IB SEHS TOPIC 2 STUDY GUIDE QUESTIONS AND ANSWERS
List the pathway of blood in your heart - CORRECT ANSWER✅✅1) Superior vena cava
2) Inferior Vena cava
3) Right atrium
4) Tricuspid valve
5) right ventricle
6) pulmonary artery
7) lung cappilaries
8) pulmonary vein
9) left atrium
10) mitral valve
11) left ventricle
12) aorta
Describe what happens when you inhale: - CORRECT ANSWER✅✅ribs push outward and diaphragm
downward to make the chest cavity larger so the lungs can inflate; the pressure around the lungs
decreases; air flows into the lungs
Describe what happens when you exhale: - CORRECT ANSWER✅✅ribs push inward and diaphragm
upward to make the chest cavity smaller so the lungs can deflate; the pressure around the lungs
increases; air flows out of the lungs
list the pathway of air through the respiratory system: - CORRECT ANSWER✅✅- Nasal/Oral Cavity
- Pharynx
- Larynx
- Trachea
- Bronchi
- Bronchiole
- Alveoli
, why does the respiratory rate increase during exercise? - CORRECT ANSWER✅✅exercise increases
heart rate = increases cellular respiration = more Oxygen = more energy (ATP) = more carbon dioxide
must be released
what are the 3 components of blood? - CORRECT ANSWER✅✅- blood cells (white leucocytes and red
erythrocytes), platelets, and plasma
discuss the role of plateletes - CORRECT ANSWER✅✅- help create scabs
- assist in repair following injury
list the synonym for white blood cells & their function - CORRECT ANSWER✅✅leucocytes, which are
involved in immune function and protecting the body from infection
list the synonym for red blood cells & their function - CORRECT ANSWER✅✅erythrocytes, which are
involved in transporting oxygen throughout the body
what is the protein in red blood cells that carries oxygen from the lungs to the muscles for cellular
respiration to occur to make energy? - CORRECT ANSWER✅✅hemoglobin (iron-rich pigment)
discuss the relationship between hemoglobin concentration, EPO, and performance - CORRECT
ANSWER✅✅If EPO is manipulated = more red blood cell production = increase of concentration of
hemoglobin = more oxygen transportation = improvement in aerobic exercise performance
compare an contrast arteries, veins, an cappilaries - CORRECT ANSWER✅✅arteries
- large in diameter
- thick, muscular walls
- more pressure
- move blood AWAY from heart
- fibrous
veins
