BIOLOGY

• Open Circulatory System: blood flows freely through cavities since there is no vessels to conduct the blood.
• Close Circulatory System: blood flows through the arteries and veins connected together by capillaries.
• Simple Organisms: organisms that have two-cell layer covering.
• What are the division of Circulatory System Pulmonary and Systematic Circulation
• Pulmonary circulation: Blood flow between heart and lungs.
• Systematic Circulation: blood is distributed to the tissues and other systems of the body.
• Heart: a muscle that is about the size of a first, pumps blood throughout the body.
• what are the chambers of the heart? Right Atrium, Right Ventricle, Left Atrium, Left Ventricle

  
• Valves of the heart: Pulmonary Valve, Aortic valve, Tricuspid Valve, Mitral Valve
• Aortic Valve: opens when the ventricles contract
• Mitral Valve: opens when the ventricles contrast the pressure of the blood
• Tricuspid Valve: from left ventricle to right atrium
• Pulmonary Valve: prevent the back low of the lungs from atrium
• Artery: red-colored muscular wall that carries blood away from the heart
• Vein: blue-colored muscular walls that returns blood back to heart.
• Aorta: biggest artery of the heart
• Aorta: transport the blood from the heart to other parts.
• carotid: to heart to right arm to body
• pulmonary artery: to lungs
• State the three parts of artery: pulmonary artery, aorta, carotid
• parts of vein: pulmonary vein, superior vena cava, inferior vena cava
• Capillary: tiny one-cell thick vessel that connects the arteries and veins together.
• Erythrocytes: red blood cells remove waste and deliver oxygen
• leukocytes: white blood cells help to defend the body against infection
• thrombocytes: platelets form a clot and prevent from bleeding
• Deoxygenated Blood:

  Capillaries

  Superior and inferior vena cava

  Right atrium

  pulmonary ventricle

  pulmonary atrium

  pulmonary artery from alveoli of the lungs

  pulmonary vein from the alveoli to the lungs

  left atrium

  mitral valve

  aortic valve

  aorta and carotid

  oxygenated blood
• Nephrons: the functional unit of the kidney where the specion process take place
• Xylem: carries water and minerals upward from roots to different parts.
• Phloem: moves water and nutrients throughout the different parts of the plans
• Xylem: two way flow
• Phloem: one way flow
• Nervous System: rapid communication of different organ
• 2 types of nervous system: Central and Peripheral Nervous system
• central nervous system: combines two information from the entire body
• Peripheral nervous system: consists of the nerves that connect the brain and spinal cord to the rest of the body
• Central nervous system: made up of brain and spinal cord
• Parts of Forebrain: Cerebrum, Thalamus, Hypothalamus
• Cerebrum: controls the personality, mind, intelligence
• Thalamus: process information and relays it to the cerebrum
• Hypothalamus: homeostatic control of most organ
