1. What is Homeostasis, what part does Blood play in the Body maintaining Homeostasis?
2. List the 3 parts of Blood and what each are/contain.
3. Arteries and veins carry blood which direction and which carry oxygenated and Deoxygenated Blood?
4. What are the function of Capillaries?
5. What are the functions of the 5 valves involved in the hearts blood flow and list them. (5)
6. What does Pulmonary mean?
7. What do you think Coronary Arteries do?
8. What are the average number of heart beats/day/year?
9. Calculate your heart rate/minute
10. How many fluid gallons of blood does the Average heart move per day and per year?
11. What is the function of the Septum in our hearts?
1. Homeostasis is the body's ability to maintain a stable internal environment. Blood plays a crucial role in maintaining homeostasis by regulating body temperature, pH levels, and transporting nutrients and waste products.
2. The three parts of blood are red blood cells (which contain hemoglobin and carry oxygen), white blood cells (which are part of the immune system), and platelets (which help with blood clotting).
3. Arteries carry blood away from the heart, while veins carry blood back to the heart. Arteries carry oxygenated blood, while veins carry deoxygenated blood.
4. The function of capillaries is to allow for the exchange of nutrients, gases, and waste products between the blood and tissues.
5. The five valves involved in the heart's blood flow are the tricuspid valve, pulmonary valve, mitral valve, aortic valve, and the pulmonary semilunar valve. Their functions are to prevent the backflow of blood and regulate the flow of blood through the heart.
6. Pulmonary refers to the lungs.
7. Coronary arteries supply oxygen-rich blood to the heart muscle.
8. The average number of heartbeats per day is around 100,000, and per year is around 35 million.
9. To calculate your heart rate per minute, you can count the number of heartbeats in 60 seconds.
10. The average heart moves about 2,000 gallons of blood per day and around 730,000 gallons per year.
11. The septum in our hearts separates the left and right sides of the heart, preventing the mixing of oxygenated and deoxygenated blood.
