Lecture 1 Flashcards
what is the 6 levels of structural organization of the human body?
chemical, cellular, tissue, organ, system organismal level
Define what “Tissue” is
Groups of cells that work together to perform a particular function
what is Histology?
Microscopic study of tissues of the body
Name the 11 systems in the body : SMELINCRDUR
Skeletal, Muscular, Endocrine, Lympatic & Immune, Integumentary, Nervous, Cardiovascular, Reproductive, Digestive, Urinary, Respiratory system
what is the Major Component and Principal Function of the Skeletal System?
Component: Bone, joints, cartilage
Function: support & protection (red bone marrow=blood cells, Yellow bone marrow=lipid, mineral storage)
what is the Major Component and Principal Function of the Muscular system?
Component: skeletal muscle
Function: movement posture, heat
what is the Major Component and Principal Function of the Endocrine system?
Component: Hormone producing CELLS and GLANDS
Function: Hormone released for body activity regulation
what is the Major Component and Principal Function of the Lymphatic & Immune system?
Component: Lymphatic Fluid, vessel and lymphatic organs
Function: Defence, transportation of lipids, proteins, lymphoid cell and fluid
what is the Major Component and Principal Function of the Integumentary system?
Component: Skin & Derivatives (hair, nail & sweat/oil glands)
Function: Protection, detect sensation, VITAMIN D SYNTHESIS, thermoregulation
what is the Major Component and Principal Function of the Cardiovascular system?
Component: Blood, Heart & blood vessels
Function: O2, CO2, nutrient, waste transport & water content, temperature, acid/base regulation and defence
what is the Major Component and Principal Function of the Reproductive system?
Components: Gonands & associated organs
Function: Produce/store/transport gametes
what is the Major Component and Principal Function of the Digestive system?
Components: Mouth –> Anus organs (gastrointestinal tract), accessory organs (pancreas, salivary glands, liver, gall bladder)
Function: Digest, Absorb nutrients, eliminate solid waste
what is the Major Component and Principal Function of the Urinary system?
Component: Kidney, Urinary bladder & their ducts (ureters, urethra)
Function: Produce, store, remove urine. Regulate blood volume, assist production of blood cells & balance acid/base
what is the Major Component and Principal Function of the Respiratory system?
Component: Lungs, airways (trachea, bronchi)
Function: O2 & CO2 transfer between blood & air, vocalisation, acid/base regulation
What are the 4 Basic Tissue types?
Epithelial, Connective, Muscle, Nervous tissue
