|
What are the 3 different types of compound glands?
|
Compoun tubular, compound alveolar, compound tubuloalveolar
|
|
|
Explain all the connective tissues
|
Connective tissue proper: Loose(areolar.adipose.reticular)/Dense(dense regular.irregular.elastic)
Fluid connective tissue: blood(cardiovascular)/lymph(lymphoid system) Supporting connective tissue: cartilage(hyaline.elastic.fibrous)/bone(solid crystalline matrix) |
|
|
Fixed cell types
|
1. Fibroblasts: produce connective tissue fibers
2. fibrycytes: maintain connective tissue fibers and matrix 3. Fixed macrophages: phagocytoize pathogens 4. Adipocytes: store lipid rserves 5. Mesendchymal cells: conn. tiss. stem cells 6. Melanocytes: syntheisze melanin |
|
|
Wandering cell types
|
1. free macrophages: mobile/traveling phagocytic cells
2. Mast cells: stimulate local inflammation which histamines are released in cell for diffusion/osmois to occur and more fluid will leave the and skin will swell 3. Lymphocytes: participuate in immune response 4. Neutrophils and eosinphils: phagocytic blood cells that mobilze during infection |
|
|
Where is areolar tissue located?
|
Dermis, digestive, respiratory, urinary tract
|
|
|
Where is adiposed tissue located and what does it do?
|
Deep to the skin, buttocks, breasts, kidneys. Provides padding
|
|
|
WHere is hyaline cartiliage located and what does it do?
|
Betweent ips of ribs adn bones of sternum. Provides stiff but flexible support
|
|
|
What is reticular tissue found and where is it located?
|
Live, kidney, spleen and provides supporting framework
|
|
|
Integumentary system is composed of what
|
Cutaneous membrane (epidermis(strat squa)/dermis, which nourishes epidermis) and accessory structures are (hair follicles, exocrine glands, and nails)
|
|
|
Explain carpal tunnel syndrome
|
Repetitive stress disorder on flexor tendons leads to pressure on median nerve. Treat with anti-inflammatory or stabilize with splint.
|
|
|
What is blood made out of ?
|
45% of volume is cells, 55% is plasma. Total volume is 5 liters and you can lose 0.5-1 without problems
|
|
|
Functions of the blood
|
transport oxygen to body tissues and CO2 backt o lungs. Nutrients, waste products, regulating temperature(vasodilate)
|
|
|
What is plasma made out of?
|
90% water, 10% proteins(help regulate things for diffusion) ALBUMINS: maintain osmotic balance FIBRINOGENS: clotting protein GLOBULINS: immune response antibodies, and then 1% salts
|
|
|
Erythrocte: RBC shape
|
Biconcave and has 4 binding sites for oxygen
|
|
|
Hemoglobin: If its more warmer and acidic it causes hemoglobin to do what
|
release oxygen
|
|
|
Hemoglobin: if its more cooler which is more neutral, it causes hemoglobin to do what
|
Bind oxygen
|
|
|
In the body hemoglobin wants to do what with oxygen? What about in the lungs?
|
Body: its warmer and more acidic so they want to release Lungs: cells want to bind oxygen cuz your breathing outside air which makes it cooler
|
|
|
Leukocytes: White blood cells
|
Neutrophil(50-70%), involved in phagocytosis & multi-lobed
Lymphocytes: 20%, looks like big nucleus and are T-cells/B-Cells which produce antibodies Basophils:1%, large purple granules Easoinophil: 1%large granules, |
|
|
What are platelets
|
Are also called thrombocytes. Adhere to damaged endothelium and have actin/myosin which are conctractile proteins found in muscles
|
|
|
Layers of skin
|
Stratified corneum: keratinocytes(dead simple squamous)
Stratum lucidum: glossy Granulossom: kerin Stratum spinosum: differentiating keratinocytes Stratum germinativum: stem cells Basal Lamina |
