The Cardiovascular System and Lymphatics System 。 Blood-Transports nutrients to and wastes from cells WBCs-Defend against infection Lymphatics-Transport interstitial fluid to blood Lymph nodes-Contain fixed macrophages
The Cardiovascular System and Lymphatics System • Blood—Transports nutrients to and wastes from cells • WBCs—Defend against infection • Lymphatics—Transport interstitial fluid to blood • Lymph nodes—Contain fixed macrophages
The Cardiovascular System Superior vena cava (main upper vein) Aorta (main artery) Lung Capillaries Heart in lung Inferior vena cava (main Spleen lower vein) Liver Stomach Kidneys Intestine Capillaries in intestines Figure 23.1

Sepsis and Septic Shock 。Sepsis ·Bacteria growing in the blood 。Severe sepsis 。Decrease in blood pressure ·Septic shock ·Low blood pressure cannot be controlled Figure 23.3
• Sepsis • Bacteria growing in the blood • Severe sepsis • Decrease in blood pressure • Septic shock • Low blood pressure cannot be controlled Sepsis and Septic Shock Figure 23.3
