Card preview (24)
14. What does blood contain when it flows into the right atrium from the body?
Little oxygen and a lot of carbon dioxide 68. WKST- the body transport system
12. What can you infer from the fact that your heart beats faster when you exercise?
When you exercise, your muscles need more oxygen 68. WKST- the body transport system
16. What does blood contain when it flows into the left atrium from the body?
A lot of oxygen and little carbon dioxide 69. WKST Blood and Lymph
24. What type of tissue in the heart pumps blood throughout the body?
Muscle tissue 69. WKST Blood and Lymph
26. What role does your brain play in the circulation of blood through your body?
It signals the heart to beat 68. WKST- the body transport system
31. Which chamber of the heart pumps oxygen-poor blood to the lungs?
Right ventricle 65. CLF exterior heart
34. Through which type of circulation does blood flow to from your heart to your lungs and back?
Pulmonary 66. CLF– Circulatory system overview
35. What would happen if your circulatory system did not deliver oxygen to your body’s cells?
Your body’s cells would die 69. WKST Blood and Lymph
36. Which of the following blood vessels allows diffusion to occur?
Capillaries 69. WKST Blood and Lymph
38. Which of these heart structures prevents blood from flowing backward?
Valve 69. WKST Blood and Lymph
43. What are the functions of the cardiovascular system?
Carrying oxygen, glucose, and other needed materials to the cells Carrying waste products away from cells Transporting cells that attack disease-causing microorganism 69. WKST Blood and Lymph
46. How does pulmonary circulation differ from systemic circulation?
Systemic circulation occurs throughout the body; pulmonary circulation occurs in the heart and lungs 69. WKST Blood and Lymph
47. What happens when blood is being pushed through the heart?
The atria fills with blood The valve between the ventricles and atria close Blood is pushed out of the heart 65. CLF exterior heart
48. What pumps blood to the lungs?
Right atrium 65. CLF exterior heart
50. As blood moves away from the heart, blood pressure does what?
Decreases 69. WKST Blood and Lymph
52. Blood flows from the heart to the body through what?
Arteries 65. CLF exterior heart
56. Blood that contains large amounts of carbon dioxide flows from the body into what atrium of the heart?
Right 72. Pathway of the circulatory system
57. Blood returns to the heart from the body through the blood vessel called what?
Vena cava 66. CLF– Circulatory system overview
61. The circulatory system carries the needed materials oxygen and what to the body cells?
Glucose nutrients 69. WKST Blood and Lymph
64. Substances are exchanged between the blood and body cells in the blood vessels known as what?
Capillaries 69. WKST Blood and Lymph
66. Fluid from the blood that enters lymphatic vessels is known as what?
Lymph 69. WKST Blood and Lymph
68. What is the septum and what is its function?
A hole in the septum would allow oxygen-poor blood to mix with oxygen-rich blood. As a result, less oxygen would go to the body’s cells 65. CLF exterior heart
69. What is the left ventricle? When blood enters this structure, is the blood low or high in oxygen?
blood entering the left ventricle is high in oxygen, be issue it has just come form the left atrium, which receives oxygen-rich blood from the lungs 72. Pathway of the circulatory system
72. What is the left atrium, and what are the blood lead into it? What is its level of oxygen content?
Pulmonary veins. High in oxygen 72. Pathway of the circulatory system
