Basic Anatomy: Emergency Medical Technician Quiz!

The pulmonary artery carries oxygen-poor blood from the heart to the lungs. This is because the pulmonary artery is the only artery in the body that carries deoxygenated blood. Once the blood reaches the lungs, it undergoes oxygenation and becomes oxygen-rich before returning to the heart.

The term "palmar" refers to the palm of the hand. It specifically describes something that is related to or located on the palm. This term is commonly used in medical and anatomical contexts to describe structures or conditions that affect the palm of the hand.

The trachea, also known as the windpipe, is a tube that connects the larynx to the bronchi. It allows air to pass through to the lungs. The trachea splits into two branches called bronchi, with one bronchus leading to each lung. These bronchi further divide into smaller tubes called bronchioles, which eventually lead to the alveoli, where gas exchange occurs. Capillaries are tiny blood vessels, and valves are structures that prevent the backflow of fluid. Therefore, the correct answer is bronchi, as it accurately describes the splitting of the trachea into two branches.

The term bilateral refers to something that occurs on both sides. In this context, it means that it refers to both sides of the body, such as both lungs.

When a patient is in a supine position, it means that they are lying face up. This position is commonly used in medical settings for various procedures and examinations. Being in a supine position allows for easy access to the patient's front side, making it convenient for healthcare providers to perform assessments and administer treatments. Additionally, it helps promote comfort and relaxation for the patient.

The rings of the trachea consist of cartilage. Cartilage is a tough and flexible connective tissue that provides support and structure to various parts of the body. In the trachea, the rings of cartilage help to keep the airway open and prevent collapse during breathing. This allows for the smooth passage of air into and out of the lungs. The presence of cartilage in the trachea also helps to protect the delicate tissues of the airway from damage.

This statement is true. When referring to left and right, it is more accurate to use the perspective of the patient, not the speaker. This ensures that there is no confusion or miscommunication when discussing specific directions or body parts.

The larynx, commonly called the voice box, is the structure that contains the vocal cords and connects to the opening of the trachea. It is responsible for producing sound and allowing us to speak. The nasopharynx, pharynx, and oropharynx are all parts of the throat, but they do not specifically contain the vocal cords or connect to the trachea like the larynx does. Therefore, the correct answer is larynx.

The bone between the shoulder and the elbow in the upper arm is called the humerus. The humerus is the long bone that extends from the shoulder joint to the elbow joint, and it is the largest bone in the upper limb. It plays a crucial role in the movement and stability of the arm, allowing for actions such as flexion, extension, and rotation. The ulna and radius are bones in the forearm, while the carpal bones are located in the wrist.

The heart, lungs, and great vessels are found in the thoracic space. The thoracic space refers to the chest cavity, which is enclosed by the rib cage and contains these vital organs. The heart is located in the middle of the chest, while the lungs are on either side. The great vessels, such as the aorta and vena cava, are also located within the thoracic space. This is where the exchange of oxygen and carbon dioxide takes place, and where the heart pumps and circulates blood throughout the body.

The carotid artery is the major artery in the neck and is responsible for supplying blood to the head. This artery plays a crucial role in delivering oxygen and nutrients to the brain, making it an essential component of the circulatory system. The femoral artery supplies blood to the lower extremities, the brachial artery supplies blood to the arm, and the radial artery supplies blood to the forearm and hand. However, none of these arteries are responsible for supplying blood to the head, making the carotid artery the correct answer.

The term "plantar" refers to the sole of the foot. This is the part of the foot that comes into contact with the ground when walking or standing. The plantar surface is typically flat and is covered with thick, tough skin to provide support and protection.

The left lung has two lobes.

The gallbladder is a small sac-like organ located under the liver. Its main function is to store bile, a digestive fluid produced by the liver. When food enters the small intestine, the gallbladder releases bile into the digestive tract to help break down fats. The gallbladder plays a crucial role in the digestion and absorption of nutrients.

The given statement is false. The Trendelenburg position is not a sitting position. It is a position in which the patient is placed on their back with the head lower than the rest of the body. This position is commonly used in medical procedures and surgeries to improve blood flow and provide better access to certain areas of the body.

The skin consists of multiple layers, with the subcutaneous layer being the deepest. This layer is located beneath the dermis and epidermis layers. The subcutaneous layer is composed of fat and connective tissue, and it plays a crucial role in insulation, cushioning, and energy storage.

The cervical vertebrae are a series of vertebrae located in the neck region of the spine. There are a total of seven cervical vertebrae in the human body. These vertebrae provide support and mobility to the head and neck, allowing for movements such as rotation and flexion. Each cervical vertebra is numbered from C1 to C7, with C1 being the topmost vertebra closest to the skull.

The options provided in the question are all valves in the heart except for "ventral". The aortic valve is located between the left ventricle and the aorta, the pulmonic valve is located between the right ventricle and the pulmonary artery, and the tricuspid valve is located between the right atrium and the right ventricle. However, "ventral" is not a valve in the heart.

The midclavicular line is an imaginary line that runs vertically down the center of the body, passing through the midpoint of the clavicle (collarbone). It is commonly used as a reference point in medical examinations and procedures. The nipple is located along this line, making it an anatomical landmark that can be easily identified and used as a reference point.

The brachial artery is located in the upper arm and is commonly used to obtain a pulse in infants. It is also used as a pressure point to control bleeding in all ages from the arm.

The correct answer is tibia. The tibia is the larger and medial bone of the lower leg. It is commonly referred to as the shinbone and is located on the inner side of the leg. The tibia is an important bone that helps support the body's weight and plays a crucial role in movement and stability.

The term "prone" in medical terminology refers to a patient lying on their anterior body surface or "front". This means that the patient is lying face down with their chest and abdomen touching the surface they are lying on.

The term proximal refers to a location that is closer to the midline of the body. This means that it is closer to the center of the body and away from the extremities or joints. It is used to describe the relative position of body parts or structures in relation to the midline.

The formula SVxHR=CO is the correct formula for determining cardiac output. SV represents stroke volume, which is the amount of blood pumped out of the heart with each beat. HR represents heart rate, which is the number of times the heart beats per minute. By multiplying stroke volume by heart rate, we can calculate the cardiac output, which is the total volume of blood pumped by the heart per minute.

The epidermis is the correct answer because it is the outermost layer of the skin and contains various structures such as sweat and sebaceous glands, hair follicles, nerve endings, and some blood vessels. The dermis is the layer beneath the epidermis and the subcutaneous layer is the deepest layer of the skin. Therefore, the epidermis is the layer that includes all the mentioned structures.
