4. Where does blood flow to after leaving the right ventricle?

Left atrium Pulmonary vein Right atrium Pulmonary artery

5. Which one of the following is true?

Pulmonary circulation occurs around the heart Pulmonary circulation helps remove CO2 Pulmonary circulation circulates oxygenated blood Pulmonary circulation delivers nutrients to the body’s tissues

Arteries are thin walls with little muscle Arteries divide into smaller blood vessels called venules Arteries are thick muscular walls Extremely thin walls

7. Define blood pressure.

Blood pressure is the force applied to the walls of the veins as the blood flows through Blood pressure is the force at which the blood diffuses into the muscles Blood pressure is a measure of the force that is applied against the walls of the arteries as the blood flows through Blood pressure is the force applied to the walls of the capillaries as the blood flows through

Gliding Ball and socket Ellipsoid Hinge

22. Which type of joint is Fixed and Immovable?

Synovial Cartilaginous Ligament Fibrous

23. Which of the following is a voluntary muscle?

Cardiac muscle Smooth muscle Skeletal muscle Ligaments
