Question 3 which type of epithelial tissue present in skin,lining of blood vessels,mouth, kidney tubules.
Answers
Answer:
The cellular portion of blood contains red blood cells (RBCs), white blood cells (WBCs) and platelets. The RBCs carry oxygen from the lungs. The WBCs help to fight infection, and platelets are parts of cells that the body uses for clotting. All blood cells are produced in the bone marrow.
Explanation:
Ans 1 a- Red blood cells (erythrocytes). These carry oxygen from the lungs to the rest of the body.
b-White blood cells (leukocytes). These help fight infections and aid in the immune process. Types of white blood cells include: Lymphocytes. ...
c-Platelets (thrombocytes). These help in blood clotting.
Ans 2 Function. Areolar connective tissue holds organs in place and attaches epithelial tissue to other underlying tissues. It also serves as a reservoir of water and salts for surrounding tissues. Almost all cells obtain their nutrients from and release their wastes into areolar connective tissue.
Ans 3- endothelium :- The lining of the mouth, lung alveoli and kidney tubules are all made of epithelial tissue. The lining of the blood and lymphatic vessels are of a specialised form of epithelium called endothelium.
