    Osteoblasts are immature bone cells responsible for bone formation. They synthesize and secrete the components of the bone matrix, such as collagen and other proteins, which then mineralize to form new bone tissue. Osteoblasts play a crucial role in the growth and remodeling of bones, as they are involved in the process of bone deposition and bone repair. Once the bone matrix is formed, some osteoblasts become trapped within it and differentiate into osteocytes, which are mature bone cells that maintain and regulate bone tissue.

    • Atrium

    • Aorta

    • Vena Cava

    • Ventricles

    Correct Answer
    A. Ventricles
    Explanation
    The blood that leaves the heart travels through the ventricles. The ventricles are the lower chambers of the heart and they pump blood out to the rest of the body. The left ventricle pumps oxygenated blood into the aorta, which is the largest artery in the body and carries blood to all parts of the body. The right ventricle pumps deoxygenated blood into the pulmonary artery, which carries blood to the lungs to get oxygenated. Therefore, the blood leaving the heart travels through the ventricles before being distributed to the rest of the body.

    • Equal right & left halves

    • Unequal right & left halves

    • Dorsal and ventral parts

    • Cranial and caudal parts

    Correct Answer
    A. Unequal right & left halves
    Explanation
    The sagittal plane divides an animal into unequal right and left halves. This means that when an animal is divided along the sagittal plane, the two resulting halves will not be identical in size or shape. This is in contrast to the other options, which divide the animal into equal right and left halves, or into dorsal and ventral parts, or into cranial and caudal parts. The sagittal plane is an important anatomical reference plane used in biology and medicine to describe the location and orientation of structures within an organism.

    • Fundus

    • Pylorus

    • Duodenum

    • Omasum

    Correct Answer
    A. Pylorus
    Explanation
    The narrow passage between the stomach and the small intestines is called the pylorus. The pylorus acts as a valve that regulates the flow of partially digested food from the stomach to the small intestines. It controls the release of food into the intestines, allowing only small amounts to pass through at a time. This helps to ensure proper digestion and absorption of nutrients in the small intestines.

    All blood vessels that go into the heart enter through the...

    • Vena Cava

    • Atrium

    • Pulmonary Veins

    • Aorta

    Correct Answer
    A. Atrium
    Explanation
    The correct answer is "Atrium" because the atrium is the upper chamber of the heart that receives blood from the veins. It acts as a holding chamber, allowing blood to flow into the ventricles before being pumped out of the heart. The vena cava brings deoxygenated blood from the body into the right atrium, while the pulmonary veins bring oxygenated blood from the lungs into the left atrium. The aorta is the main artery that carries oxygenated blood from the left ventricle to the rest of the body.
