Connective tissue with the fluid matrix is ___________.

Answer Verified Verified
Hint:
This fluid is predominantly responsible for the transportation of substrate through the body to bring nutrients into the cells and remove waste material from them, and has a variety of other functions.

Complete answer:
> Blood is a connective tissue with a mixture of fluids, called plasma, and without fibers. The predominant type of cell, erythrocytes (red blood cells), are involved in the transport of oxygen and carbon dioxide. In the immune response different leukocytes (white blood cells) are also present.
> The types of living cells are red blood cells (RBCs), also known as erythrocytes, and the white blood cells (WBCs), also known as leukocytes. The fluid component of the entire blood, its matrix, is generally known as plasma.
> An erythrocyte is a cell present in the greatest abundance of blood (numbered in millions in a blood sample i.e. the total volume of red blood cells in primates ranges from 4.7 to 5.5 million cells per microliter). Erythrocytes in one species are usually of the same size but differ in size between species.
> When RBCs are released from the bone marrow where they are produced, mammalian erythrocytes lose their nuclei and mitochondria. The red blood cells of fish, amphibians, and avian hold their nuclei and mitochondria in cell life. An erythrocyte's primary role is to bring and provide oxygen to the tissues.
A cytoplasmic fragment of a cell inside the bone marrow is the slightly granular material between the cells. This is called thrombocyte or platelet. Platelets take part in the stages leading to blood clotting to avoid bleeding into damaged blood vessels. Blood has a variety of functions but it mostly brings material through the body to deliver nutrients to the cells and extract waste material from them.

Note: Blood has three primary functions: distribution, protection, and regulation. It is a carriage liquid pumped into all parts of the body by the heart (or an analogous structure), after which it is returned to the heart to continue the operation. Nutrients from the digestive tract and for the rest of the body.
