42 4-4 Connective Tissue Adipose Tissue Adipose cells Adipocytes in adults do not divide Expand to store fat Shrink as fats are released Mesenchymal cells divide and differentiate To produce more fat cells When more storage is needed
43 4-4 Connective Tissue Reticular Tissue Provides support Complex, three-dimensional network Supportive fibers (stroma) Support functional cells Reticular organs Spleen, liver, lymph nodes, and bone marrow
44 Figure 4-10a Adipose and Reticular Tissues Adipose Tissue LOCATIONS: Deep to the skin, especially at sides, buttocks, breasts; padding around eyes and kidneys FUNCTIONS: Provides padding and cushions shocks; insulates (reduces heat loss); stores energy Adipocytes (white adipose cells) Adipose tissue LM 300

53 4-4 Connective Tissue Fluid Connective Tissues Blood and lymph Watery matrix of dissolved proteins Carry specific cell types (formed elements) Formed elements of blood Red blood cells (erythrocytes) White blood cells (leukocytes) Platelets
54 4-4 Connective Tissue Fluid Elements of Connective Tissues Extracellular Plasma Interstitial fluid Lymph
55 Figure 4-12 Formed Elements of the Blood Red blood cells Red blood cells, or erythrocytes (e-rith-ro-sıts), are responsible for the transport of oxygen (and, to a lesser degree, of carbon dioxide) in the blood. Red blood cells account for roughly half the volume of whole blood and give blood its color.
56 Figure 4-12 Formed Elements of the Blood White blood cells White blood cells, or leukocytes (LOO-ko-sıts; leuko-, white), help defend the body from infection and disease. Neutrophil Eosinophil Basophil Monocytes are phagocytes similar to the free macrophages in other tissues. Lymphocytes are uncommon in the blood but they are the dominant cell type in lymph, the second type of fluid connective tissue. Eosinophils and neutrophils are phagocytes. Basophils promote inflammation much like mast cells in other connective tissues.
57 Figure 4-12 Formed Elements of the Blood Platelets Platelets are membrane-enclosed packets of cytoplasm that function in blood clotting. These cell fragments are involved in the clotting response that seals leaks in damaged or broken blood vessels.
58 4-4 Connective Tissue Lymph Extracellular fluid Collected from interstitial space Monitored by immune system Transported by lymphatic (lymphoid) system Returned to venous system
