels up thorough the AORTA, where it is pumped throughout the body

Cardiac muscle cells have ____ channels

Ca+

2 main vessels of coronary circulation

Right and left coronary arteries

Step 1, right side of the heart

The un-oxygenated blood (this is blood that has been "used up" by your body and needs to be resupplied with oxygen) enters the heart through the SUPERIOR AND INFERIOR VENA CAVA.

Step 5, right side of the heart

Then blood is sqeezed in the PULMONIC VALVE

Step 10, left side of the heart

Then blood is sqeezed into the LEFT VENTRICLE

Step 9, left side of the heart

Then blood travels down through the BICUSPID VALVE (ALSO CALLED "MITRAL VALVE")

Step 3, right side of the heart

Then it is squeezed through the TRICUSPID VALVE

Step 11, left side of the heart

Then up through the AORTIC VALVE

Trabelcuae carnae found where?

Ventricles

when ventricles contract

-AV valves close as blood attempts to back up into the atria > pressure rises inside of the ventricles > semilunar valves open and blood flows into great vessels

Goal of the left side of the heart:

to get the richly, oxygenated blood that LEFT the lungs to the body to feed the brain, tissue, muscles, organs etc.)

What is the epicardium

visceral layer of serous pericardium

True or False: The bicuspid valve is located on the left side of the heart.

True, also called "Mitral Valve"

Step 6, right side of the heart

Blood is then shot up through the PULMONARY ARTERY and then enters into the lungs for some oxygen

12 steps of the heart blood flow:

6 left and 6 right

What part of the heart delivers richly oxygenated blood to the body?

Aorta

Which av valve has 2 flaps

Bicuspid/ MITRAL

Step 2, right side of the heart

Blood enters into the RIGHT ATRIUM

Step 4, right side of the heart

Blood enters into the RIGHT VENTRICLE

Step 7, Left side of the heart

Blood enters the lungs through the PULMONARY VEIN

Which layer of the heart is a synonym for visceral layer of serous pericardium

Epicardium (FANCY PEOPLE PARTY etc)

True or False: Pulmonary veins take unoxygenated blood away from the heart.

False

Name of the discharging chamber

Left ventricle

What part of the heart delivers unoxygenated blood to the lungs?

Pulmonary Artery

What part of the heart delivers oxygenated blood to the heart?

Pulmonary vein

On the right side of the heart, blood flows from the right ventricle to the?

Pulmonic valve to the pulmonary artery

The blood enters on the left side of the heart through the ______________ and enters the left atrium. It then passes through the _____________to enter the left ventricle.

Pumonary vein, bicuspid (mitral) valve

STUDY TIP

Since the goal of the right side is to get blood to the lungs always remember that the pulmonic valve and pulmonary artery will be on the right side since it is associated with the lungs. Remember in medical terminology pulmon means lungs. This will help you keep from getting confused with the left side of the heart.

Goal of the RIGHT SIDE of the heart

To get blood to the lungs so it can become oxygenated

Valve that has 3 flaps?

Tricuspid

This marks the exterior boundary between the ventricles

anterior and posterior interventricular sulcus

What is the endocardium

inner lining of the heart
