Unit 12 Circulatory & Lymph

1. ARTERY VEIN CAPILLARY ARTERIES- carry blood Away from heart clean oxygenated blood except for Pulmonary Artery VEINS- carry blood towards the heart “dirty” blood with wastes except for Pulmonary vein CAPILARIES- exchange of blood between arteries and veins

Arteries and Viens

2. Divisions of Aorta Ascending- heart wall Aortic arch- carotids Thoracic- lungs Abdominal- stomach, liver

3. PULSE Sites to take pulse- carotid- neck radial- wrist brachial- elbow Pulse can be felt as a surge of blood through an artery Adults approx 70 /min Children faster 100/min

4. BLOOD PRESSURE Blood Pressure is the force of blood against a vessel wall as the heart contracts and then relaxes. The contraction number is the SYSTOLIC. The relaxed number is the DIASTOLIC 120/80 is an example of a normal adult BP

5. What are the 3 Functions of the LYMPH System? Remove excess fluids from tissue Absorb fat Defend body from disease

VOCABULARY Antigen- foreign invader ANTIBODY- immune system produces these to fight antigens Myocardium- heart muscle Endocardium- inner layer of heart wall Systolic- BP reading during contraction Diastolic- BP reading during heart at rest

Vocab Continued Plaque- fatty deposit that clogs arteries Atheriosclerosis- disease of arteries, they harden due to plaque build up Hypertension- High blood pressure
