The correct answer is Patella. The patella, also known as the kneecap, is a small bone located in the front of the knee joint. It acts as a protective covering for the knee joint and helps to increase the leverage of the thigh muscles. The femur is the thigh bone, the humerus is the upper arm bone, and the phalanges are the bones of the fingers and toes.

The correct answer is the clavicle. The clavicle, also known as the collarbone, is a long bone that is located in the shoulder region. It is easily identifiable due to its S-shape and is the only long bone in the body that lies horizontally. It serves as a connection between the sternum and the scapula, providing stability and support to the shoulder joint.

A ball and socket joint is a type of joint that allows for a wide range of movement in multiple directions. It consists of a rounded, ball-like end of one bone fitting into a cup-like socket of another bone. This type of joint is found in the shoulder and hip, allowing for movements such as rotation, flexion, extension, and abduction.

Extension refers to the movement that increases the angle between two body parts, typically in the opposite direction of flexion. It involves straightening or stretching a joint, such as extending the arm to reach forward or extending the leg to kick. In this context, extension describes the movement of the arms.

The liver is the correct answer because it is an organ in the human body. It is located in the upper right side of the abdomen and is responsible for detoxifying chemicals, metabolizing drugs, producing bile, and storing vitamins and minerals. The liver also plays a crucial role in digestion, as it produces enzymes that break down fats, proteins, and carbohydrates. Additionally, the liver helps regulate blood sugar levels and produces blood-clotting proteins.

Area C receives oxygenated blood from the lungs.

The mitral valve is located between the left atrium (chamber C) and the left ventricle (chamber D) of the heart. It acts as a one-way valve, allowing blood to flow from the left atrium to the left ventricle during the heart's pumping cycle and preventing backflow.

The correct answer is Left lateral recumbent. This position refers to lying on the left side with the body in a straight line. "Recumbent" means lying down, and "lateral" indicates the side position. This position is often used in medical settings for procedures or examinations.

The correct answer is D because the heart has four chambers, two atria (A and B) and two ventricles (C and D). The ventricles are responsible for pumping blood to the body.
