1. Angina pectoris
• Pain that indicates a heart attack
• Caused by a blockage in the coronary artery
Antibody
• Y shaped proteins
• Created by the immune system
• Clump foreign substances together in the blood
Atrium
• “TOP” chambers of the heart
• Move blood into ventricles
• “Measure” blood for the ventricles to pump
blood
• Connective tissue
• Medium that carries requirements to cells
• Medium that carries wastes away from cells
blood pressure
• Pressure exerting on the INSIDE of blood vessels
• Created by the force of the pumping heart
capillary
• Smallest blood vessels in body
• Materials can enter and exit the blood through capillaries
circulatory (cardiovascular system)
• System of transport in organisms
• Moves materials to and from tissues
Heart attack
• Situation where blood flow is blocked from the heart tissues
• Muscle cells cannot contract
Open circulatory system
• Circulatory system where blood exits the vessels and bathes tissues directly (more primative)
Portal system
• A pathway of blood that begins and ends in capillary flow
• i.e blood flows from the intestine to the liver and then back to the main bloodstream
Systemic circuit
• Circulation of blood from the heart to the body tissues and then back to the heart again.
Tissue fluid
• Fluids surrounding cells
• Contain materials that must be diffused into the cells
• Contain waste materials (from cells) that must be removed
