The Circulatory Review Circulatory System A Anatomy Inside

The Circulatory Review

Circulatory System A) Anatomy – Inside the heart • 4 cavities – Two upper cavities are called ATRIUMS – Two lower cavities are called VENTRICLES – Outside the heart • Major Veins (brings blood to the heart) – Inferior and Superior Vena Cava – Pulmonary veins • Major Arteries (brings blood away from the heart) – Aorta – Pulmonary Artery

The Circulatory System

Circulatory System • B) Circulations – Within the Heart • Blood always circulates from the Atrium to the Ventricle – Outside of the Heart • Systemic Circulation – Heart to the cells and cells to the heart • Pulmonary Circulation – Heart to the lungs and lungs to the heart

Circulatory System • Systemic circulation – Goal: • Brings blood from the heart to the cells and from the cells to the heart – Starts from… • Left Ventricle, Aorta, arteries, arterioles, capillaries, venules, veins, Vena Cava (inferior or superior) Right Atrium.

Circulatory System • Pulmonary circulation – Goal: • Brings blood from the heart to the lungs and from the lungs to the heart – Starts from… • Right Ventricle, Pulmonary Artery, lungs, Pulmonary Veins, Left Atrium.

Circulatory System • Blood Components – Red blood cells • Transport Oxygen – White Blood Cells • Protects the system – Platelets • Helps coagulate the blood – Plasma • Liquid component of the blood

Circulatory System • Blood Typing – Red blood cells have different proteins: • A • B • Rh – The combination of these allow us to determine our blood types
