The Digestive System and Respiratory Systems connect to the Cardiovascular System – allowing entry of materials into our body.

Cardiovascular System: How our body delivers materials The Cardiovascular System • • • • Blood (Plasma & Proteins) Bone Marrow Blood Vessels Heart Components of Blood Red Blood Cells: Transport Oxygen and Carbon Dioxide White Blood Cells: Assist in our Immune Response Platelets: Important for Clotting Process Components of Blood Red Blood Cells: Transport Oxygen and Carbon Dioxide White Blood Cells: Assist in our Immune Response Platelets: Important for Clotting Process Plasma: Water (92%) and Proteins Plasma Proteins Fibrinogen: Helps Clotting High-Density Lipoproteins (HDLs) carry lipids & cholesterol from the blood and tissues to the liver. Low-Density Lipoproteins (LDLs) carry lipids & cholesterol to the blood and outlying tissues from the liver and small intestine Plasma Proteins Fibrinogen: Helps Clotting High-Density Lipoproteins (HDLs) carry lipids & cholesterol from the blood and tissues to the liver. Low-Density Lipoproteins (LDLs) carry lipids & cholesterol to the blood and outlying tissues from the liver and small intestine LDL and Heart Disease: Heart Attack: Blockage (complete) of a coronary artery. Can lead to the death of heart cells (no O2, glucose). This means your heart may not be able to contract or sustain a normal rhythm. LDL and Heart Disease: Heart Attack: Blockage of a coronary artery. can lead to the death of heart cells (no O2, glucose). Cardiovascular System: How our body delivers materials The Cardiovascular System • • • • Blood (Plasma & Proteins) Bone Marrow Blood Vessels Heart Cardiovascular System: How our body delivers materials Bone marrow is the soft tissue found inside of bones. In humans, red blood cells, white blood cells and platelets are produced by red bone marrow in the heads of long bones This process is known as hematopoiesis Cardiovascular System: How our body delivers materials The Cardiovascular System • • • • Blood (Plasma & Proteins) Bone Marrow Blood Vessels Heart Cardiovascular System: How our body delivers materials Blood Vessels Arteries: Carry blood away from the heart (usually oxygenated) Veins: Carry blood back to the heart (usually deoxygenated) Capillaries: Tiny blood vessels that connect arteries and veins. Where blood bathes cells Cardiovascular System: How our body delivers materials Blood Vessels Arteries: Carry blood away from the heart (usually oxygenated) Veins: Carry blood back to the heart (usually deoxygenated) Capillaries: Tiny blood vessels that connect arteries and veins.
