Spencer, Elisabeth test: circulatory system Flashcards
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
