1. The risk for heart disease can increase even more when heredity combines with unhealthy lifestyle choices, such as smoking cigarettes and eating an unhealthy diet. Eating a diet high in saturated fats, trans fat, and cholesterol has been linked to heart disease and related conditions, such as atherosclerosis. Also, too much salt (sodium) in the diet can raise blood pressure. The 3 key rick factors that can cause a heart attack are high blood pressure, high cholesterol, and smoking.

2. The digestive system is responsible for taking whole foods and turning them into energy and nutrients to allow the body to function, grow, and repair itself.

3. The secretory pathway refers to the endoplasmic reticulum, Golgi apparatus and the vesicles that travel in between them as well as the cell membrane and lysosomes. It's named 'secretory' for being the pathway by which the cell secretes proteins into the extracellular environment.

4. Dissection is the dismembering of the body of a deceased animal or plant to study its anatomical structure. Helps students learn about the internal structures of animals. It helps people learn how the tissues and organs are interrelated, and gives them an appreciation of the complexity of organisms in a hands-on learning environment.

5. Red blood cells carry oxygen from our lungs to the rest of our bodies. Then they make the return trip, taking carbon dioxide back to our lungs to be exhaled.

6. Arteries deliver oxygen rich blood to the capillaries. Capillaries bring oxygen poor blood to the veins to convey back to the lungs and heart. Veins carry the blood back to the heart.

How did I do?
