Question

Which one of the following is a liquid connective tissue?
A. Areolar tissue
B. Cartilage
C. Blood
D. Ligaments

Answer 1

Hint:- Blood is described as body fluid and is used to deliver the necessary substances. These essential substances include nutrients and oxygen throughout the body. It also transfers waste products such as carbon dioxide from the cells to the lungs. It contains various types of blood cells that are suspended in blood plasma.

Complete step-by-step solution:- Blood is composed of a colorless liquid known as plasma. Blood appears red due to the pigment known as hemoglobin. Blood carries oxygen from the lungs and carbon dioxide from tissues and blood is necessary to maintain heat gain and loss in the body.
Blood contains the blood cells that are of three types. These are-
Red blood cells
White blood cells
Platelets
On the contrary, areolar tissue contains interlacing and loosely organized fibers. They have a lot of blood vessels that are embedded in the matrix. It is a jelly-like matrix.
On the other side, the cartilage has widely spaced cells that are present in the matrix of proteins and sugars. Therefore, it has a rigid matrix.
The ligament is described as a fibrous connective tissue that also possesses a rigid form of a matrix.
Thus, the correct option is (C). Blood.

Note:- During exercise, a cell needs more energy because there is an increase in physical activity. The heart rate increases due to which rate of breathing also increases. During exercise, the digestive system absorbs more nutrients and water from the food and provides energy to the muscle cells.
