7.1 The Blood Vessels | 7.1 The Blood Vessels | 7.1 Blood Vessels |
- A series of vessels
delivers blood from the heart to the capillaries, where exchange of substances
takes place, and then another series of vessels delivers blood from the
capillaries back to the heart.

7.2 The Heart | 7.2 The Heart | 7.2 The Heart |
- The human heart is a double pump; the right side pumps blood to the lungs, and the left side pumps blood to the rest of the body.
- The heartbeat rate is under intrinsic and extrinsic control.
| - Why is the heart called a double pump?

7.3 Features of the Cardiovascular System | 7.3 Features of the Cardiovascular System | 7.3 Features of the Cardiovascular System |
- The pulse rate of a person indicates the heartbeat rate.
- Blood pressure accounts for the flow of blood in the arteries. Skeletal
muscular contraction, the presence of valves, and breathing movements
account for the flow of blood in the veins.
| - How does the pulse rate of a person indicates the heartbeat rate?

7.4 The Cardiovascular Pathways | 7.4 The Cardiovascular Pathways | 7.4 The Cardiovascular Pathways |
- The pulmonary arteries transport O2-poor blood to the lungs, and the pulmonary veins return O2-rich blood to the heart.
- The systemic circuit transports blood from the left ventricle of the heart to the body and then returns it to the right atrium of the heart.
| - What is the relative oxygen content of the blood flowing in the pulmonary artery compared to the pulmonary vein? Explain.

7.5 Lymphatic System | 7.5 Lymphatic System | 7.5 Lymphatic System |
- The lymphatic vessels form a one-way system, which transports lymph from the tissues and fat from the lacteals to certain cardiovascular veins.
- The lymphoid organs (red bone marrow, spleen, thymus, lymph nodes, and tonsils) play critical roles in defense mechanisms.
| - How does the lymphatic system assist the cardiovascular system?
Answer
- What role do lymphatic organs play in purifying the lymph and blood?
