Lab Test 4

• Tissues


  Cells with similar appearance and function are grouped into tissues
• Epithelial Tissue

  • Sheets of cells
  • Found over the outside of the body and line organs
• Connective Tissues

  • Scattered cells through ECM
  • Holds tissues and organs in place
  • Many types of connective tissue
• Muscular Tissues

  • Responsible for body movements, including internal organs
  • Three types
  • Cardiac
  • Smooth
  • Muscular
• Nervous Tissue

  • Processing, transmitting, and receiving information
• Organ systems

  • Tissues are combined to form functional and structural units called organs
  • Organs work together for a common purpose
  • Can be organised into organ systems
• Digestive system components

  • Mouth
  • Pharynx
  • Oesophagus
  • Stomach
  • Intestine
  • Liver
  • Pancreas
  • Anus
• Circulatory system components

  • Heart
  • Blood Vessel
  • Blood
• Respiratory system components

  • Lung
  • Trachea
  • Other breathing tubes
• Immune and Lymphatic system components

  • Bone marrow
  • Lymph nodes
  • Thymus
  • Spleen
  • Lymph vessels
• Excretory system components

  • Kidney
  • Ureter
  • Urinary bladder
  • Urethra
• Endocrine system components

  • Pituitary thyroid
  • Pancreas
  • Adrenal
  • Other hormone secreting glands
• Reproductive system components

  • Ovaries or testes
  • and associated organs
• Nervous system components

  • Brain
  • Spinal chord
  • Nerves
  • Sensory organs
• Integumentary system components

  • Skin and its derivatives
  • e.g hair, claws, sweat glands etc.
• Skeletal system components

  • Skeleton
  • Bones, tendons, ligaments, cartilage
• Muscular system components

  • Skeletal muscles
• Digestive system function

  • Food processing
  • Ingestion
  • Digestion
  • Absorption
  • Elimination
• Circulatory system function

  • Internal distribution of materials
• Respiratory system function

  • Gas exchange
  • Uptake of oxygen
  • Disposal of CO2
• Immune and Lymphatic system function

  • Body defence
  • Fighting infections
  • Virally induced cancers
• Excretory system function

  • Disposal of metabolic waste
  • Regulation of osmotic balance of blood
• Endocrine system function

  • Coordination of body activities
  • such as digestion and metabolism
• Reproductive system function

  • Gamete production
  • Promotion of fertilisation
  • Support of developing embryo
• Nervous system function

  • Coordination of body activities
  • Detection of stimuli and formation of responses to them
• Integumentary system function

  • Protection against mechanical injury, injury, infection, dehydration
  • Thermoregulation
• Skeletal system function

  • Body support
  • Protection of internal organs
  • Movement
• Muscular system function

  • Locomotion and other movement
• Oesophagus function

  • carries food from mouth to stomach
• Liver function

  • Detoxification
  • Glucose storage as glycogen
  • Bile production
• Gallbladder function

  • Store and concentrate bile produced by liver
  • Secretes bile to duodenum via bile duct
  • Bile breakdown fat
• Bile duct

  • Transports bile from the liver and gall bladder to duodeneum
• Pancreas

  • Produces pancreatic enzymes for digestion of food
• Hepatic portal vein

  • carry product of digestion from intestines, gallbladder, pancreas, and spleen to the liver
• Lymph nodes

  • Removes foreign matter that should have been absorbed from the blood
• Stomach

  • Mechanical and chemical digestion
• Pyloric sphincter

  • Regulate flow liquid chyme from pyloric limb and duodenum
• Small intestine (Duodenum)

  • Chemical digestion
  • Chyme from stomach mixes with digestive enzyme from pancreas, liver, and specialised cells in intestinal lining
• Small intestine (Jejunum and ileum)

  • absorbs various nutrients and water
• Direction of flow - Arteries

  • Away from heart
