Question 14

Flashcard 14:
- Q: What is the function of the left ventricle?

Answer 14

• A: To pump oxygenated blood through the aortic valve into the aorta.

Question 15

Flashcard 15:
- Q: What carries oxygenated blood from the lungs to the left atrium?

Answer 15

• A: The pulmonary veins.

Question 16

Flashcard 16:

Question 18

Flashcard 18:
- Q: How does the structure of arteries adapt for their function?

Answer 18

• A: Thick muscular walls to withstand high pressure and prevent bursting, and a small lumen to maintain high blood pressure.

Question 19

Flashcard 19:
- Q: How does the structure of veins adapt for their function?

Answer 19

• A: Large lumen for easy blood flow, one-way valves to prevent backflow, and thinner walls to allow skeletal muscles to squeeze veins.

Question 20

Flashcard 20:
- Q: How does the structure of capillaries adapt for their function?

Answer 20

• A: Very thin walls for easy diffusion, small endothelial gaps for exchange of materials, and smooth inner surface to reduce friction.

Question 21

Flashcard 21:
- Q: What is blood pressure?

Answer 21

• A: The pressure which the blood exerts against the wall of the blood vessel.

Question 22

Flashcard 22:
- Q: Describe the double circulatory system of a mammal.

Answer 22

• A: Blood is pumped through the heart twice during one complete journey around the body, separating oxygenated and deoxygenated blood.

Question 23

Flashcard 23:
- Q: What is the usual resting pulse rate for an adult?

Answer 23

• A: 60 to 100 beats per minute.

Question 24

Flashcard 24:
- Q: What are the likely causes of a heart attack?

Answer 24

Question 25

Flashcard 25:
- Q: What is the difference between a heart attack and a cardiac arrest?

Answer 25

• A: A heart attack is when a coronary artery becomes blocked, while a cardiac arrest is when the heart stops beating.

Question 26

Flashcard 26:
- Q: What are some preventative measures for heart disease?

Answer 26

• A: Follow a low cholesterol diet, avoid obesity, reduce stress, do not smoke, exercise regularly, reduce salt and sugar intake, and limit alcohol consumption.

Answer 28

• A: Lymphatic vessels and lymphatic nodes.

Question 29

Flashcard 29:
- Q: What are the functions of the lymphatic system?

Answer 29

Question 30

Flashcard 30:
- Q: What are the components of blood?

Answer 30

• A: Red blood cells, white blood cells, platelets, and plasma.

Question 31

Flashcard 31:
- Q: What is the function of red blood cells?
