VARIATION IN MICROVASCULATURELYMPHATIC SYSTEM
Slide3Introduction
Multicellular Organisms Need 3 Mechanisms
--------------------------------------------------------------- Distribute oxygen, nutrients, and hormonesCollect wasteTransport waste to excretory organs
CARDIOVASCULAR
SYSTEM
Slide4CARDIOVASCULAR
SYSTEM
HEART PRODUCES BLOOD PRESSURE (SYSTOLE)
Vessels are structurally
adapted to physical
requirements and
metabolic needs
Slide5CARDIOVASCULAR
SYSTEM
ELASTIC ARTERIES - CONDUCT BLOOD AND MAINTAIN PRESSURE DURING DIASTOLE
Slide6CARDIOVASCULAR
SYSTEM
MUSCULAR ARTERIES - DISTRIBUTE BLOOD, MAINTAIN PRESSURE
ARTERIOLES - PERIPHERAL RESISTANCE AND DISTRIBUTE BLOODCAPILLARIES - EXCHANGE NUTRIENTS AND WASTEVENULES - COLLECT BLOOD FROM CAPILLARIES (EDEMA)
