1) Which cell is this 2) Which tissue is this H&E stain

1) Based on the first photo (pink tissue), fill in the blanks below: This tissue belongs to the _____ of the main tissue types. Its morphology based on the view can be described as _____. This type of layering you would find in _____ of the vascular system and alveoli of the lungs.  2) Based on the second photo with the green arrow: 1. What specific tissue type is this? 2. What structure are the green arrows pointing to? 3. What is the cell in these t=structures called? Answer Options: A. 1= connective 2= cell membrane 3= chondrocyte B. 1= cartilage 2= lacunae 3= chondrocyte C.1= connective cartilage 2= lacunae 3= chondrocyte D.1= elastic cartilage 2= lacunae 3= osteocyte E.1= elastic cartilage 2= lacunae 3= chondrocyte

Select the most accurate description comparing the structure and function of the tissue in the air sacs of the lungs and epidermal tissue. O Air sacs of the lungs are lined with elastic cartilage to allow for expansion and contraction of the lobes of the lungs. The epidermis is composed of stratified squamous connective tissue serving as a protective barrier. Air sacs of the lungs are lined with stratified squamous epithelium to allow for expansion and contraction of the lobes of the lungs. The epidermis is composed of muscle tissue serving as a mechanism for movement and a protective barrier. Air sacs of the lungs are lined with ciliated pseudostratified columnar epithelium with goblet cells. The goblet cells produce mucus to trap debris and the cilia move it away from the lungs. The epidermis is simple squamous epithelium serving as a protective barrier. O Air sacs of the lungs are lined with simple squamous epithelium that serves as a thin membrane for gas exchange. The epidermis is…
