Simple epithelial tissues have no blood vessels and line or cover structures.

a group of specialized cells first forms into tissue, and a group of tissue forms into organs.
Two kinds of connective tissue make blood cells for the body, myeloid tissue & lymphatic tissue. Myeloid tissue is found in the sternum, ribs & hip bones, and forms erythrocytes; lymphatic tissue is found in the lymph nodes, thymus & spleen, and forms leukocytes.
The heart is a muscle, and as such has multiple tissues. The main tissue is cardiac muscle cells. These are striated, branched muscle cells held together with intercalated discs. Connective tissue forms a sac around the heart, and epithelial tissue forms blood vessels within the heart. Therefore, the heart contains all four types of tissue. It is mostly muscle tissue. Connective tissue forms a protective sac and holds the heart together, epithelial tissue forms the blood vessels, and nervous tissue carries impulses to and away from the heart. this is all true! ~Trenasian was here!
Endothelial tissue forms the inner lining of blood vessels. This thin layer of cells plays a crucial role in regulating vascular tone, blood flow, and the movement of substances between the bloodstream and surrounding tissues.
Connective tissue forms the framework for the lamina propria of the mucous membranes. This tissue provides support and structure to the overlying epithelial cells and contains blood vessels and immune cells that help maintain the health of the mucosa.
Villi are finger-like projections on the lining of the small intestine. After digestion is finished off, the nutrients and digested food goes to the villi, then from the villi to blood capillaries. Blood capillaries are small blood vessels that contain tiny holes through with tissue fluid leaks out. Then, the nutrients go from the blood capillaries to the tissue fluid. The tissue fluid is mainly water, it surrounds the tissues in our body and it forms a continuous link between the blood plasma (liquid part of the blood that helps the blood to circulate) and the cells. After going to the tissue fluid, the nutrients go to the blood plasma and then to the cells where it is used up (oxygen and chemicals from our food is separated from waste materials and carbon dioxide) Arteries carry oxygen from the blood cells to the body cells and veins carry carbon dioxide. After going to the cells, the nutrients go to the tissues. Hope this helped. I was also confused first but then my teacher explained it to me. :)
Cells and tissue working in unison are what forms organs.
Cells are the basic functional units of living things. A groups of cells together forms a tissue. A group of tissues together forms an organ.
The tissue type that forms blood is hematopoietic tissue, which includes the bone marrow and spleen. The tissue that forms fat is adipose tissue, which stores energy and cushions organs. Fibroblasts are found in connective tissue, where they produce and maintain the extracellular matrix.
Hmm well the first one is plasma- 55% of blood tissue I believe. Red Blood Cell-Delivers oxygen to body tissue White Blood Cell-Defends body against foreign materials and disease Platelets-Heals cuts (forms blood clots)
Yes; the brain is part of the Central nervous system itself, and the spinal cord forms a part of the nervous tissue itself. It is all one continuous tissue.
