No, it contains bone and cartilage and is part of the skeletal system.
bone
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.
Blood tissue
No, it is made of tissue and blood vessels.
Not all, some white blood cells come from lymphoid tissue, especially T-lymphocytes. Plasma proteins in the blood are made in the liver tissue not the myeloid tissue
Intercostal Spaces
Yes. The area in the centre of the ribs is made up of bone marrow, which produces new red blood cells. This process is known as haematogenesis.
Smooth muscle tissue is usually found neam your ribs and it is used to protect the inner part of your ribs from infections.
they are found together because Epithelial tissue is avascular (it contains no blood vessels) and needs to get it's nutrients from the blood vessels in the connective tissue under it.
Blood is a tissue, because the cells in your blood are working toward the same function of tissues.
This is a connective tissue called the lymphatic tissue!
Red bone marrow and lymphatic tissue which includes the thymus gland are all made of hemopoietic tissue. These tissues are made up of stem cells capable of producing blood cells.
