PART B. TYPES OF CONNECTIVE TISSUES 7. BLOOD: Blood is considered a (highlight one: fluid, loose, dense, semisolid, or solid) connective tissue. Unlike other connective tissues, blood has a liquid ECM (extracellular matrix) called and hormones in the blood. which transports nutrients, waste, Draw blood connective tissue. Red blood cells. Plasma- Draw what you see. Label the cells and fibers (reticular fibers). Platelets In the plasma, you should see 3 types of cells or structures: Erythrocytes are known as red blood cells. They are the tiny pink dots all over the image. Red blood cells carry oxygen in the blood. They do not have nuclei. leukocytes are known as white blood cells. They are the larger, purple dots scattered throughout the image. White blood cells help with immune response and they DO have nuclei. __Platelets_are proteins (non- cellular components) that help with the blood clotting immune response. You may not be able to see them on the image (too low magnification and…

An individual is running to catch their ride share vehicle when they trip and fall with their hands outstretched. The individual looks up and notices an abrasion from the fall on the palms of their hands but there is no blood. What is the reason for the lack of bleeding?   A. The epithelium is avascular (without blood vessels), so the abrasion must not have penetrated all 5 layers on the palm to reach the vascularized (having blood vessels) basement membrane.   B. The epithelium is avascular (without blood vessels), so the abrasion must not have penetrated all 3 layers on the palm of the hand to reach the vascularized (having blood vessels) basement membrane.   C. The epithelium is avascular (without blood vessels), so the abrasion must not have penetrated all 4 layers on the palm to reach the vascularized (having blood vessels) basement membrane.   D. The epithelium is avascular (without blood vessels), so the abrasion must not have penetrated all 6 layers on…
