Organisation of the Human Body Flashcards
Integumentary
Epidermis
Protects: covers surface; Protects deeper tissues; Vit. D production
Integumentary
Dermis
Feeds epidermis; strength; glands
Hair follicles 囊
Sensation from Innervation神经支配
Sebaceous分泌脂质的 glands
Lubricates hair shaft[组织] 毛干 and epidermis – remove waste.
Sweat glands
Thermoregulation: Evaporative cooling(sweat)Breast tissue is modified sweat gland
Sensory感官 receptors感受器
Detects sensations: Touch; pressure, temperature, pain
Hypodermis(We will include in the Integument System)
Fat stores; Attaches skin to deeper layers
Muscular System 肌肉系统 (=skeletal)
Skeletal muscles
Provide skeletal movement control entrances and exits to the digestive and respiratory system and urinary system
Axial中轴 muscles
Provides support and positioning of the axial skeleton.
Appendicular附肢肌 muscles
Support and move and brace limbs
Tendons肌腱 and aponeuroses腱膜
Translate contractile可收缩的 forces into tasksTendon – muscle to bone.
Aponeuroses – most often muscle to muscle connection
Skeletal System 骨骼系统
Bones, cartilage and joints
Cartilage all sorts of bone interfaces
Axial Skeleton: (skull, vertebrae椎骨, sacrum骶骨, coccyx尾骨, sternum胸骨, supporting cartilages软骨, ligaments韧带)
Protects the brain and spinal cord, sense organs, and soft tissues of thorax胸腔 Support body weight over lower limbs
Appendicular skeleton附肢骨骼: limbs四肢 and supporting bones and ligaments韧带
Provides internal support and positioning of the external limbs; supports and enables muscles to move the axial skeleton中轴骨
Bone
Stores minerals
Bone Marrow
Red
Yellow
Red blood cell production (flat bones扁平骨 (pelvis骨盆, sternum胸骨, skull头骨, ribs肋骨; lose some of this with ageing).
Stores of fat cells (found medullary 骨髓的 cavity腔 of long bones; gain with ageing; yellow to red after major bleeding出血)
Nervous System 神经系统
Central Nervous System (CNS)
Control centre Short term control over other systems
Brain
Complex integrative综合 activities
Controls voluntary and involuntary
Spinal cord脊髓
Relays information to and from brain
Performs less complex integrative activities (reflex arc)
Special senses(**also considered part of PNS except for optic nerve which is CNS)
Sensory input to brain relating to sight, hearing, smell and taste and equilibrium
Peripheral Nervous system (PNS)
Links CNS with other systems and sense organs
Endocrine System 内分泌系统
Pineal gland 松果体
Day-night rhythms
Hypothalamus下丘脑/Pituitary gland脑下垂体
Control many other endocrine glands. Regulates growth. Fluid balance
Thyroid甲状腺 gland
Metabolic rate
Calcium levels
Parathyroid甲状旁腺 gland
Calcium levels
Thymus 胸腺
Maturation of lymphocytes淋巴细胞
Adrenal肾上腺 glands
Water and mineral balance (e.g. aldosterone醛固酮) Tissue metabolism (cortisol)Cardio. and Resp. function (adrenaline肾上腺素)
Kidneys (due to major hormone-producing cells)
Red blood cell production
Blood pressure up.
Calcium levels
Pancreas胰腺
Glucose control
Gonads生殖腺
Sexual characteristics and reproduction
Lymphatic System 淋巴系统
Lymphatic vessels淋巴管
Carry lymph fluid (water and protein) and lymphocytes淋巴细胞 from peripheral外围的 tissues to veins of CV system (see next slide)
Lymphatic fluid淋巴液
Lipids (fats and fatty acids) from the gut.
B cells and T cells
Cells that carry out immune responses
Lymph nodes淋巴结 including tonsils扁桃体
Monitor composition of lymph
Defence: Engulf吞噬 pathogens病原体.
Stimulate immune response
Spleen脾
Monitors circulation blood cells Engulfs pathogens Recycle red blood cells Stimulates immune response Like are large lymph node
Thymus胸腺
Controls development and maintenance of the T cell lymphocytes
It produces cells called T-lymphocytes which circulate around the body. These cells are important for cell-mediated response to an immune challenge, such as may occur when we have an infection.
Cardiovascular System 心血管系统
Heart
Propels blood and maintains blood pressure
Blood Vessels
Arteries 动脉
Capillaries毛细血管
Veins静脉
Conduits导管:
From heart to capillaries
Diffusion between blood and interstitial fluids间质液体
Return blood from capillaries to the heart
Blood
Transport of Oxygen and carbon dioxide Transport nutrients and hormones Remove waste Temperature regulation Defence against illness(immune cells) Acid-base balance (-HCO3)
Respiratory System 呼吸系统
