Transport circulation

• Types of Circulatory System


  • Open Circulatory System
  • Close Circulatory System
• Open Circulatory System


  The blood flows freely through cavities since there are no vessels to conduct the blood
• Close Circulatory System


  The blood flows through the arteries and veins connected together by capillaries
• Divisions of Circulatory System


  • Pulmonary Circulation
  • Systemic Circulation
• Pulmonary Circulation


  Blood flows between the heart and the lungs to become oxygenated
• Systemic Circulation


  Blood is distributed to the tissues and other system of the body
• Heart


  • A four-chamber muscular organ
  • Located just behind and just to the left of the breastbone
  • Pumps blood through a network of arteries and veins called the cardiovascular system
• Chambers of the Heart

  • Right Atrium
  • Left Atrium
  • Right Ventricle
  • Left Ventricle
• Right Atrium


  A thin-walled chamber that serves mainly as a blood reservoir and gateway to the right ventricle
• Left Atrium


  Receives oxygen-rich blood from the lungs and pumps it to the left ventricle
• Right Ventricle


  Pumps the oxygen-poor blood to the lungs
• Left Ventricle


  Pumps the oxygen-rich blood to the body
• Valves of the Heart

  • Pulmonary Valve
  • Aortic Valve
  • Tricuspid Valve
  • Mitral Valve
• Pulmonary Valve


  Opens when the atria contract
• Aortic Valve

  Opens when the ventricles contract
• Tricuspid Valve


  Opens when the atria contract
• Mitral Valve


  Opens when the ventricles contract
• Parts of the Animal Circulatory System

  • Inferior Vena Cava
  • Superior Vena Cava
  • Aorta
• Inferior Vena Cava


  Our body's largest vein that carries oxygen-depleted blood back to our heart from the lower part of our body
• Superior Vena Cava


  Second biggest vein that brings oxygen-poor blood from our upper body to your heart
• Aorta

  Main artery that carries blood away from your heart to the rest of your body
• Parts of the Animal Circulatory System

  • Artery
  • Vein
• Artery


  A thick and elastic red-colored muscular wall that carries blood away from the heart
• Vein


  A thinner blue-colored muscular walls that returns blood back to the heart
• Parts of the Animal Circulatory System - Arteries

  • Aorta
  • Carotid
  • Pulmonary Artery
• Parts of the Animal Circulatory System - Veins

  • Pulmonary Vein
  • Superior Vena Cava
  • Inferior Vena Cava
• Capillary


  A tiny one cell-thick vessel that connects the arteries and veins together. It carries blood and nutrients inside the tissues and organs
• Transport Systems in Plants

  • Phloem Transport System
  • Xylem Transport System
• Xylem

  • A tissue composed of dead, hollowed-out cells that form a web of pipes
  • The walls of xylem cells are lignified (strengthened with a material called lignin)
• Simple organisms which have two-cell layer covering get their supply of gases and excrete wastes through DIFFUSION
• simple organism

  two –cell layer covering
• diffusion


  excrete wastes
• Functions of circulatory system

  Circulate blood throughout thr entire body

  Transport of oxygen to cells

  Transport of carbon dioxide to cells

  Movement of immune system components

  Transport of endocrine glands secretion
• Aorta


  Brain to left arm
• Carotid


  Head to right arm to body
• Pulminary artery


  To lungs
