Three general characteristics of connective tissue are that they are highly vascularized, they recover well from damage and they possess a lot of non-cellular material. Examples of specialized connective tissue include blood, bone, cartilage and lymphoid tissue.Know More
The non-cellular component of connective tissue is called the extracellular matrix. This matrix is composed of proteins and sugars that bathe the cells present in the tissues, though the majority of the matrix is water.
The three main types of cell found in connective tissue are fibroblasts, macrophages and mast cells. Fibroblasts produce the fibers of the matrix, macrophages scavenge the tissue as an immune cell, while mast cells release heparin and histamine in response to stress.Learn more in Human Anatomy
Groups of tissues that work together are called organs. A single organ may consist of several different types of tissue that are organized to carry out a specific set of functions. Organs, in turn, are organized into systems.Full Answer >
Systemic circulation refers to the path blood takes on its route around the body as it brings oxygen to the tissues, while pulmonary circulation is the smaller loop blood takes to the lungs. Each loop runs through a different half of the heart, according to class notes from East Tennessee State University.Full Answer >
The heart and lungs work together to get oxygen to the tissues. The heart pumps the blood, and the lungs put oxygen into it. This oxygen-rich blood then circulates throughout the body to nourish the cells; oxygen-depleted blood gets collected from the tissues to be oxygenated in the lungs.Full Answer >
Capillaries are extremely small blood vessels responsible for the delivery of essential nutrients directly to tissues throughout the body. They also help the body circulate blood and remove waste from its organs.Full Answer >
