- Pumping the blood to the rest of body
- Systemic circulation:
- Same thing except does it twice. In this system, blood travels from the heart to the gills, then to the rest of the body, and back to the heart in one circuit.
- Double loop circulation:
- Red blood cells transport oxygen
- Red blood cells:
- the result of something diffusing or being diffused, or a situation where something is diffused
- Diffusion:
- large vessels that carry blood from the heart to the tissues of the body
- Artery:
- capillaries
- Where does the main job ("the real work") of the circulatory system take place?
- To circulate blood, oxygen, co2, and nutrients throughout the body.
- What is the function of the circulatory system?
- Pumping the blood to the lungs
- Pulmonary circulation:
- Blood, blood vessels, heart
- What are the 3 main parts of the circulatory system?
- White blood cells are the "army" of the circulatory system
- White blood cells:
- Return blood to the heart
- Vein:
- left atrium-left ventricle-body-right atrium-right ventricle-lungs- left atrium
- Draw a simple flow chart of the path of blood
- an amine compound released by cells of the body's immune system in allergic reactions that causes irritation, contraction of smooth muscle, stimulation of gastric secretions, and dilation of blood vessels.
- Histamines:
- block the blood flow, the mineral calcium, vitamin K, and a protein called fibrinogen
- Fibrinogen:
- It is a chamber in the heart, two of these left and right, lower
- Ventricle:
- 1. collects oxygen from the lungs, 2. collects nutrients from the digestive tract, 3. collects waste products from the tissues, 4. helps regulate internal environment, 5. helps fight infections, 6. repair damaged blood vessels
- What are the six functions of blood?
- It is a chamber in the heart, two of these left and right, upper
- Atrium:
- between the atria and the ventricles. Blood moving from the atria holds the valves open. When the ventricles contract, the valves close
- Valve:
- a common arterial disease in which raised areas of degeneration and cholesterol deposits (plaques) form on the inner surfaces of the arteries
- Atherosclerosis:
- In this system, blood travels from the heart to the gills, then to the rest of the body, and back to the heart in one circuit.
- Single loop circulation:
- Straw colored fluid that is 90% water, 10% dissolved gases, salts, nutrients, enzymes, hormones, waste products, and proteins called plasma proteins
- Plasma:
- White blood cells produce proteins called antibodies
- Antibodies:
- any of the arteries, veins, or capillaries through which blood flows
- Blood vessel:
- a fibrous membrane that forms a sac surrounding the heart and attached portions of the main blood vessels
- Pericardium:
- an iron-containing protein in red blood cells that combines reversibly with oxygen and transports it from the lungs to body tissues
- Hemoglobin:
- Arteries- pump blood away from the heart...Capillaries- smallest bood vessels, deliver blood to tissues...Veins- return deoxygenated blood to the heart
- What are the 3 types of blood vessels and what does each do?
- cell fragments called platelets make blood clotting possible
- Platelets
- a vein that has become abnormally swollen and knotted as a result of defective valves
- Varicose veins:
- the smallest of the blood vessels
- Capillary:
- The thick muscular wall of the heart. The myocardium is thickest around the left ventricle where the pressure generated by the heart is greatest.
- Myocardium:
- are made possibly by plasma proteins and platelets
- Blood clot:
- white blood cells-fight infection, red blood cells- transport oxygen, plasma- contains dissolved gasses and nutrients (liquid part of the blood), platelets- allow the blood to clot
- What are the 4 main components of blood AND their functions?
- muscle that divides the left to the right
- Septum:
- Pulmonary Valve and Bicuspid Valve
- Specific valves of the heart:
