CARDIOVASCULAR SYSTEM OF THE HEAD NECK The cardiovascular system consists of the heart‚ blood vessels‚ and the approximately 5 liters of blood that the blood vessels transport. Responsible for transporting oxygen‚ nutrients‚ hormones‚ and cellular waste products throughout the body‚ the cardiovascular system is powered by the body’s hardest-working organ — the heart‚ which is only about the size of a closed fist. Even at rest‚ the average heart easily pumps over 5 liters of blood throughout

1. Why do we need a cardiovascular system? Because we need to get oxygen through our system. 2. Make sure you know which circuits the left and right heart pump into (pulmonary or systemic). Also know the status of blood (fully oxygenated or not) at -the aorta: Left‚systematic‚ and fully oxygenated. -a pulmonary vein: Left side‚ pulmonary‚ and fully oxygenated. Goes from the right side of the body(heart) into the (left) pulmonary veins then goes to the left atrium then to the left ventricle then

Introduction: The cardiovascular system has multiple components that work to ensure an enough oxygen is supplied to the muscles‚ both at rest and during exercise. The objective of this laboratory session was to measure‚ and compare how the cardiovascular system responds to dynamic and isometric exercise. The research question for this lab was “What is the effect of different exercise modalities on the cardiovascular system?”. In response to this research question‚ the following hypothesis was formed

9.2.6 Explain how water moves from the soil to the leaves of a plant. At first water enters the root by osmosis because the soil water has a lower solute concentration of minerals than the epidermal cell cytoplasm (there is a water potential gradient). Water movement across the cortex cell is by two pathways both involving a water potential gradient. The cortex cell cytoplasm has a solute concentration gradient. This moves water symplastically from cell to cell by osmosis. The Apoplastic
