Diagram Of Blood Tissue. Epithelial tissue is avascular relying on the blood vessels of the adjacent connective tissue to bring nutrients and remove wastes. Mast cells occur in the connective tissue of small blood vessels skin and tissues of the digestive and respiratory tracts.
The veins of the systemic circulation system take the then deoxygenated blood from the body back to the. It takes in deoxygenated blood through the veins and delivers it to the lungs for oxygenation before pumping it into the various arteries which provide oxygen and nutrients to body tissues by transporting the blood throughout the body. It produces blood corpuscles in emergency ie at the time of excessive loss of blood.
Technically blood is a transport liquid pumped by the heart or an equivalent structure to all parts of the body after which it is returned to the heart to repeat the process.
Diagram of cells that arise from hematopoetic stem cells during the process of hematopoiesis. Although the topology of vascular networks is typically quite complex as a first approximation one can think of most. It is a fluid connective tissue. Superficial veins are located close to the surface of the skin and are not located near a corresponding artery.
