Histology MCQ Exam Trivia! Quiz

Blood serves the function of transporting a variety of substances throughout the body. It carries oxygen from the lungs to the cells, nutrients from the digestive system to the cells, hormones from the endocrine glands to their target organs, and waste products from the cells to the excretory organs. Additionally, blood transports immune cells and antibodies to fight off infections, and it helps regulate body temperature by distributing heat. Overall, the primary role of blood is to ensure the efficient delivery of essential substances to all parts of the body.

Adipose tissue serves the function of storing lipids and cushioning organs. It is a type of connective tissue that consists of fat cells called adipocytes. These cells store excess energy in the form of lipids, which can be utilized by the body when needed. Additionally, adipose tissue acts as a protective cushion around organs, providing them with insulation and support.

Skeletal muscle creates heat because it is responsible for generating body heat through the process of muscle contraction. When skeletal muscles contract, they produce heat as a byproduct of the energy used. This heat helps to regulate body temperature and maintain homeostasis. Therefore, it is true that skeletal muscle creates heat.

Smooth muscle is found in the walls of hollow organs, such as the stomach and intestines. Its main function is to contract and relax, which helps propel food through the gastrointestinal (GI) tract during digestion. This movement, known as peristalsis, allows for the efficient breakdown and absorption of nutrients. Therefore, the correct answer is "propel food through the GI tract".

Hyaline cartilage is a type of connective tissue that is found in various parts of the body, including the nose, trachea, and joints. Its main function is to provide support and protection to organs and structures. It acts as a cushion between bones, reducing friction and preventing damage. Additionally, hyaline cartilage helps maintain the shape and structure of organs, such as the trachea, by providing support. Therefore, the correct answer is "to protect and support organs."

Osteoblasts are responsible for producing inorganic salts in the bone. These cells are involved in the process of bone formation and play a crucial role in maintaining the mineral composition of the bone. They secrete proteins and other substances that help in the deposition of calcium and phosphate salts, which make up the inorganic component of the bone. Without the activity of osteoblasts, the bone would not have its characteristic strength and structure.

Muscle tissue is composed of myofibers. Myofibers are long, cylindrical cells that make up muscle tissue. They are responsible for the contraction and relaxation of muscles, allowing movement and providing support to the body. These myofibers contain specialized proteins, such as actin and myosin, which interact to generate force. Together, these myofibers form the structure and function of muscle tissue, enabling it to carry out its various roles in the body.

Muscle tissue plays a crucial role in heat production by generating heat as a byproduct of muscle contractions. This helps to regulate body temperature. Additionally, muscle tissue is responsible for maintaining posture by providing support and stability to the body, allowing us to stand and sit upright.
