ATI TEAS 7 Basic Anatomy + Physiology (Cardiovascular System)

Basic recap of the cardiovascular system for the TEAS 7. Images sourced from Kenhub.

Primary function of the cardiovascular system.

Transport hormones, nutrients, and gas.

Composition of blood.

Plasma, platelets, red/white blood cells, and electrolytes.

Composition of plasma.

Lipids, salt, proteins, and water

Veins

Blood vessels that carry oxygen-poor blood back to the heart.

Arteries

Blood vessels that carry oxygen-rich blood from the heart to the rest of the body.

Capillaries

Small blood vessels that branch arteries and veins together.

Right side of the heart

Side of the heart that pumps deoxygenated blood to the lungs.

Left side of the heart

Side of the heart that receives oxygenated blood from the lungs and pumps it to the body.

Right side of heart blood flow:

1.) Superior/Inferior vena cava

2.) Right Atrium

3.) Tricuspid Valve

4.) Right Ventricle

5.) Pulmonic Valve

6.) Pulmonary Artery

7.) Lungs

Left side of heart blood flow:

1.) Lungs

2.) Pulmonary Vein

3.) Left Atrium

4.) Bicuspid/mitral Valve

5.) Left Ventricle

6.) Aortic Valve

7.) Aorta

Superior/Inferior vena cava

Chamber of the heart that carries deoxygenated blood to the right atrium.

Right atrium

Chamber of the heart that receives deoxygenated blood and pumps it into right ventricle.

Tricuspid valve

Heart valve that regulates flow between right atrium and right ventricle.

Right ventricle

Heart chamber that pumps deoxygenated blood to the lungs.

Pulmonic valve

Heart Valve that regulates flow between right ventricle and pulmonary artery.

Pulmonary artery

Two major arteries that deliver deoxygenated blood to lungs.

Lungs

Organ that supplies oxygen to deoxygenated blood.

Pulmonary vein

Veins that carry oxygenated blood from the lungs to the heart.

Left atrium

Heart chamber that receives oxygenated blood from lungs and carries into left ventricle.

Bicuspid/Mitral valve

Valve that regulates flow between left atrium to left ventricle.

Left ventricle

Heart chamber that pumps oxygenated blood from left atrium to aorta.

Aortic valve

Valve that regulates flow between left ventricle and aorta.

Coronary arteries

Blood vessels that supply blood to the heart muscle from aorta.

Coronary veins

Blood vessels that bring deoxygenated blood to the heart. (right atrium).

Atrial septal defect (ASD)

Defect in which there’s an opening in the interatrial septum, causing blood to mix in both atria.

Ventricular septal defect (VSD)

Defect in which there are hole(s) in interventricular septum, causing blood to mix in ventricles.
