BIO 116 CH 5 Cardiovascular system PT 1 [Heart Anatomy & Blood Flow]

CH 5

Myocardium

wall of each heart chambers is composed of cardiac muscle tissue

Endocardium

smooth lining go heart chambers

Endocarditis

inflammation of endocardium

Pericardium

a membranous sac that covers the heart

Pericarditis

inflammation of pericardium

Chordae tendinae

attack Atrioventuicalar (AV) Valves

Which parts of the body make up the cardiovascular system?

heart, blood vessels, blood

What are the 3 main functions of the CV system?

transports oxygen & CO2

Transports nutrients & hormones

Transports cells of the immune system

Name the 3 types of blood vessels

arteries, veins, capillaries

arteries

take blood AWAY from the heart

veins

return blood TO the heart

capillaries

tiny thin vessels for gas exchange

Which chambers RECEVE blood?

Right & Left ATRIA

Which chambers DISCHARGE blood?

right & Left VENTRICLES

What are the AV valves?

Tricuspid, Bicuspid (Mitral), Chordae tendinae

Tricuspid

at the opening of the RIGHT atrium into the ventricle

Bicuspid (Mitral)

at the opening of the LEFT atrium into the ventricle

What are the semilunar valves?

Pulmonary semilunar, Aortic semilunar

Pulmonary semilunar

blood flows from the RIGHT ventricle to lungs

Aortic semilunar

blood flows from the LEFT ventricle to rest of body

Where does the RIGHT side pump blood?

to the lungs / Pulmonary Circuit

Where does the LEFT side pump blood?

to the REST of the body / Systemic Circuit

Beginning with the Vena cava, where does the blood flow?

bring oxygen-poor blood from the rest of the body to the heart (RIGHT Atrium)

oxygenated blood

RED, Aorta & Systemic Arteries, Pulmonary VEINS

deoxygenated blood

BLUE, Pulmonary arteries, Systemic VEINS

Name the two circuits of the cardiovascular system

Pulmonary Circuit, Systemic Circuit

Pulmonary Circuit blood flow

heart to lungs

Systemic Circuit blood flow

heart to rest of body

Pulmonary Circuit pathway

RIGHT ventricle through pulmonary arteries,

lungs,

pulmonary veins,

to LEFT atrium

Systemic Circuit pathway

LEFT ventricle through AROTA,

smaller arteries,

arteriales,

capillaries,

venules,

venae cava,

to RIGHT atrium

Hepatic Portal Circulation

Unique blood route through the liver for glucose removal (stored as glycogen) & detoxification of blood
