Functions of the Circulatory System To carry digested food from the small intestine to all body parts. To carry oxygen from the lungs to the rest of the body. To aid in the disposal of all wastes from the body. To distribute heat. To fight diseases.

selssels Components of circulatory system Heart Blood Blood vessels

The Heart Location – left side of chest cavity Size- As big as closed fist Mass-between 250 and 350 grams

The blood vessels

Artery-Vein Comparison Veins Arteries Transport blood towards the heartTransport blood away from the heart Carry De-oxygenated Blood (except in the case of the Pulmonary Vein) Carry Oxygenated Blood (except in the case of the Pulmonary Artery) Have relatively wide lumens Have relatively narrow lumens Transports blood under lower pressure (than arteries) Transports blood under higher pressure (than veins) Have valvesDo not have valves

Internal structure of human heart 1. The heart is divided into four main chambers: The upper chambers - left and right atria - receiving chambers Two lower chambers - right and left ventricles- discharging chambers. [ [ 2. Septum-thick wall of muscle separating the right side and the left side of the heart 3. Pericardium-double-walled protective sac 4. Valves – Tricuspid and bicuspid 5. Aorta – Main artery 6. Pulmonary artery and pulmonary vein

Double circulation Pulmonary circulation Systemic circulation Deoxygenated blood is pumped to the lungs via pulmonary artery and oxygenated blood returned to the heart via the pulmonary vein. Systemic circulation is the circulation of the blood to all parts of the body except the lungs

RA The cardiac cycle

Path of blood circulation

Blood pressure Force that blood exert against the wall of a vessel Systolic pressure The pressure of blood during ventricular systole (contraction) 120 mm of Hg Diastolic pressure The pressure of blood in artery during ventricular diastole (relaxation) 80 mm of Hg

Measuring blood pressure- Sphygmomanometer

Recapitulation
