Which blood vessel takes deoxygenated blood from the rest of the body to the heart?
The blood vessel that takes deoxygenated blood from the rest of the body to the heart is the superior and inferior vena cava.
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
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.
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).
What is the job of the pulmonary artery?
The blood vessel that carries deoxygenated blood from the rest of the body back to the heart is called the superior vena cava and the inferior vena cava. These vessels are part of a larger network of veins known as the systemic circulation.
To find this answer, you can start by understanding the circulatory system. The circulatory system consists of the heart, blood vessels, and blood, and it plays a vital role in transporting oxygen, nutrients, hormones, and waste products throughout the body.
Next, focus on the specific function you are looking for — the vessel that takes deoxygenated blood from the body to the heart. Deoxygenated blood contains waste products, such as carbon dioxide, which need to be removed and replenished with fresh oxygen.
Knowing this, you can deduce that the blood vessel carrying deoxygenated blood to the heart must be a vein. Veins are responsible for returning blood to the heart, while arteries carry oxygenated blood away from the heart to the rest of the body.
Finally, recall that the circulatory system consists of two main circuits: the systemic circulation and the pulmonary circulation. The systemic circulation carries oxygenated blood from the heart to the body's tissues and organs, while the pulmonary circulation carries deoxygenated blood from the heart to the lungs to get oxygenated.
Since you are looking for the vessel that carries deoxygenated blood from the body to the heart, you can conclude that it belongs to the systemic circulation. In this case, the superior vena cava and inferior vena cava are the main veins responsible for returning deoxygenated blood to the heart from the upper and lower parts of the body, respectively.
Therefore, the answer to your question is that both the superior and inferior vena cava transport deoxygenated blood from the rest of the body to the heart.
