What is an adaptation of red blood cells that helps them carry oxygen?
1. contains haemoglobin to bind oxygen
2. is red in colour
3. carries oxygen from the heart
1. contains haemoglobin to bind oxygen
2. is red in colour
3. carries oxygen from the heart
The correct answer is 1. Red blood cells contain hemoglobin, a protein that binds and carries oxygen. This adaptation allows red blood cells to efficiently transport oxygen throughout the body. The red color of red blood cells is due to the iron-containing hemoglobin. While red blood cells do carry oxygen from the heart to the rest of the body, this is not an adaptation specific to red blood cells but rather their primary function.
What is the function of the coronary artery?
1. To carry blood to the rest of the body
2. To supply the lungs with oxygen and glucose.
3. To supply the heart tissue with oxygen and glucose.
1. To carry blood to the rest of the body
2. To supply the lungs with oxygen and glucose.
3. To supply the heart tissue with oxygen and glucose.
The correct answer is 3. The function of the coronary artery is to supply the heart tissue with oxygen and glucose. The coronary arteries are responsible for delivering oxygenated blood to the heart muscle, ensuring that it receives the necessary nutrients for proper functioning. They provide a crucial blood supply to the heart itself, separate from the arteries that carry blood to the rest of the body (systemic circulation).
